Bacteroides fragilis ZY-312 activates Erk signaling and promotes proliferation in antibiotic-associated diarrhea (AAD) rats. (A,B) Cell proliferation marker Ki67 and p-ERK1/2 were detected by immunohistochemistry in colon sections on days 11 and 17 in all groups as mentioned in Figure 5A. All images were taken at the same magnification at 40×. (C) Phosphorylation of extracellular signal-related kinase (ERK), c-Jun N-terminal kinase (JNK), and p38 was also detected by western blot in colon tissues on day 11 in all groups as mentioned in Figure 5A.
