Effects of five prescriptions in Synopsis of Golden Chamber on the malignant phenotype and expression of CA125, CEA, HE4 proteins in human ovarian cancer cells.

Abstract

e17546 Background: Ovarian cancer(OC) is a common gynecological tumor with characteristics of low early diagnosis rate, late lack of effective treatment and high mortality. It is an important problem to find new effective treatment for ovarian cancer. Synopsis of the Golden Chamber is the miscellaneous diseases part of Treatise on Typhoid and Miscellaneous Diseases written by Zhang Zhongjing, a famous medical expert in Eastern Han Dynasty of China, and is also the earliest classical treatise on diagnosis and treatment of miscellaneous diseases, which records 205 prescriptions. This study aims to screen out formula with strong inhibitory effects on OC from 205 prescriptions of Synopsis of the Golden Chamber , and investigate the effects of screened prescriptions in Synopsis of the Golden Chamber on human ovarian cancer cell malignant phenotype and CA125, CEA and HE4 proteins expression. Methods: MTT method was applied to screen out the best effective prescription and determine the IC50 value of prescription on ovarian cancer ES-2 and OV-1063 cells. The effects of screened prescriptions on the proliferation, migration, invasion, cloning ability, cell cycle and CA125, CEA and HE4 proteins expression of ES-2 and OV-1063 cells were investigated by MTT assay, RTCA assay, soft agar assay, flow cytometry and western blot analysis. Results: Guizhi Fuling Pill, Dachaihu Decoction, Xuanfuhua Decoction, Baitouweng Decoction and Bentun Decoction were screened out, which all could obviously inhibit the proliferation of ES-2 and OV-1063 cells with dose-effect and time-dependent manner. The IC50 values of Guizhi Fuling Pill, Dachaihu Decoction, Xuanfuhua Decoction, Baitouweng Decoction and Bentun Decoction for ES-2 cell were 636.476, 315.859, 24.357, 9.519, 96.533μg/ml respectively; for OV-1063 were 403.119, 225.176, 12.977, 9.256, 115.86μg/ml respectively. The five prescriptions all significantly affected the cell morphology, proliferation, migration, invasion, cloning ability, cell cycle of ES-2 and OV-1063 cells. The five prescriptions all could decreased the protein expression levels of CA125 and CEA in ovarian cancer OV-1063 cells, while Guizhi Fuling Pill, Dachaihu Decoction, Xuanfuhua Decoction and Baitouweng Decoction decreased the expression of HE4 protein in OV-1063 cells. Conclusions: The five prescriptions in Synopsis of the Golden Chamber can inhibit the malignant phenotype of ovarian cancer, which may be related to the inhibition of CA125, CEA and HE4 proteins expression.
