TUNEL analyses of quadriceps in sedentary and exercised VCP^R155H/+ mice.

<p>TUNEL staining of quadriceps muscles from sedentary (A) WT and (B) VCP^R155H/+; exercised (C) WT and (D) VCP^R155H/+ mice at 19-months of age. Quadriceps muscles from (E) WT and (F) downhill exercised VCP^R155H/+ mice were stained with TUNEL (Magnification: 630X). (G) Quantification of TUNEL in the sedentary and exercised mice. Statistical significance is denoted by *<i>p</i><0.05, **<i>p</i><0.005, and ***<i>p</i><0.001 by Student one-tailed t test. The number of animals used was n = 8–10/group.
