The mRNA and protein expression levels of SERPINH1 and COL5A1 in GBM cell lines and astrocytes (SVGP12), assessed using RT-qPCR and western blotting (Figure 4A and 4B; one-way ANOVA, P < 0.05; statistical results shown on the right), were inconsistent. The gene discussed is COL5A1; the disease is glioblastoma.
