From: Niacin supplementation induces type II to type I muscle fiber transition in skeletal muscle of sheep
Muscle fiber type distribution (A), and relative mRNA levels of fiber-specific MHC isoforms (B) of LD muscle, SM muscle, and ST muscle of sheep administered either no (control group) or 1 g niacin per day (niacin group) for 4 wk. Bars represent means ± SD, n = 8 sheep/group. Representative images from fiber typing for each group are shown below the graph showing fiber type distribution, with the “black” areas being the type I fibers and the “grey” ones being the type II fibers. *different from control group, P < 0.05, #different from control group, P < 0.15.
