This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. The subproject and investigator (PI) may have received primary funding from another NIH source, and thus could be represented in other CRISP entries. The institution listed is for the Center, which is not necessarily the institution for the investigator. A major objective of this project is to characterize the abnormalities of vascular gene expression occurring in early, subclinical stages of vascular disease, as assessed by large artery function, in adult obesity and to assess its correlates and the potential pathobiological mediating pathways between vascular dysfunction and vascular gene expression. While compelling evidence indicates that genetic and other biological factors predispose to obesity and hypertension, these common, co-occurring disorders likely reflect a complex interplay between biological factors and the psychosocial and cultural environment. Taken together, this series of studies will be among the first to link changes in human vascular mRNA expression profiles with physiologic alterations in vascular function and obesity. Overall, it is anticipated that these experiments will provide new insights into the molecular basis of vascular stiffness and endothelial dysfunction in high-risk African American obese subjects.
