OPEN ACCESS JOURNAL INIST-CNRS

Scope

The Atlas of Genetics and Cytogenetics in Oncology and Haematology is a peer reviewed on-line journal in open access, devoted to , cytogenetics, and clinical entities in cancer, and cancer-prone diseases. It is made for and by: clinicians and researchers in cytogenetics, molecular biology, oncology, haematology, and pathology. One main scope of the Atlas is to conjugate the scientific information provided by cytogenetics/molecular genetics to the clinical setting (diagnostics, prognostics and therapeutic design), another is to provide an encyclopedic knowledge in cancer genetics. The Atlas deals with cancer research and genomics. It is at the crossroads of research, virtual medical university (university and post-university e-learning), and telemedicine. It contributes to "meta-medicine", this mediation, using information technology, between the increasing amount of knowledge and the individual, having to use the information. Towards a personalized medicine of cancer.

It presents structured review articles ("cards") on: 1- Genes, 2- Leukemias, 3- Solid tumors, 4- Cancer-prone diseases, and also 5- "Deep insights": more traditional review articles on the above subjects and on surrounding topics. It also present 6- Case reports in hematology and 7- Educational items in the various related topics for students in Medicine and in Sciences. The Atlas of Genetics and Cytogenetics in Oncology and Haematology does not publish research articles.

Abstract Transcription The full-length SH3PXD2A transcript is 11264 nt in The TKS5 protein, encoded by the gene length. Multiple TKS5 isoforms arise as a result of SH3PXD2A, is a scaffolding protein essential for the alternative mRNA splicing involving exons 7 and formation of podosomes and invadopodia in 10, and alternative use of transcription start sites. untransformed cells and cancer cells, respectively. Podosomes and invadopodia (which collectively are Protein termed invadosomes) are actin-rich cellular protrusions capable of secreting proteolytic enzymes Description that can degrade the extracellular matrix. These The full-length SH3PXD2A transcript (TKS5- structures are thought to regulate cellular migration LONG or TKS5-ALPHA) is transcribed from a and invasion, as well as adhesion and the release of promoter upstream of exon 1 and is translated into a growth factors.

The SH3PXD2A locus encodes multiple TKS5 isoforms as a result of alternative splicing at exons 7 and 10 as well as alternative promoter usage. Genomic information was obtained from the UCSC genome browser (http://genome.ucsc.edu/). Short-form Tks5 (Tks5-short and Tks5-beta) have been reported by Li et al. (2013) and Cejudo-Martin et al. (2014).

At the cell membrane, TKS5 is thought to interact with multiple components of invadosomes Cytoplasmic and at invadosome foci. either directly or indirectly, and thereby mediates Function invadosome formation and maturation (Sharma et TKS5 was initially identified as a substrate for SRC al., 2013). These interacting partners includes (Lock et al., 1998), and was subsequently shown to adaptor proteins and actin regulatory proteins, such play a critical role in invadosome formation in as NCK1, NCK2, GRB2, CTTN (Cortactin), WASL multiple cell types (Courtneidge, 2011; Murphy and (N-WASP), ACTR2/ACTR3 (Arp2/3) complex, and Courtneidge, 2011; Paz et al., 2013). ARHGAP35 (p190RhoGAP) (Crimaldi et al., 2009; Full-length TKS5 functions as an adaptor for Oikawa et al., 2008; Stylli et al., 2009). TKS5 also recruiting other proteins to the cell membrane for interacts with NOXA1 and CYBA (p22phox), which invadosome formation. are components of the NADPH oxidase complex, The recruitment of TKS5 to the cell membrane and thereby promotes reactive oxygen species (ROS) depends on its PX domain and phosphorylation by production by NOX enzymes at invadosomes (Diaz Src (Abram et al., 2003). It has been proposed that et al., 2009; Gianni et al., 2010; 2009). ROS have phosphorylation of TKS5 releases its PX domain been shown to facilitate invadosome formation by from intramolecular interaction and allows TKS5 to maintaining or amplifying the phosphorylation of bind to cell membrane phosphatidylinositol lipids, TKS5. As such, TKS5 is thought to promote such as phosphatidylinositol-3,4-bisphosphate invadosome formation via ROS in a positive (PI(3,4)P2) (Abram et al., 2003; Oikawa et al., feedback loop.

The full-length TKS5 mRNA encodes a protein that contains a PX domain and five SH3 domains, as well as proline-rich regions (PxxP) and Src phosphorylation sites (Y). The various short isoforms lack the PX domain.

