Abstract
OBJECTIVES: To investigate the effect of propofol on invasion and migration of human colon cancer cell line SW480 and the JAK2/STAT3 pathway. METHODS: Human colon cancer cell line SW480 was divided into a control group, 3 propofol treatment groups (with 2, 4 and 8 μg/mL propofol treatment, respectively), and a propofol+colivelin group. Lactate dehydrogenase (LDH) activity and cell proliferation was evaluated by detection kit and 3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl-2-H-tetrazolium bromide (MTT) method, respectively. Cell migration and invasion were detected by Transwell assay. Western blotting was performed to detect the protein expression levels of JAK2, p-JAK 2, STAT3 and p-STAT3 in colon cancer cell line SW480. RESULTS: Compared with the control group, the LDH activity was significantly increased in the propofol treatment groups (P<0.05). The cell proliferation, migration, invasion as well as p-JAK2 and p-STAT3 in colon cancer cell line SW480 in the propofol treatment groups were significantly decreased (allP<0.05). Compared with the propofol treatment groups, the p-STAT3 level, proliferation, migration and invasion in the colon cancer cell line SW480 were significantly increased in the propofol+colivelin group (allP<0.05). CONCLUSIONS: Propofol can inhibit the proliferation, migration and invasion of human colon cancer cells by inhibiting JAK2/STAT3 signaling pathway.
