VEGFA and glioblastoma: Western blot analysis showed a significant increase in VEGF expression in glioblastoma control cells (Figure 5E (A172) and Figure 5F (U138), see densitometry analysis, respectively), while the association between 5Z-7-Ox and TMZ significantly down-regulated its expression (Figure 5E of A172 cell line, Figure 5F (3;9;12) = 32.31, p < 0.001; Figure 5F of U138 cell line, Figure 5F (3;4;7) = 91.39, p < 0.001; see densitometry analysis, respectively) much more than single components.
