Project description:To identify the gene expression changes in NRAS mutant cell line SKMEL-103, KRAS mutant cell line AsPC1 and HRAS mutant cell line RH-36 upon BAY 11-7082 treatment, we analyzed these cell line with either control DMSO or BAY 11-7082 treatment via RNA sequencing.
Project description:Parasite gene expression differences have been reported previously between RH-ERP, RH-JSR and GT1. To independently confirm these gene expression differences, we examined the parasite gene expression profiles of RH-ERP, RH-JSR and GT1 through microarray.
Project description:Previous studies have shown that continuous in vitro passage can result in changes to the global gene expression profiles in mammalian cells. To examine the extent of gene expression differences between highly homologous type I strains, we took advantage of the T. gondii Affymetrix microarray containing probes to more than 8,000 genes. We compared the RH-JSR and GT1 strains, two isolates that share the small plaque phenotype, to the large plaque isolate RH-ERP2009. Following hybridization and normalization of data, we used two independent methods to generate lists of genes with expression differences that were statistically significant and 2-fold or greater in at least one sample. The 1-way ANOVA (P ≤ 0.05) identified 520 genes that were significantly differentially expressed between GT1, RH-ERP2009 and RH-JSR. Statistical Analysis of Microarray (SAM) (FDR = .05%) analysis identified 475 transcripts that were differentially expressed. Both lists were combined (610 genes) and used to perform pairwise fold comparisons between the three samples. This process identified 113 genes that were similarly expressed in GT1 and RH-JSR and differentially expressed in RH-ERP2009. Differentially expressed genes were located across all chromosomes and showed no pattern of clustering to one particular region of the genome. Interestingly, three out of 34 ABC transporters (ToxoDB) were significantly upregulated in RH-ERP2009 (hypergeometric distribution, P = 0.01)
Project description:These data is from 10 day-old Hr(Rh-R)/Hr(Rh-R) vs Hr(Rh-R)/+ mice. Mouse 15k microarray from the Center for Applied Genomics was used to survey the gene expression. The data was acquired with ImaGene and processed with GeneSight from BioDiscovery. Keywords: Genetic mutants
Project description:The normally virulent type-I RH parasite is rendered avirulent when lacking ROP5. The avirulent phenotype is a consequence of interaction with the host innate immune system. We sought to understand if ROP5 alters host gene expression in order to escape host defenses. We saw no gene expression differences between host cells infected with wt (RH∆ku80) or RH∆ku80∆rop5 parasites. We have included uninfected HFF samples that were harvested in parallel with the infected samples.
