CHAF1B and gastric cancer: The results revealed that inhibition of lnc-CHAF1B-2 increased the proportion of cells in the Q2 quadrant, indicating increased apoptosis of gastric cancer cells, whereas overexpression of lnc-CHAF1B-2 slightly decreased the number of cells in the Q2 quadrant, thus suppressing cell apoptosis, as depicted in Fig. 3C.
