Cardiolipin (CL), the signature phospholipid of mitochondrial membranes, is important for cardiovascular health. Perturbation of CL metabolism is implicated in cardiovascular disease (CVD). The link between CL and CVD may be explained by the physiological roles of CL in pathways that are cardioprotective, such as autophagy/mitophagy and the mitogen-activated protein kinase (MAPK) pathways. My dissertation work focuses on elucidating how CL influences mitophagy and MAPK pathways.

crd1Δ was synthetically lethal/sick with the general autophagy mutants atg8Δ, atg18Δ and mitophagy mutant atg32Δ, suggesting that autophagy/mitophagy may be deficient in cells lacking CL. Microscopic examination of mitophagy revealed decreased ...
