Affymetrix Human Gene 2.1 ST Array (hugene21st)
Description
Purpose: Black/African American (AA) women are twice as likely to be diagnosed with triple negative breast cancer (TNBC) compared to whites, an aggressive breast cancer subtype associated with poor prognosis. There are no routinely used targeted clinical therapies for TNBC; thus there is a clear need to identify prognostic markers and potential therapeutic targets. Methods: We evaluated expression of 27,016 genes in 155 treatment-naïve TN tumors from AA women in Detroit. Associations with survival were evaluated using Cox proportional hazards models adjusting for stage and age at diagnosis, and p-values were corrected using a false discovery rate. Our validation sample consisted of 158 TN tumors (54 AA) from The Cancer Genome Atlas (TCGA). Meta-analyses were performed to obtain summary estimates by combining TCGA and Detroit AA cohort results. Results: In the Detroit AA cohort, CLCA2 [Hazard ratio (HR)=1.56, 95% confidence interval (CI) 1.31-1.86, nominal p=5.1x10-7, FDR p=0.014], SPIC [HR=1.47, 95%CI 1.26-1.73, nominal p=1.8x10-6, FDR p=0.022], and MIR4311 [HR=1.57, 95% CI 1.31-1.92, nominal p=2.5x10-5, FDR p=0.022] expression were associated with overall survival. Further adjustment for treatment and breast cancer specific survival analysis did not substantially alter effect estimates. Meta-analysis with TCGA data showed that CLCA2 and SPIC were associated with overall survival for TNBC among AA women. Conclusions: We identified three potential prognostic markers for TNBC in AA women, for which SPIC may be an AA-specific prognostic marker.

Description
This is the expression dataset for two studies: 1) Characterization of visceral and subcutaneous adipose tissue transcriptome and biological pathways in pregnant and non-pregnant women: Evidence for pregnancy-related regional-specific differences in adipose tissue and 2) Characterization of visceral and subcutaneous adipose tissue transcriptome in pregnant women with and without spontaneous labor at term: Implication of alternative splicing in the metabolic adaptations of adipose tissue to parturition.

- Illumina humanRef-8 v2.0 expression beadchip
Description
Numerous studies have shown the potential of spermatozoal RNAs to delineate failures of spermatogenic pathways in infertile samples. However, the RNA contribution of normal fertile samples still needs to be established in relation to transcripts consistently present in human spermatozoa. We report here the spermatozoal transcript profiles characteristic of 24 normally fertile individuals. RNA was extracted from the purified sperm cells of ejaculate and hybridized to Illumina Human-8 BeadChip Microarrays

- Affymetrix Rat Gene 2.0 ST Array (ragene20st)
Description
Complete global brain ischemia (CGBI) and reperfusion occur following resuscitation from cardiac arrest. Different brain neurons are selectively vulnerable to CGBI: pyramidal neurons of hippocampal CA3 survive 10 min CGBI but those of CA1 die at 3 days following 10 min CGBI. CA3 neurons are expected to have more robust stress responses and repair responses than CA1 neurons.

Affymetrix Human Genome U133 Plus 2.0 Array (hgu133plus2)
Description
Normal human spermatogenesis concludes with the formation of large numbers of morphologically well developed spermatozoa. While transcriptionally quiescent these cells carry an RNA payload that reflects the final spermiogenic phase of transcription. We report here the spermatozoal transcript profiles characteristic of normally fertile individuals and infertile males suffering from a consistent and severe teratozoospermia in which under 4% of spermatozoa are morphologically normal. RNA was extracted from the purified sperm cells of ejaculate and hybridized to Affymetrix U133 (v2) Microarrays.
