Project description:A cell line (MFD-1) was derived from a 55-year old male with oesophageal adenocarcinoma. Using different sources of genetic material from normal and tumour tissue surgically resected, peripheral blood and the derived cell line a high concordance of genotypes calls across the whole genome confirms MFD-1 was derived from parent tumour. The SNP6 array contained 906,000 probes for the genotyping of SNPs and 946,000 probes for the genotyping of non-polymorphic copy number. Affymetrix CEL files were analysed using the tool PICNIC2 (predicting absolute allele copy number variation with microarray cancer data).
Project description:Obesity is linked to increased mortality from many cancer types, and oesophageal adenocarcinoma displays one of the strongest epidemiological associations. The aim of this study was to dissect molecular pathways linking obesity with oesophageal adenocarcinoma and to determine if obesity is linked to increased aggressiveness of this disease. Affymetrix microarrays were used to identify altered signaling pathways in an oesophageal adenocarcinoma cell line following co-culture with isolated adipocytes from viscerally obese oesophageal adenocarcinoma patients (n=6).
