Affymetrix Mouse Gene 2.0 ST Array (mogene20st)
Description
The NAT enzymes are polymorphic xenobiotic metabolizing enzymes that catalyze the transfer of an acetyl moiety from acetyl coenzyme A (acetyl-CoA) to the nitrogen or oxygen atom of primary arylamines, hydrazines, and their N-hydroxylated metabolites. NATs therefore play an important role in the detoxification and/or activation of arylamine drugs and carcinogens. The involvement of acetyl-CoA in energy metabolism suggests that there may be relationships between NAT activity and energy metabolism. Previous studies have suggested a role for NAT2 in insulin sensitivity that is exacerbated on high fat diet, using Nat1 knockout mice. To study mice with no NAT activity at all, we used a Nat1/Nat2 double-KO model, with animals fed either a regular chow or high fat/high sugar diet for 12 weeks. Analysis of basal parameters suggested a decrease in fatty-acid oxidation and hepatic gluconeogenesis. To further evaluate the cause of this, RNA was isolated and processed using Affymetrix Mouse Gene 2.0 microarrays.

- Affymetrix Human Genome U133 Plus 2.0 Array (hgu133plus2)
Description
Canonical Hedgehog (Hh) signaling regulates the expression of genes that are critical to the patterning and development of a variety of organ systems. In adult, both ligand-dependent and ligand-independent Hh pathway activation are known to promote tumorigenesis. Recent studies have shown that in tumors promoted by Hh ligand, activation occurs within the stromal microenvironment (Yauch et al., 2009). In situ hybridization of the pathway target gene, Ptch1, shows that signaling is located at stromal perivascular fibroblast-like cells in xenograft tumor sections derived from Hh-expressing colorectal cancer cell lines.

Canonical hedgehog signaling augments tumor angiogenesis by induction of VEGF-A in stromal perivascular cells.

Description
The Bmi1 Polycomb protein is involved in the epigenetic repressive control of self renewal and survival of cancer initiating cells. In Chronic Myeloid Leukemia (CML), bmi1 expression increases gradually as the disease progresses from a chronic latent phase to a deadly blast crisis. We developped an inducible shRNA system to silence Bmi1 in the human K562 chronic myeloid leukemia (CML) cell line in order to identify new Bmi1-target genes.

Description
Most cancer deaths are caused by metastases, which are the end-results of circulating tumor cells (CTC) that detach from the cancer primary and succeed to survive in distant organs. The aim of the present study was to develop a gene signature of CTC and to assess its prognostic relevance after surgery for pancreatic ductaladenocarcinoma (PDAC).

- Affymetrix Chicken Genome Array (chicken)
Description
Domestic broiler chickens rapidly accumulate adipose tissue due to intensive genetic selection for rapid growth and are naturally hyperglycemic and insulin resistant, making them an attractive addition to the suite of rodent models used for studies of obesity and type 2 diabetes in humans. Furthermore, chicken adipose tissue is considered as poorly sensitive to insulin and lipolysis is under glucagon control. Excessive fat accumulation is also an economic and environmental concern for the broiler industry due to the loss of feed efficiency and excessive nitrogen wasting, as well as a negative trait for consumers who are increasingly conscious of dietary fat intake. Understanding the control of avian adipose tissue metabolism would both enhance the utility of chicken as a model organism for human obesity and insulin resistance and highlight new approaches to reduce fat deposition in commercial chickens.
Publication Title
Transcriptomic and metabolomic profiling of chicken adipose tissue in response to insulin neutralization and fasting.
