Fig. 11From: The SH3 and cysteine-rich domain 3 (Stac3) gene is important to growth, fiber composition, and calcium release from the sarcoplasmic reticulum in postnatal skeletal muscleCaffeine-induced contractions in EDL and SOL muscles from tamoxifen-injected Stac3 fl/fl and Stac3 fl/fl Tg Cre mice at 8 weeks of age. The EDL and SOL muscles from mice 4 weeks after tamoxifen injection were stimulated by 25 mM caffeine. a Representative contractile responses. Black arrows indicate addition of caffeine. b Summary stress (mN/mm2) responses. Values are not different (P > 0.05) between Stac3 fl/fl and Stac3 fl/fl Tg Cre (n = 4 mice for Stac3 fl/fl; n = 5 mice for Stac3 fl/fl Tg Cre)Back to article page
