IL-23A promotes survival of GC cell lines through IL-17A/IL-17RA/NF-κB signaling. (A) The cell viability of SGC-7901 with the treatment was examined. (B) The cell viability of MKN45 with the treatment was examined. (C) The concentration of IL-17A in the cell culture medium of SGC-7901 and MKN45 were determined by ELISA. **P < 0.01. (D) The expression of IL-17RA and IL-23R in both MKN45 and SGC-7901. (E) The expression of p-IkBa, IkBa and CyclinD1 in both MKN45 and SGC-7901.
