Tanshinol inhibits the growth, migration and invasion of hepatocellular carcinoma cells via regulating the PI3K-AKT signaling pathway.

ABSTRACT: Background:Tanshinol is an active constituent of Salvia miltiorrhiza and possess anti-inflammatory, antioxidant, and anti-bacterial activity. Herein, we explored the role of tanshinol on the growth and aggressiveness of hepatocellular carcinoma (HCC) cells in vitro and in vivo. Materials and methods:The proliferation of a panel of HCC cell lines was measured using MTT assay. The expressions of phosphatidylinositol 3 kinase (PI3K) and protein kinase B (AKT) were detected by immunofluorescence staining and immunohistochemical assay. The levels of Bcl-2 and Bax were determined using immunoblotting assay. The secretions of matrix metalloproteinase-2 (MMP-2) and MMP-9 were detected by ELISA. The migration and invasion abilities of HepG2 cell were determined using wound healing and Transwell invasion assays. The apoptosis of HepG2 cell induced by tanshinol was analyzed by Annexin V/propidium iodide staining. A xenograft model was constructed to investigate the inhibitory effect of tanshinol on HepG2 cell growth in vivo. To further investigate the role of tanshinol on the metastasis of HepG2 cell in vivo, an experimental metastasis assay was performed. Results:Tanshinol inhibited the growth and colony formation of HCC cell in vitro. Tanshinol also induced the apoptosis of HepG2 cell and inhibited the migration and invasion of HepG2 cell. In in vivo experiments, tanshinol suppressed the tumor growth and metastasis of HepG2 cell. Furthermore, the phosphorylation of PI3K and AKT was decreased by tanshinol in vitro and in vivo. Conclusion:Tanshinol exerts its anti-cancer effects via regulating the PI3K-AKT signaling pathway in HCC.

Project description:Esophageal squamous cell carcinoma (ESCC) is a lethal disease due to its high aggressiveness. The aim of the present study was to investigate the role of xeroderma pigmentosum complementation group D (XPD) in the growth and invasion of ESCC and to elucidate the potential underlying molecular mechanisms. Western blot analysis and RT‑qPCR were used to detect the expression level of XPD in ESCC tissue samples and adjacent normal esophageal tissue samples. The pEGFP‑N2/XPD plasmid was transfected into human ESCC cell lines (EC9706 and EC109). The proliferation, apoptosis, migration and invasion of EC9706 or EC109 cells were assessed following transfection with the XPD overexpression plasmid. The chemosensitivity of EC9706 or EC109 cells to cisplatin or fluorouracil was evaluated by CCK‑8 assay. The expression levels of phosphoinositide 3‑kinase (PI3K)/AKT, nuclear factor (NF)‑κB, Janus kinase 2 (JAK2)/signal transducer and activator of transcription 3 (STAT3) and mitogen‑activated protein kinase (MAPK) signaling pathway‑related genes were detected by RT‑qPCR and western blot analysis. The results demonstrated that the expression level of XPD was markedly lower in ESCC tissue samples than in adjacent normal esophageal tissue samples. The pEGFP‑N2/XPD plasmid was successfully transfected into EC9706 or EC109 cells, inducing XPD overexpression. A High XPD expression markedly suppressed cell proliferation, migration and invasion, and increased the apoptotic rate of EC9706 and EC109 cells. Furthermore, the overexpression of XPD significantly increased the chemosensitivity of EC9706 and EC109 cells to cisplatin or fluorouracil. Following XPD overexpression, the expression levels of PI3K, p‑AKT, c‑Myc, Cyclin D1, Bcl‑2, vascular endothelial growth factor (VEGF) and matrix metalloproteinase (MMP)‑9 were markedly downregulated, while the expression level of p21 was markedly upregulated. On the whole, the findings of the present study demonstrate that XPD inhibits the growth and invasion of EC9706 and EC109 cells, whilst also enhancing the chemosensitivity of EC9706 and EC109 cells to cisplatin or fluorouracil by regulating the PI3K/AKT signaling pathway. XPD may thus be an underlying target for ESCC treatment and drug resistance.
