Also, the protein level of PROS1 in glioma samples was higher compared to that in normal samples in the HPA and CPTAC database (Figures 1H, I), and our western blotting and qRT-PCR assays results further demonstrated that PROS1 protein and mRNA expression were increased in U-87MG and LN-229 glioma cell lines than in SVGp12 normal cell line (Figures 1J, K). Here, PROS1 is linked to glioma.
