Effects of gentamycin on gene expression of kidney in SD rats

ABSTRACT: To investigate the gene expression profile of genamycin induced nephrotoxicity in a time-series aspect, SD rats were administrated once daily with saline, genamycin 80 mgkg for 28 consecutive days by intramuscular injection folled by 28 days recovery. Kidney samples were collected for microarray analysis and histological examination. There were 4360 and 4323 regulated genes for females and males, respectively, however, the overlapping expression genes coregluated at each time point were few, with 2 for females and 12 for males. By Principle Component Analysis and Hierarchical Cluster, the gene expression patterns were apparently associated with the disease stage of the nephrotoxicity,while GO Annotation showed the biological processes were specific to each course of this nephrotoxicity.Our studymapped the different gene expression patterns at the initiation, development and recovery stage of gentamycin-induced nephrotoxicity Gene expression in kidney from SD rats administrated once daily with saline or 80 mg/kg genamycin by intramuscular injection for 28 consecutive days follwed by 28 days recovery were measured using Aglient Rat Whole Genome 4*44 k array

Transcriptomic characterization of temperature stress responses in larval zebrafish

Project description:96 hpf zebrafish larvae were exposed to cold (16 C) or heat (34 C) stress for 2 and 48h. Time-matched controls were maintained at 28 C. The transcriptional responses elicited by temperature stress in larval zebrafish were investigated by microarray.

Mining potential serum biomarkers for gastric adenocarcinoma using quantitative proteomics

Project description:Serum is a valuable body fluid to diagnose cancer as it can be accessed with minimal invasive techniques. Studying the cancer serum proteome provides valuable insights into the pathophysiology of tumor progression. Gastric adenocarcinoma is an aggressive cancer resulting in poor prognosis, mainly due to the lack of specific early diagnostic biomarkers. To this end, we used an iTRAQ-based quantitative proteomic approach to identify differentially expressed proteins in the sera of patients diagnosed with gastric cancer. Our study resulted in the identification of 643 proteins in the serum, of which 48 proteins were found to be overexpressed and 11 proteins underexpressed in gastric cancer when compared with healthy controls. We used multiple reaction monitoring assays to validate the overexpression of potential biomarkers. This catalog of serum-based biomarkers will aid in diagnosis and prognosis of gastric cancer.

A Universal 384-Well Proteomic Sample Preparation Platform for High-Throughput Screening and Biomarker Discovery

Project description:Major advances have been made to develop an automated universal 384-well plate sample preparation platform with high reproducibility and adaptability for extraction of proteins from cells within a culture plate. An in-solution digest strategy is employed to generate peptides from the extracted proteins for LC-MS analysis in the 384-well plate. Method evaluation utilized HeLa cells cultured in the 384-well plate ranging from 500 – 10,000 cells. Digestion efficiency was excellent in comparison to the commercial digest peptides standard with minimal sample loss while improving sample preparation throughput by 20 – 40 fold. Analysis of six human cell types, which included two primary cell samples identified and quantified approximately 4,000 proteins for each sample in a single LC-MS/MS injection with as little as 100 – 10,000 cells depending on cell type demonstrating universality of the platform. Implementation of the comprehensive 384-well format protocol for processing cells to clean digested peptides enables large-scale biomarker validation and compound screening through proteomic analysis.

Temperature dependent gene expression levels at 28°C and 37°C for rhizophere Rhizosphere Originating Biocontrol Strain Pseudomonas aeruginosa M18

Project description:To further understand the gene expression characteristics of originating biocontrol strain Pseudomonas aeruginosa M18, we have applied whole genome microarray expression profiling as a discovery platform to to specify the temperature dependent expression of M18 genome at rhizosphere and human body temperature. We selected 28°C as temperature representative of the rhizosphere niches and 37°C for human body. The results from the temperature dependent transcriptome analysis are consistent to our previous published data that the phzM, ptsP and lasI genes expression is upregulated at 37°C. The comparison analysis of the M18 genome expressional profiles at 28°C and 37°C indicated a total of 605 gene expressed in a temperature dependent manner over about two fold at 28°C compared that at 37°C, covering 10.6% genes in M18 whole genome. Cells were grown to OD600=5.0-6.0 (late exponential phase) in LB medium at 28℃ and 37℃, respectively. Three independent experiments were performed at each time.

Methyl ketone production by Pseudomonas putida is enhanced by plant-derived amino acids

Project description:Methyl ketone production by P. putida with A. thaliana and switchgrass hydrolysates obtained by dilute acid pretreatment led to the identification of plant-derived amino acids, rather than mono-aromatics, as key stimulative components of these hydrolysates. Shotgun proteomics indicated that the amino acids had a specific inductive effect on proteins involved in fatty acid biosynthesis, leading to a 9-fold increase in methyl ketone titer when amending glucose-containing minimal medium with a defined set of amino acids.

Temperature dependent gene expression levels at 28°C and 37°C for Pseudomonas aeruginosa PAO1

Project description:To further understand the gene expression characteristics of Pseudomonas aeruginosa PAO1, we have applied whole genome microarray expression profiling as a discovery platform to specify the temperature dependent expression of PAO1 genome at soil and human body temperature. We selected 28°C as temperature representative of the soil niche and 37°C for human body. The results from the temperature dependent transcriptome analysis are consistent to our previous published data that the phzM, ptsP and lasI genes expression is upregulated at 37°C [11]. The comparison analysis of the M18 genome expressional profiles at 28°C and 37°C indicated a total of 596 genes expressed in a temperature dependent manner over two fold. Cells were grown to OD600=5.0-6.0 (late exponential phase) in LB medium at 28℃ and 37℃, respectively. Three independent experiments were performed at each time.
