From: Overexpression of RRM2 decreases thrombspondin-1 and increases VEGF production in human cancer cells in vitro and in vivo: implication of RRM2 in angiogenesis

Figure 1

Overexpression of RRM2 decreased TSP-1 expression in KB-M2-D and KB-HURs cells. (A) Western blot analysis confirmed that only RRM2 was overexpressed in KB-M2-D and KB-HURs; the expression of RRM1 and p53R2 was not significantly modulated in both KB-M2-D and KB-HURs; and the expression of TSP-1 was significantly decreased in KB-M2-D and KB-HURs cells by 60%~70% (TSP1-CM: TSP-1 in concentrated condition medium, TSP1-T: TSP-1 in total protein). (B) Representative quantitative densitometric analysis of RRM2 and TSP-1 expression. Signal intensities were normalized to that of β-actin serving as loading control; data was presented as fold of KB. (C) q-RT-PCR analysis confirmed that RRM2 mRNA was dramatically overexpressed in KB-M2D and KB-HURs compared with parental KB (**p < 0.01). Values of q-RT-PCR were the mean ± SD of three independent experiments and presented as ratio to the level of parental KB cells. (D) q-RT-PCR analysis showed TSP-1 mRNA was significantly decreased in KB-M2D and KB-HURs compared with parental KB (**p < 0.01).
