It is currently estimated that half of all Americans over the age of 50 either already have osteoporosis or are at serious risk for the development of this disease. Low bone mass is associated with increased osteoporotic fracture risk and up to 85% of the variance in peak bone mass is heritable. Genome wide association studies (GWAS) in humans have identified a number of loci for bone mineral density (BMD);however, only a small fraction of the variance in BMD can be collectively explained by the identified loci. It has been postulated that BMD is controlled by many small effect size loci, and that much of this missing variance would be captured if these loci could be conclusively mapped. However, bone is not insulated from nor is it without consequence on the rest of an organism's physiology. It is well established that cardiovascular disease (CVD) and osteoporosis share common etiologies. Diagnosis of CVD is associated with increased risk of hip fracture, and low bone mass in women is an independent predictor of CVD. Furthermore, patient behaviors that increase risk for CVD (i.e. lack of exercise, smoking) are also risk factors for development of low bone mass. My research program has two main focuses: 1) determining the genes required for proper osteoblast development and function and 2) elucidating the impact of dietary cholesterol on these genes to impact upon osteoblast development and function.

Osteoblasts are mononuclear cells that differentiate from mesenchymal stem cells (MSCs). They function to form the protein matrix of the osteoid and to mineralize this matrix to produce healthy bone tissue. Mineralization rate and level by the osteoblast varies significantly among the inbred mouse strains, emphasizing that activity by these cells is genetically regulated. Using a variety of strategies including high-throughput RNAseq, genetic mapping and in-depth phenotyping of transgenic mouse models, I am investigating the genetic underpinnings that control osteoblast function. Low levels of HDL cholesterol and BMD are risk factors for CVD and osteoporosis respectively. It is well understood that dietary fat intake affects serum HDL cholesterol levels in certain genetic contexts, and I have shown that dietary fat can interact with certain genes to influence bone mass. Further, I have determined that genetic loci for these two phenotypes co-map with high frequency and these co-mapping loci may interact with dietary fat intake. I am using mouse models as discovery tools to better define the genetic relationship between serum HDL and BMD, and to determine how dietary fat impacts osteoblast maturation and function in the context of differing genetic backgrounds.
