From: Reduced expression of SMAD4 in gliomas correlates with progression and survival of patients
Expression of SMAD4 protein in glioma and normal brain tissues by Western blot analysis. (A) SMAD4 expression levels in glioma and normal brain tissues. (B) SMAD4 expression levels in glioma with different WHO grades. (C) SMAD4 expression levels in normal brain tissues and glioma with different WHO grades. 'N' refers to normal brain tissues; 'Ca' refers to glioma tissues; 'Ca_ I'~' Ca_ IV' refer to glioma tissues with WHO grade I~ IV. β-actin was used as a control for equal protein loading. Values are means ± SD. '*', p < 0.05, comparison with normal brain tissues; '**', p < 0.001, comparison with normal brain tissues.
