The intracellular transfer of information (biological activation/inhibition) through a signal pathway. In each signal transduction system, an activation/inhibition signal from a biologically active molecule (hormone, neurotransmitter) is mediated via the coupling of a receptor/enzyme to a second messenger system or to an ion channel. Signal transduction plays an important role in activating cellular functions, cell differentiation, and cell proliferation. Examples of signal transduction systems are the GAMMA-AMINOBUTYRIC ACID-postsynaptic receptor-calcium ion channel system, the receptor-mediated T-cell activation pathway, and the receptor-mediated activation of phospholipases. Those coupled to membrane depolarization or intracellular release of calcium include the receptor-mediated activation of cytotoxic functions in granulocytes and the synaptic potentiation of protein kinase activation. Some signal transduction pathways may be part of larger signal transduction pathways; for example, protein kinase activation is part of the platelet activation signal pathway.

A group of autosomal-dominant inherited diseases in which COLON CANCER arises in discrete adenomas. Unlike FAMILIAL POLYPOSIS COLI with hundreds of polyps, hereditary nonpolyposis colorectal neoplasms occur much later, in the fourth and fifth decades. HNPCC has been associated with germline mutations in mismatch repair (MMR) genes. It has been subdivided into Lynch syndrome I or site-specific colonic cancer, and LYNCH SYNDROME II which includes extracolonic cancer.

Inhibition of in vitro enteric neuronal development by endothelin-3: mediation by endothelin B receptors. (1/8609)

The terminal colon is aganglionic in mice lacking endothelin-3 or its receptor, endothelin B. To analyze the effects of endothelin-3/endothelin B on the differentiation of enteric neurons, E11-13 mouse gut was dissociated, and positive and negative immunoselection with antibodies to p75(NTR )were used to isolate neural crest- and non-crest-derived cells. mRNA encoding endothelin B was present in both the crest-and non-crest-derived cells, but that encoding preproendothelin-3 was detected only in the non-crest-derived population. The crest- and non-crest-derived cells were exposed in vitro to endothelin-3, IRL 1620 (an endothelin B agonist), and/or BQ 788 (an endothelin B antagonist). Neurons and glia developed only in cultures of crest-derived cells, and did so even when endothelin-3 was absent and BQ 788 was present. Endothelin-3 inhibited neuronal development, an effect that was mimicked by IRL 1620 and blocked by BQ 788. Endothelin-3 failed to stimulate the incorporation of [3H]thymidine or bromodeoxyuridine. Smooth muscle development in non-crest-derived cell cultures was promoted by endothelin-3 and inhibited by BQ 788. In contrast, transcription of laminin alpha1, a smooth muscle-derived promoter of neuronal development, was inhibited by endothelin-3, but promoted by BQ 788. Neurons did not develop in explants of the terminal bowel of E12 ls/ls (endothelin-3-deficient) mice, but could be induced to do so by endothelin-3 if a source of neural precursors was present. We suggest that endothelin-3/endothelin B normally prevents the premature differentiation of crest-derived precursors migrating to and within the fetal bowel, enabling the precursor population to persist long enough to finish colonizing the bowel.  (+info)

Expression of nitric oxide synthase in inflammatory bowel disease is not affected by corticosteroid treatment. (2/8609)

AIM: To examine the effect of corticosteroid treatment on the expression of inducible nitric oxide synthase (iNOS) in the colon of patients with inflammatory bowel disease. METHODS: Four groups of patients were studied: (1) ulcerative colitis treated with high dose corticosteroids (six patients, 10 blocks); (2) ulcerative colitis patients who had never received corticosteroids (10 patients, 16 blocks); (3) Crohn's disease treated with high dose corticosteroids (12 patients, 24 blocks); (4) Non-inflammatory, non-neoplastic controls (four patients, six blocks). Full thickness paraffin sections of colons removed at surgery were immunostained with an antibody raised against the C terminal end of iNOS. Sections were assessed semiquantitatively for the presence and degree of inflammation and immunoreactivity for nitric oxide synthase. RESULTS: Cases of ulcerative colitis and Crohn's disease with active inflammation showed strong staining for nitric oxide synthase. The staining was diffuse in ulcerative colitis and patchy in Crohn's disease, in accordance with the distribution of active inflammation. Staining was seen in epithelial cells and was most intense near areas of inflammation such as crypt abscesses. Non-inflamed epithelium showed no immunoreactivity. Treatment with corticosteroids made no difference to the amount of nitric oxide synthase. CONCLUSIONS: Expression of nitric oxide synthase is increased in both ulcerative colitis and Crohn's disease and appears to be unaffected by treatment with corticosteroids. Disease severity necessitated surgery in all the cases included in this study, regardless of whether or not the patients had received long term corticosteroid treatment. It seems therefore that a high level of iNOS expression and, presumably, production of nitric oxide characterise cases which are refractory to clinical treatment; this suggests that specific inhibition of the enzyme may be a useful therapeutic adjunct.  (+info)

