(Bull.: Fr.) P. Karst. spore powder (IHS) contains polyphenols and triterpenoids with pharmacological effects. Here, we analyzed its composition, and we investigated the effects of IHS on colorectal cancer (CRC) in B6/JGpt-/Gpt () mice and its potential mechanisms by analyzing gut microbiota and serum metabolomics. The enzyme-linked immunosorbent assays and Western blotting were used to confirm the changes in the cytokine and protein levels associated with IHS administration. The IHS affected the abundance of gut microbiota and the level of -arginine (-Arg). Furthermore, the IHS influenced T cells in mice by increasing the interleukin (IL)-2 and decreasing the IL-5, -6, and -10 levels, thus suppressing tumor development. Overall, IHS showed anti-CRC properties in mice by affecting the gut microbiota and serum metabolites, which in turn affected the Janus kinase (JAK)/signal transducer and activator of transcription (STAT) signaling, and regulated the abundance of CD8 T cells. These results provide experimental support for the potential future treatment of CRC with IHS.

Hypertension, commonly known as high blood pressure, is a significant health issue that increases the risk of cardiovascular diseases, stroke, and renal failure. This condition broadly encompasses both primary and secondary forms. Despite extensive research, the underlying mechanisms of systemic arterial hypertension-particularly primary hypertension, which has no identifiable cause and is affected by genetic and lifestyle agents-remain complex and not fully understood.

The gut microbiome, which is composed of bacteria, viruses, and fungi, and is involved in multiple essential physiological processes, changes measurably as a person ages, and can be associated with negative health outcomes. Microbiome transplants have been proposed as a method to improve gut function and reduce or reverse multiple disorders, including age-related diseases. Here, we take advantage of the laboratory model organism, Drosophila melanogaster, to test the effects of transplanting the microbiome of a young fly into middle-aged flies, across multiple genetic backgrounds and both sexes, to test whether age-related lifespan could be increased, and late-life physical health declines mitigated.

The effects of wheat and oat dietary fiber (DF) alone or combined on T2DM remain unclear. In this research, / diabetic mice were fed with diets containing 10% insoluble wheat dietary fiber (WDF), 10% insoluble oat dietary fiber (ODF), and 10% WODF (mixture of WDF and ODF, WDF : ODF = 1 : 1) for 8 weeks. The results showed that WDF, ODF, and WODF all reduced the body weight and fasting blood glucose (FBG) and improved oral glucose tolerance in / mice.
