Purpose Butyrate, a short-chain fatty acid derived from dietary fiber, inhibits proliferation and induces cell death in colorectal cancer cells. However, clinical trials have shown mixed results regarding the anti-tumor activities of butyrate. We have previously shown that sodium butyrate increases endoplasmic reticulum stress by altering intracellular calcium levels, a well-known autophagy trigger. Here, we investigated whether sodium butyrate-induced endoplasmic reticulum stress mediated autophagy, and whether there was crosstalk between autophagy and the sodium butyrate-induced apoptotic response in human colorectal cancer cells. Methods Human colorectal cancer cell lines (HCT-116 and HT-29) were treated with sodium butyrate at concentrations ranging from 0.5-5mM. Cell proliferation was assessed using MTT tetrazolium salt formation. Autophagy induction was confirmed through a combination of Western blotting for associated proteins, acridine orange staining for acidic vesicles, detection of

PROTOCOL OUTLINE: This is a randomized, multicenter study. Patients are randomized to one of two treatment arms. Arm I: Patients receive arginine butyrate IV over 6-9 hours at night 5 days a week for 12 weeks, plus concurrent standard local therapy consisting of cleaning, saline irrigation, and dressing changes as prescribed by each patients physician. Patients who experience progressive healing receive arginine butyrate 3-4 times a week. Arginine butyrate treatment may be discontinued and reinstated following a single 2 week medical complication.. Arm II: Patients receive standard local therapy alone for 12 weeks. Patients randomized to arm II may cross over to receive arginine butyrate if no or less than 25% healing is observed after 12 weeks.. Patients whose ulcers have closed by at least 15% per cycle may receive 2 additional 8-week cycles of arginine butyrate therapy and are followed for 2 months after healing is completed. ...

As the colonic epithelium is physiologically exposed to butyrate and to activators of protein kinase C, we examined the effect of the protein kinase C signalling pathway on butyrate-induced expression of markers of differentiation. Activators and inhibitors of protein kinase C were used in combination with butyrate and effects on the expression of markers of differentiation examined in colon cancer cell lines. When the protein kinase C activator phorbol myristate acetate (100 nM) was added for 24 h prior to the addition of 2 mM butyrate, there was a synergistic increase in alkaline phosphatase activity (154 ± 11% above that for butyrate alone, P = 0.003) in a concentration- and time-dependent manner. Butyrate-induced expression of carcinoembryonic antigen and interleukin-8, dome formation and cell turnover were also markedly augmented by pre-treatment with phorbol myristate acetate. A similar effect was observed with propionate or acetate (but not other differentiating agents), when phorbol ...

The purpose of our study was to (I) assess the relationship between apoptosis and enterocyte differentiation and (2) determine whether the cell-cycle inhibitors, p21(Wafl/cip1) and p27(Kip1), or the apoptosis inhibitors, Bcl-2 and Bcl-X(L), may be involved. Methods. Gut-derived Caco-2 cells were treated with sodium butyrate. Apoptosis was assessed by Hoechst stain, DNA laddering, and annexin V assay; differentiation was determined by alkaline phosphatase and sucrase activity. RNA and protein ...

We have reported recently that sodium butyrate suppressed IFN-γ, but not the LPS-mediated induction of nitric oxide and TNF-α in microglia via the specific inhibition of NF-κB. In order to further determine the upstream signaling mechanism involved in the IFN-γ-specific down-regulation of iNOS by sodium butyrate in microglia, this study investigated the effect of sodium butyrate on the MAP kinase activities. Sodium butyrate significantly repressed the phosphorylation of ERK induced by IFN-γ, but had little effect on that induced by LPS. This suggests that sodium butyrate suppresses the IFN-γ-induced iNOS expression by inhibiting the ERK to NF-κB pathway. In addition, it was found that sodium butyrate suppressed the IFN-γ-induced interferon regulatory factor 1 (IRF-1) expression via the inhibition of ERK. Therefore, the ERK signaling pathway appears to play a key role in the sodium butyrate-mediated down-regulation of iNOS in the IFN-γ-stimulated microglia. © 2005 Elsevier B.V. All ...

