UCA1 and gastric cancer: For example, lncRNA UCA1 promotes proliferation, migration, and immune escape and suppresses apoptosis in gastric cancer by binding anti-tumor miRNAs [63]; lncRNA CYTOR promotes the resistance of tamoxifen in breast cancer cells via binding miR-125a-5p [64]; lncRNA RMRP promotes proliferation, migration, and invasion of bladder cancer via miR-206 [65].
