Affymetrix Human Genome U133 Plus 2.0 Array (hgu133plus2)
Description
Patients with palliative SCCHN were treated with figitumumab, an IGF-1R inhibitor. This receptor plays an important role in cell growth, proliferation and differentiation and is often overexpressed in SCCHN. No significant clinical activity was observed in our study
Publication Title
Phase II study of figitumumab in patients with recurrent and/or metastatic squamous cell carcinoma of the head and neck: clinical activity and molecular response (GORTEC 2008-02).

Description
Global transcription machinery engineering (gTME) is an approach for reprogramming gene transcription to elicit cellular phenotypes important for technological applications. Here we show the application of gTME to Saccharomyces cerevisiae for improved glucose/ethanol tolerance, a key trait for many biofuels programs. Mutagenesis of the transcription factor Spt15p and selection led to dominant mutations that conferred increased tolerance and more efficient glucose conversion to ethanol. The desired phenotype results from the combined effect of three separate mutations in the SPT15 gene [serine substituted for phenylalanine (Phe177Ser) and, similarly, Tyr195His, and Lys218Arg]. Thus, gTME can provide a route to complex phenotypes that are not readily accessible by traditional methods.

Description
In this study we used microarrays to examine relative genes expression within the aorta of ApoE-/- infused with angiotensin II in relation to aneurysm formation. Infusion of angiotensin II induces aortic dilatation particularly of the suprarenal aorta in ApoE-/- mice. Based on studies carried out in our and other laboratories the response to angiotensin II is variable, with some mice developing large aneurysms but other animals appearing resistant to aneurysm formation with aortic diameters similar to that of saline controls. We compared RNA expression from whole aortas of 17 week old male ApoE-/- mice exposed to angiotensin II (1.44 g/kg/min) for 4 weeks where there was clear evidence of aortic aneurysm formation (n=5) with that of mice failing to develop aneurysms (n=7) and those exposed to saline infusion (n=6). AAA was defined as diameter of suprarenal aorta greated than 1.5mm measured on photographs of aortas at necroscopy.

Description
Vitis vinifera endogenous small RNAs Overall design: Size fractionated small RNA from total RNA extracts of Vitis vinifera leaves, inflorescences, tendrils and small berries were ligated to adapters, purified again and reverse transcribed. After PCR amplification the sample was subjected to Solexa/Illumina high throughput pyrosequencing. Please see www.illumina.com for details of the sequencing technology.

Description
Vitis vinifera RNA degradome Overall design: Isolated polyadenylated RNA from total RNA extracts of Vitis vinifera leaves, were ligated to 5'-adapter that include san MmeI recognition site. The ligated products were purified again, reverse transcribed and cleaved with MmeI. The 5' fragments were purified from gel and to a 3'- dsDNA adapter and PCR amplified. After PCR amplification the sample was subjected to Solexa/Illumina high throughput pyrosequencing. Please see www.illumina.com for details of the sequencing technology.

- Affymetrix Human Exon 1.0 ST Array [probe set (exon) version (huex10st)
Description
Misregulated alternative splicing appears to be a major factor in the pathogenesis of myotonic dystrophy. The present study was done to further explore alternative splicing in this condition by doing exon-level analysis of mRNA from skeletal muscle of 8 subjects with type 1 myotonic dystrophy, 7 subjects with type 2 myotonic dystrophy, 8 disease controls (subjects with facioscapulohumeral muscular dystrophy), and 8 healthy controls . The ratios of signals from the various exons of a gene provided an index of altered exon inclusion/exclusion that was independent of the overall expression of that gene. There were numerous transcripts for which there was evidence of abnormal alternative splicing in subjects with myotonic dystrophy. For many of these transcripts, the abnormal splicing was confirmed by an independent RT-PCR approach.
