Identifying The Enzyme Involved In Vacuolar Atpase Acetylation During Doxorubicin-Induced Cardiotoxicity, Rebecca Dang, Tianqing Peng

Doxorubicin is an established anticancer medication infamous for its bright colouration and extremely toxic side effects. Emerging studies support that the imbalance between acetylation and deacetylation disrupts the autophagic flux leading to doxorubicin-induced cardiotoxicity. Vacuolar ATPases are a family of electrogenic proton pumps present on the lysosomal membrane that create an acidic environment for proteases to degrade proteins. Our preliminary study found that acetylated Vacuolar ATPase subunit V0 D1 levels increased in doxorubicin-injected mouse hearts. However, it is unknown how acetylation of subunit V0 D1 is modulated and whether this modification plays a role in doxorubicin-induced cardiotoxicity.
