MicroRNA biogenesis, functionality and cancer relevance.
BACKGROUND MicroRNAs (miRNA) are small non-coding RNAs that negatively regulate gene expression in a sequence- specific manner. Post-transcriptional silencing of target genes by miRNA occurs either by specific cleavage of homologous mRNA or by specific inhibition of protein synthesis. MiRNAs are essential regulators of various processes such as proliferation, differentiation, development, cell ...
متن کاملMicroRNA biogenesis and cancer.
MicroRNAs (miRNA) are a recently discovered family of short non-protein-coding RNAs that negatively regulate gene expression. Recent studies of miRNAs highlight a requirement for cell viability. Posttranscriptional silencing of target genes by miRNAs occurs either by targeting specific cleavage of homologous mRNAs, or by targeting specific inhibition of protein synthesis. We recently identified...
متن کاملMicroRNA: Biogenesis, Function and Role in Cancer
MicroRNAs are small, highly conserved non-coding RNA molecules involved in the regulation of gene expression. MicroRNAs are transcribed by RNA polymerases II and III, generating precursors that undergo a series of cleavage events to form mature microRNA. The conventional biogenesis pathway consists of two cleavage events, one nuclear and one cytoplasmic. However, alternative biogenesis pathways...
متن کاملmicroRNA biogenesis and senescence
senescence acts as a physiological barrier against uncontrolled proliferation of cells with potentially harmful alterations, contributing to tumor suppression and tissue homeostasis in live organisms [1]. Senescence is a complex phenotype that involves major changes in cellular function and structure. This phenotype is characterized by a specific gene expression program, which is controlled by ...
متن کاملMicroRNA biogenesis and variability.
MicroRNAs (miRNAs) are cell-endogenous small noncoding RNAs that, through RNA interference, are involved in the posttranscriptional regulation of mRNAs. The biogenesis and function of miRNAs entail multiple elements with different alternative pathways. These confer a high versatility of regulation and a high variability to generate different miRNAs and hence possess a broad potential to regulat...
