Abstract Background: Epstein-Barr virus (EBV) presumably plays an important role in the pathogenesis of nasopharyngeal carcinoma (NPC), but the molecular mechanism of EBV-dependent neoplastic transformation is not well understood. The combination of bioinformatics with evidences from biological experiments paved a new way to gain more insights into the molecular mechanism of cancer. Results: We profiled gene expression using a meta-analysis approach. Two sets of meta-genes were obtained. Meta-A genes were identified by finding those commonly activated/deactivated upon EBV infection/reactivation. -
Functions of Vertebrate Ferlins
cells Review Functions of Vertebrate Ferlins Anna V. Bulankina 1 and Sven Thoms 2,* 1 Department of Internal Medicine 1, Goethe University Hospital Frankfurt, 60590 Frankfurt, Germany; [email protected] 2 Department of Child and Adolescent Health, University Medical Center Göttingen, 37075 Göttingen, Germany * Correspondence: [email protected] Received: 27 January 2020; Accepted: 20 February 2020; Published: 25 February 2020 Abstract: Ferlins are multiple-C2-domain proteins involved in Ca2+-triggered membrane dynamics within the secretory, endocytic and lysosomal pathways. In bony vertebrates there are six ferlin genes encoding, in humans, dysferlin, otoferlin, myoferlin, Fer1L5 and 6 and the long noncoding RNA Fer1L4. Mutations in DYSF (dysferlin) can cause a range of muscle diseases with various clinical manifestations collectively known as dysferlinopathies, including limb-girdle muscular dystrophy type 2B (LGMD2B) and Miyoshi myopathy. A mutation in MYOF (myoferlin) was linked to a muscular dystrophy accompanied by cardiomyopathy. Mutations in OTOF (otoferlin) can be the cause of nonsyndromic deafness DFNB9. Dysregulated expression of any human ferlin may be associated with development of cancer. This review provides a detailed description of functions of the vertebrate ferlins with a focus on muscle ferlins and discusses the mechanisms leading to disease development. Keywords: dysferlin; myoferlin; otoferlin; C2 domain; calcium-sensor; muscular dystrophy; dysferlinopathy; limb girdle muscular dystrophy type 2B (LGMD2B), membrane repair; T-tubule system; DFNB9 1. Introduction Ferlins belong to the superfamily of proteins with multiple C2 domains (MC2D) that share common functions in tethering membrane-bound organelles or recruiting proteins to cellular membranes. Ferlins are described as calcium ions (Ca2+)-sensors for vesicular trafficking capable of sculpturing membranes [1–3]. -

ABSTRACT Lysyl oxidase (LOX) is an extracellular copper-dependent monoamine oxidase that catalyzes crosslinking of soluble collagen and elastin into insoluble, mature fibers. Lysyl oxidase-like proteins (LOXL), LOX isozymes with partial structural homology, exhibit similar catalytic activities. This review summarizes recent findings describing the roles of LOX family members in urological cancers and fibrosis. LOX/ LOXL play key roles in extracellular matrix stability and integrity, which is essential for normal female pelvic floor function. LOX/LOXL inhibition may reverse kidney fibrosis and ischemic priapism. LOX and LOXL2 reportedly promote kidney carcinoma tumorigenesis, while LOX, LOXL1 and LOXL4 suppress bladder cancer growth. Multiple studies agree that the LOX propeptide may suppress tumor growth, but the role of LOX in prostate cancer remains controversial. -
Extrinsic Regulators of Mrna Translation in Developing Brain: Story of Wnts
cells Article Extrinsic Regulators of mRNA Translation in Developing Brain: Story of WNTs Yongkyu Park * , Midori Lofton , Diana Li and Mladen-Roko Rasin * Department of Neuroscience and Cell Biology, Robert Wood Johnson Medical School, Rutgers University, Piscataway, NJ 08854, USA; [email protected] (M.L.); [email protected] (D.L.) * Correspondence: [email protected] (Y.P.); [email protected] (M.-R.R.) Abstract: Extrinsic molecules such as morphogens can regulate timed mRNA translation events in developing neurons. In particular, Wingless-type MMTV integration site family, member 3 (Wnt3), was shown to regulate the translation of Foxp2 mRNA encoding a Forkhead transcription factor P2 in the neocortex. However, the Wnt receptor that possibly mediates these translation events remains unknown. Here, we report Frizzled member 7 (Fzd7) as the Wnt3 receptor that lays downstream in Wnt3-regulated mRNA translation. Fzd7 proteins co-localize with Wnt3 ligands in developing neo- cortices. In addition, the Fzd7 proteins overlap in layer-specific neuronal subpopulations expressing different transcription factors, Foxp1 and Foxp2. When Fzd7 was silenced, we found decreased Foxp2 protein expression and increased Foxp1 protein expression, respectively. The Fzd7 silencing also dis- rupted the migration of neocortical glutamatergic neurons. In contrast, Fzd7 overexpression reversed the pattern of migratory defects and Foxp protein expression that we found in the Fzd7 silencing. We further discovered that Fzd7 is required for Wnt3-induced Foxp2 mRNA translation. Surprisingly, we also determined that the Fzd7 suppression of Foxp1 protein expression is not Wnt3 dependent. In conclusion, it is exhibited that the interaction between Wnt3 and Fzd7 regulates neuronal identity and the Fzd7 receptor functions as a downstream factor in ligand Wnt3 signaling for mRNA translation. -

