It is characterized by failure in immunoglobulin and protective antibody generation and defined by an increased tendency toward bacterial infections, autoimmunity, and malignancy. Most CVID diagnoses do not follow a classical Mendelian pattern of inheritance. In recent years, CVID has been considered an epigenetic phenomenon in the majority of cases, overtaking previous monogenetic and/or polygenetic theories. The aim of this study was to review the role of microRNAs (miRNAs) in CVID, focusing on the involvement of the same miRNAs in various non-infectious clinical complications of CVID, mainly autoimmunity and/or cancer. Materials and Methods: A bibliographic search of the scientific literature was carried out independently by two researchers in scientific databases and search engines. The MeSH terms “microRNAs” and “common variable immunodeficiency” were used. All research articles from inception to May 2020 were considered. Results: The literature data showed the involvement of two miRNAs in primary immunodeficiency: miR-142 and miR-155. Both of these miRNAs have been investigated through mice models, in which miR-142 and miR-155 were deleted. These knock-out (KO) mice models showed phenotypic analogies to CVID patients with hypogammaglobulinemia, adaptive immunodeficiency, polyclonal proliferation, lung disease, and enteric inflammation. miR-142 and miR-155 have been found to be involved in the following autoimmune and neoplastic clinical complications of CVID: Gastric cancer, gastric mucosa-associated lymphoid tissue (MALT) lymphoma, natural killer/Tcell lymphoma (NKTCL), and immune thrombocytopenia. Conclusions: miR-142 and miR-155 deregulation leads to similar CVID phenotypesin KO mice models. Although no data are available on the involvement of these miRNAs in human CVID, their dysregulation has been detected in human CVID comorbidities. The literature data show that miRNA sequences in murine models are comparable to those in humans; therefore, miR-142 and miR-155 involvement in human CVID could be hypothesized.

  • Cysteine-Rich 61 (Cyr61): a Biomarker Reflecting Disease Activity In
    Fan et al. Arthritis Research & Therapy (2019) 21:123 https://doi.org/10.1186/s13075-019-1906-y RESEARCHARTICLE Open Access Cysteine-rich 61 (Cyr61): a biomarker reflecting disease activity in rheumatoid arthritis Yong Fan†, Xinlei Yang†, Juan Zhao, Xiaoying Sun, Wenhui Xie, Yanrong Huang, Guangtao Li, Yanjie Hao and Zhuoli Zhang* Abstract Background: Numerous preclinical studies have revealed a critical role of cysteine-rich 61 (Cyr61) in the pathogenesis of rheumatoid arthritis (RA). But there is little literature discussing the clinical value of circulation Cyr61 in RA patients. The aim of our study is to investigate the serum Cyr61 level and its association with disease activity in RA patients. Methods: A training cohort was derived from consecutive RA patients who visited our clinic from Jun 2014 to Nov 2018. Serum samples were obtained at the enrollment time. To further confirm discovery, an independent validation cohort was set up based on a registered clinical trial. Paired serum samples of active RA patients were respectively collected at baseline and 12 weeks after uniformed treatment. Serum Cyr61 concentration was detected by enzyme-linked immunosorbent assay. The comparison of Cyr61 between RA patients and controls, the correlation between Cyr61 levels with disease activity, and the change of Cyr61 after treatment were analyzed by appropriate statistical analyses. Results: A total of 177 definite RA patients and 50 age- and gender-matched healthy controls were enrolled in the training cohort. Significantly elevated serum Cyr61 concentration was found in RA patients, demonstrating excellent diagnostic ability to discriminate RA from healthy controls (area under the curve (AUC) = 0.98, P < 0.001).

