MicroRNAs (miRNA) are non-coding RNAs, the majority of which are 22 nucleotide in size. They regulate gene transcription and control more than 50% of the mammalian genome. Although functional significance and targets of several miRNAs are yet to be identified, they may be regarded as controller of cellular physiology and function. Through such regulation they play vital roles in normal and diseased...
Ever since the discovery of small non-coding RNAs, microRNAs have been identified to play a critical role in development and function of pancreatic insulin-producing beta cells. Research carried out until now demonstrates that microRNAs can specifically target key pancreatic transcription factors and signalling molecules. This in turn may influence changes in insulin production and secretion. microRNAs...
MicroRNAs (miRNAs) are endogenous single-stranded non-coding RNAs of about - 22 nucleotides which suppress gene expression by selectively binding to the 3’ non coding region (3’-UTR) of specific messenger RNAs through base-pairing. There are now more than 1600 human miRNAs annotated in the miRNA registry (http://microrna.sanger.ac.uk), but, at the moment, very few miRNAs have been well characterized...
MicroRNAs belong to a family of small (-23 nt) non-coding RNAs that mediate posttranscriptional gene silencing. They are emerging as important new regulators of differentiation and development. Knowledge of their role in pancreas and islet development, may help in developing a regenerative therapy for diabetes mellitus, a metabolic disorder affecting hundreds of millions of people worldwide. In this...
Angiogenesis is the pathological process of forming new blood vessels from pre-existing vessels. It is one of the main features of many conditions such as cancer and inflammatory diseases. MicroRNAs (miRNAs) are small non-coding RNAs that regulate post-transcriptional gene expression. Recent studies have suggested that miRNAs play a significant role in angiogenesis. The study from Wang et al reported...