Finally, TKS5 has also been shown to interact with Homology members of the ADAM family metalloproteases, specifically ADAM12, ADAM15, ADAM19 TKS5 is homologous to SH3PXD2B (TKS4), (Abram et al., 2003). It is believed that Tks5 recruits another adaptor protein that functions as a Src theses proteases to the invadosome foci for substrate and promotes invadosome function processing growth factors and regulating cell (Buschman et al, 2009). TKS4 contains a PX domain motility. For example, ADAM12 has been shown to at the N-terminus and four SH3 domains in the C- promote ectodomain shedding of HBEGF (heparin- terminus. binding EGF-like growth factor) and enhance invadopodia formation in cancer cells (Diaz et al., Implicated in 2013). In the context of cancer, TKS5-dependent formation Breast cancer of invadopodia is thought to promote metastasis by TKS5 expression is increased in human primary mediating local tumor invasion and intravasation at breast tumors compared to normal tissues, and is the primary site, as well as extravasation and further increased in metastases (Stylli et al., 2014). colonization at the distant site (Murphy and TKS5 is required for invadopodia formation in Courtneidge, 2011; Paz et al., 2014). breast cancer cells (Seals et al, 2005). In the context of normal development, TKS5- TKS5-dependent invadopodia have been shown to depedent podosomes are important for mediating promote tumor growth in a transplantation setting, cell migration during embryogenesis. Knockdown of cancer cell intravasation and extravasation, and Tks5 in zebrafish led to impaired dorsal-ventral metastasis formation (Eckert et al., 2011; migration of neural crest cells and defective Gligorijevic et al., 2012; Leong et al., 2014; Blouw craniofacial structures and pigmentation (Murphy et et al., 2015). al., 2011). Similarly, genetic deletion of Tks5 in Expression of full-length TKS5 in human breast mice led to complete cleft of the secondary palate tumors correlated with poor prognosis (Blouw et al., and neonatal death (Cejudo-Martin et al., 2014). In 2015). addition, study in Xenopus showed that Tks5- Lung cancer dependent podosomes are also required for the TKS5 expression is increased in human lung tumors migration of neuronal growth cones (Santiago- compared to normal tissues (Stylli et al., 2014).

Furthermore, TKS5, shorter isoforms of TKS5 that lack the PX higher expression of full-length TKKS5 relative to domain have been reported (Lock et al, 1998; Li et short-form TKS5 correlated with poor survival of al., 2013; Cejudo-Martin et al., 2014). early-stage lung adenocarcinoma patients (Li et al., There are few reports on the functions of these short 2013). isoforms. Experiments in mouse lung cancer cell lines showed Melanoma that overexpression of a short isoform (Tks5-short) TKS5 is required for invadopodia formation in suppressed invadopodia function by disrupting the melanoma cells (Seals et al, 2005). stability of invadopodia (Li et al., 2013). In addition, overexpression of a short-form equivalent protein, Prostate cancer ΔPX-Tks5, in Xenopus neural crest cells inhibited TKS5 expression is increased in human prostate invadosome functions and impaired motoneuron tumors compared to normal tissues, and is required axon extension into the peripheral myotomal tissue for invadopodia function in prostate cancer cells in Xenopus embryos (Santiago-Medina et al., 2015). (Stylli et al., 2014; Burger et al., 2014). These data suggest that the short forms of TKS5 can Gliomas function as negative regulators of invadosomes.

