Affymetrix Human Gene 1.0 ST Array (hugene10st)
Description
In response to stress, the p53 tumor suppressor induces arrest or apoptosis by transcriptionally regulating genes that mediate these processes. It has been proposed that the levels of p53 can influence the choice between these different outcomes, but the mechanisms involved are not clear. To gain mechanistic understanding of this p53-dependent cell fate decision, we generated a p53 inducible system that allowed tight regulation of p53 expression in human mammary epithelial cells.

Description
The purpose of this study was to analyze the genomic signatures and profiles of skin from ichthyosis (various subtypes) vs. healthy patients. The analysis strategy was to study differentially expressed genes common to the ichthyosis shared phenotype, as well as individual ichthyosis subtypes, and compare and contrast to the genomic profiles of atopic dermatitis and psoriasis.

Description
Ensuring cooperation among formerly autonomous cells has been a central challenge in the evolution of multicellular organisms. One solution is monoclonality, but this option does not eliminate genetic and epigenetic variability, leaving room for exploitative behavior. We therefore hypothesized that embryonic development must be protected by robust regulatory mechanisms that prevent aberrant clones from superseding wild-type cells. Using a genome-wide screen in murine induced pluripotent stem cells, we identified a network of genes (centered on p53, topoisomerase 1, and olfactory receptors) whose downregulation caused the cells to replace wild-type cells, both in vitro and in the mouse embryowithout perturbing normal development. These genes thus appear to fulfill an unexpected role in fostering cell cooperation.

Description
Chronic injury in kidney transplants remains a major cause of graft loss. The aim of this study was to identify a predictive gene set capable of classifying renal grafts at risk for progressive injury due to fibrosis.The Genomics of Chronic Allograft Rejection (GoCAR) study is a prospective, multicenter study. Biopsies obtained prospectively 3 months after transplantation from renal allograft recipients (n=159) with stable renal function were analyzed for gene expression by microarray. Genes were sought which correlated with subsequent 12-month Chronic Allograft Damage Index (CADI) but neither CADI in the 3 month biopsy nor other histological or clinical parameters.

Description
Gene expression profiles of 75 tissue samples were analyzed representing the stepwise carcinogenic process from pre-neoplastic lesions (cirrhosis and dysplasia) to HCC, including four neoplastic stages (very early HCC to metastatic tumors) from patients with HCV infection. Gene signatures that accurately reflect the pathological progression of disease at each stage were identified and potential molecular markers for early diagnosis uncovered. Pathway analysis revealed dysregulation of the Notch and Toll-like receptor pathways in cirrhosis, followed by deregulation of several components of the Jak/STAT pathway in early carcinogenesis, then up-regulation of genes involved in DNA replication and repair and cell cycle in late cancerous stages.

Description
T-cell acute lymphoblastic leukemia (T-ALL) and T-cell lymphoblastic lymphoma (T-LL) and are often thought to represent a spectrum of a single disease. The malignant cells in T-ALL and T-LL are morphologically indistinguishable, and they share the expression of common cell surface antigens and cytogenetic characteristics. However, despite these similarities, differences in the predominant sites of disease in T-ALL and T-LL are observed. To determine if underlying biological distinctions may potentially contribute to some of these differences, we analyzed the global gene expression profiles of malignant T-cell precursors in ten T-ALL and nine T-LL using DNA arrays. Ten additional B-precursor ALL bone marrow samples, were used in a separate analysis.

Description
Early epigenetic changes and DNA damage do not predict clinical response in an overlapping schedule of 5-azacytidine and entinostat in patients with myeloid malignancies. The patients with MDS, chronic myelomonocytic leukemia (CMMoL), and high risk AML were treated with sequential administration of methylation inhibitor drugs (5AC and entinostat). To study gene expresion regulation in treated patients, microarray analysis was done on RNA samples extracted from CD34+ cells from 18 patients before and 15 days after treatment using Affymetrix U133Plus2.0.
