Inhibitory effect of zileuton on growth of pancreatic cancer cell lines / 中国实用内科杂志

ABSTRACT

Objective To investigate the 5-lipoxygenase(5-LOX)expression in human pancreatic cancer cells and the inhibitory effect on growth of SW1990 by selective 5-LOX inhibitor zileuton in vitro.Methods The 5-LOX expression in pancreatic cancer cell was defected by immunocytochemistry and RT-PCR form May 10,2003 to May 25,2004.MTT and flow cytometry with AnnexinⅤ-FITC and propidium iodide(PI)staining and acridine orange(AO)staining were used to observe the effect of zileuton on the growth of SW1990cell line.Results The 5-LOX mRNA and protein expression was detectable in pancreatic cancer cell line by mmunohistochemistry and RT-PCR technique respectively.Zileuton could inhibit the growth of SW1990 cell line in a time-and dose-dependent manner.Conclusion Zileuton might inhibit the growth of SW1990 cell line in a time-and dose-dependent manner.