SLPI, antimicrobial activity, anti-inflammatory Abstract activity, anti-tumoral activity. Secretory Leukocyte Peptidase Inhibitor (SLPI) functionality in health and disease: Secretory Identity Leukocyte Peptidase Inhibitor (SLPI) is a serine protease inhibitor of cathepsin G, trypsin and Other names: ALK1, ALP, HUSI, HUSI-I, BLPI, chymotrypsin, but primarily against neutrophil MPI, WAP4, WFDC4 elastase. Its major function is to inhibit inflammation HGNC (Hugo): SLPI by blocking the proteolytic activity of these Location: 20q13.12 chr20:43,881,055- 43,883,184 proteinases released by leukocytes and also through (reverse strand) down-modulation of several cytokines. The anti- inflammatory activity is also mediated by inhibition of the activation of the transcription nuclear factor DNA/RNA NF-kB. Some studies localized the molecule within Description the cytosol and in secondary granules of neutrophils. Because of this, it is believed that neutrophil-derived SLPI belongs to the whey acidic protein four- SLPI may regulate the protease/antiprotease balance disulfide core family of proteins. The human SLPI at sites of tissue inflammation. In relation with the gene is localized on chromosome 20q12-13.2 adaptive immune system, it was suggested that SLPI (Kikuchi et al. 1998). The SLPI gene consists of four modulates the cellular and humoral immune exons and three introns, it spans approximately 2.6 response, by decreasing the T cell proliferation and kb (Kikuchi et al. 1998; Stetler et al. 1986). The SLPI reducing the class switching. Also, it is known that gene is stable and seems to be nonpolymorphic (Abe this polycationic non-glycosylated peptide, displays et al. 1991). Though, it has the potential to be anti-microbial properties against bacteria, viruses (in modulated at both the transcriptional and post- particular HIV) and fungus. In summary, the SLPI is transcriptional levels (Abe et al. 1991). Up to date, it a pleitropic molecule, implicated in physiological has not been detected a state of SLPI deficiency. and pathological events, such as wound healing, However, patients with severe congenital pregnancy, chronic obstructive pulmonary disease, neutropenia (a primary immunodeficiency syndrome cancer, ischemia reperfusion injury and stroke, characterized by mutations in at least 6 different among others. Their detection in serum and genes) were found to have strongly reduced SLPI biological fluids may be useful as a biomarker to levels, being SLPI a key factor for the neutrophil diagnosis and prognosis for certain diseases. differentiation in the bone marrow (Klimenkova et al. 2014).

In vivo, it is produced in the lung by tracheal cells, being the half-life of the transcripts of serous glands and by clear bronchial cells. In male approximately 12 h. Close to the exon 1, SLPI gene (Ohlsson et al. 1995) and female (Moriyama et al. has four potential binding sites for transcription 1999) genital tracts, SLPI is located in seminal factor AP-1, three for AP-2 and one for plasma and cervical mucosa, respectively. C/EPB(Klimenkova et al. 2014). Also, Kikuchi et Furthermore, it is produced by the parotid glands, al., describes that SLPI has a promoter region which intestinal epithelial cells (Si-Tahar et al. 2000), renal has a recognition sequence for two transcription tubule cells (Ohlsson et al. 2001), keratinocytes factor, one of which is highly expressed in lung cell (Wiedow et al. 1998), beta cells of the pancreas lines, and the other in nonlung cell lines (Kikuchi et (Nystrom et al. 1999) and immune cells like al. 1997). neutrophils and alveolar macropaghes (Sallenave et al. 1997; Mihaila et al. 2001; Guerrieri et al. 2011). Protein The SLPI expression is modulated by different Description molecules. It has been shown that SLPI is up- regulated by LPS, IL-1beta, TNF-alpha, neutrophil SLPI is an 11,7 kDa molecular weight non- elastasa, alpha-defensins, surfactant protein A, glycosylated protein composed by 132 amino acids corticosteroid and progesterone (Sallenave et al. (Stolk et al. 1999). The amino acid sequence of SLPI 1994; Reid et al. 1999; Maruyama et al. 1994; generates a highly polycationic peptide with two Abbinante-Nissen et al. 1995; King et al. 2003; highly homologous domains. These two domains Velarde et al. 2005; van Wetering et al. 2000; (COOH and NH2 terminal domains) share around a Ramadas et al. 2009). Finally, apoptotic cells can 35% homology (Vogelmeier et al. 1996). Each upregulate SLPI production by macrophages (Odaka domain contains eight cysteine residues that form et al. 2003). four disulfide bonds, which helps to stabilize the In contrast, few factors can downmodulate the structure of the molecule (Grutter et al. 1988). These expression of SLPI. Among them, the most cysteine rich domains are also called WAP domains significant are IFNgamma and TGF-beta (Jaumann (Whey Acid Protein). Domain 2 was initially et al. 2000; Jin et al. 1997). described to bind and inhibit the serine proteases Although, the structure of SLPI seems to be stable, it such as trypsin and elastase, while the domain 1 was could be cleaved and inactive-ated by probably not inhibitory (Eisenberg et al. 1990; chymase(Belkowski et al. 2008), cathepsins B, L, S Meckelein et al. 1990). It has been proposed that this (Taggart et al. 2001), lipid peroxidation products last domain helps in the stabilization of the (Tomova et al. 1994) and Host dust mite 1 allergen complexes "SLPI:elastase". Also, it is believed that (Brown et al. 2003), among others(Weldon et al. the domain 1 mediates binding to heparin, and thus 2009). increases its antiprotease activity, probably as a result of a conformational change of the molecule Function (Faller et al. 1992). Antiprotease activity: The inhibition of protease Expression activity was described for C-terminus domain SLPI was first isolated from bronchial secretions against elastasa, cathepsin G, trypsin, chymotrypsin, (Hochstrasser et al. 1972; Ohlsson et al. 1976). Then tryptase and chymase (Williams et al. 2006). Thus, the SLPI was characterized by two groups of SLPI major function is inhibit inflammation by researchers, whom purified the molecule from the blocking the proteolytic activity of serine proteinases urine and (Seemuller et al. 1986) and the parotid released by leukocytes and also through blocking the gland secretions (Thompson et al. 1986). SLPI is LPS effects, such as the upregulation of several located in both, the extracellular matrix and the cytokines like TNFalpha, MCP-1 and IL-6 (Yang et intracellular compartments, suggesting that it could al. 2005; Jin et al. 1998; Taggart et al. 2005; Ashcroft exert autocrine and paracrine effects (Taggart et al. et al. 2000). SLPI acts locally to maintain a 2005). protease/antiprotease balance thereby preventing The expression of SLPI is constitutive as well as protease mediated tissue destruction (Vogelmeier et modulated by different factors. Constitutively SLPI al. 1990). In the lungs, the disturbance of this balance can be found in serum and in extravascular mucosal is responsible for various lung diseases, many of fluids. Thus, it is found around of 40 (26.1-65.0) which are initiated and maintained by the ng/ml in serum, 72 (0.4-250) ng/ml in bronchial recruitment and activation of neutrophils (Birrer et lavage fluid (Hollander et al. 2007), in exhaled al. 1994; Suter 1989). breath condensate (2.82 - 0.58 pg/ml) (Tateosian et Anti-inflammatory activity: SLPI has anti- al. 2012) and saliva (0.3-3.2 ug/ml) (Shugars et al. inflammatory activities not necessarily related to its