Here we report a single-cell transcriptomic survey of aortas and coronary arteries in young and old cynomolgus monkeys. Our data define the molecular signatures of specialized arteries and identify eight markers discriminating aortic and coronary vasculatures. Gene network analyses characterize tran- scriptional landmarks that regulate vascular senility and position FOXO3A, a longevity- associated transcription factor, as a master regulator gene that is downregulated in six subtypes of monkey vascular cells during aging. Targeted inactivation of FOXO3A in human vascular endothelial cells recapitulates the major phenotypic defects observed in aged monkey arteries, verifying FOXO3A loss as a key driver for arterial endothelial aging. Our study provides a critical resource for understanding the principles underlying primate arterial aging and contributes important clues to future treatment of age-associated vascular disorders. 1 CAS Key Laboratory of Genomic and Precision Medicine, Beijing Institute of Genomics, Chinese Academy of Sciences, Beijing 100101, China. -

5' Untranslated Region Elements Show High Abundance and Great

Several ABCA genes are causatively linked to inborn diseases, and the role in cancer progression and metastasis is studied intensively. The regulation of translation initiation is implicated as the major mechanism in the processes of post-transcriptional modifications determining final protein levels. In the current bioinformatics study, we mapped the features of the 50 untranslated regions (50UTR) known to have the potential to regulate translation, such as the length of 50UTRs, upstream ATG codons, upstream open-reading frames, introns, RNA G-quadruplex-forming sequences, stem loops, and Kozak consensus motifs, in the DNA sequences of all members of the subfamily. Subsequently, the conservation of the features, correlations among them, ribosome profiling data as well as protein levels in normal human tissues were examined. The 50UTRs of ABCA genes contain above-average numbers of upstream ATGs, open-reading frames and introns, as well as conserved ones, and these elements probably play important biological roles in this subfamily, unlike RG4s. -
(Numbl) Downregulation Increases Tumorigenicity, Cancer Stem Cell-Like Properties and Resistance to Chemotherapy

Numb is a protein involved in cell development, in cell adhesion and migration, in asymmetric cell division, and in targeting proteins for endocytosis and ubiquitination. NumbL exhibits some overlapping functions with Numb, but its role in tumorigenesis is not fully known. Here we showed that the downregulation of NumbL alone is sufficient to increase NICD nuclear translocation and induce Notch pathway activation. Furthermore, NumbL downregulation increases epithelial-mesenchymal transition (EMT) and cancer stem cell (CSC)-related gene transcripts and CSC-like phenotypes, including an increase in the CSC-like pool. These data suggest that NumbL can act independently as a tumor suppressor gene. Furthermore, an absence of NumbL induces chemoresistance in tumor cells. An analysis of human tumors indicates that NumbL is downregulated in a variable percentage of human tumors, with lower levels of this gene correlated with worse prognosis in colon, breast and lung tumors. -
Molecular Structure of a Novel Cholesterol-Responsive a Subclass ABC Transporter, ABCA9

Kaminski,1 Juurgen€ J. Wenzel, Thomas Langmann, and Gerd Schmitz* Institute for Clinical Chemistry and Laboratory Medicine, University of Regensburg, Franz-Josef-Strauß-Allee 11, D-93042, Regensburg, Germany Received 25 May 2002 Abstract We recently identified a novel ABC A subclass transporter, ABCA6, in human macrophages. Here, we report the molecular cloning of an additional ABC A subfamily transporter from macrophages denoted ABCA9. The identified coding sequence is 4.9 kb in size and codes for a 1624 amino acid protein product. In accordance with the proposed nomenclature, the novel transporter was designated ABCA9. The putative full-length ABC transporter polypeptide consists of two transmembrane domains and two nu- cleotide binding folds and thus conforms to the group of full-size ABC transporters. We identified alternative ABCA9 mRNA variants in human macrophages that predict the existence of three truncated forms of the novel transporter. Among the human ABC A subfamily transporters, ABCA9 exhibits the highest amino acid sequence homology with ABCA8 (72%) and ABCA6 (60%), respectively. The striking amino acid sequence similarity between these transporter molecules supports the notion that they represent an evolutionary more recently emerged subgroup within the family of ABC A transporters, which we refer to as ‘‘ABCA6-like transporters.’’ ABCA9 mRNA is ubiquitously expressed with the highest mRNA levels in heart, brain, and fetal tissues.
