Project description:A standard proteolytic digest of a human protein mixture, prepared at 1.5-fold to 3-fold protein concentration changes, and diluted into a constant background of yeast proteins. Similar to other datasets used for ground truth in quantitative studies, with the exception of being more granular, and much larger in terms of replicates, to enable more rigorous and accurate testing of quantitative algorithms.
Project description:Iron titration was performed (for replicates) into mixture of commercial standards (DFE, DFB, enterobactin, rhodotorulic acid, and ferrichrome), into cheese culture (JB 182), and E coli Nissle culture. Then iron concentration was kept constant (at 5 different concentrations) while the concentration of standard mixture was increased. This will be another way to determine Kd of each compound.
Project description:RNA-Seq on libraries made from External RNA Controls Consortium (ERCC) external RNA controls, and a mixture of mRNA from Drosophila melanogaster S2 cell and ERCC mRNAs. We evaluated performance of RNA-Seq on known synthetic PolyA+ mRNAs from the External RNA Controls Consortium (ERCC) alone and in mixtures with PolyA+ mRNA from Drosophila S2 cells. ERCC mRNAs were obtained under Phase V testing from the National Institutes of Standards and Technology (NIST). The ERCC pool contained 96 species of mRNA of various lengths and GC content covering a 2^20 concentration range. Libraries were constructed using 100ng S2 mRNA with 5ng, 2.5ng, or 1ng ERCC mRNAs, and using 50ng ERCC mRNA without S2 cell mRNA. Our data shows an outstanding linear fit between RNA-Seq read density and known input amounts.
Project description:Micro algae's are used as alternative protein source in human and animal diets. Besides micro algae contain substantial amounts of proteins they also contain a high concentration of, often unique, biological and chemical substances with potential to induce beneficial and health promoting effects in humans and animals. This study was set up to evaluate the potential of these substances to improve (intestinal) health. The effect of extracts prepared from 3 monocultures of micro algae's (Chlorella vulgaris [C], Haematococcus pluvialis [H], and Spirulina platensis [S]) and a mixed culture of micro algae's (AM; a mixture of Scenedesmus sp. and Chlorella sp. ) was studied in the presence and absence of the enterotoxigenic bacterium Escherichia coli k99 strain (ETEC, [E]) as an in vitro challenge. The E.coli-k99 strain with adhesion factor F41 (41/32) was isolated from a mastitis-infected udder. Gene expression was measured in cultured intestinal porcine epithelium cells (IPECJ2 cell line) after 2 and 6 hours incubation with C, H, and S extracts, and after 6 hours with the AM extract, using “whole genome” porcine microarrays. Gene expression profiles were analysed using functional bioinformatics programs to provide insight in the biological processes induced by micro algae extracts.

Project description:Purpose: Next-generation sequencing (NGS) has revolutionized systems-based analysis of cellular pathways. The goals of this study are to compare the transcriptome differences between knockdown LINC00205 and negative control gastric cancer cells. Methods: Total RNA from the BGC823 cells with LINC00205 knockdown and negative control were isolated using RNeasy mini kit (Qiagen, Germany). Paired-end libraries were synthesized by using the TruSeq RNA Sample Preparation Kit (Illumina, USA) following TruSeq RNA Sample Preparation Guide. Briefly, The poly-A containing mRNA molecules were purified using poly-T oligo-attached magnetic beads. Purified libraries were quantified by Qubit 2.0 Fluorometer (Life Technologies, USA) and validated by Agilent 2100 bioanalyzer (Agilent Technologies, USA) to confirm the insert size and calculate the mole concentration. Cluster was generated by cBot with the library diluted to 10 pM and then were sequenced on the Illumina HiSeq X-ten (Illumina, USA). The library construction and sequencing was performed at Shanghai Biotechnology Corporation. STAR (version:2.7.6a) was used to map the cleaned reads to the human GRCh38 reference genome with two mismatches 1. Then ,we ran Subread/featureCounts (version:2.0.2) with a reference annotation to generate gene expression counts and FPKM values for known gene model. Results: We identified a set of differentially expressed genes after LINC00205 knockdown. The result of GO and KEGG enrichment analysis showed high confidence of genes enriched in the function of cell proliferation, cell cycle, and cell adhesion, consistent with the canonical molecules of these pathways significantly modulated. Conclusion:The results suggested that LINC00205 could affect the key regulated pathway that controls the progression and metastasis of GC.

Project description:Exposure to ambient particulate matter (PM) is associated with adverse health effects. Yet, due to the complexity of its chemical composition, the molecular effects of PM exposure and the mechanism of PM-mediated toxicity remain largely unknown. Here, we show that water-soluble inorganics such as nitrate and sulfate ions, rather than PM themselves, are responsible for perturbing gene expression in the lungs by rapidly penetrating the lung surfactant barrier to the alveolar region. Furthermore, from high-throughput sequencing of lung adenocarcinoma cells, we find that exposure to nitrate and sulfate ions activates the cholesterol biosynthetic metabolism and induces the expression of genes related to tumorigenesis and inflammatory response, particularly interferon-gamma. Transcriptome analysis of mouse lungs exposed to nitrate/sulfate aerosols further supports our findings. Notably, we find that exposure to nitrate/sulfate mixture leads to a unique gene expression pattern that is not observed when nitrate or sulfate is treated alone. Our work suggests the water-soluble ions as a potential source of PM-mediated toxicity and provides a roadmap to unveil the working mechanism of health hazards of PM exposure.
Project description:Open tenotomy of the Achilles tendon of 6 rats was performed. The animals were divided into two groups according to exposure of PM2.5 (particulate matter less than 2.5 µm): control group (Non-PM group) or PM exposure group (PM group). After 6 weeks of PM exposure, the tendon DNA was extracted and anlyzed. Genome-wide DNA methylation profiles were determinen. DNA amplicons were prepared using Differential Methylation Hybridization (DMH) method, subsequently hybridized on to the Customized Agilent Rat CpG island Microarray. The goal was to unravel the DNA methylation patterns in different subgropus of tendon tissue according to partciulate matter exposure.