Butyrates are important as food for cells lining the mammalian colon (colonocytes). Without butyrates for energy, colon cells undergo autophagy (self digestion) and die.[1] Short-chain fatty acids (SCFAs), which include butyrate, are produced by beneficial colonic bacteria (probiotics) that feed on, or ferment prebiotics, which are plant products that contain adequate amounts of dietary fiber. These SCFAs benefit the colonocytes (cells of the colon) by increasing energy production and cell proliferation, and may protect against colon cancer.[2]. Butyrate is a major metabolite in colonic lumen arising from bacterial fermentation of dietary fiber and has been shown to be a critical mediator of the colonic inflammatory response. In fact, butyrate is responsible for about 70% of energy from the colonocytes, being a critical SCFA in the colon homeostasis[3]. Butyrate possesses both preventive and therapeutic potential to counteract inflammation-mediated ulcerative colitis (UC) and colorectal cancer. ...

Of this time point, samples were analyzed in microarray experiments. A significance test with FDR control (α=0.05) was carried out for the four technical replicates (including two dye-swaps) of the microarray. For analysis, the following filtering settings were chosen to identify differentially expressed genes: adjusted p-value ≤ 0.05, log-ratio , -1 or , 1 (equals fold change , -2 or , 2) and log-intensity ≥ 6 (equals ≥ 64 raw intensity). From a total of 1461 genes found to be differentially expressed under NaBu treatment, 771 genes were upregulated and 690 genes were downregulated (derived from EC numbers in KEGG pathways, Figure 1B). Many differentially expressed genes from pathways involved in carbohydrate, lipid, amino acid and glycan metabolism are upregulated which is most likely linked to higher productivity. A large portion of genes from pathways associated with cell growth and death are downregulated and most of these genes originate from cell cycle processes. This correlates ...

The microbiota of the gastrointestinal tract of humans has been studied extensively because of the role played by gut bacteria both in disease and in the maintenance of gut health (7, 17, 27). One important activity of the large intestinal microbiota is to break down substrates, such as resistant starch and plant cell wall polysaccharides. The main fermentation products are the short-chain fatty acids acetate, propionate, and butyrate. Of these, butyrate is known to play an important role in the metabolic welfare of colonocytes (19, 20) and is also implicated in providing protection against cancer and ulcerative colitis (3-5). Despite this prominent role, the taxonomy, population structure, and dynamics of predominant butyrate-producing bacteria in the human intestinal tract are poorly understood.. There is no simple way to selectively isolate butyrate-producing bacteria, and the majority of those recovered from nonselective isolation have proved to be highly oxygen sensitive (2). The purpose of ...

Butyrate, an intestinal microbiota metabolite of dietary fiber, exhibits chemoprevention effects on colon cancer development. However, the mechanistic action of butyrate remains to be determined. We hypothesize that butyrate inhibits cancerous cell proliferation but to a lesser extent in noncancerous cells through regulating apoptosis and cellular-signaling pathways. We tested this hypothesis by exposing cancerous HCT116 or non-cancerous NCM460 colon cells to physiologically relevant doses of butyrate. Cellular responses to butyrate were characterized by Western analysis, fluorescent microscopy, acetylation, and DNA fragmentation analyses. Butyrate inhibited cell proliferation, and led to an induction of apoptosis, genomic DNA fragmentation in HCT116 cells, but to a lesser extent in NCM460 cells. Although butyrate increased H3 histone deacetylation and p21 tumor suppressor expression in both cell types, p21 protein level was greater with intense expression around the nuclei in HCT116 cells when compared

