In the identified CD27, PD1, and PDL1 network (Figure 4A), multiple genes were associated with chemosensitivity or chemoresistance to cisplatin, docetaxel, erlotinib, etoposide, gefitinib, gemcitabine, paclitaxel, pemetrexed, and vinorelbine in the CCLE NSCLC cell lines (n = 117, Table 1). Here, CD274 is linked to non-small cell lung carcinoma.