Colon and rectal anastomoses do not require routine drainage: a systematic review and meta-analysis. (3/8609)

OBJECTIVE: Many surgeons continue to place a prophylactic drain in the pelvis after completion of a colorectal anastomosis, despite considerable evidence that this practice may not be useful. The authors conducted a systematic review and meta-analysis of randomized controlled trials to determine if placement of a drain after a colonic or rectal anastomosis can reduce the rate of complications. METHODS: A search of the Medline database of English-language articles published from 1987 to 1997 was conducted using the terms "colon," "rectum," "postoperative complications," "surgical anastomosis," and "drainage." A manual search was also conducted. Four randomized controlled trials, including a total of 414 patients, were identified that compared the routine use of drainage of colonic and/or rectal anastomoses to no drainage. Two reviewers assessed the trials independently. Trial quality was critically appraised using a previously published scale, and data on mortality, clinical and radiologic anastomotic leakage rate, wound infection rate, and major complication rate were extracted. RESULTS: The overall quality of the studies was poor. Use of a drain did not significantly affect the rate of any of the outcomes examined, although the power of this analysis to exclude any difference was low. Comparison of pooled results revealed an odds ratio for clinical leak of 1.5 favoring the control (no drain) group. Of the 20 observed leaks among all four studies that occurred in a patient with a drain in place, in only one case (5%) did pus or enteric content actually appear in the effluent of the existing drain. CONCLUSIONS: Any significant benefit of routine drainage of colon and rectal anastomoses in reducing the rate of anastomotic leakage or other surgical complications can be excluded with more confidence based on pooled data than by the individual trials alone. Additional well-designed randomized controlled trials would further reinforce this conclusion.  (+info)

Segmental colonic transit after oral 67Ga-citrate in healthy subjects and those with chronic idiopathic constipation. (4/8609)

Measurement of segmental colonic transit is important in the assessment of patients with severe constipation. 111In-diethylenetriamine pentaacetic acid (DTPA) has been established as the tracer of choice for these studies, but it is expensive and not readily available. 67Ga-citrate is an inexpensive tracer and when given orally is not absorbed from the bowel. It was compared with 111In-DTPA in colonic transit studies in nonconstipated control subjects and then in patients with idiopathic constipation. METHODS: Studies were performed after oral administration of 3 MBq (81 microCi) 67Ga-citrate or 4 MBq (108 microCi) 111In-DTPA in solution. Serial abdominal images were performed up to 96 h postinjection, and computer data were generated from geometric mean images of segmental retention of tracer, mean activity profiles and a colonic tracer half-clearance time. RESULTS: There were no differences in segmental retention of either tracer or in mean activity profiles between control subjects and constipated patients. Results in constipated subjects were significantly different from those in controls. The mean half-clearance times of tracer for control subjects were 28.8 h for 67Ga-citrate and 29.9 h for 111In-DTPA in control subjects and 75.0 h for 67Ga-citrate and 70.8 h for 111In-DTPA in constipated patients. CONCLUSION: Oral 67Ga-citrate can be used as a safe alternative to 111In-DTPA for accurate measurement of segmental colonic transit.  (+info)

Modulation of distal colonic epithelial barrier function by dietary fibre in normal rats. (5/8609)

BACKGROUND: Dietary fibre influences the turnover and differentiation of the colonic epithelium, but its effects on barrier function are unknown. AIMS: To determine whether altering the type and amount of fibre in the diet affects paracellular permeability of intestinal epithelium, and to identify the mechanisms of action. METHODS: Rats were fed isoenergetic low fibre diets with or without supplements of wheat bran (10%) or methylcellulose (10%), for four weeks. Paracellular permeability was determined by measurement of conductance and 51Cr-EDTA flux across tissue mounted in Ussing chambers. Faecal short chain fatty acid (SCFA) concentrations were assessed by gas chromatography, epithelial kinetics stathmokinetically, and mucosal brush border hydrolase activities spectrophotometrically. RESULTS: Body weight was similar across the dietary groups. Conductance and 51Cr-EDTA flux were approximately 25% higher in animals fed no fibre, compared with those fed wheat bran or methylcellulose in the distal colon, but not in the caecum or jejunum. Histologically, there was no evidence of epithelial injury or erosion associated with any diet. The fibres exerted different spectra of effects on luminal SCFA concentrations and pH, and on mucosal indexes, but both bulked the faeces, were trophic to the epithelium, and stimulated expression of a marker of epithelial differentiation. CONCLUSIONS: Both a fermentable and a non-fermentable fibre reduce paracellular permeability specifically in the distal colon, possibly by promoting epithelial cell differentiation. The mechanisms by which the two fibres exert their effects are likely to be different.  (+info)

