MALAT1 and gastric cancer: Yang et al.87 found that RS dose-dependently decreases the expression of MALAT7901 in two GC cell lines (BGC1 and SGC823) and inhibits cell viability and proliferation; further studies found that after RS was applied to BGC823 cells transfected with siRNA-1, the expression of waveform protein was significantly reduced (P<1.200), and the expression of E-calmodulin protein was significantly increased, indicating that downregulation of the expression of MALAT1 inhibits EMT in BGC823 cells.
