Figure 1. Changes in the body weight, and absolute and relative muscle weight of heat shock transcription factor 1 (HSF1)-null and wild-type mice following 2 and 4 weeks of functional overloading.

Relative muscle weight: the muscle weight relative to body weight (BW); +/+, wild-type mice; −/−, HSF1-null mice; Control, control muscle; Overloaded, overloaded muscle; 2 weeks, 2 weeks of overloading; 4 weeks, 4 weeks of overloading. Values are means ± SEM. n = 6/group at each time point. *: significant difference at p<0.05.
