Figure 2From: Herbal compound "Songyou Yin" reinforced the ability of interferon-alfa to inhibit the enhanced metastatic potential induced by palliative resection of hepatocellular carcinoma in nude mice Molecular alterations. (A10 Gelatin zymography assay showed palliative resection activated MMP2. M, size marker; P, positive control. (A2) The percentage of MMP2 activity was elevated 1.4-fold as compared with control (P < 0.01). (A3) Palliative resection up-regulated the tumor MMP2 level (P < 0.01). (B) Palliative resection down-regulated tumor the TIMP2 level (P < 0.05). (C) Palliative resection up-regulated tumor the VEGF level (P < 0.05). The bars indicate the means ± SD.Back to article page
