Figure 1. A, Expression of glycoprotein nonmetastatic melanoma protein B (GPNMB) in human cervical cancer patients as well as in normal cervix epithelium from GEO database. B, RT-PCR and western blot assay were performed to evaluate the mRNA and protein expressions of GPNMB in human cervical cancer cells SiHa, HeLa, and ME-180 cells, as well as in normal cervical epithelial cells. Data are reported as means±SE. *P<0.05, **P<0.01 vs Normal (ANOVA).
