Group IID secretory phospholipase A2 (sPLA2-IID), a heparin-binding sPLA2 that is closely related to sPLA2-IIA, augments stimulus-induced cellular arachidonate release in a manner similar to sPLA2-IIA. Here we identified the residues of sPLA2-IID that are responsible for heparanoid binding, are and therefore essential for cellular function.

Matrilysin (matrix metalloproteinase-7) plays important roles in tumor progression. It was previously found that matrilysin binds to the surface of colon cancer cells to promote their metastatic potential. In this study, we identified annexin II as a novel membrane-bound substrate of matrilysin. Treatment of human colon cancer cell lines with active matrilysin released a 35 kDa annexin II form, which lacked its N-terminal region, into the culture supernatant. The release of the 35 kDa annexin II by matrilysin was significantly enhanced in the presence of serotonin or heparin....

Palytoxin stimulated a cation-dependent short-circuit cur-rent (Isc) in rat distal and proximal colon in a concen-tration-dependent fashion when applied to the mucosal surface of the tissue. The distal colon exhibited a higher sensitivity to the toxin. The palytoxin-induced Isc was blocked by vanadate but was resistant to ouabain or scilliroside, suggesting the conversion of a vanadate-sen-sitive H + /K + -ATPase into an electrogenic cation trans-porter.

The large intestine of breast-fed infants is colonized predominantly by bi®dobacteria, which have a protective e€ect against acute diarrhea. In this study we report for the ®rst time the identi®cation of human milk peptides that selectively stimulate the growth of bi®dobacteria. Several bi®dogenicpeptideswerepuri®edchromatographically from pepsin-treated human milk and identi®ed as proteolytically generated fragments from the secretory component of the soluble polyimmunoglobulin receptor and lactoferrin;...

The heat-stable enterotoxin peptides (ST) produced by enterotoxigenicEscherichia coliare one of the major causes of transitory diarrhea in the developing world. Toxin bind-ing to its receptor, guanylyl cyclase C (GC-C), results in receptor activation and the production of high intracellular levels of cGMP. GC-C is expressed in two differentially glycosylated forms in intestinal epithelial cells. Prolonged exposure of human colonic cell lines to ST peptides induces cellular refractoriness to the ST peptide, in terms of intra-cellular cGMP accumulation....

We determined differentially expressed genes in HT29 human colon cancer cells, both after short treatment with methotrexate (MTX) and after the resistance to MTX had been established. Screening was performed using Atlas Human Cancer 1.2K cDNA arrays. The analysis was carried out using Atlasimage 2.01 andgenespring6.1 software.

The expression of the colonic mitochondrial 3-hydroxy 3-methyl glutaryl CoA (mHMGCoA) synthase,a key con-trol site of ketogenesis from butyrate,is lower in germ-free (GF) than in conventional (CV) rats. In contrast,the activity of glutaminase is higher. The objective of this study was to investigate whether the intestinal flora can affect gene expression through short chain fatty acid (SCFA) and butyrate production. GF rats were inoculated with a con-ventional flora (Ino-CV) orwitha bacterial strainproducing butyrate (Clostridium paraputrificum,Ino-Cp) or not (Bifidobacterium breve,Ino-Bb).

N-6 polyunsaturated fatty acids (PUFAs) may be associated with increased risk of colon cancer, whereas n-3 PUFAs may have a protective effect. We examined the effects of docosahexaenoic acid (DHA), eicosapentaenoic acid and arachidonic acid on the colon carcinoma cell lines SW480 derived from a primary tumour, and SW620 derived from a metastasis of the same tumour.

Galloylated and nongalloylated catechin conjugates with cysteine deriva-tives have been synthesized and evaluated for their capacity to scavenge free radicals and to influence crucial functions (cell cycle, apoptosis) in HT29 colon carcinoma cells. We show that the nonphenolic part of the molecule modified the capacity of catechins to donate hydrogen atoms and to transfer electrons to free radicals.

Human colon adenocarcinoma cells (HT29-ATCC) and the clone HT29-5F7 were cultured under conditions that differentiate cells to a polarized intestinal phenotype. Differentiated cells showed the presence of junctional complexes and intercellular lumina bordered by microvilli. Intestinal brush border hydrolase activities (sucrase, aminopeptidase N, lactase and mal-tase) were detected mainly in differentiated HT29-ATCC cells compared with the differentiated clone, HT29-5F7.

Physalis philadelphicaLam, commonly known as a tomatillo, is a staple of the Mesoamerican cuisine. In our laboratory, an ethyl acetate-soluble extract and four withanolides [ixocarpalactone A (IxoA), ixocarpalac-tone B, philadelphicalactone B, and withaphysacarpin] were isolated. Stud-ies conducted on Hepa-1c1c7 hepatoma cells revealed that withanolides were potent inducers of quinone reductase, suggesting possible cancer chemo-protective activity.
