The observation that FGFR pathway mutation is significantly associated with steroid metabolism activation, insulin receptor signaling pathway upregulation, cell cycle activation, and immune exclusion phenotype, inspired a rational hypothesis that anti-FGFR mutation may offer a way to tackle immune cell exclusion (including cytotoxic T cells and M1 macrophages) from the tumor center to boost tumor destruction via immunotherapy. The gene discussed is INSR; the disease is neoplasm.