The anti- is well-established that human saliva inhibits HIV inflammatory activity is also mediated by inhibition infectivity in vitro (McNeely et al. 1995; of proteolytic degradation of IkB, an inhibitor of the Nagashunmugam et al. 1997; Shugars et al. 2001; nuclear factor NF-kB (Ashcroft et al. 2000; Samsom Malamud et al. 1992; Fultz 1986). The infection of et al. 2007). adherent primary monocytes with HIV-1 was It has been shown that over-expression of SLPI significantly suppressed in the presence of human inhibits NF-kB, which is a transcription factor of saliva [76-80]. Four in vitro studies have several pro-inflammatory mediators in pulmonary demonstrated that SLPI has anti-HIV-1 activity in inflammation (Henriksen et al. 2004). Currently, cells that included peripheral blood mononuclear there are some evidence that SLPI is rapidly taken up cells, purified primary T cells, and SupT1 cells, a by cells and is localized in the nucleus and cytoplasm lymphocyte-derived tumor cell line (Fultz 1986; (Taggart et al. 2002). In the cytoplasm, SLPI Hocini et al. 2000; Shugars et al. 1997; Skott et al. prevents degradation of several key proteins in the 2002). regulated activation of NF-kB, as IkBalpha, IkBbeta Evidence suggests that SLPI blocks HIV-1 and IRAK (IL-1-receptor-associated kinase) through internalization in a dose-dependent manner the ubiquitin-proteasome mechanism (Greene et al. (McNeely et al. 1997). McNeely et al. found that 2004; Taggart et al. 2002), that follows the activation SLPI inhibits a step of viral infection that occurs of NF-kB by LPS or LTA (lipoteichoic acids). Also after virus binding but before reverse transcription. it has been proposed that SLPI acting in the nucleus In a co-precipitation experiment, it was described a can bind to NF-kB consensus region of target genes 55-kDa cell surface protein from monocytes by (Taggart et al. 2005). The entering into the nucleus using anti-SLPI antibodies. For some authors, the occurs through a mechanism in which SLPI may interaction between HIV and CCR5 could be the traverse membranes, due to its cationic nature main target of SLPI (Naif et al. 1998). Other authors (favored by the high content of arginine and lysine) showed that SLPI interferes with HIV fusion with by interaction with the negatively charged the T-cell plasma membrane through binding to membrane. Independently of the mode of action, in scramblase 1, a membrane protein that interacts with vivo experiments have demonstrated anti- CD4 and controls the movement of the phospholipid inflammatory / pro-apoptotic activities in the lung, bilayer of the plasma membrane (Shugars et al. and in a variety of other organs. 1999). It was also demonstrated that in myeloid cell, Microbicidal activity: SLPI blocks viral entry/fusion as a result of binding - Against Bacteria: to annexin II (Ohlsson et al. 2001; Ma et al. 2004; SLPI displays anti-microbial properties in vivo and Drannik et al. 2011). This molecule is a macrophage in vitro (Sallenave 2002; Gomez et al. 2009). It has receptor that binds to phosphatidylserine moiety that been recently reported that mouse and even human HIV carries on its outer layer on exiting from an SLPI shows anti-bacterial activity against infected cell (Ohlsson et al. 2001; Drannik et al. mycobacteria and it constitutes a pattern recognition 2011; Ma et al. 2004). Furthermore, the elastase receptor (PRR), that not only kills the inhibiting activity of SLPI was not be essential for microorganism, but also facilitates their their anti-HIV-1 activity (McNeely et al. 1997). phagocytosis by murine and human macrophages - Against Fungi: (Nishimura et al. 2008; Gomez et al. 2009). Either C. albicans and Aspergillus fumigatus were sensitive the antimicrobial activity or PRR ability depends on to the antimicrobial activity of recombinant SLPI. the COOH terminal domain where the inhibitory This activity was localized to N-terminal domain of activity of serine proteases resides. The WAPs the molecule (Tomee et al. 1997). domains of the molecule are involved, and this is due Wound healing activity: The role of SLPI in tissue to cationic residues that allow the disruption of the repair was suggested by the observation that in membranes of target organisms (Verma et al. 2007; human, epithelial expression of SLPI is increased in Gomez et al. 2009; Nishimura et al. 2008). The damaged skin (Wingens et al. 1998). Studies in SLPI antimicrobial activity of human SLPI has been deficient mice demonstrated that SLPI has an described for various bacteria such as Pseudomonas essential role in wound healing (Ashcroft et al. aeruginosa, Staphylococcus aureus, Staphylococcus 2000). In the absence of SLPI, the animals presents epidermis (Wiedow et al. 1998; Wingens et al. a delay in cutaneous wound healing, which is 1998), Mycobacterium tuberculosis (Gomez et al. attributed to an increased and prolonged 2009), and Escherichia coli (Williams et al. 2006). inflammatory response during the repair process, Therefore this activity is against Gram negative and and a delay in the accumulation of the matrix.

