Regulators and mediators of the ER stress response

miRNA regulation of stress responses

 

Research Overview

 

A class of small RNAs, known as microRNAs (miRNAs), are critically involved in control of cell survival and cell death decisions. The main function of miRNAs is to direct posttranscriptional regulation of gene expression, typically by binding to 3’ UTR of cognate mRNAs. Our main goal is to evaluate the role of microRNAs in determining cell fate during conditions of ER stress. ER stress has been associated with a wide range of diseases, including neurodegeneration, stroke, bipolar disorder, cardiac disease, cancer, and diabetes. Identification of microRNAs involved in cellular response to ER-stress will reveal a level of molecular control that is well beyond the classical role of signaling pathways mediated by protein phosphorylation.
