Crude extract of J1 fermentation promotes apoptosis of cervical cancer cells

Abstract

Cervical cancer is a typical cancer characterized by abnormal cell growth in the cervical area. Ginkgo biloba L. is a deciduous tree of the genus Ginkgo, possessing anti-cancer effects. The aim of this study was to explore the effect of strain J1 from Ginkgo biloba L. on apoptosis of cervical cancer cells. Bacteriostatic activity test, MTT assay and Flow cytometry were used in this study. Crude extract of J1 fermentation reduced cell growth in cervical cancer. The crude extract of the fermentation broth of strain J1 had a good inhibitory effect on Staphylococcus aureus. The crude extract of the J1 fermentation had no toxic effect on normal WISH cells in the range of anti-cervical cancer concentration. Crude extract of J1 fermentation induced apoptosis and regulated cell cycle in cervical cancer. The active compounds were separated and identified by preparative chromatography, and more than ten compounds were obtained. Our study suggests that the crude extract of J1 fermentation from Endophytic fungi of Ginkgo biloba reduced cell growth, and promoted apoptosis of cervical cancer, and is a potential therapeutic strategy for the treatment of cervical carcinoma.
