Mission Statement To develop new resources, reagents, and education programs for investigators engaged in NHLBI-related research.
PGA Mission • Provide new resources and reagents to link genes to biological function and make these readily available to the NHLBI community. • Facilitate workshops, courses, and visiting scientist programs to train investigators in the technologies being applied in the PGAs. • Rapidly disseminate data through the world wide web and public databases.

BayGenomics http://baygenomics.ucsf.edu Focus: Cardiopulmonary Development and Disease • Apply custom gene-trap vectors to inactivate genes in ES cells and to evaluate the functional importance of these in cardiopulmonary development and disease using computational approaches, expression profiling, in situ hybridization studies, and in select cases in animals. PI: Dr. Stephen G. Young
CardioGenomics http://www.cardiogenomics.org Focus: Cardiovascular Development, Adaptation, and Remodeling • To link genes to function, dysfunction, and structural abnormalities of the cardiovascular system caused by clinically relevant genetic and environmental stimuli. PI: Dr. Seigo Izumo
HopGenes http://www.hopkins-genomics.org Focus: Tissue Remodeling in Cardiopulmonary Disease • To identify the genes involved in tissue remodeling using expression profiling to explore the pathology of asthma, chronic obstructive pulmonary disease, cystic fibrosis, lung transplantation, acute lung injury, scleroderma, sarcoidosis, pulmonary hypertension, ischemic cardiomyopathy, and cardiac transplantation. PI: Dr. Joe G.N. Garcia
Innate Immunity http://innateimmunity.net Focus: Genetics of HLB Disorders • Explore genetic susceptibility in asthma, chronic obstructive pulmonary disease, myocardial infarction and deep venous thrombosis by evaluating polymorphisms in genes involved in innate immune responses. PI: Dr. Fernando D. Martinez
JAX PGA http://pga.jax.org Focus: Mouse Models of HLBS Disorders • Apply a phenotype-driven approach to identify the genetic mechanisms underlying the physiology and pathophysiology of atherosclerosis, hypertension, lung function, blood formation, thrombosis, obesity, inflammation, and sleep function. PI: Dr. Luanne L. Peters
PARABIOSYS http://genetics.mgh.harvard.edu/Parabiosys/ Focus: Genetics of Inflammation and Stress • To identify and characterize the gene networks activated by pro-inflammatory, metabolic, and pathogenic stresses affecting cardiovascular and pulmonary systems. PI: Dr. Brian Seed
Berkeley PGA http://pga.lbl.gov Focus: Cardiovascular Gene Expression • Apply comparative genomics to identify and understand the role of cis-acting regulatory elements that affect the expression of cardiovascular genes. PI: Dr. Edward M. Rubin
PhysGen http://pga.mcw.edu Focus: Rat Models of HLBS Disorders • Dissect multigenic common HLBS diseases through the development of panels of chromosomal substitution strains of rats (consomic rat panels). PI: Dr. Howard J. Jacobs
Seattle SNPs http://pga.mbt.washington.edu Focus: Inflammation and Genetic Variability • To identify variable sites in human genes to expand the resources available to explore the role of inter-individual variation and its relationship to disease risk, outcome and treatments for common human disorders. PI: Dr. Deborah A. Nickerson
Southwestern http://pga.swmed.edu Focus: Cell Injury and Inflammation • Elucidate the basic mechanisms underlying cell injury and inflammation through a combination of genomic and proteomic approaches. PI: Dr. Stephen A. Johnston
TREX http://pga.tigr.org Focus: Gene Expression in HLBS Disorders • Explore gene-environment interactions using rodent models of human disease and cDNA microarray assays to elucidate patterns of gene expression in heart, lung, blood, and sleep disorders. PI: Dr. John Quackenbush

Baylor College of Medicine RAT GENOME SEQUENCING PROJECT NHGRI/NHLBI Howard Jacob MCW Marco Marra UBC Shaying Zhao TIGR Peter Tonellato Rat GDB CHO Pieter de Jong Univ Utah Robert Weiss
Goals Produce a `draft sequence` of the genome, Assembly and first-pass annotation, Cross-species comparison, A public assembler, Foundation for a finishing effort, Interface with community,
Fold-Coverage Timelines (Year One) (Cumulative) All in MOU (with data release policy)
Strategy: Strain Selection: Howard Jacob’s BN/SsNHsd This Brown Norway strain has only seven heterozygous markers in the more than 4,000 tested i.e. it is very `isogenic` as a representative strain.
New BAC Library Made by Pieter de Jong from BN/SsNHsd female, One enzyme so far ~200 kb inserts 10 X coverage Second enzyme to come? Doug Smith pursuing chr Y library,
Fingerprints: UBC, ~40,000 for `de-randomization` ~200,000 for f`print assembly, BES: TIGR, ~200,000 paired ends
Strategy: BAC Skims BAC skims to cover 90% of genome Originally 20,000 150 kb `de-randomized` BACs @ 1.0 x coverage, (384 reads per BAC) = 1 x clone coverage = 67% - 80% coverage ~ 5,000 gaps for walks, Now 15,000 200 kb BACs @768 reads per BAC and 1.7 X coverage
Strategy: BAC Skims (cont`d) Reads in BACs: 2kb paired end (dye term) +++ 10kb paired end (dye term) -- M13 (with primer chemistry) ?
Strategy: WGS Reads 2kb paired end (dye term) +++ 10kb paired end (dye term) +++ 5kb and 50kb discussed, M13 (with primer chemistry) ?
Challenges: - Usual - Assembly - Data `purity`
Atlas: A whole genome assembler
