However, a recent study showed that higher levels of swiprosin-1 and ABCC1 were found in cisplatin-resistant CL1-0 cells compared with the parental cells, indicating that swiprosin-1 promoted cisplatin resistance through activating ABCC1 for drug efflux in non-small cell lung cancer [27]. This evidence concerns the gene EFHD2 and non-small cell lung carcinoma.