  • Salt-Inducible Kinases Dictate Parathyroid Hormone Receptor Action in Bone Development and Remodeling
    Salt-inducible kinases dictate parathyroid hormone receptor action in bone development and remodeling Shigeki Nishimori, … , Henry M. Kronenberg, Marc N. Wein J Clin Invest. 2019. https://doi.org/10.1172/JCI130126. Research In-Press Preview Bone Biology Endocrinology The parathyroid hormone receptor (PTH1R) mediates the biologic actions of parathyroid hormone (PTH) and parathyroid hormone related protein (PTHrP). Here, we showed that salt inducible kinases (SIKs) are key kinases that control the skeletal actions downstream of PTH1R and that this GPCR, when activated, inhibited cellular SIK activity. Sik gene deletion led to phenotypic changes that were remarkably similar to models of increased PTH1R signaling. In growth plate chondrocytes, PTHrP inhibited SIK3 and ablation of this kinase in proliferating chondrocytes rescued perinatal lethality of PTHrP-null mice. Combined deletion of Sik2/Sik3 in osteoblasts and osteocytes led to a dramatic increase in bone mass that closely resembled the skeletal and molecular phenotypes observed when these bone cells express a constitutively active PTH1R that causes Jansen’s metaphyseal chondrodysplasia. Finally, genetic evidence demonstrated that class IIa HDACs were key PTH1R-regulated SIK substrates in both chondrocytes and osteocytes. Taken together, our findings established that SIK inhibition is central to PTH1R action in bone development and remodeling. Furthermore, this work highlighted the key role of cAMP-regulated salt inducible kinases downstream of GPCR action.

  • ETV5 Links the FGFR3 and Hippo Signalling Pathways in Bladder Cancer Received: 2 December 2016 Erica Di Martino, Olivia Alder , Carolyn D
    www.nature.com/scientificreports OPEN ETV5 links the FGFR3 and Hippo signalling pathways in bladder cancer Received: 2 December 2016 Erica di Martino, Olivia Alder , Carolyn D. Hurst & Margaret A. Knowles Accepted: 14 November 2018 Activating mutations of fbroblast growth factor receptor 3 (FGFR3) are common in urothelial Published: xx xx xxxx carcinoma of the bladder (UC). Silencing or inhibition of mutant FGFR3 in bladder cancer cell lines is associated with decreased malignant potential, confrming its important driver role in UC. However, understanding of how FGFR3 activation drives urothelial malignant transformation remains limited. We have previously shown that mutant FGFR3 alters the cell-cell and cell-matrix adhesion properties of urothelial cells, resulting in loss of contact-inhibition of proliferation. In this study, we investigate a transcription factor of the ETS-family, ETV5, as a putative efector of FGFR3 signalling in bladder cancer. We show that FGFR3 signalling induces a MAPK/ERK-mediated increase in ETV5 levels, and that this results in increased level of TAZ, a co-transcriptional regulator downstream of the Hippo signalling pathway involved in cell-contact inhibition. We also demonstrate that ETV5 is a key downstream mediator of the oncogenic efects of mutant FGFR3, as its knockdown in FGFR3-mutant bladder cancer cell lines is associated with reduced proliferation and anchorage-independent growth. Overall this study advances our understanding of the molecular alterations occurring during urothelial malignant transformation and indicates TAZ as a possible therapeutic target in FGFR3-dependent bladder tumours. Fibroblast growth factors (FGF) and their four tyrosine kinase receptors (FGFR1-4) activate multiple downstream cellular signalling pathways, such as MAPK/ERK, PLCγ1, PI3K and STATs, and regulate a variety of physiolog- ical processes, encompassing embryogenesis, angiogenesis, metabolism, and wound healing1–3.

