Project description:The purpose of this study was to characterize the gene expression profile of MDA-MB-231 breast cancer cells treated with various SCFA-hexosamine analogs to better understand the role of various modifications to this scaffold. Keywords: SCFA-hexosamine analog comparison
Project description:We aim to improve the yield and effectiveness of the Dutch colorectal cancer screening program by using a personalized screening strategy based on fecal Hemoglobin concentration in previous screening round for participants with a negative fecal immunochemical test (FIT).
Project description:Background: The possible impact of changes in diet composition for the intestinal microbiome is mostly studied after some days of adaptation to the diet of interest. The question arises if few days are enough to reflect the microbial response to the diet by changing the community composition and function. The present study investigated the fecal microbiome of pigs in a time span of four weeks after a dietary change to get an insight of the needed adaptation period. Four different diets were used differing in either protein source (field peas meal vs. soybean meal) or the concentration of calcium and phosphorus (CaP). Results: Twelve pigs were sampled at seven time points within four weeks after the dietary change. Fecal samples were used to sequence the 16S rDNA amplicons, to analyse the microbial proteins via LC-MS/MS and to determine the SCFA production. The analysis of OTU abundances and quantification values of proteins showed a significant separation of three periods of time (p=0.001). Samples from the first day are used to define the ‘Zero phase’, samples of weeks one and two are combined as ‘metabolic phase’ and an ‘equilibrium phase’ was defined based on samples from week three and four. Only in this last phase, a separation according to the supplementation of CaP was significantly detectable (p=0.001). No changes were found based on the corn-soybean meal or corn-field peas administration. The analysis of possible factors causing this significant separation showed only an overall change of bacterial members and functional properties. The metaproteomic approach yields a total of about 9700 proteins, which were used to deduce possible metabolic functions of the bacterialcommunity.

Project description:Fecal Exosomes from RCD and HFD (isolated from 12 months of their respective diets and purified by sucrose gradient) were orally gavaged to B6 mice for 14 days while they fed HFD. These exosomes were characterized for CD63+A33 duol positivity. After 14 days, liver tissue were harvested. RNA was isolated and sent to invitorgen for Affymetrix array. The purpose of the experiment was to see which set of genes go up or down after these exosomes treatment and their link to metabolic syndrome.
