Abstract:
Objective To study the influences of safflower yellow on the proliferation,apoptosis and cell cycle of non-Hodgkin's lymphoma(NHL)by regulating Wnt/β-catenin signaling pathway.Methods Raji cells were cultured in vitro and randomly divided into control group(conventional culture),safflower yellow group(30 μg·mL-1 safflower yellow),lithium chloride group(20 mmol·L-1 LiCl)and safflower yellow+LiCl group(30 μg·mL-1 safflower yellow+20 mmol·L-1 LicL).Cell proliferation,apoptosis,cell cycle distribution,apoptosis and cell cycle related protein expression were detected in each group.Nude mice were subcutaneously inoculated with Raji cells in the right anterior armpit to construct the NHL transplanted tumor model,and they were randomly grouped into Nu-control group,Nu-safflower yellow(7.5 mg·kg-1 safflower yellow)group,Nu-LiCl(1 mg·kg-1 safflower yellow)group,Nu-safflower yellow(7.5 mg·kg-1 safflower yellow)+LiCl(1 mg·kg-1 safflower yellow)group.After grouping and treating with safflower yellow and LiCl,the tumor weight and volume of nude mice in each group were measured.Results The Wnt1 protein levels of control group,safflower yellow group,LiCl group and safflower yellow+LiCl group were 0.64±0.11,0.19±0.04,1.07±0.40 and 0.59±0.07,respectively;the apoptosis rates were(5.13±0.67)％,(57.68±7.31)％,(0.91±0.29)％,(7.24±1.40)％,respectively;the protein levels of B-cell lymphoma-2(Bcl-2)were 0.53±0.09,0.09±0.02,0.99±0.14,0.49±0.07;the protein levels of P21 were 0.56±0.12,1.08±0.20,0.13±0.04,0.59±0.11,respectively.Compared with the control group,there were statistically significant differences of the above indexes between the safflower yellow group and LiCl group,the safflower yellow+LiCl group and the safflower yellow pigment group(all P＜0.05).The tumor volume of Nu-control group,Nu-safflower yellow group,Nu-LiCl group and Nu-safflower yellow+LiCl group was(915.34±61.43),(578.46±42.54),(1 310.84±93.16),(878.75±56.20)mm3,respectively;the tumor weight was(0.86±0.13),(0.45±0.09),(1.31±0.15),(0.75±0.17)g,respectively.Compared with the Nu-control group,there were statistically significant differences of the obove indexes between the Nu-safflower yellow group and Nu-LiCl group,the Nu-safflower yellow+LiCl group and the Nu-safflower yellow pigment group(all P＜0.05).Conclusion Safflower yellow can down regulate the expression of Wnt/β-catenin pathway protein,thereby inducing the cell cycle arrest of NHL cells,inhibiting their proliferation and tumor growth in nude mice,and promoting their apoptosis.