In fact, the al. 2001; Clauss et al. 2005; Devoogdt et al. 2009) high SLPI expression was found in dendritic cells of independent of its antiprotease activity (Simpkins et mucosal lymph node and it was suggested that these al. 2008). However, in Lewis lung cancer cells, the dendritic cells regulate cellular activation to pro-tumoral activity was shown to be dependent on microbial products and maintain the tolerance its protease inhibitor activity (Devoogdt et al. 2003). threshold (Samsom et al. 2007). Also, it was described that SLPI plasma levels were Also, we have observed that SLPI decreases elevated in lung cancer patients (Zelvyte et al. 2004). lymphocyte proliferation, a phenomenon which More recently, low level of SLPI was detected in oral depends on the presence of monocytes (Guerrieri et squamous cell carcinoma compared with normal oral al. 2011). However, it is not possible to rule out a epithelium (Wen et al. 2011). Moreover, an inverse direct effect of SLPI on lymphocytes since it is able correlation was also reported between SLPI and to bind the receptors phospholipid scramblases 1 and histological parameters associated with tumor 4 on CD4 T cells (Py et al. 2009). On tonsillar cells, progression (Wen et al. 2011). Interestingly, SLPI SLPI inhibits B cells expressing activation-induced reduced the hepatic lung carcinoma metastasis cytidine deaminase, an enzyme involved in class (Wang et al. 2006). In breast tumors, the mRNA switching. expression of SLPI either increases or decreases Thus, the overall idea is that SLPI is a tolerigenic depending on the case (Kluger et al. 2004; Stoff- factor, that it is able to down modulate the innate and Khalili et al. 2005). Also in a breast tumor cell line, adaptive immune response. Moreover, recently it has the SLPI overexpressing cells did not develop been shown that the hyporesponsiveness of human tumors in mice (Amiano et al. 2013). This effect was buccal epithelium to microbial stimulation is a specific for this type of cell line, since colon tumor phenomenon that depends on SLPI expression. cells overexpressing SLPI, developed faster tumors (Menckeberg et al. 2015). than control cells. Moreover, the breast cancer cell Recently, it has been also described that SLPI, in line that overexpresses SLPI showed a decrease in E- conjunction of neutrophil DNA or cathepsin G and cadherin expression, pro-apoptotic effects and cell human neutrophil elastase, induced a marked cycle arrests. (Rosso et al. 2014). Interestingly, the production of type I interferon by plasmacytoid administration of these SLPI transfected cells, which dendritic cells (Skrzeczynska-Moncznik et al. 2012; do not develop tumor in immunocompetent mice, Skrzeczynska-Moncznik et al. 2013). inhibited the tumor growth and increased the On the other hand, it was found that SLPI inhibits the survival of mice that were inoculated with mock formation of neutrophil extracellular traps; transfected control cells. (Amiano et al. 2011). structures that are involved in the elimination of In ovarian cancer SLPI inhibits cell growth through microorganisms, and also in the presentation of an apoptotic pathway (Nakamura et al. 2008), while, autoantigens (Zabieglo et al. 2015). These findings it has been also described that over-expression of suggest a role of SLPI in autoimmune diseases. SLPI is capable of producing a more aggressive ovarian cancer in vitro and in vivo models Implicated in (Devoogdt et al. 2009). In fact, it was suggested that SLPI could be a useful diagnostic and prognostic Cancer tool in ovarian cancer (Carlson et al. 2013). The invasiveness of tumors occurs through The SLPI gene and the protein expression are infiltration of tumor cells into healthy tissue and by significantly lower in metastatic "head and neck angiogenesis, which is modulated by proteases and squamous cell carcinoma" compared with non- antiproteases released from tumor cells that carry out metastatic ones. Also, an inverse significant tissue remodeling. correlation with HPV status was found for this kind Many studies have shown that SLPI expression is of tumor (Hoffmann et al. 2013). Therefore, overall modulated in cancer. However, there has been these data suggests us that it is not possible to reported an increased or decreased expression profile generalize the findings related to SLPI expression of the protein depending on the type of tumor. and function in only a unique type of tumor, since its For example, SLPI expression is increased in expression and modulation seems to be tumor pancreatic (Iacobuzio-Donahue et al. 2003), thyroid specific. (Jarzab et al. 2005), cervix (Rein et al. 2004), Pregnancy endometrial (Zhang et al. 2002), ovarian (Israeli et al. 2005) and gastric cancer (Cheng et al. 2008). SLPI among others antimicrobial peptides seems to In contrast, it is weakly expressed in nasopharyngeal play a role in pregnancy. SLPI is produced by carcinoma (Sriuranpong et al. 2004; Huang et al. amnion epithelium and deciduas (King et al. 2007). 2012), bladder tumors (Liang et al. 2002) and some High levels of SLPI were found in the cervical breast carcinomas (Hu et al. 2004). As we mentioned mucus plug during human pregnancy. The SLPI above, in ovarian cancer, SLPI is over-expressed and mRNA expression was higher in the second and the is thought to have a carcinogenic function (Hough et third trimester when compared with the first one

