Affymetrix Mouse Gene 1.0 ST Array (mogene10st)
Description
Engagement of the ICOS receptor represents a key event in a process that culminates in Bcl6 expression and acquisition of the TFH and TFR phenotype. To better understand the essentials of ICOS-mediated signaling pathway, we profiled the changes in gene expression elicited after co-ligation of ICOS and CD3 compared with CD3 ligation alone.
Publication Title
A p85α-osteopontin axis couples the receptor ICOS to sustained Bcl-6 expression by follicular helper and regulatory T cells.

Description
Preeclampsia (PE) is a complex, heterogeneous disorder of pregnancy, demonstrating considerable variability in observed maternal symptoms and fetal outcomes. We recently identified five clusters of placentas within a large gene expression microarray dataset (N=330, GSE75010), of which four contained a substantial number of PE samples. However, while transcriptional analysis of placentas can subtype patients, we hypothesized that the addition of epigenetic information should reveal gene regulatory mechanisms behind the distinct PE pathologies. We, therefore, subjected 48 of our samples to Infinium Human Methylation 450K arrays and investigated relationships between the gene expression and DNA methylation data.

Description
Preeclampsia (PE) is a complex, heterogeneous disorder of pregnancy, demonstrating considerable variability in observed maternal symptoms and fetal outcomes. We hypothesized that this heterogeneity is due to the existence of multiple molecular forms of PE. To address our hypothesis, we created a large (N=330) human placental microarray data set consisting of seven previously published studies (GSE30186, GSE10588, GSE24129, GSE25906, GSE43942, GSE4707, and GSE44711) and 157 highly annotated samples from a BioBank (below).

Description
Fetal growth restriction (FGR) is a heterogeneous disorder of pregnancy associated with pathologically low fetal and neonatal weights. We hypothesized that FGR consists of multiple placental subtypes, similar to what we have observed in preeclampsia. To address this hypothesis, we assembled a fetal growth-focused human placental microarray data set (N=97) consisting of 20 new normotensive suspected FGR samples (below), in addition to term controls (N=26) and hypertensive suspected FGR samples (N=51) from GSE75010.
Publication Title
Placental transcriptional and histologic subtypes of normotensive fetal growth restriction are comparable to preeclampsia.

Description
Skeletal muscle is a post-mitotic tissue that exhibits an extremely low turnover in the absence of disease or injury. At the same time, muscle possesses remarkable regenerative capacity mediated by satellite cells (SCs) that reside in close association with individual myofibers, underneath the fibers basal lamina. Consistent with the low turnover of the muscle, SCs in adult animals are mitotically quiescent and therefore provide an excellent model to study stem cell quiescence. As an organism grows older, the resident stem cells are exposed to a deteriorating environment and experience chronological aging. In stem cells with high turnover, the effects of chronological aging are superimposed upon the effects of the replicative aging that results from DNA replication and cell division. On the contrary, SCs experience minimal replicative aging due to their low turnover. They are thus a good model to study the consequence of chronological aging of quiescent stem cells. We performed microarray analysis of quiescent and activated SCs from both young and aged mice to understand the global gene expression profile underlying stem cell properties such as quiecence and self-renewal, and to understand how the transcriptome of a quiescent stem cell pouplation changes with age.

Description
Evaluation of transcriptional changes in the striatum may be an effective approach to understanding the natural history of changes in expression contributing to the pathogenesis of Huntington disease (HD). We have performed genome-wide expression profiling of the YAC128 transgenic mouse model of HD at 12 and 24 months of age using two platforms in parallel; Affymetrix and Illumina. We performed gene expression profiling on the same striatal mRNA across both platforms.

Description
TNF-a is increased in the synovial fluid of patients with rheumatoid arthritis and osteoarthritis. TNF-a activates MEK/ERK in chondrocytes; however the overall functional relevance of MEK/ERK to TNF-a-regulated gene expression in chondrocytes is unknown. Chondrocytes were treated with TNF-a with or without the MEK1/2 inhibitor U0126 for 24 h. Microarray analysis was used to identify genes regulated by TNF-a in a MEK1/2-dependent fashion.
