Description
Cell size is essential in a cell's cellular processes and function. Hence cell size andgrowth need to be appropriately maintained. Gene regulation plays a vital role inregulating gene expression of different cellular processes like apoptosis, cell growth,etc. MicroRNAs (miRNAs), small single-stranded RNAs, regulate gene expression post-transcriptionally by binding to the 3’ untranslated region (UTR) of their target messengerRNAs (mRNAs), degrade their target mRNA, and hence silence their gene expression.In a forward genetic screen, our lab has identified a micro-RNA that inhibits apoptosisin the Drosophila eye model. Previous study shows that in the hippo (hpo) mutantsexhibit overgrowth, whereas gain-of-function of hippo triggers cell death in thedeveloping eye. Our preliminary data suggest that the gain-of-function of miR-277 in theGMR>hpo background rescues Hpo-mediated cell death. In addition, the gain-of-function of miRNA-277 restores the impaired axonal targeting observed in GMR>hpoeye disc. Hence, our working model suggests that miRNA regulates cell growth bymodulating the hippo pathway.
