IH spore powder affects the intestinal microbiota and serum metabolites in B6/JGpt-Apcem1Cin(min)/Gpt (ApcMin/+) mice, a model of colorectal cancer, which in turn affects the JAK/STAT signaling and regulates the abundance of CD8+ T cells to suppress the development of colorectal cancer (CRC) [18]. This evidence concerns the gene GPT and colorectal cancer.
