Fig. 1: Aging and obesity result in a significant decline in muscle mass.
From: Transcriptome profiling of fast/glycolytic and slow/oxidative muscle fibers in aging and obesity
A Hematoxylin and eosin (H&E) staining of tibialis anterior (TA) sections. B Statistical results of the number of muscle fibers. C Statistical results of the average cross-sectional area (CSA) of TA fibers. D Distribution of muscle fiber CSA, data are expressed as percentages. E Average CSA of type I fibers. F Average CSA of type IIA fibers. G Average CSA of type IIB fibers. n = 3–6; *P < 0.05, **P < 0.01, ***P < 0.001, ****P < 0.0001; # indicated control group vs. Ob/Ob group, P < 0.05; & indicated control group vs. aged group, P < 0.05.
