The FEBS Journal, EarlyView.VA molecules alter VDAC1 gating by increasing anion flow and reducing cation permeability. In cancer cells, which rely on ER‐mitochondria Ca2+ transfer and overexpress VDAC1, this imbalance triggers bioenergetic stress, ROS buildup, and mitochondrial collapse, leading to cell death.
