Description
Cells adapt to environmental stressors such as heat shock and extracellular acidosis through formation of nuclear membrane-less compartments called Amyloid bodies (A-bodies). Stressors activate formation of Amyloid bodies (A-bodies) via induction of ribosomal intergenic spacer RNA (rIGSRNA). RNA-seq on non-ribosome depleted RNA from human MCF7 cells exposed to heat shock (43C, 30 minutes) revealed the heat shock-specific expression profile of rIGSRNA. Overall design: Expression profile of the ribosomal intergenic spacer (i.e. rIGSRNA) in cells exposed to heat shock

Description
To analyse and understand the differentially expressed genes following treatment with synthetic androgen (R1881) Overall design: LNCaP or LAPC4 cells were plated in RPMI 1640 media with no phenol red and with 5% charcoal stripped serum, sodium pyruvate, penicillin and streptomycin. After 48h (to allow adnrogen deprivation), fresh media was added, with 96% ethanol or the synthetic androgen R1881 (10nM concentration). 24h later, cells were harvested for RNA purification using the QIAGEN RNeasy plus purification kit. RNA was then enriched for mRNA and then sequenced.

Description
Overview: We report here that gene expression in E13.5 wild type (WT) mouse lenses differs from the lenses of mice that conditionally lack the Prox1 transcription factor in the lens of their eyes (Prox1 cKO) as assayed by high throughput RNA sequencing (RNAseq). The methodology outlined herein is similar to a previous RNAseq experiment from our lab (Manthey et al., 2014a)(Geo ascension: GSE 49949), and the filtering and processing criteria for this experiment was published as well.(Manthey et al., 2014b). The mammalian lens is notable for its biased gene expression, where 90% of the observed protein is expressed by just 50 genes. RNAseq was employed to sequence past these highly expressed lens structural genes and report the relative abundance of both high and low expression genes. In this study we demonstrated that 642 genes were differentially expressed in the lenses of Prox1 cKOs as compared to WT lenses. These data were analyzed using the DAVID biostatical analysis package and we found that the expression of lens specific proteins, as well as cytoskeletal genes and genes that regulated the cytoskeleton were expressed at lower levels in Prox1 cKOs. This analysis showed that the expression of genes encoding extracellular matrix components and their regulators, as well as cell adhesion increased in Prox1 cKO lenses when compared to WTs. Description of Filtering Criteria: Our initial analysis identified 5,492 genes that were differentially expressed in Prox1 cKO lenses as compared to WTs as computed by Pair-wise qCML method exact tests with a Benjamini Hochberg false discovery rate correction greater than the threshold of P < 0.05. As we described previously, there is significant variation in gene expression between inbred C57Bl/6 <har> and mice with a mixed background below a threshold of 2.5 fold. For this reason we filtered out all genes whose differential expression was less than 2.5 fold. We also wanted to filter out genes that were expressed at such low levels that they were unlikely to impact cellular function. We restricted our list to those genes that were expressed at greater than 2 Reads per Kilobase per million reads (RPKM) in either WT or Prox1 cKO samples, a value which corresponds to approximately 1 mRNA molecule per cell. The application of these filtering criteria resulted in narrowing our list to 642 genes that were likely to impact the Prox1 cKO lens phenotype. Manthey, A. L., Lachke, S. A., FitzGerald, P.

Description
Continuous contact with self-major histocompatibility complex ligands is essential for the survival of naive CD4 T cells. We have previously shown that the resulting tonic TCR signaling also influences their fate upon activation by increasing their ability to differentiate into induced regulatory T cells. To decipher the molecular mechanisms governing this process, microarray data comparing highly (Ly-6C-) and lowly (Ly-6C+) Self-reactive naive CD4 T cells were obtained.

Description
Reprogramming of cellular metabolism plays a central role in fuelling malignant transformation, and AMPK as well as the PGC-1/ERR axis are key regulators of this process. Intersection of gene expression and binding event datasets in breast cancer cells shows that activation of AMPK significantly increases the expression of PGC-1/ERR and promotes the binding of ERR to its cognate sites. Unexpectedly, the data also reveal that ERR, in concert with PGC-1, negatively regulates the expression of several one-carbon metabolism genes resulting in substantial perturbations in purine biosynthesis. This PGC-1/ERR-mediated repression of one-carbon metabolism promotes the sensitivity of breast cancer cells and tumors to the anti-folate drug methotrexate. These data implicate the PGC-1/ERR axis as a core regulatory node of folate cycle metabolism and further suggest that activators of AMPK could be used to modulate this pathway in cancer.