The role of psychological and biological factors in postinfective gut dysfunction. (6/8609)

BACKGROUND: Both psychological and physiological disturbances have been implicated in the aetiopathogenesis of irritable bowel syndrome (IBS). AIMS: To investigate how the psychological factors act, and the involvement of infective and physiological factors. METHODS: Consecutive patients hospitalised for gastroenteritis reported life events for the previous 12 months, and past illness experiences on standardised questionnaires. They also completed psychometric questionnaires for anxiety, neuroticism, somatisation, and hypochondriasis. In some patients, rectal biopsy specimens were obtained during the acute illness and at three months postinfection. RESULTS: Ninety four patients completed all questionnaires: 22 patients were diagnosed with IBS after their gastroenteritis (IBS+), and 72 patients returned to normal bowel habits (IBS-). IBS+ patients reported more life events and had higher hypochondriasis scores than IBS- patients. The predictive value of the life event and hypochondriasis measures was highly significant and independent of anxiety, neuroticism, and somatisation scores, which were also elevated in IBS+ patients. Rectal biopsy specimens from 29 patients showed a chronic inflammatory response in both IBS+ and IBS- patients. Three months later, specimens from IBS+ patients continued to show increased chronic inflammatory cell counts but those from IBS- patients had returned to normal levels. IBS+ and IBS- patients exhibited rectal hypersensitivity and hyper-reactivity and rapid colonic transit compared with normal controls, but there were no significant differences between IBS+ and IBS- patients for these physiological measurements. CONCLUSION: Psychological factors most clearly predict the development of IBS symptoms after gastroenteritis but biological mechanisms also contribute towards the expression of symptoms.  (+info)

Is early post-operative treatment with 5-fluorouracil possible without affecting anastomotic strength in the intestine? (7/8609)

Early post-operative local or systemic administration of 5-fluorouracil (5-FU) is under investigation as a means to improve outcome after resection of intestinal malignancies. It is therefore quite important to delineate accurately its potentially negative effects on anastomotic repair. Five groups (n = 24) of rats underwent resection and anastomosis of both ileum and colon: a control group and four experimental groups receiving daily 5-FU, starting immediately after operation or after 1, 2 or 3 days. Within each group, the drug (or saline) was delivered either intraperitoneally (n = 12) or intravenously (n = 12). Animals were killed 7 days after operation and healing was assessed by measurement of anastomotic bursting pressure, breaking strength and hydroxyproline content. In all cases, 5-FU treatment from the day of operation or from day 1 significantly (P<0.025) and severely suppressed wound strength; concomitantly, the anastomotic hydroxyproline content was reduced. Depending on the location of the anastomosis and the route of 5-FU administration, even a period of 3 days between operation and first dosage seemed insufficient to prevent weakening of the anastomosis. The effects of intravenous administration, though qualitatively similar, were quantitatively less dramatic than those observed after intraperitoneal delivery. Post-operative treatment with 5-FU, if started within the first 3 days after operation, is detrimental to anastomotic strength and may compromise anastomotic integrity.  (+info)

Low tumour cell proliferation at the invasive margin is associated with a poor prognosis in Dukes' stage B colorectal cancers. (8/8609)

The conflicting results about the prognostic impact of tumour cell proliferation in colorectal cancer might be explained by the heterogeneity observed within these tumours. We have investigated whether a systematic spatial heterogeneity exists between different compartments, and whether the presence of such a systematic heterogeneity has any impact on survival. Fifty-six Dukes' stage B colorectal cancers were carefully morphometrically quantified with respect to the immunohistochemical expression of the proliferative marker Ki-67 at both the luminal border and the invasive margin. The proliferative activity was significantly higher at the luminal border compared with the invasive margin (P<0.001), although the two compartments were also significantly correlated with each other. Tumours with low proliferation at the invasive margin had a significantly poorer prognosis both in univariate (P = 0.014) and in multivariate survival analyses (P = 0.042). We conclude that Dukes' B colorectal cancers exhibit a systematic spatial heterogeneity with respect to proliferation, and tumours with low proliferation at the invasive margin had a poor prognosis. The present data independently confirm recent results from the authors, and provide new insights into the understanding of tumour cell proliferation in colorectal cancer.  (+info)

