Fig. 2. MHC I in Saphonecrus globosus Schweger and Tang 2015

Fig. 2. MHC I isoform distribution and single fiber cross-sectional area (CSA). (A) Representative immunofluorescent images of MHC I (green) fibers in gastrocnemius muscles in each group. Red represents laminin stain of myofiber interstitial tissue. Scale bar = 50 μm. (B) The changes in MHC I isoform distribution (%) in mice and Daurian ground squirrels. (C) The changes in muscle single fiber CSA in mice and Daurian ground squirrels. CON: control mice, OB: mice after 3 months of ingesting high fat diet, SA: summer active Daurian ground squirrels, PRE: pre-hibernation, squirrels that finished natural fattening, sacrificed in late-autumn (end of September, 30–40 d before hibernation). Values are mean ± SEM, n = 6. *p <0.05 compared with CON group.
