- Affymetrix Human Genome U133 Plus 2.0 Array (hgu133plus2)
Description
We report that previously described molecular subtypes of colorectal cancer are associated with the response to therapy in patients with metastatic disease. We also identified a patient population with high FOLFIRI sensitivity, as indicated by their 2.7-fold longer overall survival when treated with FOLFIRI, as first-line regimen, instead of FOLFOX. Our results demonstrate the interest of molecular classifications to develop tailored therapies for patients with metastatic colorectal cancer.

- Sentrix Human-6 Expression BeadChip
Description
The functional consequences of missense variants in disease genes are difficult to predict. We assessed if gene expression profiles could distinguish between BRCA1 or BRCA2 pathogenic truncating and missense mutation carriers and familial breast cancer cases whose disease was not attributable to BRCA1 or BRCA2 mutations (BRCAX cases). 72 cell lines from affected women in high-risk breast-ovarian families were assayed after exposure to ionising irradiation, including 23 BRCA1 carriers, 22 BRCA2 carriers, and 27 BRCAX individuals. A subset of 10 BRCAX individuals carried rare BRCA1/2 sequence variants considered to be of low clinical significance (LCS). BRCA1 and BRCA2 mutation carriers had similar expression profiles, with some subclustering of missense mutation carriers. The majority of BRCAX individuals formed a distinct cluster, but BRCAX individuals with LCS variants had expression profiles similar to BRCA1/2 mutation carriers. Gaussian Process Classifier predicted BRCA1, BRCA2 and BRCAX status with a maximum of 62% accuracy, and prediction accuracy decreased with inclusion of BRCAX samples carrying an LCS variant, and inclusion of pathogenic missense carriers. Similarly, prediction of mutation status with gene lists derived using Support Vector Machines was good for BRCAX samples without an LCS variant (82-94%), poor for BRCAX with an LCS (40-50%), and improved for pathogenic BRCA1/2 mutation carriers when the gene list used for prediction was appropriate to mutation effect being tested (71-100%). This study indicates that mutation effect, and presence of rare variants possibly associated with a low risk of cancer, must be considered in the development of array-based assays of variant pathogenicity.

Illumina HiSeq 2000
Description
By transcriptome (RNA-Seq) analysis of PC-3 or DU145 prostate cancer cell lines over- or under-expressing NUSAP1, we determined genes that become differentially expressed upon expression changes of NUSAP1. Ingenuity Pathway Analysis revealed that the differentially expressed genes correlated with increased tumor progression and are involved in functions that include cancer, cellular movement, and cell morphology Overall design: Lentiviral infections were used to over- or under-express NUSAP1 or controls in triplicate in PC-3 or DU145 cell lines. Seventy-two or ninety-six hours after infection, total RNA was extracted and purified. The sequencing libraries were prepared with the TruSeq RNA Sample Preparation Kit v2 (Illumina) or TruSeq Stranded mRNA Sample Preparation Kit (Illumina) as directed by the manufacturer’s protocol. Pooled libraries were run on a Hiseq 2000 Sequencing System (Illumina) with 101 base pair single-end reads.