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 ...
We investigated the means and timing by which mutations become fixed in the human colonic epithelium by visualizing somatic clones and mathematical inference. Fixation requires two sequential steps. First, one of approximately seven active stem cells residing within each colonic crypt has to be mutated. Second, the mutated stem cell has to replace neighbors to populate the entire crypt in a process that takes several years. Subsequent clonal expansion due to crypt fission is infrequent for neutral mutations (around 0.7% of all crypts undergo fission in a single year). Pro-oncogenic mutations subvert both stem cell replacement to accelerate fixation and clonal expansion by crypt fission to achieve high mutant allele frequencies with age. The benchmarking of these behaviors allows the advantage associated with different gene-specific mutations to be compared irrespective of the cellular mechanisms by which they are conferred.
TY - JOUR. T1 - The Crohns disease associated SNP rs6651252 impacts MYC gene expression in human colonic epithelial cells. AU - Matthews, Stephen M.. AU - Eshelman, Melanie A.. AU - Berg, Arthur S.. AU - Koltun, Walter A.. AU - Yochum, Gregory S.. PY - 2019/2. Y1 - 2019/2. N2 - Crohns disease (CD) is a debilitating inflammatory bowel disease (IBD) that arises from chronic inflammation in the gastrointestinal tract. Genome-wide association studies (GWAS) have identified over 200 single nucleotide polymorphisms (SNPs) that are associated with a predisposition for developing IBD. For the majority, the causal variant and target genes affected are unknown. Here, we investigated the CD-associated SNP rs6651252 that maps to a gene desert region on chromosome 8. We demonstrate that rs6651252 resides within a Wnt responsive DNA enhancer element (WRE) and that the disease associated allele augments binding of the TCF7L2 transcription factor to this region. Using CRISPR/ Cas9 directed gene editing and ...
Increased mucosal infiltration by leucocytes is a characteristic feature of inflammatory bowel disease and chemotactic factors play a key role in the recruitment of inflammatory cells. Intestinal epithelial cells act as the interface between the contents of the gut lumen and the internal milieu, which places them in an ideal position to detect and respond to proinflammatory stimuli.. In this study we have shown that human colonic cell lines, HT29-19A and Caco-2, express distinct patterns of chemokine secretion, both constitutively and after stimulation by inflammatory agonists. HT29-19A cells, which have a phenotype similar to that expected of Cl− secretory cells in the crypt epithelium,18 secreted high levels of both IL-8 and GROα, primarily in response to TNF-α and IL-1. These chemokines were secreted in parallel, probably via a common pathway as judged by their virtually identical time course for secretion and dose responsiveness to cytokine stimulation, suggesting that they may have ...

HLA-DR+ gut epithelial cells may present antigen to intraepithelial lymphocytes (IEL). This study aimed to isolate an IEL population from the human colon to activate CD3 + IEL by a human colonic epithelial cell line (HT-29), bearing different concentrations of class II antigen (HLA-DR). IEL were isolated by a mechanical method from six patients with ulcerative colitis (UC) and from 14 control patients. IEL were cocultured with HT-29 which had been induced to express class II molecules by gamma-interferon (IFN-gamma) in a dose dependent manner. The phenotype and the subsequent expression of activation markers by the IEL were determined to two colour flow cytometry. The IEL population had a CD4/CD8 ratio similar to that seen in tissue sections. In the mixed cell culture, the degree of IEL activation showed a positive correlation with the degree of HLA-DR expression by the HT29 cells and the IEL secreted a IFN-gamma like factor that in turn stimulated the HT-29. Thus, depending on their expression of HLA
TY - JOUR. T1 - The G-protein coupled receptor 56, expressed in colonic stem and cancer cells, binds progastrin to promote proliferation and carcinogenesis. AU - Jin, Guangchun. AU - Sakitani, Kosuke. AU - Wang, Hongshan. AU - Jin, Ying. AU - Dubeykovskiy, Alexander. AU - Worthley, Daniel L.. AU - Tailor, Yagnesh. AU - Wang, Timothy C.. PY - 2017/1/1. Y1 - 2017/1/1. N2 - Overexpression of human progastrin increases colonic mucosal proliferation and colorectal cancer progression in mice. The G-protein coupled receptor 56 (GPR56) is known to regulate cell adhesion, migration, proliferation and stem cell biology, but its expression in the gut has not been studied. We hypothesized that the promotion of colorectal cancer by progastrin may be mediated in part through GPR56. Here, we found that GPR56 expresses in rare colonic crypt cells that lineage trace colonic glands consistent with GPR56 marking long-lived colonic stem-progenitor cells. GPR56 was upregulated in transgenic mice overexpressing human ...

