Aldolase a coordinates macropinocytic nutrient scavenging and lysosomal degradation in lung cancer by interacting with V-ATPase

Our study identifies a novel, non-enzymatic function of ALDOA as a critical regulator of lysosomal degradation of macropinocytosed proteins via interaction with V-ATPase. This mechanism is essential for metabolic adaptation and growth of KRAS-mutant tumors under stress conditions. Targeting ALDOA offers a promising therapeutic strategy for cancers that rely on extracellular nutrient scavenging.
