β‐Glucuronidase‐Expressing Lactobacillus reuteri Triggers Irinotecan Enterotoxicity Through Depleting the Regenerative Epithelial Stem/Progenitor Pool
26 Apr 2025
Abstract excerpt
Irinotecan (CPT11)-induced diarrhea affects 80-90% of cancer patients due to β-glucuronidase (GUS) converting 7-ethyl-10-hydroxycamptothecin glucuronide (SN38G) to 7-ethyl-10-hydroxycamptothecin (SN38). It remains unclear whether SN38 impacts the homeostasis between gut microbiota and mucosal stem cell niche. This study explores the crosstalk between gut microbiota and intestinal stem cells (ISCs) in intestinal...
