- Affymetrix Human Genome U133 Plus 2.0 Array (hgu133plus2)
Description
To identify patterns of gene expression that correlate with response to treatment with either melphalan or temozolomide we measured both gene expression using microarray genechips and response to drug using a standard in vitro cell proliferation assay. Senstivity to melphalan was measured 48hrs after drug treatment while sensitivity to temozolomide was measured 12 days after drug treatment.

Genomic and molecular profiling predicts response to temozolomide in melanoma.

Description
Pericytes are integral components of the tissue vasculature and have essential functions in tumour angiogenesis. Endosialin (CD248) is a type I transmembrane glycoprotein highly expressed on pericytes in the tumour vasculature of most solid tumours, however it is low or negligibly expressed on normal tissue pericytes. Experiments using wild-type and endosialin-knockout mice has revealed that stromal endosialin expression facilitates intravasation of tumor cells from the primary tumor into the circulation, thereby promoting metastatic dissemination.

Description
Purpose: Gene expression signatures developed to measure the activity of oncogenic signaling pathways have been used to dissect the heterogeneity of tumor samples and to predict sensitivity to various cancer drugs that target components of the relevant pathways, thus potentially identifying therapeutic options for subgroups of patients. To facilitate broad use, including in a clinical setting, the ability to generate data from formalin-fixed, paraffin-embedded (FFPE) tissues is essential. Experimental Design: Patterns of pathway activity in matched fresh-frozen and FFPE xenograft tumor samples were generated using the MessageAmp Premier methodology in combination with assays using Affymetrix arrays. Results generated were compared with those obtained from fresh-frozen samples using a standard Affymetrix assay. In addition, gene expression data from patient matched fresh-frozen and FFPE melanomas were also utilized to evaluate the consistency of predictions of oncogenic signaling pathway status. Results: Significant correlation of pathway activity predictions was observed between paired fresh-frozen and FFPE xenograft tumor samples. In addition, significant concordance of pathway activity predictions was also observed between patient matched fresh-frozen and FFPE melanomas. Conclusion: Reliable and consistent predictions of oncogenic pathway activities can be obtained from FFPE tumor tissue samples. The ability to reliably utilize FFPE patient tumor tissue samples for genomic analyses will lead to a better understanding of the biology of disease progression and, in the clinical setting, will provide tools to guide the choice of therapeutics to those most likely to be effective in treating a patients disease.

Description
Innate memory phenotype (IMP) CD8+ T cells are non-conventional T cells exhibiting features of innate immune cells, and are significantly increased in the absence of non-receptor tyrosine kinase ITK. Their developmental path and function are not clear, particularly whether they can contribute to antigen specific responses. We found that WT bone marrow gives rise to IMP CD8+ T cells in irradiated MHCI-/- recipients, resembling those in Itk-/- mice determined by expression of surface markers. However, CD8+ T cells share similar expression of memory markers.
Publication Title
Cutting edge: innate memory CD8+ T cells are distinct from homeostatic expanded CD8+ T cells and rapidly respond to primary antigenic stimuli.

HLX was found as a VEGF-A induced gene in HUVEC (B.Schweighofer, submitted). In order to detect genes regulated by HLX HUVEC were infected by recombinant adenovirus expressing HLX for 4, 8, 16 and 32h. RNA was isolated and subjected to microarray analysis using Affymetrix microarray.
Publication Title
The VEGF-regulated transcription factor HLX controls the expression of guidance cues and negatively regulates sprouting of endothelial cells.