(Itaoka et al. 2015). Thus, in amniotic fluid, its Chronic obstructive pulmonary concentration increases according to the period of disease (COPD) pregnancy and the highest levels is reached on the onset of labor (Denison et al. 1999). As SLPI is a Emphysema may be due to an imbalance in protease- natural antimicrobial molecule, it may be involved in antiprotease activity. Patients with COPD show high the prevention of uterine infection during pregnancy levels of SLPI compared with healthy subjects and labor, and be a modulator of inflammation in this (Hollander et al. 2007). Conversely, SLPI levels are stage. decreased during COPD exacerbations produced by bacterial infection or rhinovirus (Mallia et al. 2012). Autoimmunity High levels of SLPI have been observed in several Ischemia reperfusion injury autoimmune diseases. For example, it was observed It has been described a protective effect of SLPI in in: i) inflamed joint tissues in a rat model of arthritis different ischemia/reperfusion injury models, such (Song et al. 1999); ii) patients with primary Sjögren's as heart and liver (Amberger et al. 2002; Lentsch et syndrome (Maruyama et al. 1998); iii) immune cells al. 1999). We have also observed a beneficial effect infiltrating the corpus in autoimmune gastritis (Hritz of SLPI in kidney ischemia reperfusion injury et al. 2006); iv) macrophages, activated microglia, (unpublished result). Interestingly, in cardiac neuronal cells and astrocytes during experimental transplantation, null mice for SLPI had an impaired autoimmune encephalomyelitis (Mueller et al. function after cold ischemia unlike the wild type 2008).

