High mobility group box 1 protein (HMGB1) has an important role in myocardial ischemia/reperfusion (I/R) injury. Sodium butyrate, an inhibitor of histone deacetylase, has been shown to inhibit HMGB1 expression. In the present study, the effect of sodium butyrate on myocardial I/R injury in rats was investigated. Anesthetized male rats were intraperitoneally administered sodium butyrate (100 or ...
Whether dietary fi ber intake reduces colorectal cancer risk remains controversial, possibly because epidemiologic studies have not controlled for gut microbiota composition. Bacteria in the colon convert fi ber into metabolites such as butyrate, which serves as the primary energy source for normal colonocytes but also inhibits histone deacetylases (HDAC) to epigenetically regulate gene express...
Butyrate enemas upregulate Muc genes expression but decrease adherent mucus thickness in mice colon.
Colonic mucosal protection is provided by the mucus gel, mainly composed of mucins. Several factors can modulate the formation and the secretion of mucins, and among them butyrate, an end-product of carbohydrate fermentation. However, the specific effect of butyrate on the various colonic mucins, and the consequences in terms of the mucus layer thickness are not known. Our aim was to determine ...
wnloaded short-chain fatty acid sodium butyrate (NaB), produced in the colonic lumen, induces cell cycle differentiation, and/or apoptosis in colorectal carcinoma cells in vitro, establishing a potential role aB in colon cancer prevention. We have previously shown that butyrate decreases cyclin D1 and expression, each essential for intestinal tumor development, by transcriptional attenuation. H...
There is great interest in utilizing butyrate as a chemopreventive agent for colon tumorigenesis because of its ability to promote apoptosis in colon tumor cell lines. Because CD95 (APO-1/Fas) transduces signals resulting in apoptosis, we tested the hypothesis that butyrate-dependent colonocyte apoptosis is mediated by this death receptor. Butyrate (1 mM) exposure for 24 h upregulated expressio...
Mutations in the WNT/beta-catenin pathway are responsible for initiating the majority of colorectal cancers (CRCs). We have previously shown that hyperactivation of this signaling by histone deacetylase inhibitors (HDACis) such as butyrate, a fermentation product of dietary fiber, promotes CRC cell apoptosis. The extent of association between beta-catenin and the transcriptional coactivator CRE...
Animal studies show that increasing large bowel butyrate concentration through ingestion of butyrylated or resistant starches opposes carcinogen-induced tumorigenesis, which is consistent with population data linking greater fiber consumption with lowered colorectal cancer (CRC) risk. Butyrate has been shown to regulate the apoptotic response to DNA damage. This study examined the impact of inc...
Sodium butyrate and its derivatives are useful therapeutic agents for the treatment of genetic diseases including urea cycle disorders, sickle cell disease, thalassemias, and possibly cystic fibrosis (CF). Butyrate partially restores cAMP-activated Cl- secretion in CF epithelial cells by stimulating ΔF508 cystic fibrosis transmembrane conductance regulator (ΔF508-CFTR) gene expression and incre...
background: human β-like globin genes regulaon during development from embyonic to adult stage results in generaon of different types of hemoglobin with different funcons. as β-thalassemia and sickle cell disease are disorders of β-globin chain, epigenec drugs such as thalidomide and sodium butyrate which can induce γ-globin gene are considered as a novel therapeuc approach. drugs effecve...
In the mammalian intestine, crypts of Leiberkühn house intestinal epithelial stem/progenitor cells at their base. The mammalian intestine also harbors a diverse array of microbial metabolite compounds that potentially modulate stem/progenitor cell activity. Unbiased screening identified butyrate, a prominent bacterial metabolite, as a potent inhibitor of intestinal stem/progenitor proliferation...
