Mirna

Mirna (microRNA) are small non-coding RNA molecules that have a key role in the regulation of gene expression. They are produced when longer, double-stranded RNA molecules (longer dsRNA) are processed as part of the RNA interference pathway. Mirnas are able to interact with mRNA molecules, blocking them from being translated into proteins. This regulation of gene expression makes mirnas important in the regulation of various cellular processes such as cell growth and differentiation, maintaining normal cellular physiology. They can also play a role in disease development. Given the importance of mirnas, they are now being studied as potential therapeutic targets for diseases such as cancer and diabetes.
