Abstract:
Objective To investigate the regulatory effects of resveratrol on proliferation, adhesion, migration, invasion,epithelial-mesenchymal transition(EMT), and Janus kinase 2(JAK2)/signal transducer and activator of transcription 3(STAT3) signaling pathway of human glioma cells T98G, so as to provide theoretical basis for the related research of resveratrol in the treatment of glioma.Methods Human glioma T98G cells were cultured in vitro and divided into control group(without intervention), experimental groups(12.5, 25, and 50 μmol/L resveratrol groups), positive drug group(50 mg/L 5-fluorouracil), inhibitor group(50 μmol/L resveratrol + 50 μmol/L JAK2/STAT3 signaling inhibitor AG490) and activator group(50 μmol/L resveratrol + 0. 5 μmol/L JAK2/STAT3 signaling activator colivelin), which were intervened for 24 h. The cell viability, proliferation rate, adhesion ability, migration ability, invasion ability, EMT and JAK2/STAT3 signaling pathway related protein expression levels were analyzed by cell count(CCK-8), 5-ethynyl-2′deoxyuridine(EdU), adhesion test,scratch test, Transwell and Western blot.Results Compared with the control group, the cell viability of 12. 5 and 25 μmol/L resveratrol groups had no significant change(t = 1. 501 and 2. 167, respectively, P > 0. 05), while that of 50 μmol/L resveratrol group and the positive drug group decreased significantly(t = 7. 918 and 8. 020, respectively, P < 0. 05). The cell viability of 12. 5 and 25 μmol/L resveratrol groups increased significantly compared with the positive drug group(t = 6. 519and 5. 853, respectively, P < 0. 05), and that of 50 μmol/L resveratrol group was close to 50% and had no significant difference from that of the positive drug group(t = 0. 102, P = 0. 921, P > 0. 05). Compared with the control group, the proliferation rate, adhesion, migration, invasion ability and the protein expression of N-cadherin, vimentin, fibronectin(FN), p-JAK2,and p-STAT3 in 50 μmol/L resveratrol group and positive drug group significantly decreased(t = 4. 090-28. 510, respectively, P < 0. 05), while the expression of E-cadherin significantly increased(t = 16. 782 and 17. 291, respectively, P <0. 05). Compared with 50 μmol/L resveratrol group, the proliferation rate, adhesion, migration, and invasion ability, and the protein expression levels of N-cadherin, vimentin, FN, p-JAK2 and p-STAT3 of T98G cells in the inhibitor group significantly decreased(t = 3. 801-17. 980, respectively, P < 0. 05), while the expression level of E-cadherin protein significantly increased(t = 15. 256, P < 0. 05); the proliferation rate, adhesion, migration, and invasion ability, and the protein expression of N-cadherin, vimentin, FN, p-JAK2 and p-STAT3 of T98G cells in the activator group significantly increased(t =4. 235-27. 951, respectively, P < 0. 05), while the expression of E-cadherin significantly decreased(t = 14. 748, P < 0. 05).Conclusion Resveratrol can significantly inhibit the proliferation, adhesion, migration and invasion of human glioma T98G cells, which may be related to the inhibition of EMT process by inhibiting JAK2/STAT3 pathway signal transduction.