Our study shows that, with aging, colonic expression of insulin-like growth factor-1 (IGF-1) and IGF-binding protein-3 (IGFBP-3) is significantly increased and decreased, respectively. Colonic Bax protein levels are increased significantly with aging. Immunohistochemical localization of Bax protein shows a greatly increased expression in colonic crypts, especially in the upper portion of crypts. p53 ...
This project aims to better understand the role of Src kinase on the development of colon cancer. Enhanced Src expression and activity are commonly elevated in colon cancer, with progressively higher activity observed as tumors progress and metastasize, however, the specific mechanism by which Src promotes cancer progression are still under investigation. First, we examined the potential for biological cooperativity between APC (adenomatous polyposis coli), a tumor suppressor often mutated in early stages of colon cancer, and elevated Src activity, using conditionally immortalized mouse colon epithelial cell lines, IMCE (APC +/min) and YAMC (APC +/+) as a model. The APC genotype did not affect the ability of Src to disrupt cell-cell junctions and promote cell invasiveness. However, IMCE cells exhibited increased capacity for oncogenic Src-mediated anchorage-independent proliferation as compared to YAMC cells. This property was correlated with enhanced â-catenin expression and activity, but not ...
The aim of this project was to develop a system using the methods and techniques of computerised image processing and analysis in order to quantitatively describe patterns of movement in smooth muscle. The algorithms developed have been applied to the investigation of the co-ordination of motility of rabbit colon in vitro. The MAGISCAN 2 image processor used in this project is designed to analyse single still photographic images from a television camera. In the analysis of movement it is essential to process sequences of images with respect to time. These must be captured at a rate much faster than the period of the movements being investigated. To define precisely complex movements such as gut peristalsis large data sets must be used. Typically this requires the processing of several thousand photographs, the photographs being taken at a rate of three frames/sec over a period of half an hour. The most efficient way to achieve this is to capture, fully analyse and store the derived parameters of ...

A29 (Background) It has been estimated that approximately 1010 of normal adult colonic epithelial cells, each having a lifespan of 3-4days, are shed daily from the lower two-thirds of colon crypts; thus, using colonocytes to develop a screening test is an attainable goal. There is a need for sensitive and specific diagnostic and prognostic molecular markers which can monitor early patterns of gene expression in non-invasive exfoliated colonocytes shed in the stool. There were a few studies of RNA -based detection method because of the characteristics in stool. We report here the mass RNA analysis using stool in colorectal cancer. (Method) The study included 15 patients with colorectal cancer, and 15 control patients without neoplastic disease of the colon and rectum. RNA was isolated from routinely collected stool samples using a modified method. The expression levels of survivin, livin, Akt-1, caveolin, histone deacetylase(HDAC)1, matrix metalloproteinases(MMP)-2, MMP-7, MMP-9, MMP-12, hepatoma ...

TY - JOUR. T1 - Effect of fluid perfusion and cleansing on canine colonic motor activity. AU - Sarna, S. K.. PY - 1992. Y1 - 1992. N2 - We investigated the effect of absorbable and nonabsorbable fluid perfusion and cleansing on colonic motor activity in eight intact conscious dogs. Each dog was instrumented with an indwelling catheter in the proximal colon and seven strain gauge transducers on the entire colon. After an overnight fast, a control recording was made for 3 h, followed by 3 h of perfusion and 3 additional h of postperfusion recording. Next day, a 3-h recording was made when the colon was empty. The colon exhibited normal migrating and nonmigrating motor complexes in the control uncleansed state.

N1 - Copyright: Copyright 2020 Elsevier B.V., All rights reserved.. PY - 2005/10. Y1 - 2005/10. N2 - Water is an essential nutrient because it must be introduced from exogenous sources to satisfy metabolic demand. Under physiologic conditions, the colon can absorb and secrete considerable amounts of water even against osmotic gradients, thus helping to maintain the body fluid balance. Here we describe studies on both aquaporin (AQP) expression and function using cells isolated from the superficial and lower crypt regions of the rat proximal colon. The expression of AQP-3, -4, and -8 in isolated colonocytes was determined by semiquantitative RT-PCR ...

PY - 1992/9. Y1 - 1992/9. N2 - The aim of this study was to develop a chronic model suitable for repeated, long-term studies of the interaction of behavior and colonic function in unrestrained pigs. Cecostomies were created in three 20-30 kg micropigs under general anesthesia. Fistulas were created by suturing the bowel to the abdominal wall. Recordings were made by passing a small (8F) solid-state pressure transducer through the fistula into the proximal bowel and connecting it to a battery-operated data logger worn in a vest on the pigs back. Cecostomies have remained patent and trouble-free for over 18 months. No serious infections have occurred. Preliminary data from a total of thirteen 24-h recording sessions showed 54% of all contractile activity to be in the 2-4 cpm frequency range. ...

