Figure 3From: Expression and aberrant promoter methylation of Wnt inhibitory factor-1 in human astrocytomasCorrelation between hypermethylation and decreased or weak expression of WIF-1 in astrocytomas. A significant downregulation of the protein(A) and mRNA(B) expression of WIF-1 was observed in astrocytomas with promoter methylation(both P < 0.001). The bars in the graph showed the mean ± SD.Back to article page
