Fang et al. have revealed that lncRNA UCA1 functions as a sponge of miR-27b to down-regulate caspase-3 expression and inhibit extrinsic apoptosis pathway, thereby inducing the resistance of gastric cancer cells to DDP, adriamycin (ADR), and 5-fluorouracil (5-FU). The gene discussed is UCA1; the disease is gastric cancer.
