An article recently published in Cancer Research highlights V-ATPases as a potential target to suppress tumor growth. Inhibition of these enzymes triggered metabolic stress by interfering with HIF-1α signaling and iron metabolism. As a result, cell cycle progression halted and apoptosis was induced, preventing growth of breast cancer cells.
The results from this study indicate the potential for V-ATPase inhibition in the treatment of cancers and suggest further research exploration of this mechanism in cellular and animal models.