AU - Blotner, Steven. AU - Woods, Cindy J.. AU - Wargovich, Michael J.. PY - 2007/11/1. Y1 - 2007/11/1. N2 - Background & Aims: Orlistat is a weight management agent that selectively inhibits gastrointestinal lipase activity. Because of orlistats mode of action, increased fecal fat is presented to the colonic mucosa, and fecal bile acid and free fatty acid composition may be altered during treatment. Our aim was to assess the effect of treatment of obese subjects with orlistat 120 mg 3 times a day for 6 weeks on fecal lipid and bile acid parameters and colonic mucosal cell proliferation. Methods: Twenty-four obese (body mass index, 30-40 kg/m2) but otherwise healthy male and female subjects were enrolled in a single-center, randomized, double-blind, placebo-controlled, parallel-group study.

The relationship between intestinal epithelial integrity and the development of intestinal disease is of increasing interest. A reduction in mucosal integrity has been associated with ulcerative colitis, Crohns disease and potentially could have links with colorectal cancer development. The Ussing chamber system can be utilised as a valuable tool for measuring gut integrity. Here we describe step-by-step methodology required to measure intestinal permeability of both mouse and human colonic tissue samples ex vivo, using the latest equipment and software. This system can be modified to accommodate other tissues. An Ussing chamber was constructed and adapted to support both mouse and human tissue to measure intestinal permeability, using paracellular flux and electrical measurements. Two mouse models of intestinal inflammation (dextran sodium sulphate treatment and T regulatory cell depletion using C57BL/6-FoxP3DTR mice) were used to validate the system along with human colonic biopsy samples.

Recently, we delineated the mechanism in which graft-versus-host disease (GVHD), the major detrimental effect of allogeneic bone marrow transplantation, is enhanced by pathogenic colon-derived donor dendritic cells (DC) in a murine model. First, we will find the genetic signature of these DC using RNA sequence assay. Secondly, we will identify the equivalent human DC from post-transplant patients blood sample. The genetic profile of pathogenic colon-derived DC will provide us with a powerful biomarker to predict and treat severe GVHD. ...

We found that ABI-Nu binds to AT in the minor groove, while ABI-Nu and BF-MT are effective for tracking in the cytoplasm and mitochondria, respectively. These probes showed very large effective two-photon action cross section values of 2230, 1555, and 790 Göppert-Mayer units (1GM=10-50 cm4s photon-1 molecule-1) at 740nm with emission maxima at 473, 561, and 560nm, respectively, in each organelle. Using these probes, we quantitatively estimated the mean nuclear area and the ratios of nuclei to cytoplasm and mitochondria to nuclei in human colon ...
Descending rabbit colon, stripped ofmuscularis externa, absorbs Na and Cl under short-circuit conditions and exhibits a residual ion flux, consistent with HCO3 secretion, whose magnitude is approximately equal to the rate of active Cl absorption. Net K transport was not observed under short-circuit conditions. The results of ion replacement studies and of treatment with ouabain or amiloride suggest that the short-circuit currentI sc is determined solely by the rate of active Na transport and that the net movements of Cl and HCO3 are mediated by a Na-independent, electrically-neutral, anion exchange process. Cyclic AMP stimulates an electrogenic Cl secretion, abolishes HCO3 secretion but does not affect the rate of Na absorption under short-circuit conditions. Studies of the effect of transepithelial potential difference on the serosa-to-mucosa fluxesJ sm i of Na, K and Cl suggest thatJ sm Na ,J sm K and one-third ofJ sm Cl may be attributed to ionic diffusion.

博士論文. Volume regulation is one of the most important cell functions to maintain cell homeostasis in a variety of physiological and pathological conditions, where cells are subject to osmotic perturbation. Although colon crypts have been reported to shrink during Cl,SUP,-,/SUP, secretion in response to secretagogue stimulation, it is not yet clear whether or how individual secretory cells located in colon crypts restore their cell volume. To study this, he visualized individual cells in the crypt isolated from the guinea pig distal colon using two-photon laser scanning microscopy, and their volume changes in response to carbachol (CCh), a cholinergic agonist, were compared with those of a human colonic epithelial T84 cell line. Both T84 cells and fundus crypt cells, but not upper crypt cells, showed shrinkage (termed a secretory volume decrease: SVD) after CCh stimulation, and surprisingly, even under continuous stimulation by CCh, they recovered their original cell volume (called a ...
We (30) have recently reported that the majority of mouse LS colon sensory neurons respond to heat, protons, and capsaicin, consistent with the expression of TRPV1 channels. In the present report, we examined, in greater detail, the acid-sensitive currents in this population of colon sensory neurons as well as in a second TL sensory pathway innervating the distal colon. We found that visceral sensory neurons labeled from the colon are functionally distinct from unlabeled neurons, which likely project to nonvisceral targets, such as the skin or muscle. Whereas most unlabeled DRG neurons generated transient amiloride-sensitive currents in response to acid, most LS and TL colon sensory neurons responded with slowly activating, sustained currents that were reversibly inhibited by the TRPV1 blocker capsazepine. Consistent with the role of TRPV1 as the principal mediator of acid-sensitive currents in colon sensory neurons, the peak current and fraction of neurons responding to acid were significantly ...

