Fig. 5From: Vitamin A regulates mitochondrial biogenesis and function through p38 MAPK-PGC-1α signaling pathway and alters the muscle fiber composition of sheepRetinoic acid affected mitochondrial function through PGC-1α signaling. A Representative images showing MitoTracker staining. B The relative intensity of MitoTracker staining. C SDH activity. D MDH activity. E Relative mRNA content of UQCRC1 and ATP5A1. F Protein expression of UQCRC1 and ATP5A1. Data were shown as mean ± SEM; n = 3 in each group, 3 replications were used during the experiment and each well was considered as an experiment unit from different lambs. a–cValues with different letters indicated significant differences (P < 0.05)Back to article page
