The results showed that the expression of RGS16 had no significant effect on cell proliferation and apoptosis (Figures 9(a) and 10(a)), while the high expression of SNAI1, CDR2L, FRMD5, and FSTL3 could promote the proliferation of cancer cells and inhibit the apoptosis of cancer cells, but inhibiting their expression could inhibit the proliferation of cancer cells and promote the apoptosis of cancer cells (Figures 9(b)–9(e) and 10(b)–10(e)). The gene discussed is FSTL3; the disease is cancer.
