Another study with gastric cancer cells showed that lncRNA urothelial carcinoma associated 1 (UCA1) upregulates PD-L1 expression through sponging miR-214 and 193a, which usually target PD-L1 3′UTR, also contributing to cancer cell migration, invasion and drug resistance in gastric cancer [77]. The gene discussed is UCA1; the disease is gastric cancer.
