The expression of STARS and RhoA protein in CS-exposed and control mice.

Notes: Western blot analysis showed that the protein levels of STARS and RhoA in the quadriceps muscle of CS-group mice were markedly lower than those in the control group. Densitometric analysis showed the amount of STARS and RhoA in the quadriceps muscle of CS-group mice to be 79% and 50% lower than that in control mice, respectively. The protein levels of STARS and RhoA were normalized to those of GAPDH protein. The values are shown as mean ± SEM (n=4 per group). *P<0.05, **P<0.001 compared with the control group.

Abbreviations: CS, cigarette smoke; Ctrl, control; GAPDH, glyceraldehyde 3-phosphate dehydrogenase; RhoA, ras homolog gene family, member A; STARS, striated muscle activator of Rho signaling; SEM, standard error of mean.
