Rational Engineering of Carboxylic Acid Reductase for Improved Catalytic Efficiency and Substrate Tolerance Enabling Green Vanillin Biosynthesis

Abstract Vanillin is a high-value natural aromatic compound widely used in food, flavor, and pharmaceutical fields. Carboxylic acid reductase (CAR)-catalyzed vanillic acid bioreduction offers a green vanillin biosynthesis route, yet low catalytic activity and severe substrate inh...

Drug-specific resistance mechanisms to RET inhibitors in RET fusion-positive NSCLC

Abstract Purpose: Ret proto-oncogene (RET) fusions are highly heterogeneous oncogenic drivers occurring in approximately 1-2% of non-small cell lung cancer (NSCLC). While selpercatinib and pralsetinib have dramatically improved clinical outcomes of patients, acquired resistance i...
