Project description:Microarrays were used to analyse gene expression underlying early tumourigenesis in Eker rats. Distinct classes of up- and downregulated genes were identified in different preneoplasic lesion vs. microdissected normal (healthy) renal tubules. Laser capture microdissected renal basophilic atypical tubule (bAT) and basophilic atypical hyperplasia (bAH) and healthy tissue (HT) of 6-months aristolochic acid (AA)- and ochratoxin A (OTA)-treated and control (C) male Eker rats were isolated for RNA extraction and microarray analysis in order to investigate gene expression profiles induced by AA and OTA as well as to differentiate pathways specific for the bAT to bAH progression. Keywords: gene expression study, preneoplasic lesion vs. microdissected normal renal tubules
Project description:Ochratoxin A gene expression profiling in liver and kidney, with time points of exposure from 7 days to 12 months Experiment Overall Design: three replicates for each timepoint measured, control and ochratoxin A treated for both liver and kidney. <br><br>Note that files GSM62732.CEL and GSM62733.CEL, and files GSM62730.CEL and GSM62739.CEL as downloaded from GEO contain identical data.
Project description:Male Sprague-Dawley rats were used to establish exhausted-exercise model by motorized rodent treadmill. Yu-Ping-Feng-San at doses of 2.18 g/kg was administrated by gavage before exercise training for 10 consecutive days. Quantitative proteomics was performed for assessing the related mechanism of Yu-Ping-Feng-San.
Project description:Analysis of LBNF1 rat testes from controls, containing both somatic and all germ cell types and from irradiated rats in which all cells germ cells except type A spermatgogonia are eliminated. Results provide insight into distinguishing germ and somatic cell genes and identification of somatic cell genes that are upregulated after irradiation.
Project description:A time course of orotic acid induced fatty liver disease. Kyoto and Wistar strain rats were exposed to orotic acid for days 1, 3 and 14. Controls are also included.
