- Affymetrix Rat Genome 230 2.0 Array (rat2302)
Description
Male Sprague-Dawley rats [Crl:CD(SD)IGS BR], weighing ~250 g at study initiation were obtained from Charles River Laboratories, Inc. (Wilmington, MA). Rats were housed singly in ventilated, stainless steel, wire-bottom hanging cages and fed non-certified Rodent Chow (Harlan Labs, Madison, WI) and water ad libitum and acclimated for at least 5 days after arrival. Rats were randomly assigned to various treatment groups (3 rats/group) and were dosed once daily by oral gavage with vehicle (0.2% hydroxypropylmethylcellulose at a dose volume of 10 ml/kg) or with 30, 100, or 200 mg/kg of A-998679. All rats were fasted overnight after their last dose, weighed and sacrificed under isoflurane anesthesia. Liver and small intestine (jejunum) were flash frozen in liquid nitrogen and stored at 80C until processing for gene expression profiling on the Affymetrix platform.

- Affymetrix Mouse Gene 2.0 ST Array (mogene20st)
Description
CD8+ T cells are pre-programmed for cytotoxic differentiation. However, a subset of effector CD8+ T cells (Tc17) produce IL-17 and fail to express cytotoxic genes. Here, we show that the transcription factors directing IL-17 production inhibit cytotoxicity despite persistent Runx3 expression. Cytotoxic gene repression did not require the transcription factor Thpok. We further show that STAT3 restrained cytotoxic gene expression in CD8+ T cells and that RORgt represses cytotoxic genes by inhibiting the functions but not the expression of the cytotoxic transcription factors T-bet and Eomesodermin. Thus, the transcriptional circuitry directing IL-17 expression inhibits cytotoxic functions.

- Affymetrix Human Genome U219 Array (hgu219)
Description
The identification of new agents that may modulate the progression of cancer cell growth is of great interest. In this regard, dietary agents can be utilized to identify molecular targets to be used as part of a chemopreventive strategy. Walnuts contain several bioactive compounds, including pedunculagin, a polyphenol metabolized by microbiota to form urolithins, namely urolithin A (UA). We performed a genomic analysis to study the effect of UA on androgen-dependent LNCaP prostate adenocarcinoma cells. Cells were incubated with 40M UA for 24 hours, then, RNA was extracted. RNA samples were processed in the automated Biomek FX System (Beckman Coulter), where aRNA was produced, and labeled with Biotin, purified , fragmented and hybridized onto HG U219-24 Array, using the GeneChip HT 3IVT Express Kit . Afterwards, the GeneTitan Multi-Channel (MC) Instrument (Affymetrix) was used to hybridize, wash , stain , and scan the arrays. Microarray results were analyzed using the GeneSpring GX v13.0 software.

Description
The LEDGF transcript from the PSIP1 gene was knocked down in Jurkat cells using RNAi technology. The resulting Jurkat-derived cell line (Jurkat-siJK2) was compared to a control cell line (wild type Jurkat) using microarray analysis. Genes identified as being modulated by LEDGF were preferential targets of HIV integration.
