Affymetrix Human Genome U133 Plus 2.0 Array (hgu133plus2)
Description
Gene transfer vectors based on gamma-retroviruses target actively transcribing genes indicating that the cellular gene expression profile can be predictive of their integration pattern. Therefore, different culture conditions leading to different transcriptional activity may translate into differences in the profile of targeted genes in cells transduced with these vectors. Recent data from two gene therapy trials for SCID-X1 conducted in France and the UK suggested that small differences between in vitro stimulation conditions could explain the disparity in the frequency of common integrations sites observed in the two studies.

Description
These datasets describe a melanocyte specific, HIF1A-Dependent / Hypoxia-Responsive gene expression signature defined by the regulation of genes critical to metabolism, chromatin and transcriptional regulation, vascularization and cellular invasivness. These genes provide lineage specific targets for refinement of diagnostic markers associated with primary melanoma tumor metastatic potential, and also provides novel molecular targets for therapeutic strategies targeting metastatic disease progression.

Description
AAV gene therapy has recently been approved for clinical use and shown to be efficacious and safe in a growing number of clinical trials. However, the safety of AAV as a gene therapy has been challenged by a few studies that documented hepatocellular carcinoma (HCC) after AAV gene delivery in mice. The association between AAV and HCC has been difficult to reconcile and is the subject of intense debate because numerous AAV studies have not reported toxicity. Here, we report a comprehensive study of HCC in a large number of mice following therapeutic AAV gene delivery. Using a sensitive high-throughput integration site-capture technique and global expressional analysis, we found that AAV integration into the Rian locus and the over-expression of a proximal gene, Rtl1, were associated with HCC. In addition, we identify a number of genes with differential expression that maybe useful in the study, diagnosis and treatment of HCC. We demonstrate that AAV vector dose, enhancer-promoter selection, and the timing of gene delivery are the defining factors in AAV-mediated insertional mutagenesis. Our results help explain the AAV-mediated genotoxicity previously observed and have important implications for the design of both safer AAV vectors and gene therapy studies.

Description
An animals ability to cope with or succumb to deleterious effects of chronic psychological stress may be rooted in the brains immune responses manifested in microglial activity. Mice subjected to chronic social defeat (CSD) were categorized as susceptible (CSD-S) or resilient (CSD-R) based on behavioral phenotyping, and their microglial RNAs were isolated and analyzed by global gene expression microarrays. Microglia transcriptome from CSD-S mice was enriched for pathways that describe phases of CNS healing to sterile injury including, inflammation, oxidative stress, debris clearance, and wound resolution. Histochemical experiments confirmed the array predictions: CSD-S microglia showed elevated phagocytosis and oxidative stress, and the brains of CSD-S but not CSD-R or HC mice showed vascular leakage of intravenously injected fluorescent tracers. The results suggest that the inflammatory profile of CSD-S microglia may be precipitated by leakage of blood-born substances into brain parenchyma. We hypothesize that these CNS-centric responses contribute to the stress-susceptible behavioral phenotype.

Description
The resident skin microbiota plays a fundamental role in the control of skin physiology and growing evidence support the idea that, at this barrier site, both immunity and inflammatory processes are controlled by skin resident microbiota. However, how defined skin microbes influence the skin immune system under both steady state conditions and inflammatory settings remains poorly understood. Obesity has been linked to increased prevalence of skin inflammatory disorders.
