NR2F1 and gastric cancer: However, although knockdown of NR2F1-AS1 unexpectedly repressed the early apoptosis and the late apoptosis of GC cells (Fig. S1), it should be pointed out that knockdown of NR2F1-AS1 only inhibited the apoptosis of about 7–9% of GC cells, suggesting that NR2F1-AS1 regulates GC cell apoptosis locally but not extensively.
