In 2016, Fang et al. showed increased lncRNA UCA1 and decreased miR-27b in MDR gastric cancer cells such as SGC-7901/ADR, SGC-7901/DDP, and SGC- 7901/5-FU cells compared to their parental SGC-7901 cells, whereas knockdown of lncRNA UCA1 substantially restored miR-27b expression [90]. Here, UCA1 is linked to gastric cancer.