DESCRIPTION (provided by applicant): The short chain fatty acid butyrate is a physiological regulator of colon epithelial cell maturation (cell cycle arrest, lineage specific differentiation and apoptosis). While there is considerable interest in the role of butyrate as an inhibitor of histone deacetylase (HDAC) activity, we have demonstrated that other mechanisms triggered by butyrate must play essential roles in the stimulation and integration of the overall complex affects on colon cell maturation. The goal of this application is to dissect the contribution of two fundamental epigenetic mechanisms stimulated by butyrate: alteration of expression of microRNAs, and transcriptional attenuation. We will first address these issues using novel gene expression arrays that we have designed and fabricated to interrogate altered profiles of microRNA expression, and genome wide alterations in transcriptional attenuation, in response to butyrate. As regards microRNAs, our preliminary data demonstrate ...

We have demonstrated for the first time that butyrate inhibits inflammatory responses in CD by inhibition of NFκB activation in immune cells.. High levels of circulating and mucosal proinflammatory cytokines are a characteristic feature of CD.1 2 We confirmed that intestinal biopsies as well as isolated LPMC obtained from inflamed mucosa of CD patients secrete significantly more IL-1β, IL-6, and TNF than normal controls.7 34 35 Our main finding was that butyrate had a dose dependent effect in decreasing TNF secretion in both inflamed and non-inflamed tissues. Interestingly, with 10 mM butyrate, TNF levels returned to control values. Similar results were observed for IL-6 and, although less consistently, for IL-1β (data not shown). Although intestinal epithelial cells can secrete proinflammatory cytokines, we focussed on immune cells which are the main effectors of the inflammatory response in CD. We then determined that butyrate decreased proinflammatory cytokine production by downregulating ...

Metabolic activities of butyric acid were examined in this study in diet-induced obese mice. The most important observation is that butyrate supplementation at 5% wt/wt in high-fat diet prevented development of dietary obesity and insulin resistance. It also reduced obesity and insulin resistance in obese mice. In butyrate-treated mice, the plasma butyrate concentration was increased, and blood lipids (triglycerides, cholesterol, and total fatty acids) were decreased (Fig. 6H-I and Supplement 1). The change in insulin sensitivity may be a consequence of a reduction in adiposity in our model. The increase in energy expenditure and fatty acid oxidation may be responsible for the antiobesity effect of butyrate. Butyrate supplementation did not reduce food intake, fat absorption, or locomotor activity, suggesting that there was no toxicity from butyrate. Butyrate was tested at 5 and 2.5% wt/wt in the high-fat diet in this study. At the lower (2.5% wt/wt) dosage, similar metabolic activity was ...

Butyrate is the preferred energy source for colonocytes and has an important role in gut health; in contrast, accumulation of high concentrations of lactate is detrimental to gut health. The major butyrate-producing bacterial species in the human colon belong to the Firmicutes. Eubacterium hallii and a new species, Anaerostipes coli SS2/1, members of clostridial cluster XIVa, are able to utilize lactate and acetate via the butyryl CoA : acetate CoA transferase route, the main metabolic pathway for butyrate synthesis in the human colon. Here we provide a mathematical model to analyse the production of butyrate by lactate-utilizing bacteria from the human colon. The model is an aggregated representation of the fermentation pathway. The parameters of the model were estimated using total least squares and maximum likelihood, based on in vitro experimental data with E. hallii L2-7 and A. coli SS2/1. The findings of the mathematical model adequately match those from the bacterial batch culture experiments.

By Sue Cummings. Ive been talking with a lot of customers lately who, like me, suffer from irritable bowel syndrome, hypothyroid and multiple food sensitivities - all signs of a leaky gut. Ive been working with a whole food diet, lots of fermented foods, fiber and probiotic supplements, but the healing process can be slow. Frustrated, I kept looking for answers and I think Ive found a good one. Its called butyrate.. Butyrate is a short chain fatty acid with some amazing research results, though many of the studies are small or on mice. Nonetheless, results show that butyrate can reduce pain and other symptoms of irritable bowel, improve the intestinal barrier (thereby reducing leaky gut), reduce inflammation in the bowel, improve Crohns disease (a form of inflammatory bowel disease), and may help with weight loss and insulin resistance!. With a list like that how could I not try it? So Ive been experimenting for a couple of months now and Im really pleased with my results. In general my ...

