HCAR2 and colorectal adenoma: Collectively, our study indicated that SBJDD may exert its inhibitory effects on colorectal adenoma carcinogenesis by regulating gut microbiota, promoting the production of SCFAs, activating G protein-coupled receptors GPR43, GPR41 and GPR109a, inhibiting histone deacetylases HDAC1 and HDAC3, inducing M2-like macrophage polarization, reducing intestinal inflammation, inhibiting cancer cell proliferation and restoring intestinal barrier function.
