Abstract

Liver cancer is one of the most devastating types of cancer worldwide. Despite years of improvements in treatment, the prognosis of patients with this type of malignancy remains poor due to frequent recurrence and metastasis after surgical resection. Ginkgolic acid (GA) is a botanical drug extracted from the seed coat of Ginkgo biloba L. that possesses a wide range of bioactive properties. However, to the best of our knowledge, whether GA can inhibit the invasion of liver cancer cells and the underlying mechanisms remains unknown. The aim of the present study was to investigate the effects of GA on the migration and invasion abilities of liver cancer cells and the underlying molecular mechanism. The results revealed that GA suppressed the migration and invasion abilities of HepG2 cells. In addition, GA treatment inhibited the expression of invasion‑related molecules (MMP‑2 and MMP‑9) and prevented the epithelial‑mesenchymal transition (EMT) of HepG2 cells. Further experiments revealed that GA‑reduced hepatocyte growth factor (HGF) production and suppressed c‑Met phosphorylation may be the underlying mechanisms. Exogenous recombinant HGF supplementation improved the cell invasion ability impaired by GA. Moreover, the in vivo experiment revealed that GA inhibited the tumor growth of liver cancer and prevented EMT. Collectively, these data indicated that GA effectively suppressed the invasion and EMT of HepG2 cells via downregulation of HGF/c‑Met signaling, thus GA may serve as a novel chemotherapeutic agent for the treatment of HCC.
