ACTL6A regulates the Warburg effect through coordinated activation of AP-1 signaling in head and neck squamous cell carcinoma

ACTL6A drives hypoxic adaptation and glycolysis in head and neck squamous cell carcinoma by activating AP-1 signaling and chromatin remodeling, with a critical role in tumor metabolism.

• Why it matters: Understanding how tumors adapt to low-oxygen environments is essential for developing targeted therapies, especially since chromatin regulation of these processes remains poorly understood.
• What they did: The study used spatial biology and molecular analyses to show that ACTL6A overexpression enhances enhancer accessibility, promotes MAPK/ERK signaling, and sustains hypoxic gene expression in tumors.
• The result: Depleting ACTL6A disrupts hypoxic adaptation, reduces glycolysis, and creates metabolic vulnerabilities that sensitize tumors to specific inhibitors, offering new therapeutic avenues.
