Description: |
Objective: The aim of this study was to determine the effect of age of obesity onset on senescence-related markers in abdominal (AB) and femoral (FEM) subcutaneous adipose tissue (SAT) before and after moderate (~10%) weight loss. Methods: AB and FEM SAT were collected from human females with childhood-onset obesity (CO) or adult-onset obesity (AO) before and after diet- and exercise-induced weight loss. Immunofluorescence analysis of ?H2AX/RAD51 (DNA damage/repair markers) and p53/p21 (senescence markers) was conducted in cultured preadipocytes, and senescence-associated ß-galactosidase (SA-ß-gal) activity was measured in SAT. Results: CO had proportionately more AB and FEM preadipocytes with DNA damage (?H2AX+ ) and senescence markers (p53+ and/or p21+ ) than AO at baseline. The proportion of ?H2AX+ FEM preadipocytes declined with weight loss in CO and was similar between groups after weight loss. The number of ?H2AX foci in ?H2AX+ preadipocytes decreased similarly between groups and regions with weight loss in parallel with an increase in RAD51. The proportion of p53+ and p21+ preadipocytes and SA-ß-gal+ cells in SAT did not change with weight loss, but the total p21 intensity in p53+ /p21+ FEM preadipocytes declined in AO. Conclusions: These results provide preliminary evidence that females with CO have an accelerated preadipocyte aging state that improves with weight loss in terms of DNA damage but not senescence. |
