Cure8 research brief
This mouse study connects fat malabsorption, increased gut permeability, microbiome shifts, and reduced oxalate transport to higher oxalate absorption and kidney injury—mechanisms relevant to enteric hyperoxaluria seen in IBD.
Researchers (microbiome, oxalate metabolism), clinicians treating IBD patients with kidney stones or hyperoxaluria, translational scientists.
This study used the SAMP1/YitFc mouse model of spontaneous ileitis to investigate enteric hyperoxaluria (EH).
Mice fed high-fat diets with added oxalate had higher plasma and urinary oxalate and showed stool lipid changes consistent with fat malabsorption, reduced intestinal tight-junction proteins, increased markers of permeability (sucralose excretion), altered gut microbiome pathways, reduced ileal SLC26A6 expression, and progressive kidney inflammation.
Animal-model (SAMP1/YitFc) study reported in Gut Microbes via PubMed. Mouse findings may not directly predict human outcomes; the work is mechanistic/basic science.

The work links climate and sociodemographic context to IBD burden in tropical regions, which can influence diagnostic recognition, resource needs, and research priorities for communities where IBD is rising.
The study links NAD+ precursor (NMN) supplementation to changes in TGF-β–associated gene programs, intestinal immune signatures, and the gut microbiome in mouse colitis models — pathways relevant to fibrosis and...
