Summary of "Effect of raw potato starch on the gut microbiome and metabolome in mice."

The gut microbiome plays a pivotal role in human health and is affected by various factors. To investigate the association between phenotypic and microbiota-related changes in the gut and a raw starch-based diet, we fed mice with different starch substitutes (corn, wheat, rice, and potato) for 16 weeks. The potato starch-fed group showed the lowest weight gain and fat tissue accumulation of all the groups, as well as the highest insulin sensitivity. Taxonomic analysis indicated that the proportions of Akkermansia, Rikenellaceae, and Sutterella showed the greatest increase in the ceca of mice fed raw potato starch. In addition, the gut microbiota of the raw potato starch group showed the highest carbohydrate and energy metabolism of all the groups, as confirmed by cecal metabolite analysis. The raw potato starch group also produced the highest propionic acid content. Our results showed that the differences in the digestibility of each starch, differences in the phenotype in terms of digestibility, and changes in intestinal microbiota were connected, and it was confirmed that potato starch, which had the lowest digestibility, caused the greatest difference in intestinal microbe composition and metabolism.

Strains of mice arising from a parental inbred stock that was subsequently used to produce substrains of knockout and other mutant mice with targeted mutations.

An effect usually, but not necessarily, beneficial that is attributable to an expectation that the regimen will have an effect, i.e., the effect is due to the power of suggestion.

Mice homozygous for the mutant autosomal recessive gene "scid" which is located on the centromeric end of chromosome 16. These mice lack mature, functional lymphocytes and are thus highly susceptible to lethal opportunistic infections if not chronically treated with antibiotics. The lack of B- and T-cell immunity resembles severe combined immunodeficiency (SCID) syndrome in human infants. SCID mice are useful as animal models since they are receptive to implantation of a human immune system producing SCID-human (SCID-hu) hematochimeric mice.

A strain of mice widely studied as a model for cystic fibrosis. These mice are generated from embryonic stem cells in which the CFTR (cystic fibrosis transmembrane conductance regulator) gene is inactivated by gene targeting. As a result, all mice have one copy of this altered gene in all their tissues. Mice homozygous for the disrupted gene exhibit many features common to young cystic fibrosis patients, including failure to thrive, meconium ileus, and alteration of mucous and serous glands.
