ABSTRACT
Objective To explore the status of C57BL/6J mouse brown fat adipogenic differentiation function with aging.Methods C57BL/6J female and male mice at the ages of 0-week (newborn),4-week,8-week,12-week old were selected from the same brood,brown adipose tissue was obstained from their interscapular region,and the brown adipose was identified by using immunohistochemical markers.Then the total RNA was extracted from the brown adipose and quality identification was determined at the same time.The expression levels of the related genes (PPARα,C/EBPα,PGC-1α,PPARγ,FOXC2,BMP7) induced by brown adipose adipogenic differentiation were detected by quantitative real-time PCR in 0-week,4-week,8-week,12-week mice.Results Uncoupling protein -1 (UCP1) immunohistochemical data indicated that positive deep-colour substance was brown adipose tissue.Quantitative Real-time PCR also indicated that the expression volume of adipogenesis gene gradually reduced with aging,and there were significant differences at the different time points [PPARα (F =11.96,P < 0.000 1),C/EBPα (F =9.39,P <0.000 1),PGC-1α(F =17.21,P <0.000 1),PPARγ(F =13.11,P <0.000 1),FOXC2(F =12.23,P <0.000 1),BMP7(F =16.44,P <0.000 1)].Conclusions The adipogenic differentiation ability and activity of mouse brown adipose gradually reduce with aging.But the regulatory factors for its function needs to be further investigated.
