My laboratory focuses on lung repair and pulmonary fibrosis. We are currently investigating molecular mechanisms implicated in the differentiation of lung fibroblasts into myofibroblasts during lung fibrosis, with particular emphasis on transcriptional and epigenetic mechanisms driving persistent fibrogenesis in idiopathic pulmonary fibrosis (IPF). We have recently discovered that in the lung, myofibroblast differentiation occurs through the engagement of chromatin modifier enzymes and epigenetic readers. We found that the histone methyltransferase G9a and the epigenetic reader CBX5 play a critical role in lung fibroblast activation, and that targeting these epigenetic modifiers enhanced mitochondrial function, blocked ECM protein secretion, and attenuated lung fibrogenesis.
In addition, my laboratory is interested in investigating the impact of aging on the development of pulmonary fibrosis. We have recently discovered that the endothelium of aged mouse lungs is dysfunctional and this abnormality leads to capillary loss and persistent lung fibrosis following injury. Using a multi-omics approach (RNA-seq, ATAC-seq, and scRNA-seq) we have identified transcriptional programs in lung endothelial cells orchestrating lung vascular repair and whose abnormal activation with aging leads to persistent lung fibrosis.
