RecruitingClinical trialSingle Nuclei RNA-seq to Map Adipose Cellular Populations and Senescent Cells in Older SubjectsAll participants will undergo baseline biopsies of subcutaneous abdominal adipose tissue for cellular/molecular profiling via snRNA-seq and metabolic/physiological assessments (insulin sensitivity, glucose tolerance, and β-cell function). Older obese participants will be randomized into three arms: lifestyle intervention (n=24), senolytics (n=24), or placebo (n=24).
