iRGD‐modified exosomes effectively deliver CPT1A siRNA to colon cancer cells, reversing oxaliplatin resistance by regulating fatty acid oxidation

Fatty acid oxidation (FAO) plays a vital role in drug resistance in cancer cells. Carnitine palmitoyltransferase 1A (CPT1A), a key enzyme of FAO, is widely recognized as an emerging therapeutic target. Here, we confirmed that CPT1A was heterogeneously expressed in colon cancer cells, with a high expression in oxaliplatin-resistant cells but low expression in oxaliplatin-sensitive cells, and expression could be increased by oxaliplatin...
