Phenotypic plasticity is a cancer hallmark, and lung adeno-to-squamous transition (AST) triggered by LKB1 inactivation is significantly associated with drug resistance. Clinical data show that squamous transition occurs in certain lung adenocarcinoma patients who relapse from targeted therapy using EGFR tyrosine-kinase inhibitors (TKIs) or KRAS inhibitor. However, the epigenetic regulatory mechanisms involved in AST remain largely unknown. In a study published in the Journal of Experimental Medicine, researchers led by Prof. Ji Hongbin from the Center for Excellence in Molecular Cell Science, Shanghai Institute of Biochemistry and Cell Biology of Read More
