Berberine inhibited intestinal GUS activity. (A) Fecal pellets were collected to evaluate the GUS activity in mice after CPT11 and CPT11 + berberine treatment by 4-MUG assay. (B) The assessment of fecal pellets for GUS-producing bacteria was determined by culture with 4-MUG agar medium. (C) Mice were treated with CPT11 or CPT11 + berberine for 14 days; GUS activity was then imaged using the fluorescent substrate FDGlcU. Data were expressed as the mean ± SD (n = 3 per group). ##p < 0.01, ###p < 0.001 vs. the control group; **p < 0.01, ***p < 0.001 vs. CPT1 + berberine treated group.
