Scientific summary

My research focuses on the molecular mechanisms involved in the structural and
metabolic remodeling underlying the pathogenesis of heart failure. I study the
role of SRF as a key regulator of cardiac genes that is repressed in different
models of cardiomyopathies and in human heart failure. Our group showed that
SRF is playing a key role for the maintenance of cardiac, visceral and arterial
smooth muscle contractility and endothelial cells angiogenesis. SRF co-regulates
genes encoding contractile proteins, notably all actin isoform, integrins and VEGF
signaling as well as energy metabolism and microRNAs. These results point to a
central role of SRF in the coupling of structure and energy metabolism, a
cornerstone for muscle tissues functions that is altered in genetic diseases like
dilated cardiomyoapthy and during ageing. More recently I identified defects in
NAD coenzyme metabolism in the failing heart of SRF Heart-KO mice and in
human failing hearts. My ongoing research program aims to restore NAD
homeostasis as a new therapeutic approach to cure heart failure.
