Correlation analysis of differential gut microbiota, metabolites, and genes suggested that CH might inhibit prostate cancer growth by increasing the relative abundance of g_Blautia, g_Lactobacillus, and g_Butyricicoccus, suppressing g_Akkermansia proliferation, enhancing Acetylglycine metabolite production, upregulating Ttpa, Gm14964, Shc3, Elovl4 gene expression, and downregulating Gm10531, Bc021767 gene expression. Here, ELOVL4 is linked to Familial prostate cancer.
