Figure 7. The expression levels of GBP1. (A) The coefficients of the five model genes. (B, C) The GBP1 expression level in osteosarcoma and non-tumoral paired samples, based on the GSE99671 and GSE225588 cohort. (D) The qRT-PCR result of GBP1 in hFOB 1.19, MG63, HOS, Saos-2 cell lines. (E) The expressions of GBP1 in tumor and adjacent normal tissues. *P < 0.05, **P < 0.01 and ***P < 0.001.