TY - JOUR. T1 - Ureteral replacement with reconfigured colon substitute. AU - Pope, John. AU - Koch, Michael. PY - 1996/5. Y1 - 1996/5. N2 - Purpose: Upper ureteral defects are often too extensive to repair by direct anastomosis or with use of a bladder flap. Ureteral substitution may be the only remaining alternative to restoring urinary drainage from the kidney to the bladder. This effect is usually achieved by interposing a segment of small bowel between the proximal collecting system and bladder. If ileum is not available other substitution alternatives must be sought. Materials and Methods: We report a new technique in which a tube constructed from a small piece of ascending colon was used to replace a large ureteral defect. Results: Excellent short-term results were achieved by replacing the strictured ureteral segment with a reconfigured colon segment as shown by symptomatic and radiographic improvement. Conclusions: A reconfigured colon segment can be used for ureteral reconstruction in ...
Aldosterone is a major regulator of Na+-absorptive and K+-secretory processes in the distal segment of mammalian colon. In this study, the distribution of aldosterone-sensitive cell types in isolated rat distal colon was determined using site-directed intracellular microelectrodes, specific Na+- and K+-channel blockers, and aldosterone-receptor binding techniques. Electrophysiological data indicated that aldosterone induced parallel apical membrane Na+ and K+ conductances, mainly in surface cells and to a significantly lesser degree in crypt cells. Scatchard analyses of aldosterone-receptor binding in cytosolic fractions revealed the maximum number of specific binding sites in whole mucosal homogenate and in the upper one-third and lower two-thirds of isolated crypt units to be 74.9 ± 2.0, 59.8 ± 2.4, and 59.3 ± 3.2 fmol/mg protein, respectively, indicating the presence of aldosterone receptors in the crypt cell population. We conclude that in rat distal colon aldosterone-induced Na+ and K+ ...

Colorectal cancer (CRC) is a highly heterogeneous disease worldwide. Long non‑coding RNA (lncRNA) tumor suppressor candidate 7 (TUSC7) plays a crucial role in the development of several cancers. However, the role of TUSC7 in the tumorigenesis of CRC has not been explored. The TUSC7‑overexpressing CRC cell lines SW480 and CaCo‑2 were generated to investigate the effects of TUSC7 on the growth, migration, invasion and epithelial‑mesenchymal transition (EMT) of CRC cells. CCK‑8, wound‑healing and Transwell assays were used to evaluate CRC cell proliferation, migration and invasion. The mRNA and protein expression of TUSC7 were detected by quantitative real‑time PCR and immunoblotting, respectively. In the present study, we observed that the expression of TUSC7 was decreased in CRC cells compared to the expression in the normal colon epithelial cell line NCM460. Moreover, overexpression of TUSC7 inhibited CRC cell proliferation, metastasis, invasion and EMT. These findings indicated ...

In development of colorectal cancer (CRC), stem cell (SC) overpopulation underlies tumor initiation and progression, but it is incompletely understood which dysregulated mechanisms cause SC overpopulation. Because neuroendocrine cell (NEC) and SC populations both reside in the SC niche at the normal crypt bottom, we hypothesized that i) NECs play a role in maintaining the SC population, and ii) changes in the NEC population contributes to SC overpopulation and altered epithelial: stromal interactions during tumorigenesis. Immunofluorescence mapping and flow cytometry were used to analyze SC niche structure and cell-cell interactions in normal and neoplastic colonic tissues from Caucasian and African-American patients. In normal colonic crypts, most cells (77%) staining positively for the colonic SC marker ALDH1, also co-stained for the NE cell marker chromogranin-A (CGA). In the progression from normal to normal-appearing FAP to adenomatous to malignant colonic tissue, the proportion of ...

