Affymetrix Human Genome U133B Array (hgu133b), Affymetrix Human Genome U133A Array (hgu133a)
Description
Two biological replicate experiments were performed to estimate the bias of the gene expression pattern of infected and non-infected HEp-2 cells. Microarrays hybridized with RNA from 2 h of non-infected HEp-2 cells were used as reference chips for the comparison with microarrays hybridized with RNA from 2 h and 4 h of eukaryotic cells exposed to wt-bacteria and .fasX-mutant. As a reference for chips hybridized with RNA prepared from 6 h p. i. and 8 h p. i. of both GAS-infected HEp-2 cells we used chips that were hybridized with RNA isolated from non-infected cells 8 h p. i. We also compared the microarray data from 2 h of non-infected HEp-2 cells with those from 8 h of non-infected HEp-2 cells to determine the influence of the extended culture on the non-infected cells. Only such genes which were differentially regulated after infection with wt-bacteria and .fasX-mutant infected cells and not differentially present in unequal amounts between the 2 h and 8 h of controls were included in the subsequent statistical analysis.

- Affymetrix Mouse Expression 430A Array (moe430a)
Description
The goal of this study was to examine whether immune responses to Plasmodium chabaudi infection differ between the sexes and are altered by the presence of gonadal steroids. Gonadally-intact males were more likely than intact females to die following P. chabaudi infection, exhibit slower recovery from infection-associated weight loss, hypothermia, and anemia, have reduced IFN-associated gene expression and IFN production during peak parasitemia, and produce less antibody during the recovery phase of infection. Gonadectomy of male and female mice altered these sex-associated differences, suggesting that sex steroid hormone, in particular androgens and estrogens, may modulate immune responses to infection.

Involvement of gonadal steroids and gamma interferon in sex differences in response to blood-stage malaria infection.

- Affymetrix Human Gene 1.0 ST Array (hugene10st)
Description
IL-27 has been shown to play a role in modulating functions of diverse cell types like Th1, Th2, NK and B cells demonstrating both pro and anti-inflammatory roles. It is also capable of inducing STAT1, STAT3 and ISG's. To investigate the role of IL-27 on hepatocytes, Huh7.5 cells were treated with Il-27 and analysed the differentially expressed genes by microarray analysis.

Impact of IL-27 on hepatocyte antiviral gene expression and function.

Illumina Genome Analyzer II
Description
Purpose: To investigate the quaternary structures of Rhodopsin-family GPCRs. Method: Analyzed 60 receptors from HEK 293T cells. Results: 1) Most of these receptors are monomers. 2) The phylogenetic distribution of dimers suggests that monomers have an evolutionary advantage due to constraints imposed by dimerization on rates of receptor diversification. Overall design: To investigate the quaternary structures of 60 Rhodopsin-family GPCRs expressed in HEK 293T cells using type-1 and -3 BRET assays.

Description
To determine what DNA methylation and gene expression changes occur following EBV transformation. B-cells were isolated from 3 donors. Resting, CD40 activated and EBV transfromed cells from each donor was analyzed. Each sample was assayed using Affymetrix expression arrays and whole genome bisulfite sequenicng. Additional time points during transformation and activation were sequenced as well, but not assayed for expression.
