Abstract:
Objective:To investigate the effect and mechanism of Wogonin on CD3AK cell proliferation and cytotoxicity to SMMC-7721.Methods:CD3AK cells were cultured from peripheral blood mononuclear cells ( PBMC) in vitro by a variety of cytokines for 7 d,and treated with different concentrations of Wogonin for 48 h.CD3AK cells proliferation was measured by CCK-8 assay.SMMC-7721 cell growth was detected by MTT.The expression of perforin (PFP),granzyme B (GrB) and CD107a on CD3AK cells were measured by flow cytometry ( FCM).The cytotoxicity to SMMC-7721 cells was detected by LDH release assay.The expression of ERK1/2 on CD3AK cells was detected by Western blot.The mobility of SMMC-7721 cells was detected with transwell chambers.The merge of SMMC-7721 cells were measured with Wound healing assay.Results:Wogonin could significantly promote CD3AK cells proliferation, especially at 3.2 mg/L (23%higher than that of control group,P<0.05).The highest cytotoxicity to SMMC-7721 was also at the con-centration 3.2 mg/L (60.4%).The expression of PFP,GrB,CD107a were significantly higher than that of control group( P<0.05).The expression of ERK1/2 was obviously improved,especially at 12.5-0.8mg/L.After treated with Wogonin 50,12.5,3.2,0.8,0.2 mg/L for 48 h,the lowest transwell cell was at 12.5 mg/L and lowest merge rate was at 3.2 mg/L.Conclusion:Wogonin could promote CD3AK cell proliferation and enhance the cytotoxicity to SMMC-7721.Wogonin could also inhibit SMMC-7721 cell growth,migration and cell merge.The mechanism may be related to activated ERK1/2 and increase the expression of PFP,GrB,CD107a.
