Data on Inflammatory Bowel Disease Reported by Researchers at Seoul National University (Vitamin D supplementation partially affects colonic changes in dextran sulfate sodium-induced colitis obese mice but not lean mice)
Obesity Daily News
2019 JUL 10 (NewsRx) -- By a News Reporter-Staff News Editor at Obesity Daily News -- Research findings on Digestive System Diseases and Conditions - Inflammatory Bowel Disease are discussed in a new report. According to news reporting originating in Seoul, South Korea, by NewsRx journalists, research stated, “Inflammatory bowel disease (IBD) often accompanies vitamin D deficiency, and vitamin D supplementation ameliorates IBD symptoms in animal models and humans. Because altered vitamin D metabolism has been reported in obesity, we hypothesized that the effects of vitamin D on the development of IBD would be different between obese and control mice.”
Financial support for this research came from Ministry of Education - Kingdom of Saudi Arabi.
The news reporters obtained a quote from the research from Seoul National University, “Five-week-old male C57BL/6N mice were divided into 4 groups and fed a diet differing in fat content (10% or 45%, normal diet [ND] or high-fat diet [HFD]) and vitamin D content (1000 or 10 000 IU/kg of diet, vDC or vDS) for 14 weeks. At week 13, colitis was induced by administration of 2% dextran sodium sulfate for 7 days. Histology score tended to be lower in the HFD-vDS group than HFD-vDC group, but there was no effect of vitamin D on the ND group. Colonic Cldn1 and Cyp27b1 mRNA levels were higher in the HFD-vDS than HFD-vDC group, but these effects of vitamin D were not observed in the ND group. The serum 25-hydroxy vitamin D levels were negatively correlated with the histology score in the HFD group but not in the ND group. Overall, these results suggest that vitamin D supplementation partially prevents the histological damage of the colon in obese mice but not in control mice.”
According to the news reporters, the research concluded: “This effect might be mediated by increased colonic Cyp27b1 levels, leading to upregulation of local 1,25-dihydroxy vitamin D production.”
