Ongoing cardiac functional screening in various nonmuscle myosin mutants for identification of cardiac phenotypes, influence of age on phenotype and guidance of breeding (fellows Ma, Jana). 3. Bodine D., NHGRI: Progeria study, Collaboration with NHLBI: Drs. Nabel E., Cannon R.;NIH: Collins F.: Progeria study #2. Double copy mutant progeria model pilot and treatment studies with aorta imaging, diameter measurements and cardiac function. Primary scientist, Erdos M. 4. Boehm M., NHLBI. MI studies, scar identification and function, effect of treatment with TGF beta neutralizing antibody (fellows Elagha A., Yang D.). In addition a functional study was done to make a comparison to echo performed by the Phenotyping Core to compare techniques in evaluating function with a focal wall defect. 5. Horowits R., NIAMS. (fellow Crawford G.). Transgenic mice (N-RAP) to characterize for cardiac phenotype. Histology is suggestive of RV abnormality. Finding increasing severity of cardiac functonal abnormality, both LV and RV, via MRI with age, copy number. 6. Rochman M., Bustin, NCI: collaboration with Dr. Adestein. NSBP1 protein KO determine if there is a cardiac phenotype with or without stress. 7.

Hwang P., NHLBI: p53: see Park JY et al. Circ. Res. 2009 2. Neufeld E., NHLBI: Imaging pig renal artery collagen for comparison to microscopy showing collagen formation at the artery junction. Testing determined that the collagen at the site did not incorporate a small molecule Gd chelate preferentially compared to the remainder of the vessel. 3. Sack M., NHLBI, dobutamine stress testing on mice with modified levels or lacking mitochondrial proteins park2 and/or pink1. (fellow Stevens) 4. Segars J., NICHD, fellow Guo C. (collaboration with Robert Adelstein): dobutamine stress on KO vs WT. Group is performing additional histopath and ECG analyses prior to concluding this study. 5.

Invest. 2009 In addition, there are active ACUC protocols that are not being used currently that are eligible to perform studies at any time during the life of the protocol.
