Abstract:
Objective To study the effect of matrine on the expression of a proliferation-inducing ligand (APRIL) in colorectal cancer cell line (SW480 cell). Methods MTT assay was used to evaluate the inhibitory effect of matrine on SW480 cells. The protein and mRNA levels of APRIL in SW480 cells were determined by immunohistochemistry and real-time fluorescence quantitative PCR (RFQ-PCR). SW480 cells were treated with 0.5,1.0,2.0 mg/ml of matrine for 24 h, 48 h and 72 h. FU and blank were served as drug control and blank control groups, respectively. Results Matrine had obviously inhibitory effect on proliferation of SW480 cells in a time- and dose-dependant manner. The expression of APRIL was strong in SW480 cells. When treated with 50,100,200 ug/ml of FU, the APRIL mRNA levels in SW480 cells raised gradually and reached the highest levels at 72 h after treatment, which were significantly higher than those in blank control group (all P value<0.001). When treated with 0. 5,1.0, 2.0 mg/ml of matrine, the APRIL mRNA levels in SW480 cells increased at 24 h after treatment, which were significantly higher than those in blank control group (all P value<0. 001), and then decreased gradually and almost equal to level of blank control group at 72 h. Conclusion In treatment with FU, the survival cells.may have stronger ability of proliferation due to higher expression of APRIL in SW480 cells. Anti-APRIL therapy might be an important assistant treatment to counter the impact of APRIL. Matrine will not cause persistent increase of APRIL mRNA levels in SW480 cells, so it might be a helpful drug in anti-tumor theraphy.