Anti-microbial signaling pathways are normally triggered by innate immune receptors when detecting pathogenic microbes to provide protective immunity. Here we show that the inflammasome sensor Nlrp1 aggravates DSS-induced experimental mouse colitis by limiting beneficial, butyrate-producing Clostridiales in the gut. The colitis-protective effects of Nlrp1 deficiency are thus reversed by vancomycin treatment, but recapitulated with butyrate supplementation in wild-type mice. Moreover, an activating mutation in Nlrp1a increases IL-18 and IFNγ production, and decreases colonic butyrate to exacerbate colitis. We also show that, in patients with ulcerative colitis, increased NLRP1 in inflamed regions of the colon is associated with increased IFN-γ. In this context, NLRP1, IL-18 or IFN-γ expression negatively correlates with the abundance of Clostridiales in human rectal mucosal biopsies. Our data identify the NLRP1 inflammasome to be a key negative regulator of protective, butyrate-producing commensals,

We have to address the issue that there are bad bacteria all around as well. The more they proliferate, the sicker we become. The challenge we face it to consistently keep lots of the good bacteria around but at the same time get rid of the bad or pathogenic bacteria. The way our good flora tell our immune system that theyre helpful and beneficial bacteria, and not bad bacteria, is by butyrate signals. Clinical rsearch has shown us how butyrate is able to suppresses inflammatory reaction and how butyrate instructs our immune system to calms down.. When butyrate levels are low, our immune system doesnt know this and is therefore unable to stop their attack on bacteria.. When we dont fuel the growth of good bacteria with enough fiber, we dont produce enough butyrate. Hypothetically, we could have lots of good bacteria, however, if we fail to feed them with fiber, they dont make butyrate.. Unfortunately when our body senses low levels of butyrate, it mistakenly thinks that our gut is filled ...

Whether dietary fiber protects against colorectal cancer is controversial because of conflicting results from human epidemiologic studies. However, these studies and mouse models of colorectal cancer have not controlled the composition of gut microbiota, which ferment fiber into short-chain fatty acids such as butyrate. Butyrate is noteworthy because it has energetic and epigenetic functions in colonocytes and tumor-suppressive properties in colorectal cancer cell lines. We used gnotobiotic mouse models colonized with wild-type or mutant strains of a butyrate-producing bacterium to demonstrate that fiber does have a potent tumor-suppressive effect but in a microbiota- and butyrate-dependent manner. Furthermore, due to the Warburg effect, butyrate was metabolized less in tumors where it accumulated and functioned as a histone deacetylase (HDAC) inhibitor to stimulate histone acetylation and affect apoptosis and cell proliferation. To support the relevance of this mechanism in human cancer, we ...

In the present study, we used a polyphasic approach to study the effects of four purified NSP fractions of low and high viscosity and fermentability on the taxonomic composition of the ileal and fecal microbiota and, at a metabolic level, on butyrate-producing bacteria and E. coli virulence factors, using TRFLP and qPCR. Because purified NSP fractions may affect the bacterial community structure in a different way when added to a cereal-based diet due to the NSP in the grain matrix (36), a semipurified diet was employed in the present experiment.. The NSP fractions differently affected the small intestinal digestion and markedly changed the availability of fermentable substrate in the large intestine. However, there was no evidence that the shared functional properties affected digestive processes and endogenous nitrogen losses (44) consistently among the NSP fractions, suggesting that the specific chemical structures of the NSP are as relevant as shared rheological properties (8, 48). ...

