In particular, Liu et al. revealed that vincristine (VCR)-induced gastric cancer multi drug resistant (MDR) cells, SGC7901/VCR, as compared to a sensitive one, SGC7901, showed a higher level of DJ-1 associated with an increased survival and resistance to several other chemotherapeutics such as Adriamycin, 5-Fluorouracil, and Cisplatin, a phenomenon that was ascribed to the upregulation of P-gp and Bcl-2 [3]. This evidence concerns the gene PARK7 and gastric cancer.
