Figure 6From: Catecholamine up-regulates MMP-7 expression by activating AP-1 and STAT3 in gastric cancerβ2-AR and MMP-7 were overexpressed in gastric cancer tissues. A, five gastric cancer tissue samples were collected. The expression of β2-AR and MMP-7 was analyzed by immunohistochemistry. B, the expression of MMP-7, β1-AR and β2-AR in the cancerous, peri-cancerous and metastatic tissues was analyzed by Western blot. C, the level of MMP-7 mRNA in the cancerous, peri-cancerous and metastatic tissues was analyzed by real-time PCR.Back to article page
