Affymetrix Human Genome U133 Plus 2.0 Array (hgu133plus2)
Description
ARC (NSC 188491, SMA-491), 4-amino-6-hydrazino-7-beta-d-ribofuranosyl-7H-pyrrolo-(2,3-d)-pyrimidine-5-carboxamide, is a nucleoside analog with profound in vitro anti-cancer activity. First identified in a high-throughput screen for inhibitors of p21 mRNA expression, subsequent experiments showed that ARC also repressed expression of hdm2 and survivin, leading to its classification as a global inhibitor of transcription 1. The following Hu U133 plus 2.0 arrays represent single time point (24 hour) gene expression analysis of transcripts altered by ARC treatment. Arrays for the other compounds (sangivamycin and doxorubicin) are included as comparators.
Publication Title
ARC (NSC 188491) has identical activity to Sangivamycin (NSC 65346) including inhibition of both P-TEFb and PKC.

Description
Development of LNA gapmers, antisense oligonucleotides used for efficient inhibition of target RNA expression, is limited by non-target mediated hepatotoxicity issues. In the present study, we investigated hepatic transcription profiles of mice receiving non-toxic and toxic LNA gapmers after a single and repeat administration.

Description
Xenograft models remain a cornerstone technology in the development of anti-cancer agents. The ability of immunocompromised rodents to support the growth of human tumors provides an invaluable transition between in vitro testing and clinical trials. Therefore, approaches to improve model selection are required. In this study, cDNA microarray data was generated for a collection of xenograft models at in vivo passages 1, 4 and 10 (P1, P4 and P10) along with originating cell lines (P0). These data can be mined to determine transcript expression 1) relative to other models 2) with successive in vivo passage and 3) during the in vitro (P0) to in vivo (P1) transition.

- Affymetrix Human Genome U133 Plus 2.0 Array (hgu133plus2)
Description
Transcriptomic studies of human tumor xenografts are complicated by the presence of murine cellular mRNA. As such, it is useful to know the extent to which mouse mRNA cross-hybridizes to any given array platform. In this study, murine cDNA samples from diverse sources were hybridized to Affymetrix Human Genome U133 Plus 2.0 Arrays. In this regard it is possible to identify specific probes that are potential targets of cross-species interference.

Description
Germline BRCA1 or BRCA2 mutations (mtBRCA1 and mtBRCA2) dramatically increase risk for high-grade serous ovarian cancer (HGSOC), the most commonly diagnosed histotype. Other risk factors for this cancer, which originates primarily in the distal fallopian tube epithelium (FTE), implicate ovulation. To test whether mtBRCA1 or mtBRCA2 FTE cells respond differently to peri-ovulatory follicular fluid (FF) exposure than control patient FTE, gene expression profiles from primary FTE cultures were compared at baseline, 24h after FF exposure, and 24h after FF replacement with culture medium. Hierarchical clustering revealed both FF exposure and BRCA mutation status affect gene expression, with BRCA1 mutation having the greatest impact. Analysis revealed increased NFB and EGFR signaling at baseline, with increased interferon signaling after recovery from FF exposure in mtBRCA1 samples. Inhibition of EGFR signaling and ISGylation by increased BRCA1 expression was verified in an immortalized FTE cell line, OE-E6/E7, stably transfected with BRCA1. Suppression of ISG15 and ISGylated protein levels by BRCA1 expression was found to be mediated by decreased NFB signaling and was transiently suppressed by FF exposure. This study demonstrates increased NFB signaling associated with decreased BRCA1 expression resulting in increased ISG15 and ISGylation following FF exposure, which could represent potential targets for chemoprevention.

Description
ETS1 and RAS/ERK regulate a common gene expression program in establishing enviroment suitable for prostate cancer cell migration. Overall design: mRNA profiles of luciferase knockdown (WT), ETS1 knockdown, and U0126 treated DU145 cells were generated using deep sequencing, in triplicate, using Illumina HiSeq. Knockdowns were stable shRNA expression from a lentiviral construct selected with puromycin.

Description
We measured gene expression of D. melanogaster female heads and abdomens after mating with males from six populations evolved under either enforced monogamy (no male-male competition, 3 populations) or sustained polygamy (intense male-male competition, 3 populations). Overall design: Three samples of virgin female heads and six samples of mated female heads (one each per male evolved population, of which there are three monogamous and three polygamous), for nine libraries. Also, three samples of virgin female abdomens and six samples of mated female abdomens (one each per male evolved population, of which there are three monogamous and three polygamous), for nine libraries. In total, eighteen libraries sequenced in 8 lanes.
