Description
An RNA-seq study of altered gene expression and mutations in Ara-C resistant acute myeloid leukemia murine cell lines. The analysis of the RNA-seq data led to the identification of a large deletion within the Dck coding sequence of the B117H cell line, which produced an alternatively processed form of Dck mRNA. The RNA-seq analysis also identified the presence of an insertion mutation in Dck in the B140H cell line. The RNA-seq analysis also identified a number of significant expression changes which did not appear in a previous microarray analysis (GSE18322), as well as identified other mutations which may be contributing to Ara-C resistance. Overall design: Two highly Ara-C resistant cell lines, B117H and B140H were derived from Ara-C sensitive parental cell lines, B117P and B140P. Variations in gene expression as well identification of acquired mutations between these Ara-C resistant/sensitive sets were studied using various RNA-seq analysis tools.

Description
Three normal human osteoblast samples, acquired from PromoCell, were used as controls to compare to RNA-seq data from prepublished osteosarcoma samples (submitted to the European Bioinformatics Institute; EGAS00001000263) for the purpose of evaluating expression levels of genes identified as common insertions sites in a Sleeping Beauty screen of osteosarcomas in mice. Overall design: Three normal human osteoblast samples (pellet form in RNAlater) were acquired from PromoCell (Heidelberg, Germany), and RNA was isolated from them immediately upon receipt.

Affymetrix Human Genome U133 Plus 2.0 Array (hgu133plus2)
Description
Average life expectancy for patients with metastatic melanoma is less than 6 months, and only a handful of treatment options are available. If the disease can be stopped before it spreads to other organs, life expectancy is greatly increased. The goal of this project is to identify possible regulators of melanoma metastasis by determining genes whose expression is modulated when the cells are grown in contact with endothelial cells. Identification of genes involved in this cell-cell communication could have therapeutic implications.

Description
Analysis of 104 breast cancer biopsies (removed prior to any treatment with tamoxifen or chemotherapeutic agents) from patients aged between 31 years and 89 years at the time of diagnosis (mean age = 58 years). Twenty were less than 50 years and seventy-seven women were 50 years, or older, at diagnosis. The size of the tumours ranged between 0.6 cm and 8.0 cm (mean = 2.79 cm). Eighteen tumours were T1 (<2 cm) in maximal dimension; 83 were T2 (25 cm) and 3 tumours were T3 (>5 cm). Eighty-two were invasive ductal carcinoma, 17 were invasive lobular and five were tumours of special type (two tubular and three mucinous). Eleven tumours were grade 1; 40 were grade 2; and 53 were grade 3. Sixty-seven tumours were oestrogen receptor (ER) positive and 34 were ER negative (ER status was determined by Enzyme Immuno-Assay (EIA); a positive result was defined as more than 200 fmol/g protein). ER status was not available for 3 patients. Forty-five tumours had no axillary metastases and 59 tumours had metastasised to axillary lymph nodes. Sixty-nine women were treated with post-operative tamoxifen; 26 did not receive tamoxifen. Fifty patients were treated with adjuvant systemic chemotherapy (CMF +/ adriamycin); 45 patients did not receive chemotherapy. Details regarding tamoxifen and systemic chemotherapy were not available for 9 patients. Maximal follow-up was 3,026 days with a mean follow-up of 1,887 days.

Description
Hepatic iron overload is a risk factor for progression of hepatocellular carcinoma (HCC), although the molecular mechanisms underlying this association have remained unclear. We now show that the iron-sensing ubiquitin ligase FBXL5 is previously unrecognized oncosuppressor in liver carcinogenesis in mice. Hepatocellular iron overload evoked by FBXL5 ablation gives rise to oxidative stress, tissue damage, inflammation and compensatory proliferation in hepatocytes and to consequent promotion of liver carcinogenesis induced by exposure to a chemical carcinogen. The tumor-promoting effect of FBXL5 deficiency in the liver is also operative in a model of virus-induced HCC. FBXL5-deficient mice thus constitute the first genetically engineered mouse model of liver carcinogenesis induced by iron overload. Dysregulation of FBXL5-mediated cellular iron homeostasis was also found to be associated with poor prognosis in human HCC, implicating FBXL5 plays a significant role in defense against hepatocarcinogenesis. Overall design: Total RNA was extracted from the nontumor and tumor tissue of an Alb-Cre/Fbxl5F/F male mouse (nontumor, n = 5; tumor, n = 5) or two littermate control Fbxl5F/F mice (nontumor, n = 6; tumor, n = 6) at 45 weeks of age.
