Affymetrix Human Genome U133 Plus 2.0 Array (hgu133plus2)
Description
Day-to-day variability in microarray experiments is a recognized source of variation that can impede the analysis of large microarray studies where samples are processed on different days. In this study, we have applied an algorithm, called D2Dsum, which is based on a log-linear fixed effect model to cope with this kind of issues on a data set of 45 microarrays.

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.
Publication Title
Transcriptional analysis of the Aurora inhibitor Danusertib leading to biomarker identification in TP53 wild type cells.

- Affymetrix Human Genome U133 Plus 2.0 Array (hgu133plus2)
Description
Microarrays have been widely used for the analysis of gene expression and several commercial platforms are available. The combined use of multiple platforms can overcome the inherent biases of each approach, and may represent an alternative that is complementary to RT-PCR for identification of the more robust changes in gene expression profiles.
Publication Title
Cross platform microarray analysis for robust identification of differentially expressed genes.

Description
The development of cytostatic-drug resistance renders chemotherapy ineffective in treating ovarian cancer, the most lethal gynaecological malignancy. In many cases, it is difficult to explain the development of drug resistance based on the expression patterns of genes known to be involved in this process. Microarray-based assays can provide information about new genes that are involved in the resistance to cytostatic drugs. This report describes alterations in the level of expression of genes in cisplatin- (CisPt), doxorubicin- (Dox), topotecan- (Top), and paclitaxel- (Pac) resistant variants of W1 and A2780 ovarian cancer cell lines. These drug-resistant variants of the W1 and A2780 cell lines were generated through the stepwise selection of cells tolerant of exposure to the indicated drugs at incrementally increased concentrations. Affymetrix GeneChip Human Genome Array Strips were used for hybridization assays. The genes with significantly altered expression levels (upregulated by more than fivefold or downregulated by less than fivefold relative to the level in the parental line) in the drug-resistant sublines were selected and were filtered using volcano plotting.
