The modifier of mdg4, mod(mdg4), locus in Drosophila melanogaster represents a new type of complex gene in which functional diversity is resolved by mRNA trans-splicing. A protein family of >30 transcriptional regulators, which are supposed to be involved in higher-order chromatin structure, is encoded by both DNA strands of this locus. Mutations in mod(mdg4) have been identified independently ...
Many RNA-binding proteins including a master regulator of splicing in developing brain and muscle, polypyrimidine tract-binding protein 1 (PTBP1), can either activate or repress alternative exons depending on the pre-mRNA recruitment position. When bound upstream or within regulated exons PTBP1 tends to promote their skipping, whereas binding to downstream sites often stimulates inclusion. How ...
hypohidrotic ectodermal dysplasia (hed) is a rare congenital disorder arising from deficient development of ectoderm-derived structures including skin, nails, glands and teeth. the phenotype of hed is associated with mutation in eda, edar, edaradd and nemo genes, all of them disruptingnf-κb signaling cascade necessary for initiation, formation and differentiation in the embryo and adult. here w...
Following recruitment to solid tissues, peripheral blood monocytes express a number of proinflammatory molecules including TF, a trigger of coagulation that also promotes cell-cell interactions and tissue remodeling. Monocytes express two forms of TF: flTF, a highly coagulant transmembrane form, and asTF, a highly proangiogenic, soluble TF form. Biosynthesis of the two TF forms occurs via alter...
The splicing factor is important in cancer development, modulation numerous tumor suppressors and oncogenes, and regulation of multiple signaling pathways. Splicing factor 2/alternative splicing factor (SF2/ASF) is a proto‑oncogene, which has been implicated in the development of hepatocellular carcinoma. However, the underlying molecular mechanism remains to be elucidated. In the present study...
The T cell-surface glycoprotein CD6 is a modulator of cellular responses and has been implicated in several autoimmune diseases such as multiple sclerosis, rheumatoid arthritis, and psoriasis. During Ag presentation, CD6 is targeted to the immunological synapse in a ligand binding-dependent manner, in which CD6 domain 3 directly contacts CD166, expressed on the APC. T cell activation results in...
RNA splicing is the process of forming mature mRNA, which an essential phase necessary for gene expression and controls many aspects cell proliferation, survival, differentiation. Abnormal gene-splicing events are closely related to development tumors, generation oncogenic isoform in can promote tumor progression. As a main tumor-specific variants, alternative (AS) progression by increasing pro...
Galectins, galactoside-binding mammalian lectins: clinical application of multi-functional proteins.
Galectins are beta-galactoside binding mammalian lectins and they share homologous carbohydrate recognition domains. To date, 11 members of galectin family have been cloned and identified. They have been shown to play roles in diverse biological events, such as embryogenesis, oncogenesis, adhesion and proliferation of the cells, receptor for advanced glycation end products, mRNA splicing, bacte...
Knockdown of T-cell intracellular antigens TIA1 and TIAR contributes to a cellular phenotype characterised by uncontrolled proliferation and tumorigenesis. Massive-scale poly(A+) RNA sequencing of TIA1 or TIAR-knocked down HeLa cells reveals transcriptome signatures comprising genes and functional categories potentially able to modulate several aspects of membrane dynamics associated with extra...
We have identified 242 Anopheles gambiae genes from 18 gene families implicated in innate immunity and have detected marked diversification relative to Drosophila melanogaster. Immune-related gene families involved in recognition, signal modulation, and effector systems show a marked deficit of orthologs and excessive gene expansions, possibly reflecting selection pressures from different patho...