Central Nervous System Ischemia Overall, these results highlight the in vivo In two rat models, one of focal cerebral ischemia immunosuppressive effect of SLPI. However, it has (Wang et al. 2003) and the other of spinal injury, it been also implicated in the pathogenesis of other was observed high levels of SLPI. The same was autoimmune diseases such as psoriasis. As we seen in ischemic stroke in humans (Ilzecka et al. mentioned above, Nestle et al. have demonstrated 2002). Interestingly, the administration of SLPI has that the IFNalpha, produced by plasmacytoid been shown to be neuroprotective in both models of dendritic cells in response to DNA structures, injury in rats (Wang et al. 2003; Hannila et al. 2013). containing the neutrophil serine protease cathepsin G Taking into account that the SLPI can promote (CatG) and SLPI was important in the development axonal regeneration, plus the evidence of their of psoriatic skin lesions (Skrzeczynska-Moncznik et neuroprotective effects, we could consider this al. 2013). In fact, the neutralization of SLPI reduces molecule as potential therapeutic tool for different the severity of experimental autoimmune nervous system diseases (Hannila 2014). encephalitis (Muller et al. 2012). Biomarker Tuberculosis It has been found that the determination of serum Exposure of murine peritoneal macrophages to SLPI levels could be useful as a marker of several Mycobacterium tuberculosis led to an increase in diseases, such as disease activity in systemic SLPI protein secretion (Ding et al. 2005) which sclerosis with interstitial lung disease (Aozasa et al. seems to be a pattern recognition receptor for 2012). Also, it has been suggested that a form of micobacterias and inhibits the growth of cleaved SLPI can reflect the disease activity of them(Nishimura et al. 2008; Gomez et al. 2009). In patients with allergic rhinitis and asthma (Belkowski plasma of tuberculosis patients, the SLPI and IFN- et al. 2009). It was also been proposed as a biomarker gamma levels were significantly higher compared in ovarian and gastric cancer (Devoogdt et al. 2009; with the levels found in healthy subjects. Moreover, Cheng et al. 2008), or to identify subjects at risk of a direct association between SLPI levels and the infections and malignant transformation due to HIV severity of tuberculosis was detected. The main infection (Nittayananta et al. 2013). Recently, it was protective cytokine in tuberculosis, IFN-gamma, proposed as a biomarker for acute kidney injury after decreased the expression of SLPI in healthy subjects transplantation (Wilflingseder et al. 2014). However, but not in tuberculosis patients, probably because of until now none of these assays have been introduced the low expression of IFN- gammaR detected in in the clinical settings. these patients (Tateosian et al. 2014).

Abstract Protein Review on SOCS2, with data on DNA, on the protein encoded, and where the gene is implicated. Description Keywords: SOCS2; proteasome; immune cell Reference sequence for SOCS2 protein: differentiation; neuronal development; NP_001257399.1. SOCS2 contains 198 amino acid inflammation; cancer; diabetes residues with a molecular weight of 22172 Da. SOCS2 belongs to the SOCS box family. SOCS2 Identity contains a C terminal SOCS box (residue 151-197) for ElonginB,C/Cullin5/Rbx2 interaction. The Other names: CIS-2, CIS2, Cish2, SOCS-2, SSI-2, unstructured N-terminal region (residue 1-47) and SSI2, STATI2 the SH2 domain (residue 48-156) is implicated in HGNC (Hugo): SOCS2 substrate interaction.

Diagram representing the structure of SOCS proteins. At least eight proteins belonging to the SOCS family of proteins are shown (upper panel). They are characterized by the presence of an SH2 central domain and the SOCS box domain at the C-terminus. A small domain called kinase inhibitory region (KIR), only found in SOCS1 and SOCS3, is shown as a small box at the N- terminal region. SOCS proteins can interact with phosphotyrosine phosphorylated proteins through their SH2 domain and with Elongin BC through their SOCS box domain. Other proteins containing a SOCS box domain but lacking a SH2 domain are also shown (lower panel). Adapted from Elliot and Johnston (Elliott and Johnston, 2004) with modifications.

Review on oculocutaneous albinism, with data on The overall prevalence of OCA2 is estimated to be clinics, and the genes involved. 1:36000 in USA, but it is a lot more common among the African Americans with a prevalence of 1:10000 Identity (Okoro, 1975). In fact, OCA2 affects 1 in 3900 of the population in the southern parts of Africa. Other names OCA3 or Rufous oculocutaneous albinism has been Albinism, Oculocutaneous Albinism type 1 (OCA1) estimated to affect 1:8500 individuals in Africa; Oculocutaneous Albinism type 2 (OCA2) however, it is very rare in any other populations as Oculocutaneous Albinism type 3 (OCA3) per published literature. OCA4 has been found to be Oculocutaneous Albinism type 4 (OCA4) the second largest rare form of albinism after OCA1 Oculocutaneous Albinism type 5 (OCA5) in Japan. The 3 other forms of OCA are very rare. Oculocutaneous Albinism type 6 (OCA6) There is a single report till date for OCA5 in a Oculocutaneous Albinism type 7 (OCA7) consanguineous Pakistani family [Kausar et al., Tyrosinase-Negative Albinism 2013]. A few distinct cases of SLC24A5 mediated Tyrosinase-Positive Albinism OCA6 - one from India, one from China, two Note patients from France, three from Portugal, one from Oculocutaneous Albinism (OCA) is a group of Belgium and one from Syria, have been reported till congenital developmental disorder characterized by date [Mondal et al., 2012; Wei et al., 2013; Fanny et complete or partial loss of melanin in skin, hair and al., 2014].