Adult White Leghorn chickens were rendered anemic by injection with 1-acetyl-2-phenylhydrazine and then treated with parenteral 5-azacytidine, and levels of embryonic globin RNA in circulating reticulocytes were measured. A very small but detectable amount of correctly initiated embryonic p-type globin RNA was detected in reticulocytes from birds treated with 5-azacytidine, while none was detected in reticulocytes from those receiving only phenylhydrazine or phenylhydrazine plus 1-beta-D-arabinofuranosylcytosine (cytosine arabinonucleoside). An attempt to increase embryonic globin RNA induction by treatment with parenteral sodium butyrate after 7 days of 5-azacytidine administration resulted in a 5- to 10-fold increase in the level of embryonic globin RNA. However, sodium butyrate did not induce embryonic gene expression when given alone or after treatment with cytosine arabinonucleoside. Sodium butyrate treatment also caused a DNase I-hypersensitive site to be exposed at the 5 end of the ...

No effective treatment of this disorder is presently available. Studies of the correlation between disease severity and the amount of survival motor neuron (SMN) protein have shown an inverse relationship. We report that sodium butyrate effectively increases the amount of exon 7-containing SMN protein in SMA lymphoid cell lines by changing the alternative splicing pattern of exon 7 in the SMN2 gene. In vivo, sodium butyrate treatment of SMA-like mice resulted in increased expression of SMN protein in motor neurons of the spinal cord and resulted in significant improvement ...

Dental stem cells, especially dental follicle cells (DFCs) as precursor cells for the periodontium have interesting prospects for regenerative dentistry. During periodontitis, butyrate as a bacterial metabolite and inflammatory agent is often found in millimolar concentrations in periodontal pockets. This study evaluates the effects of butyrate on the proliferation and osteogenic differentiation of DFCs. We assessed cell viability/proliferation (BCA assay) and osteogenic differentiation (ALP activity, alizarin staining and RT PCR) of DFCs in vitro after butyrate supplementation. Butyrate concentrations of 20 mM or higher are toxic for DFCs. At a non-toxic concentration, butyrate promotes the expression of alkaline phosphatase and collagen type-1 but inhibits the formation of calcified nodules and the induction of RUNX2 and osteocalcin under osteogenic differentiation conditions. In conclusion, DFCs are resistant to physiological high concentrations of butyrate. Butyrate facilitates the ...

In the present work, we studied the molecular mechanisms by which sodium butyrate sensitizes cancer cells towards cisplatin. HeLa cells were treated with 5 mM butyrate, with 8 μM cis-diaminedichloroplatinum II (cisplatin), or with both. Cells treated with both agents showed approximately two-fold increase of the mortality rate in comparison with cells treated with cisplatin only. Accordingly, the life span of albino mice transfected with Ehrlich ascites tumor was prolonged almost two-fold by treatment with cisplatin and butyrate in comparison with cisplatin alone. This showed that the observed synergism of cisplatin and butyrate was not limited to specific cell lines or in vitro protocols, but was also expressed in vivo during the process of tumor development. DNA labeling and fluorescence activated cell sorting experiments showed that cisplatin treatment inhibited DNA synthesis and arrested HeLa cells at the G1/S transition and early S phase of the cell cycle.

Congenital chloride diarrhea (CLD) is an autosomal recessive disorder characterized by life-long, severe diarrhea with intestinal Cl- malabsorption. It results from a reduced activity of the down regulated in adenoma exchanger (DRA), due to mutations in the solute carrier family 26, member 3 (SLC26A3) gene. Currently available therapies are not able to limit the severity of diarrhea in CLD. Conflicting results have been reported on the therapeutic efficacy of oral butyrate. We investigated the effect of oral butyrate (100 mg/kg/day) in seven CLD children with different SLC26A3 genotypes. Nasal epithelial cells were obtained to assess the effect of butyrate on the expression of the two main Cl- transporters: DRA and putative anion transporter-1 (PAT-1). A variable clinical response to butyrate was observed regarding the stool pattern and fecal ion loss. The best response was observed in subjects with missense and deletion mutations. Variable response to butyrate was also observed on SLC26A3 (DRA) and

