CD79A and neoplasm: For example, it could promote the epithelial proliferation and turnover of mice by dampening the production of retinoic acid [45]; Oral administration of F. rodentium to the ApcMin/+ or azoxymethane- and dextran sulfate sodium-treated mice inhibited the growth of tumor [46]; F. rodentium could secrete functional factors to decrease the concentration of secretory IgA in feces, thus modulating the gut microbial composition [47].
