Project description:WTCCC2 project genome-wide case-control association study for Ulcerative Colitis (UC) using the 1958 British Birth Cohort and the UK National Blood Service collections as controls.
Project description:A WTCCC2 project genome-wide association study for reading and mathematics ability in 3665 12-year-old individuals from the UK, genotyped on the Affymetrix 6.0 array. Details of the WTCCC2 analysis can be found in Davis et al. [Nat. Commun. 2014 July;5:4204]
Project description:mucosal biopsies were taken from patients at pre and post-argon plasma coagulation (APC) ablation of Barrett's oesophagus, and from healthy controls. Total RNA was extracted using Trizol. miRNA was reversed transcribed using a TaqMan® microRNA Reverse Transcription Kit (Life technologies, #4366596). miRNA profiling was performed with a high throughput TaqMan® OpenArray® Human microRNA panel (Life technologies, #4461104). The panel consisted of probes for 754 human miRNAs that are based on miRNA sequences derived from Sanger miRBase v14. Endoscopic surveillance remains the mainstay of cancer prevention in individuals with Barrett’s oesophagus, and definitive management by surgery or endoscopy is reserved for high grade dysplasia or cancer. There are several endoscopic treatments that are widely used for Barrett’s oesophagus, including argon plasma coagulation (APC). The normality of the regenerated neosquamous epithelium after ablation has been called into question. In the current study we profiled global microRNA expression in oesophageal mucosa before and after ablation of Barrett’s oesophagus using Argon plasma coagulation. Our aim was to investigate differences in microRNA expression between neosquamous and normal squamous tissues.
Project description:A WTCCC2 project genome-wide association study for pre-eclampsia (PA) in 4375 individuals from Colombia, genotyped on the Affymetrix 6.0 array.
Project description:A WTCCC2 project genome-wide association study for bacteraemia susceptibility in 4924 individuals from Kenya, genotyped on the Affymetrix 6.0 array.
Project description:We prepared miRNA from myofibroblats derived from normal oesophagus and esophageal cancers. miRCURYTM LNA Array ver5 was performed and comparisons were made by the dual (reference) method.
Project description:A WTCCC2 project genome-wide association study for psychosis endophenotype (PE) in 5831 individuals from UK, Germany, Holland, Spain and Australia, genotyped on the Affymetrix 6.0 array. Information about the family structure of the samples can be found in the .info file which accompanies the data. It should be noted that a number of samples in this study have no phenotype information including sex, case status and family membership. Details of the WTCCC2 analysis can be found in Bramon et al. [Biol Psychiatry. 2014 Mar 1;75(5):386-97].
