Tubacin induces TFEB-dependent ferritinophagy independently of HDAC6 and sensitizes cancer cells to ferroptosis under GSH-GPX4 axis disruption.
Histone deacetylase 6 (HDAC6) is a promising therapeutic target in cancer. However, its inhibitors show limited efficacy as monotherapies and are more effective in combination settings, suggesting a context-dependent mechanism that remains poorly defined. Here, we show that tubacin sensitizes cancer cells to ferroptosi...
