Effects of hindlimb irradiation on tibialis anterior myosin heavy chain IIA and IIB expression and size. A The percentage of type IIA and IIB myofibers. B Mean cross-sectional area (CSA) of type IIA and IIB myofibers. C Mean CSA distribution of type IIA myofibers. D Mean CSA distribution of type IIB myofibers. The frequencies of small and large myofibers (±2SD of mean) were compared by Chi-square analysis. Values are means ± standard error. Statistical significance was set at P<.05. Black box, Control. White box, 4x4 Gy. Grey box, 16 Gy. μm = micrometer; Gy = gray. * = statistically different from control; † = statistical difference between control and 4x4 Gy; ‡ = statistical difference between control and 16 Gy; # = statistical difference between 4x4 Gy and 16 Gy.
