Effect of Schisandrin B on Proliferation and Migration of Human SW620 Colon Cancer Cell Via VEGF/PI3K/Akt Signaling Pathway / 中国药学杂志

ABSTRACT

OBJECTIVE: To study the changes of VEGF signaling pathway in colon cancer patients and the effect of schisandrin B on SW620 cells and to analyze its possible mechanism. METHODS: The protein expression of VEGFA, VEGF-R2, PI3K, Akt and p-Akt in human cancerous colon samples and adjacent normal samples were detected by Western blotting. The proliferation of SW620 cells was detected by CCK-8 method. The mRNA expression of VEGFA, VEGF-R2, PI3K and Akt in SW620 cells were detected by real-time PCR. The protein expression of VEGFA, VEGF-R2, PI3K, Akt and p-Akt in SW620 cells were detected by Western blotting. RESULTS: The protein expression of VEGF-R2, PI3K, Akt and p-Akt in human cancerous colon samples was significantly higher than that in the adjacent normal samples(P<0.05). Compared with the control group, schisandrin B could significantly inhibit the proliferation and migration of SW620 cells, the mRNA expression of VEGFA, VEGF-R2, PI3K and Akt(P<0.01) and the protein expression of VEGFA, VEGF-R2, PI3K, Akt and p-Akt(P<0.05) in SW620 cells also were significantly decreased by schisandrin B. CONCLUSION: The VEGF/PI3K/Akt signaling pathway is activated in colon cancer patients. Schisandrin B could inhibit the activity and migration of SW620 cells and inhibit the VEGF/PI3K/Akt signaling pathway.
