Abstract

Lung cancer, in particular, non-small cell lung cancer (NSCLC), is the leading cause of cancer-related mortality. Cis-Diamminedichloroplatinum (cisplatin, CDDP) as first-line chemotherapy for NSCLC, but resistance occurs frequently. We previously reported that Tripartite motif protein 25 (TRIM25) was highly expressed in cisplatin-resistant human lung adenocarcinoma A549 cells (A549/CDDP) in comparison with its parental A549 cells. Herein, we take a further step to demonstrate the association of TRIM25 and cisplatin resistance and also the underlying mechanisms. Knockdown of TRIM25 by RNA interference in A549/CDDP cells decreased half maximal inhibitory concentration (IC
