- Abstract: Objective To observe the effect of Tongxie Yaofang-containing serum on the cell cycle and apoptosis of colon cancer HCT116 cells,and to explore its possible biological mechanism.Methods Colon cancer HCT116 cells were divided into blank group and Tongxie Yaofang-containing serum group with different concentrations.Cell proliferation and activity detection-8(CCK8)was used to detect the effect of each group on the viability of HCT116 cells at 24,48 and 72 h;Flow cytometry was used to detect the apoptosis and cycle arrest of HCT116 cells induced by different concentrations of Tongxie Yaofang-containing serum;Western blot was used to detect the protein expression level of Cell Cycle Regulatory Protein P21(P21),Cyclin B1,cyclin-dependent protein kinases-1(CDK1),B-lymphoma-2(Bcl-2),Bcl-2-related X protein(Bax),phosphatidylinositol-3-kinase(PI3K),phosphorylated phosphatidylinositol-3-kinase(p-PI3K),protein kinase B(Akt)and phosphorylated protein kinase B(p-Akt)after different concentrations of Tongxie Yaofang-containing serum intervention.Results CCK8 showed that compared with the 10%blank group,10%Tongxie Yaofang-containing serum had a significant inhibitory effect on the viability of HCT116 cells only at 48 h(P<0.01);Compared with the 20%blank group,20%Tongxie Yaofang-containing serum could inhibit the viability of HCT116 cells at 48 and 72 h(P<0.01,P<0.05),and the increase of blank serum will not inhibit the viability of HCT116 cell,so 10%blank serum and 48 h were selected as the drug control and intervention time in the subsequent experiment.Flow Cytometry showed that,compared with the blank group,10%and 20%Tongxie Yaofang-containing serum could arrest HCT116 cell cycle in G2/M phase after 48 h of intervention(P<0.01),and induce HCT116 cell apoptosis.At the same time,Western blot showed that Tongxie Yaofang-containing serum could increase the expression of P21 and Bax to varying degrees,and reduces Cyclin B1,CDK1,Bcl-2,p-PI3K,p-Akt expression(P<0.05,P<0.01).Conclusion Tongxie Yaofang can inhibit the proliferation and induce apoptosis of colon cancer HCT116 cells,and its mechanism may be related to the inhibition of PI3K/Akt signaling pathway.