In fact, in Oculocutaneous Albinism type 4 (OCA4), India, a preponderance of homozygous mutations is Oculocutaneous Albinism type 5 (OCA5), found and OCA1 is caused majorly because of Oculocutaneous Albinism type 6 (OCA6) and founder mutations (Chaki et al., 2005; Chaki et al.

OCA is inherited in an autosomal recessive mode. OCA1 can be sub-classified into two categories - (a) However, recently, it has been hypothesized that the OCA1A: when the tyrosinase enzyme activity is clinical spectrum of OCA depends on the completely lacking, and (b) OCA1B: when some pigmentation threshold of the patient. In residual activity is retained. The visual acuity of the genotypically darker complexion individuals such as OCA1A patients is greatly reduced; the degree of in Africans, two mutations are needed to completely nystagmus, strabismus, photophobia are usually shut off the high pigmentation background; whereas severe and the translucent iris that appear pink early in individuals with lighter complexion such as in life, often become gray-blue with age. In case of Caucasians, OCA can be manifested by the presence OCA1A there is an absence of pigmentation of one mutation and one hypomorphic allele (Chiang throughout the patient's life. In contrast, in OCA1B, et al., 2008). although there is little or no apparent melanin at birth, progressive melanization might occur with Clinics time. The range of pigmentation in OCA1B varies from little cutaneous pigment to nearly normal skin OCA is characterized by partial or total absence of color and the phenotype is often influenced by melanin in the skin, hair and eyes at birth. The ethnicity. OCA1B is called 'yellow OCA' due to the absence of optimum content of melanin during color of the hair, produced by pheomelanin embryogenesis acts as a cue to trigger defects in eye synthesis. development that cannot be corrected.

The degree of severity of the eye features as well as skin pigmentation varies with the different subtypes Genes involved and of albinism. Due to loss of pigmentation, the iris proteins looks hazel or light blue or in extreme cases as in OCA1, it is translucent to such an extent that it Note appears pink or red in ambient light. The skin OCA can be classified into seven major types viz. remains white or only become slightly pigmented Oculocutaneous Albinism type 1 (OCA1), with time in case of OCA1 whereas the patients Oculocutaneous Albinism type 2 (OCA2), suffering from the other 3 types of albinism have Oculocutaneous Albinism type 3 (OCA3) and residual pigmentation and look pinkish or yellowish.

Policies- Instructions to Authors See http://documents.irevues.inist.fr/bitstream/handle/2042/48486/Instructions-to-authors.pdf Manuscripts submitted to the Atlas must be submitted solely to the Atlas. The Atlas publishes "cards", "deep insights", "case reports", and "educational items". Cards are structured review articles. Detailed instructions for these structured reviews can be found at: http://AtlasGeneticsOncology.org/Forms/Gene_Form.html for reviews on genes, http://AtlasGeneticsOncology.org/Forms/Leukaemia_Form.html for reviews on leukaemias, http://AtlasGeneticsOncology.org/Forms/SolidTumour_Form.html for reviews on solid tumours, http://AtlasGeneticsOncology.org/Forms/CancerProne_Form.html for reviews on cancer-prone diseases. According to the length of the paper, cards are divided, into "reviews" (texts exceeding 2000 words), "mini reviews" (between), and "short communications" (texts below 400 words). Deep Insights are written as traditional papers, made of paragraphs with headings, at the author's convenience. Case Reports in haematological malignancies are dedicated to recurrent –but rare- chromosomes abnormalities in leukaemias/lymphomas; see http://atlasgeneticsoncology.org//BackpageAuthors.html#CASE_REPORTS . It is mandatory to use the specific "Submissionformfor Case reports": see http://AtlasGeneticsOncology.org/Reports/Case_Report_Submission.html. Educational Items must be didactic, give full information and be accompanied with iconography. Research articlesThe Atlas of Genetics and Cytogenetics in Oncology and Haematology does not publish research articles. Authorship All authors should qualify for authorship according to the ICMJE criteria.
