DBF4 and colorectal carcinoma: Furthermore, A. muciniphila administration induced more Ki67+ proliferating cells, higher PCNA expression and elevated gene expression of proliferation-associated molecules including Snrpd1, Dbf4 or S100A9. At early stage of CRC development, in comparison with controls, the mice receiving A. muciniphila administration also had more body weight loss and shorter colon length, as well as higher gene expression of inflammatory cytokines.
