Tianjin Medical Journal 2014;(7):638-640
Objective To investigate the effect of cisplatin on proliferation and invasion of colorectal cancer cell line SW480. Methods SW480 cells were used as the research object, and untreated SW480 cells were used as the control group. Different concentrations of cisplatin was given at different times to intervene. The MTT, Transwell chamber and phos-phate determination methods were used to detect proliferation, invasion and Na+-K+-ATPase activity expression level in SW480 cells. Results The physiological concentration of cisplatin (70 μmol/L) inhibited the proliferation of SW480 cells at 48 h. There was no significant difference in the inhibition rate at 48 h compared with 72 h and 96 h. Treatment with 70 μmol/L cisplatin for 48 h reduced the number of cells through Matrigel membrane matrix. The Na+-K+-ATPase activity was significantly increased in 35, 70 and 140 μmol/L cells after treatment with 17.5, 35, 70 and 140 μmol/L of cisplatin in SW480 cells for 48 h, and Na+-K+-ATPase reached the highest level at 70 μmol/L of cisplatin. Conclusion The decreased activity of Na+-K+-ATPase may lead to the attenuation in proliferation and invasion of colorectal cancer cells, which may be associated with cisplatin resistance in colorectal cancer cell SW480.

Chinese Journal of Tissue Engineering Research 2005;9(27):223-225
BACKGROUND: Studies have shown that 160 mg/L tramethylpyrazine (TMP) can inhibit the proliferation of endothelial cells cultured in vitro,but whether TMP also inhibits vascular endothelial growth factor (VEGF)induced proliferation of vascular endothelial cells remains unkown. OBJECTIVE: To study the effect of rat serum containing TMP on vascular endothelial cell proliferation and its proliferation induced by VEGF. DESIGN: Randomized controlled experiment. SETTING: College of Traditional Chinese Medicine, Chongqing University of Medical Sciences. MATERIALS: The experiment was carried out in the Institute of Pediatrics, Chongqing University of Medical Sciences from March, 2002 to March, 2003 using human umbilical vein endothelial cell (HUVEC) line ECV304 and 30 female Wistar rats. METHODS: Thirty rats were randomly divided into 3 equal groups to receive intraperitoneal TMP injection at 143.0 mg/kg and 71.5 mg/kg and 0.8 mL normal saline (blank control group). All the injections were performed once a day for consecutive 7 days, then blood was collected from the intraperitoneal artery and diluted to 20%, 10%, and 5% in triplicate.Effect of TMP-containing serum on the proliferation of ECV304 cells was observed by means of in vitro culture and 3H-TdR incorporation as well as methyl thiazolyl tetrazolium (MTT) methods. MAIN OUTCOME MEASURES: ① Effect of TMP-containing serum on proliferation of ECV304 cells in in vitro culture and VEGF-induced proliferation of the cells.RESULTS:All the 30 rats survived the experiment without losses. The absorbance (A) and scintillation counting (minute-1) of the cells were significantly lower in 143.0 mg/kg TMP group than those in the control group treated with rat serum at the dilution of 5% (0.720±0.024 vs 0.816±0.068,3340.45±567.7 vs 5120.84±301.49), 10% (0.630±0.017 vs 0.798±0.015,2430.06±265.98 vs 5225.83±100.10), and 20% (0.765±0.027 vs 0.823±0.031,3570.45±130.52 vs 5256.82±183.18), and those in 71.5 mg/kg TMP group were also significantly lower than those in the control group after treatment with the serum of 10% (0.775±0.023, 4571.14±275.39) and 20%(0.749±0.012, 3287.25±144.82). In the experiment evaluating the effect of TMP serum on VEGF-induced proliferation of ECV304 cells, the A value and scintillation counting in the 143.0 mg/kg TMP group were significantly lower than those in the control group after the cells were treated with the serum of 5% (0.726 ±0.004 vs 0.964 ±0.004, 5760.46 ±49.64 vs 9821.82±128.05), 10% (0.712±0.004 vs 0.933±0.014, 5024.48±100.57 vs 9052.76±65.19), and 20% (0.717±0.003 vs 0.924±0.004, 5405.45±140.90vs 9197.07±169.92], and those of the cells treated with 71.5 mg/kg TMP serum of 10% and 20% were also significantly lower than those in the control group (0.703±0.005 and 7526.47±169.21 for 10% serum, and 0.693±0.006 and 5720.09±279.03 for 20% serum). CONCLUSION: The sera at the concentrations of 5%,10%, and 20%from rats treated with 143 mg/kg TMP and at higher concentrations from 71.5 mg/kg TMP-treated rats can inhibit the proliferation of ECV 304 in in vitro culture as well as VEGF-induced proliferation of the cells.
