we demonstrate that administration of IPA modulates the microbiota composition in the gut and inhibits microbial dysbiosis in rats fed a high-fat diet. IPA induces the expression of tight junction proteins, such as ZO-1 and Occludin, and maintains intestinal epithelium homeostasis, leading to a reduction in plasma endotoxin levels.

Study, found that the stimulation of alpha7 nicotinic acetylcholine receptor but not alpha4beta2 nicotinic acetylcholine receptor decreased sodium-fluorescein permeability and increased cell transendothelial electrical resistance in rat brain endothelial cells (RBEC) monolayers and increased the protein levels of claudin-5 and occludin in RBECs.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
