Our research group is interested in genetic dissection of human complex diseases using the state-of-the-art multi- and inter-disciplinary approaches of genomic technologies, and statistical and bioinformatical methods. The complex disease we are focusing on is osteoporosis, which is a prevalent, debilitating disorder characterized by bone fragility and an increased risk of low-trauma fractures. The approaches we are using involve genome-wide association analyses, genome-wide transcriptome analyses, proteome-wide protein expression profiling and in vivo and in vitro functional analyses of specific genes of interest. Currently, we are funded by several NIH grants for genetic, genomic and proteomic research of osteoporosis, including a P50 Specialized Center grant (1 P50 AR055081-01) for studying osteoporosis using the "genomic convergence analyses" approach.
Using the same genomic strategies, we are extending our research to other human complex diseases, including obesity, sarcopenia and periodontitis, and other human complex traits, including age at menarche/menopause and behavior traits, e.g., smoking, drinking and exercise. We are also extending our research of complex diseases from genome to epigenome, e.g., we are performing epigenome-wide profiling of osteoporosis at micro-RNA, DNA phosphorylation and histone modification levels. In particular, we are interested in developing novel statistical methods and bioinformatics tools for analyzing and managing large, complex datasets in genomic and epigenomic research.
Through Louisiana Osteoporosis Study (LOS), we are building a large research cohort and database for human complex disease studies. The LOS will enroll >20,000 subjects of different ethnicities in New Orleans, Baton Rouge and their surrounding areas. Each subject will be phenotyped for body composition (including bone mineral density, lean and fat mass), muscle function, and blood pressure etc., and assayed for important health-related and life-style information. Their blood samples will be collected for extraction of DNA, RNA and proteins and for cell isolation and biobanking. The LOS will become a sample pool for selecting subjects of extreme phenotypes (e.g., extremely high vs. low bone mass) for our ongoing funded and future genomic and epigenomic studies.