The use of short chain fatty acids to modulate gastrointestinal inflammatory conditions such as ulcerative colitis has produced encouraging results either in animal models or also in clinical trials. Identifying the key cellular and molecular targets of this activity will contribute to establish the appropriate combinations/targeting strategies to maximize the efficacy of anti-inflammatory interventions. In the present work, we evaluated in vitro the interaction of lactate, acetate, propionate and butyrate on cells relevant for innate immune response of the gastrointestinal tract. All molecules tested regulate the production of proinflammatory cytokines by TLR-4 and TLR-5 activated intestinal epithelial cells in a dose response manner.

FIG. 1. Energy metabolism in response to sodium butyrate. Butyrate increased energy expenditure in C57BL/B6 mice. Energy expenditure was examined using the metabolic chamber at the 1st week and the 10th week on high-fat diet (16 weeks in age). In this study, sodium butyrate was used at 5% wt/wt in high-fat diet. A: Food intake. Food intake was monitored daily for 5 days at each time point. Average daily food intake (g) was converted into kilocalories and normalized with body weight (kg) and 24 h. B: Energy expenditure measured as kilocalories per kilogram lean mass per hour. C: Oxygen consumption measured as milliliters volume oxygen per kilogram lean mass per hour. D: Substrate utilization. This is expressed by respiratory exchange ratio (RER), which is the volume ratio of oxygen consumed versus CO2 exhaled. E: Body weight (BW). F: Body fat content in percentage of body weight. This was determined by nuclear magnetic resonance. G: Body muscle content in percentage of body weight. H: Lipid in ...

Effect of Butyric Acid on Performance, Gastrointestinal Tract Health and Carcass Characteristics in Broiler Chickens Butyric Acid;Performance;GI Tract Health;Carcass Characteristics;Broiler Chickens; An experiment was conducted to study the effect of graded levels of butyric acid (butyrate) on performance, gastrointestinal tract health and carcass characteristics in young broiler chickens. Control starter (0-3 wk) and finisher (4-5 wk) diets were formulated to contain 2,900 kcal ME/kg and 22% CP, and 3,000 kcal ME/kg and 20% CP, respectively. Subsequently, four other experimental diets were formulated to contain 0.05% antibiotic (furazolidone) or 0.2, 0.4 and 0.6% butyric acid. Each diet was fed at random to 8 replicates of 6 chicks each throughout the experimental period (0-5 wk). The results showed that 0.4% butyrate in the diet was similar to antibiotic in maintaining body weight gain and reducing E. coli numbers but superior for feed conversion ratio. No added advantage on these parameters was

BACKGROUND: The predominant colonic short chain fatty acids, acetate, propionate, and butyrate, are oxidised into CO2 in colonocytes from rat and humans in the preferred order of butyrate (C4) , propionate (C3) , acetate (C2)- hence butyrate is considered to be the principal oxidative substrate for colonocytes. AIMS: To compare colonocyte oxidation of valerate (C5), hexanoate (C6), and octanoate (C8) with that of butyrate. METHODS: Isolated rat colonocytes were incubated in the presence of a concentration range of 1-14C labelled C2-C8 fatty acids. Oxidation rates were obtained by quantifying the production of 14CO2, and Vmax (maximum velocity) and K(m) (Michaelis-Menten constant) were calculated by computer fitting of the data to a Michaelis-Menten plot. RESULTS: The K(m) value of acetate (0.56 (SEM 0.02) mmol/l) was about fourfold higher than the K(m) of butyrate (0.13 (0.01) mmol/l), whereas the K(m) values of valerate (0.19 (0.01) mmol/l), hexanoate (0.19 (0.01) mmol/l), and octanoate (0.16 ...

