Figure 3. Effects of linc00641 overexpression on viability and apoptosis. (A) Linc00641 expression was detected by real-time PCR in gastric cancer cells after linc00641 lentivirus infection. (B) Cell viability was tested by MTT assays. Linc00641 overexpression increased the viability of the gastric cancer cells. (C) Left panel: Cell apoptosis was detected by flow cytometry in gastric cancer cells 72 hours after linc00641 lentivirus infection. Linc00641 overexpression suppressed the apoptosis of the gastric cancer cells. Right panel: Quantification of the apoptosis results. *P < 0.05 compared with the control siRNA.