Another perplexing aspect of the /32-microglobulin association of CD1 proteins has recently been demonstrated by a report of P2microglobulin-independent expression of the human C D l d protein by intestinal epithelial cells. Immunoprecipitations from lysates of =I-labeled normal colonic epithelial cells performed with these mAbs, or with a mAb raised against a bacterial fusion protein constructed from the human C D l d cDNA sequence (Bilsland and Milstein, 1991), revealed a 100-kDa band under nonreducing conditions and a single 37-kDa band after reduction. 1987a). In similar fashion, two separate epitopes have been defined on the C D l b molecule, whereas the four anti-CDlc mAbs so far examined in this fashion appear to bind to the same or overlapping epitopes (Amiot et al. 1986, 1987b; Favaloro et al. 1987a). The relationship of these serologic epitopes to the protein structure of CD1 is currently unknown. , 1989). This variable reactivity with trypsin-cleaved CDla further underscores the ...

The Mets arent expected to make Bartolo Colon available at this years trade deadline, Andy Martino of the New York Daily News reports, barring a situation where trading him would somehow directly improve their playoff chances. Colon, Dillon Gee and Jon Niese were all being shopped by the Mets during the offseason but none were dealt, a non-move that could end up being a prudent one for the team given that Zack Wheeler was lost for the season due to Tommy John surgery.. Colon has essentially been seen as a trade candidate ever since he signed his two-year, $20MM free agent contract in January 2014. As Martino puts it, the Mets might has well have issued Colon a jersey with PLACEHOLDER on the back as the thinking was that the Mets would eventually use the veteran as a trade chip once one of their younger arms was ready to take his spot in the rotation. The Mets didnt get much interest about Colon at last years trade deadline, however, and despite testing his market over the winter, the ...

The multigenic nature of human tumors presents a fundamental challenge for cancer research. To capture this genetic complexity we generated multigenic models of colon cancer in Drosophila-double, triple and quadruple combinations of transgenes representing mutations found together in sequenced human colon tumors. We then investigated the tumorigenic and metastatic potential of each of these combinations by targeting them specifically to the adult Drosophila colon as it shows important similarities to the human colon in terms of the signaling pathways that regulate its maintenance. We focused our initial analysis on three quadruple combinations: 1) rasG12V p53RNAi apcRNAi ptenRNAi, 2) rasG12V p53RNAi apcRNAi Smad4RNAi and 3) egfr p53RNAi apcRNAi Smad4RNAi. These models recapitulated key features of human cancer, including proliferation and multilayering of the colon epithelium, evasion of apoptosis and a senescence-like process, epithelial-mesenchymal-transition (EMT), migration and dissemination ...
put him on his back, i said, oozing confidence, im going through the abdomen. they nodded. and did so. once everything was ready we all started scrubbing and the sister started draping the patient. i tried to envisage what i would be doing in a while. i decided that id reflect the right colon up and pull the ivc out of the way, rather than reflecting the left colon up, which would mean id have more to do with the aorta. my reason had little to do with the blood vessels but rather had to do with the fact that the right colon can be reflected right out of the way whereas the left colon cant because it continues down to the rectum which is pretty much fixed. truth be told, the aorta is easier to work with than the ivc, but i just felt id get more exposure on the right. in my mind i was just trying to convince myself that it was going to be fine when the great orthopaedic consultant entered. he greeted us all and thanked me for my help before quickly going into the theater to make sure ...
BACKGROUND: Colon cancer occurrence is increasing worldwide, making it the third most frequent cancer. Although many therapeutic options are available and quite efficient at the early stages, survival is strongly decreased when the disease has spread to other organs. The identification of molecular markers of colon cancer is likely to help understanding its course and, eventually, to uncover novel genes to be targeted by drugs. In this study, we compared gene expression in a set of 95 human colon cancer samples to that in 19 normal colon mucosae, focusing on 401 genes from 5 selected pathways (Apoptosis, Cancer, Cholesterol metabolism and lipoprotein signaling, Drug metabolism, Wnt/beta-catenin ...

Our colon can be a magnet of all the things that we eat-thats why it serves as a double edge. Why? IT may be of benefit if we live a nutritious lifestyle i.e. balanced diet, eating nutritious foods, etc… however, it can be very detrimental if we are the type of person who lives in a quick lifestyle-fast foods, canned goods, processed meat and the likes. This is where our colon can be both harmful and beneficial.

When beginning a detox, the first organ that needs to be addressed is the colon. The colon is the bodys number 1 elimination channel, and unless it is properly working, detoxifying other organs of the body will be nowhere near as beneficial-and in some cases, can even cause harm. This is because if you are detoxing with a sluggish colon, the toxins we are trying to remove from the body will have no way of exiting. They can then recirculate around the body, causing damage..
