NR4A1 and gastric cancer: Further analysis revealed that differential RBPs (TAGLN2, TAGLN, SRSF6, PKM, SRSF2, NOC2L, IPO4, C1QBP, DHX9) may affect the anti-proliferative effect of nintedanib on gastric cancer cells by regulating downstream genes involved in cell proliferation and angiogenesis (NR4A1, BBC3, IFI27) through alternative splicing.