Despite questions regarding the role of microbiota in regulation of host immune responses within the intestines, evidence suggests that in the context of disease and autoimmunity bacterial metabolites might impact the systemic immune response. Otherwise indigestible carbohydrates are metabolized into short-chain fatty acids (SCFAs) by gut bacteria. SCFAs have been shown to inhibit intestinal inflammation in experimental colitis through regulation of mucosal T cells and macrophages. Recently, neutrophils have been shown to regulate intestinal homeostasis and the pathogenesis of IBD, however, how SCFAs may regulate neutrophil function is unclear. In this study, we demonstrate that SCFA differentially regulate neutrophil cytokine production. Of the three major SCFAs butyrate, acetate, and propionate, only butyrate down-regulated neutrophil IL-10 production. We further showed that butyrate-inhibition of neutrophil IL-10 is independent of GPR43, in that butyrate also inhibited IL-10 production in ...

We take a look at how gut microbes communicate with our bodies, as well as short chain fatty acids (SCFA) and how they impact the intestine. Learn more.

One of the ways your gut microbes contribute to overall health is through byproducts created by their fermentation of specific fibers in the GI tract. These fibers, known as prebiotics, resist decomposition and absorption in the upper GI tract but are utilized by bacteria in the colon for energy. These colonic bacteria use specific enzymes to break these fibers down into short chain fatty acids (SCFA), among other products. Acetate, propionate and butyrate are the predominate SFCAs created. These fatty acids provide energy to bacteria and also appear to also benefit their human host. (thats us!) Short chain fatty acids lower the pH of the colon, thus inhibiting the growth of pathogenic bacterial species and promoting thriving populations of bifidiobacteria and lactobacilli species, also known as the good guys (Slavin, 2013). SCFA also appear to play a role in the association between fiber intake and reduced risk of developing gastrointestinal disorders, cancer, as well as cardiovascular ...

Transcriptional factor NF-κB was first found to be involved in activating genes involved in immune and inflammatory responses. Subsequently NF-κB was found to be important for regulating the expression of genes involved in cell proliferation and survival. Consistent with its role in regulating cell proliferation, we found that NF-κB regulates expression of the mouse TERT gene (telomerase reverse transcriptase). NF-κB-dependent TERT expression might serve to maintain telomere length in the conditions like inflammation and infection. ^ Colon epithelial cells are an interesting system to study NF-κB regulation, since they can be subjected to multiple inflammatory and growth regulatory signals. Published data demonstrates that the luminal provision of butyrate can improve symptoms of inflammatory bowel diseases. We found that colon epithelial cells alter their NF-κB activity in presence of butyrate. Our data showed that butyrate blocks translocation of p65 subunit into nucleus following TNF-α

To test the mechanism for inactivation of the p57 gene in gastric cancer cells, eight gastric cancer cell lines were treated with either the HDAC inhibitors, n-butyric acid or TSA, or the demethylation agent, 5-aza-2′-deoxycytidine. RNA was isolated from the cells and RNA expression was analyzed by RT-PCR. RNA expression of the p57 gene was activated by HDAC inhibitors, either n-butyric acid or TSA in all of the eight gastric cancer cells. SNU1 was an exception in that TSA activated the p57 gene, but n-butyric acid did not. An appropriate explanation for this is not currently available except that it may be a clonal variation. Treatment with 5-aza-2′-deoxycytidine also activated the p57 gene in five of eight gastric cancer cell lines (Fig. 2⇓ ). The result suggests that the p57 gene seems to be inactivated by the formation of an inactive chromatin complex containing HDAC. Methylation of the promoter of the p57 gene is also involved in inactivation of the p57 gene. The presence of ...

