Welcome to the Goncharova Lab, part of UC Davis Health's Department of Internal Medicine and Division of Pulmonary, Critical Care and Sleep Medicine. Our research interests have focused on the molecular and cellular mechanisms of pulmonary hypertension. Our goals are:

- to dissect new signaling hubs driving hyper-proliferation of resident pulmonary vascular cells, pulmonary vascular remodeling and PAH;

- to identify and pre-clinically validate novel molecular target pathways for therapeutic intervention;

- to develop in vitro human-based models for molecular and pre-clinical studies.

Goncharova Lab Research Example

  1. The role of mTOR signaling network and growth suppressor TSC2 in pulmonary vascular cell reprograming, PA remodeling and right ventricular dysfunction in pulmonary arterial hypertension.
  2. The role of HIPPO signaling cassette in pulmonary vascular cell hyper-proliferation, development and progression of pulmonary hypertension.
  3. GATA6 transcriptional factor as a regulator of pulmonary vascular cell-cell communications, BMP signaling and inflammation in pulmonary hypertension.
  4. Lipid metabolism as a regulator of pulmonary vascular remodeling and pulmonary hypertension.
