Post-Transcriptional Gene Regulation by MicroRNA and RNA-Binding Protein
Recent advanced studies have demonstrated that post-transcriptional gene regulation is involved in many aspects of biological processes and in the pathogenesis of various types of disorders, such as neurodegenerative diseases, autoimmune diseases, and cancer. In addition to transcriptional regulation, spatially and temporally regulated gene expression is achieved by the post-transcriptional con...
متن کاملBioinformatics Methods for Studying MicroRNA and ARE-Mediated Regulation of Post-Transcriptional Gene Expression
MicroRNAs (miRNAs) are short single-stranded RNA molecules with 21-22 nucleotides that are known to regulate post-transcriptional expression of protein-coding genes involved in most of the cellular processes. Prediction of miRNA targets is a challenging bioinformatics problem. AU-rich elements (AREs) are regulatory RNA motifs found in the 3’ untranslated regions (UTRs) of mRNAs; they play domin...
متن کاملPost-transcriptional regulation of microRNA expression.
microRNAs (miRNAs) are endogenous, noncoding approximately 22-nucleotide RNA molecules that have recently emerged as fundamental, post-transcriptional regulators of cognate target gene expression. Many mammalian miRNAs are expressed in a tissue-specific manner, a phenomenon that has so far been attributed to transcriptional regulation. We here show by Northern blots and in situ hybridization ex...
متن کاملRNA Binding Protein-Mediated Post-Transcriptional Gene Regulation in Medulloblastoma
Medulloblastoma, the most common malignant brain tumor in children, is a disease whose mechanisms are now beginning to be uncovered by high-throughput studies of somatic mutations, mRNA expression patterns, and epigenetic profiles of patient tumors. One emerging theme from studies that sequenced the tumor genomes of large cohorts of medulloblastoma patients is frequent mutation of RNA binding p...
متن کاملPost-Transcriptional Regulation of Papillomavirus Gene Expression
Papillomavirus genomes are transcribed as one large complex transcription unit with multiple promoters, two poly(A) sites (early and late), and considerable alternative splicing. As a result, there are multiple opportunities for post-transcriptional regulation of papillomavirus gene expression. Although this area has not been as extensively studied as transcriptional regulation, there are a few...
