Description
The use of Affymetrix U133 2.0 Plus chips on FFPE samples when coupled with a qPCR-based sample pre-assessment step, yielded satisfactory results from the point of view of biological reliability. When compared with the Illumina DASL WG platform, specifically designed for degraded RNA, the data generated with the Affymetrix platform showed a wider interquartile range (IQR 1.32 vs 0.57, p<2.2x10-16) suggesting a superior discriminatory power within samples as indicated by the good agreement with the immunohistiochemically derived ER status.

Illumina HiSeq 2500
Description
Purpose: To identify the impact of thermoneutral housing as opposed to standard housing on gene expression profiles in the mouse peripheral blood mononuclear cells (PBMCs), focusing on proinflammatory immune responses and high-fat diet induced non-alcoholic fatty liver disease pathogenesis. Methods: Expression profiles from PBMCs collected from C57Bl6 mice fed chow or high-fat diet for 8 weeks, following 2 weeks at either standard or thermoneutral housing conditions. Sequencing was performed in duplicate, the Illumina HiSeq 2500. Transcripts that passed quality filters were analyzed at the gene level, using Strand NGS for accurate alignment and quantification. Results: We mapped approximately 20million reads per sample to the mm10 genome using annotations produced by Ensembl, which represented 36186 transcripts. Approximately 14000 genes exhibited reasonable expression in at least one experimental condition. The primary focus was the effect of housing temperature while holding diet consistent (i.e. thermoneutral vs standard, both on high-rat diet), where ~2700 genes exhibited differential regulation. Conclusions: We present the transcriptomic profile of PBMCs from mice fed chow of high-fat diets, following either standard or thermoneutral housing. We obseve an augmented proinflammatory immune response. Overall design: PBMC expression profiles were characterized following eight weeks of chow or high-fat diet, following two weeks of standard or thermoneutral housing.

Description
Treatment with Aurora inhibitors has been shown to induce diverse biological responses in different tumor cell lines, in part depending on their p53 status. To characterize at the transcriptional level the effects of Danusertib we analyzed by microarray different tumor cell lines, with WT or mutant p53 status, that showed differential cell cycle response upon drug treatment.

Description
Dendritic cells (DCs) are professional antigen-presenting cells whose activity is intrinsically linked to the microenvironment. Hypoxia is a condition of low oxygen tension occurring in inflammatory tissues that creates a special microenvironment conditioning cell physiology. We studied the effects of hypoxia on the differentiation of human monocytes into DCs. Immature DCs were differentiated in vitro from human monocytes under normoxic (iDCs) or hypoxic (Hi-DCs) conditions and the gene expression profile was determined. Hi-DCs expressed novel hypoxia-inducible genes and were characterized by up-regulation of pathways associated with cell movement/migration.

Hypoxia is a condition of low oxygen tension occurring in inflammatory tissues that creates a special microenvironment conditioning cell physiology. We studied the effects of hypoxia on the differentiation of human monocytes into DCs and maturation into mature DCs. Mature DCs were differentiated in vitro from human monocytes under normoxic or hypoxic conditions and the gene expression profile was determined.

Description
Early-passage (<10 passages) cultures of melanoma cells from metastatic lymph node lesions and normal adult melanocytes explanted in parallel from the adjacent, non-involved skin of 5 patients were compared by cDNA arrays. Differences between normal and neoplastic counterparts were then assessed upon adjustment for individual factors.
