Little is known about the turnover of adipose cells in the fat depots of normal animals and human subjects. However, microarray analysis of adipose cell gene expression in high risk insulin-resistant human subjects suggests that a reduced rate of adipose cell turnover is associated with enhanced adipose cell size and systemic insulin resistance. New technology now permits a detailed analysis of adipose cell size including the detection of smaller cells which may be in the process of active differentiation. We propose to examine the relationship between adipose cell size distribution and systemic insulin resistance in obese human subjects. Adipose tissue biopsies will be obtained at Stanford University under protocols and consent forms approved by the Stanford University IRB. Only procedures already being performed on subjects under these protocols will be used.

Without regard to gender, race, or socioeconomic status, all subjects will be adult men and women. The racial/ethnic composition of the study population will be reflective of the communities surrounding Stanford University. Subjects will be recruited through placement of advertisements in local newspapers, but no subjects will be seen at NIH.