  • Eyeing the Cyr61/CTGF/NOV (CCN) Group of Genes in Development And
    Krupska et al. Human Genomics (2015) 9:24 DOI 10.1186/s40246-015-0046-y REVIEW Open Access Eyeing the Cyr61/CTGF/NOV (CCN) group of genes in development and diseases: highlights of their structural likenesses and functional dissimilarities Izabela Krupska1,3, Elspeth A. Bruford2 and Brahim Chaqour1,3,4* Abstract “CCN” is an acronym referring to the first letter of each of the first three members of this original group of mammalian functionally and phylogenetically distinct extracellular matrix (ECM) proteins [i.e., cysteine-rich 61 (CYR61), connective tissue growth factor (CTGF), and nephroblastoma-overexpressed (NOV)]. Although “CCN” genes are unlikely to have arisen from a common ancestral gene, their encoded proteins share multimodular structures in which most cysteine residues are strictly conserved in their positions within several structural motifs. The CCN genes can be subdivided into members developmentally indispensable for embryonic viability (e.g., CCN1, 2 and 5), each assuming unique tissue-specific functions, and members not essential for embryonic development (e.g., CCN3, 4 and 6), probably due to a balance of functional redundancy and specialization during evolution. The temporo-spatial regulation of the CCN genes and the structural information contained within the sequences of their encoded proteins reflect diversity in their context and tissue-specific functions. Genetic association studies and experimental anomalies, replicated in various animal models, have shown that altered CCN gene structure or expression is associated with “injury” stimuli—whether mechanical (e.g., trauma, shear stress) or chemical (e.g., ischemia, hyperglycemia, hyperlipidemia, inflammation). Consequently, increased organ-specific susceptibility to structural damages ensues. These data underscore the critical functions of CCN proteins in the dynamics of tissue repair and regeneration and in the compensatory responses preceding organ failure.

  • Migration Dichotomy of Glioblastoma by Interacting with Focal Adhesion Kinase
    Oncogene (2012) 31, 5132 --5143 & 2012 Macmillan Publishers Limited All rights reserved 0950-9232/12 www.nature.com/onc ORIGINAL ARTICLE EphB2 receptor controls proliferation/migration dichotomy of glioblastoma by interacting with focal adhesion kinase SD Wang1, P Rath1,2, B Lal1,2, J-P Richard1,2,YLi1,2, CR Goodwin3, J Laterra1,2,4,5 and S Xia1,2 Glioblastoma multiforme (GBM) is the most frequent and aggressive primary brain tumors in adults. Uncontrolled proliferation and abnormal cell migration are two prominent spatially and temporally disassociated characteristics of GBMs. In this study, we investigated the role of the receptor tyrosine kinase EphB2 in controlling the proliferation/migration dichotomy of GBM. We studied EphB2 gain of function and loss of function in glioblastoma-derived stem-like neurospheres, whose in vivo growth pattern closely replicates human GBM. EphB2 expression stimulated GBM neurosphere cell migration and invasion, and inhibited neurosphere cell proliferation in vitro. In parallel, EphB2 silencing increased tumor cell proliferation and decreased tumor cell migration. EphB2 was found to increase tumor cell invasion in vivo using an internally controlled dual-fluorescent xenograft model. Xenografts derived from EphB2-overexpressing GBM neurospheres also showed decreased cellular proliferation. The non-receptor tyrosine kinase focal adhesion kinase (FAK) was found to be co-associated with and highly activated by EphB2 expression, and FAK activation facilitated focal adhesion formation, cytoskeleton structure change and cell migration in EphB2-expressing GBM neurosphere cells. Taken together, our findings indicate that EphB2 has pro-invasive and anti-proliferative actions in GBM stem-like neurospheres mediated, in part, by interactions between EphB2 receptors and FAK.

A semiquantitative immunohistochemical analysis of 112 human glioma and normal brain specimens showed that levels of tumor-associated Cyr61 protein correlate with tumor grade (P < 0.001) and with c-Met protein expression (r2 = 0.4791, P < 0.0001). Purified HGF rapidly upregulated Cyr61 − mRNA (peak at 30 minutes) and protein expression (peak at 2 hours) in HGF /c-Met+ human glioma cell lines via a transcription- and translation-dependent mechanism. Conversely, HGF/c-Met pathway in- hibitors reduced Cyr61 expression in HGF+/c-Met+ human glioma cell lines in vitro and in HGF+/c-Met+ glioma xenografts. Targeting Cyr61 expression with small interfering RNA (siRNA) inhibited HGF-induced cell migration (P < 0.01) and cell growth (P < 0.001) in vitro. The effect of Cyr61 on HGF-induced Akt pathway activation was also examined. Cyr61 siRNA had no effect on the early phase of HGF-induced Akt phosphorylation (Ser473) 30 minutes after stimulation with HGF.
