Butyrate inhibits the proliferation of cancer cells, but the early molecular events initiated by butyrate have not been fully identified. Herein, butyrate is shown to affect the growth arrest and DNA damage-inducible gene 153 (GADD153) in HCT-116 human colon adenocarcinoma cells. Despite absence of any detectable cellular DNA damage, the expression of GADD153 was upregulated before several feat...
Worker yellowjackets (Hymenoptera: Vespidae) were captured in traps baited with combinations of an aqueous solution of acetic acid and polyethylene caps loaded with either butyl butyrate, heptyl butyrate, or isobutanol. Vespula germanica (F.) were captured in large numbers in traps baited with acetic acid and isobutanol or acetic acid and butyl butyrate. Vespula pensylvanica (Saussure) were cap...
Butyrate induces cytodifferentiation in many tumor cells of different origin, suggesting that an as yet unidentified common mechanism inherent to malignant cells is the target of butyrate action. This study determined the role of different mitogen-activated protein (MAP) kinase signal transduction pathways in butyrate-induced erythroid differentiation of K562 human leukemia cells. Using a panel...
Butyrate, a short-chain fatty acid fiber fermentation product, induces colonocyte apoptosis in part via a Fas-mediated (extrinsic) pathway. In previous studies, we demonstrated that docosahexaenoic acid (DHA, 22:6(Delta4,7,10,13,16,19)) enhances the effect of butyrate by increasing mitochondrial lipid oxidation and mitochondrial Ca(2+)-dependent apoptosis in the colon. In this study, we further...
We have found that butyrate selectively inhibits hormonal induction of a few specific proteins and messenger RNAs in hepatoma cells. The fatty acid salt reversibly abolishes induction of tyrosine aminotransferase by dexamethasone and dibutyryl cyclic AMP in HTC cells by inhibiting the production of tyrosine aminotransferase messenger RNA. Half-maximal inhibition of enzyme induction occurred in ...
BACKGROUND/AIMS Impaired colonocyte metabolism of butyrate has been implicated in the aetiopathogenesis of ulcerative colitis. Colonocyte butyrate metabolism was investigated in experimental colitis in mice. METHODS Colitis was induced in Swiss outbred white mice by oral administration of 4% dextran sulphate sodium (DSS). Colonocytes isolated from colitic and normal control mice were incubate...
Nonpathogenic, resident bacteria participate in the pathogenesis of inflammation in the small intestine, but the molecular messages produced by such bacteria are unknown. Inflammatory responses involve the recruitment of specific leukocyte subsets. We, therefore, hypothesized that butyrate, a normal bacterial metabolite, may modulate chemokine secretion by epithelial cells, by amplifying their ...
The gastrointestinal (GIT) segment wherein dietary additives, such as butyrate, are released may influence their observed efficacy. Release kinetics are influenced by pH, gastric and enteric motility, retention time in the different GIT segments and enzymes concentration. Unfortunately, none of the available in vitro poultry model mimics accurately these conditions. As a consequence, a novel in...
All dietary fiber, by definition, escapes digestion in the small intestine and thus arrives relatively intact in the large intestine. Its fate in the large intestine depends upon the type of fiber and the colonic microflora. Highly fermentable fibers result in short chain fatty acids including butyrate, which is thought by some to be protective against colon cancer. However, not all studies sup...
Sarcopenia, the loss of skeletal muscle mass and function during aging, is a major contributor to disability and frailty in the elderly. Previous studies found a protective effect of reduced histone deacetylase activity in models of neurogenic muscle atrophy. Because loss of muscle mass during aging is associated with loss of motor neuron innervation, we investigated the potential for the histo...
