Project description:Multiple endocrine neoplasia type I (MEN1) is a familial cancer syndrome characterized primarily by tumors of multiple endocrine glands. The gene for MEN1 encodes a ubiquitously expressed tumor suppressor protein called menin. Menin was recently shown to interact with several components of a trithorax family histone methyltransferase complex including ASH2, Rbbp5, WDR5, and the leukemia proto-oncoprotein MLL. To elucidate menin's role as a tumor suppressor and gain insights into the endocrine-specific tumor phenotype in MEN1, we mapped the genomic binding sites of menin, MLL1, and Rbbp5, to approximately 20,000 promoters in HeLa S3, HepG2, and pancreatic islet cells using the strategy of chromatin-immunoprecipitation coupled with microarray analysis. We found that menin, MLL1, and Rbbp5 localize to the promoters of thousands of human genes but do not always bind together. These data suggest that menin functions as a general regulator of transcription. Keywords: ChIP/chip NHGRI Menin ChIP-Chip

Proteomics at large: Discovery and replication of plasma proteomic biomarkers in independent cohorts - Overweight and obese patients of the Weight Management Clinical program of The Ottawa Hospital

Project description:Holistic human proteome maps are expected to complement comprehensive profile assessment of health and disease phenotypes. However, methodologies to analyze proteomes in human tissue or body fluid samples at relevant scale and performance are still limited in clinical research. Their deployment and demonstration in large enough human populations are even sparser. In the present study, we have characterized and compared the plasma proteomes of two large independent cohorts of obese and overweight individuals using shotgun MS-based proteomics. One cohort comes from a Canadian single-center clinical weight management program while the other one belongs to a multicenter pan-European weight loss study (i.e., the DiOGenes study for which MS proteomic data have been already deposited to the ProteomeXchange Consortium with the dataset identifier PXD005216). The MS proteomic data deposited herein corresponds to the cohort coming from the Weight Management Clinical program of The Ottawa Hospital.
