Dr. Sahoo’s research is focused on microRNA-mediated pathogenesis of cardiovascular diseases, particularly pulmonary hypertension. MicroRNAs (miRNAs or miRs) are small (~19-25 nucleotides), non-coding endogenous RNA molecules that negatively regulate the expression of proteins via post-transcriptional modifications. A single miR can regulate multiple targets simultaneous and several miRs may modulate the function of a protein. The objective of these studies is to advance our understanding of molecular and signaling mechanisms in pulmonary vascular endothelial and smooth muscle cells; primary cells involved in vascular remodeling of the pulmonary microcirculation. The outcomes from these studies will provide insights into newer therapeutic targets for the management of cardiovascular diseases.
