The current focus of my research the function of microRNAs in determining smooth muscle phenotype and the influence of signal transduction pathways on function of the miRNA induced silencing complexes (miRISC). Two miRNAs of current interest are miR-145 and miR-155. The miR-143~145 cluster regulates translation of messenger RNAs that code for transcriptional regulators of smooth muscle-restricted proteins. MiR-145 is emerging as a master regulator of structural protein composition of the vascular and airway walls. miR-155 is an important regulator of lung inflammation that is necessary for the innate immune response to allergens. We are testing the notion that miRNAs are important epigenetic regulators of protein expression that underlies adaptation of the cardiovascular, respiratory and immune systems to adapt to changes in environment. Such input varies under both normal and pathological conditions including vascular injury, hypertension and airways obstruction. These basic research problems led us to investigate ways to translate advances in microRNA biology to novel RNAi-based therapy of asthma and pulmonary hypertension.
