Targeting SERCA2 in Anti-Tumor Drug Discovery

SERCA2, a P-type ATPase located on the endoplasmic reticulum of cells, plays an important role in maintaining calcium balance within cells by transporting calcium from the cytoplasm to the endoplasmic reticulum against its concentration gradient. A multitude of studies have demonstrated that the expression of SERCA2 is abnormal in a wide variety of tumor cells. Consequently, research exploring compounds that target SERCA2 may offer a promising avenue for the development of novel anti-tumor drugs. This review has summarized the anti-tumor compounds targeting SERCA2, including thapsigargin, dihydroartemisinin, curcumin, galangin, etc. These compounds interact with SERCA2 on the endoplasmic reticulum membrane, disrupting intracellular calcium ion homeostasis, leading to tumor cell apoptosis, autophagy and cell cycle arrest, ultimately producing anti-tumor effects. Additionally, several potential research directions for compounds targeting SERCA2 as clinical anti-cancer drugs have been proposed in the review. In summary, SERCA2 is a promising anti-tumor target for drug discovery and development.
