Oligosaccharides of Polygonatum Cyrtonema Hua ameliorates dextran sulfate sodium-induced colitis and regulates the gut microbiota
Biomedicine &Amp; Pharmacotherapy, 161, 114562.
TL;DR:
Results showed that doses of PFOS alleviated the DSS-induced histopathological damage and improved intestinal barrier function, suggesting that PFOS might be used as an efficacious supplement for reducing inflammatory bowel disease.

Ulcerative colitis (UC) is one common chronic inflammatory bowel disease that causes severe side effects, and expensive treatment limits effective and sustained treatment of UC. Fructooligosaccharide was isolated from Polygonatum Cyrtonema Hua (PFOS) and exhibits anti-inflammatory effects. Therefore, we are curious whether PFOS could be used for the treatment of UC. PFOS was introduced via intragastric gavage to C57BL/6 J mice exposed to acute colitis induced by DSS. The results showed that doses of PFOS at 2 and 5 mg/kg/day alleviated the DSS-induced histopathological damage and improved intestinal barrier function. qPCR analysis revealed that PFOS exerted a significant downregulation of pro-inflammatory cytokines (TNF-α, IL-1β, and IL-6) and upregulation of antioxidant genes, including superoxide dismutase1 (SOD1), glutathion peroxidase2 (GPX2), and nuclear factor erythroid 2 related factor2 (Nrf2). Furthermore, PFOS suppressed the DSS-induced disruption of the mucosal barrier by downregulating MMP13. Moreover, using 16 S rRNA gene-based microbiota analysis, PFOS could selectively enhance the growth of probiotics, including Bifidobacterium, Alloprevofella, and Alistipes. Our findings indicated that PFOS attenuated DSS-induced colitis in mice, suggesting that PFOS might be used as an efficacious supplement for reducing inflammatory bowel disease.
