The mRNA and protein expression of prognostic genes in OS samples. A The mRNA expression of prognostic genes relative to that of β-actin in OS and normal tissues. B–C The protein expression of prognostic genes relative to that of β-actin in OS and normal tissues. *: p < 0.05; **: p < 0.01; ****: p < 0.0001, ns: not significant.