The effect of supplementing the standard piglet diet containing sodium butyrate with glutamine and/or glucose on the structure of the piglet digestive tract and the small intestine epithelium, acidity and volatile fatty acid content of its digesta was investigated. The free amino acids level, insulin and insulin-like growth factor-1 (IGF-1) concentration in the blood were also analysed. The experiment was performed on 156 piglets (15 litters) allocated to 5 experimental groups, 3 litters in each. Group I (C, negative control) received a basal mixture with no supplement. Group II (SB, positive control) was fed the same basal diet containing additionally 3 g of sodium butyrate per kg. Group III and IV, besides sodium butyrate, received additionally 10 g of glutamine (GT) or glucose (GC), respectively. The last group V received all these supplements, i.e. SB+GT+GC (3, 10, 10 g per kg, respectively). At 60 days of age, the piglets (6 animals from each group) were slaughtered and their intestines ...

Butyrate and propionate are two important short-chain fatty acids (SCFAs) produced in the human gut. They have been shown to have significant immune system effects in the intestinal mucosa, by inducing the differentiation of T-regulatory cells via inhibition of histone deacetylase (HDAC). This enzyme keeps chromatin from unwinding and, therefore, inhibits gene transcription ...

Adding the right prebiotic to the diets of pediatric patients with intestinal failure could replace intravenous feeding, says a new University of Illinois study.. When we fed the carbohydrate fructooligosacharide (FOS) as a prebiotic, the gut grew and increased in function, said Kelly A. Tappenden, a U of I professor of nutrition and gastrointestinal physiology. The study showed that using the correct pre- and probiotic in combination could enhance these results even more.. When FOS enters the intestines, bacteria convert it into butyrate, a short-chain fatty acid that increases the size of the gut and its ability to digest and absorb nutrients, she said.. But todays IV solutions dont contain butyrate and adding it would entail drug development trials and regulatory red tape. She wanted to see if adding this carbohydrate to the diet while continuing to provide most nutrients intravenously would cause the gut to start producing butyrate on its own. It worked.. According to Tappenden, at ...

Here we report the combined effect of butyrate, an apoptosis inducer that is produced through fermentation of fiber in the colon, and propolis, a honeybee product, on CC cells. We established that propolis increases the apoptosis of CC cells exposed to butyrate through suppression of cell survival pathways such as the AKT signaling. The programmed death of CC cells by combined exposure to butyrate and propolis is further augmented by inhibition of the JNK signaling pathway. Analyses on the contribution of the downstream targets of JNK signaling, c-JUN and JAK/STAT, to the apoptosis of butyrate/propolis-treated CC cells ascertained that JAK/STAT signaling has an anti-apoptotic role; whereas, the role of cJUN might be dependent upon regulatory cell factors ...

In the context of the obesity epidemic, dietary fibers that are found essentially in fruit and vegetables attract more and more attention, since they exert numerous metabolic benefits resulting in the moderation of body weight. Short-chain fatty acids, such as propionate and butyrate, produced through their fermentation by the intestinal microbiota, have long been thought to be the mediators of these benefits. In fact, propionate and butyrate were recently shown to activate intestinal gluconeogenesis, a function exerting metabolic benefits via its capacity of signaling to the brain by gastrointestinal nerves. Recently, succinate, the precursor of propionate in the bacterial metabolism, has also been shown to exert signaling properties, including the activation of intestinal gluconeogenesis.

n-Butyrate derivatives designed to possess G1 blocker activity both in vitro and in vivo were synthesized. The ester (MEB) and ester/amide (BEB) derivatives of butyrate were found to suppress IL-2-stimulated proliferation of Th1 cells in vitro. Unlike MEB and BEB, the amide analog of butyrate, MEBA, did not suppress Th1 cell proliferation in vitro. The lack of activity of MEBA may be related to the slower metabolic hydrolysis of the amide bond in MEBA compared with the ester bond in MEB and BEB. When tested in vivo, both MEB and BEB, but not MEBA, were shown to significantly suppress a primary antibody response to a thymus-dependent antigen. Suppression of antibody production could reflect inhibition of T and/or B cell function. However, subsequent in vivo experiments to more specifically examine the effect of MEB on T cell activity revealed that MEB induced antigen-specific unresponsiveness in CD4+ T cells. The T cell unresponsiveness induced in mice immunized with ovalbumin and treated with ...
