Project description:GBM samples (FFPE tissue) obtained from patients treated in clinical trials according to pre-specified clinical criteria (EORTC 26981/NCIC CE.3 pooled with the Lausanne Pilot trial, n=156).
Project description:The goal of the study was to identify a gene expression signature capable of predicting a pathological complete response following neoadjuvant anthracycline-based chemotherapy of breast cancer. The samples were taken from the FEC arm (5-fluorouracil, epirubicin, cyclophosphamide) of the EORTC 10994 trial. EORTC 10994 is a phase III clinical trial comparing FEC with ET (epirubicin, docetaxel) in patients with large operable, locally advanced or inflammatory breast cancer (www.eortc.be). Frozen biopsies were taken at randomisation. RNA was extracted from 100um thickness of 14G core needle biopsies. Adjacent sections were tested by H&E to confirm >20% tumour cell content. 200 ng total RNA per chip was amplified using the Affymetrix small sample protocol (IVT then Enzo). 102 tumours were tested on Affymetrix X3P chips. Single biopsies were tested per tumour. The CEL files were quantile normalised using rma. The clinical response measure was pathological complete response (pCR, disappearance of the tumour after chemotherapy with at most scattered invasive cells detected by histology). 102 tumors
Project description:This SuperSeries is composed of the following subset Series: GSE20680: Whole Blood Cell Gene Expression Profiling in Patients with Coronary Artery Disease from the Cathgen Registry GSE20681: Whole Blood Cell Gene Expression Profiling in Patients with Coronary Artery Disease from the PREDICT Trial Refer to individual Series
Project description:Gene expression profiling of immortalized human mesenchymal stem cells with hTERT/E6/E7 transfected MSCs. hTERT may change gene expression in MSCs. Goal was to determine the gene expressions of immortalized MSCs.
