Ponicidin inhibits pro-inflammatory cytokine TNF-α-induced epithelial-mesenchymal transition and metastasis of colorectal cancer cells via suppressing the AKT/GSK-3β/Snail pathway.
    Inflammopharmacology, 2019, Volume: 27, Issue:3

    Ponicidin (PON), a natural diterpenoid compound, has been shown to exhibit potent anticancer activities in a wide variety of cancers, including colorectal cancer (CRC). Nevertheless, the precise mechanisms underlying the anti-metastasis effect of PON have not yet been completely defined. The present study was designed to uncover the inhibitory effect of PON on epithelial-mesenchymal transition (EMT), migration and invasion of HCT116 cells induced by pro-inflammatory cytokine tumor necrosis factor-α (TNF-α) in vitro, and liver metastasis in vivo. Briefly, cell proliferation was assessed by Cell Counting Kit-8 assay, followed by wound healing and transwell assays to evaluate cell migration and invasion. The EMT-related molecular markers were determined through quantitative real-time polymerase chain reaction (qPCR), immunofluorescence (IF), western blot (WB), and immunohistochemistry (IHC). Additionally, WB was used to assess the expression of AKT, phosphorylated AKT (p-AKT), GSK-3β, and phosphorylated GSK-3β (p-GSK-3β). As a result, PON could effectively suppress EMT, migration, and invasion in HCT116 cells in vitro, and liver metastasis of HCT116 cells in vivo. Additionally, PON administration also dramatically altered the expression of EMT-associated markers such as E-cadherin, N-cadherin, and Vimentin, and suppressed the expression of p-AKT, p-GSK-3β and transcription factor, Snail in a dose-dependent manner. Moreover, the incidence of liver metastasis in the control group was 100% and although the incidence of liver metastasis did not decrease, the number of metastatic nodules in the livers of each PON dose group decreased by (34 ± 4.2)%, (64 ± 3.6)%, and (76 ± 5.3)%, respectively, compared to the control group. Collectively, these findings indicated that targeting the AKT/GSK-3β/Snail pathway by PON might be a promising treatment for TNF-α-induced EMT and metastasis of CRC.

Ponicidin inhibits cell growth on hepatocellular carcinoma cells by induction of apoptosis.
    Digestive and liver disease : official journal of the Italian Society of Gastroenterology and the Italian Association for the Study of the Liver, 2007, Volume: 39, Issue:2

    Ponicidin is recently reported to have anti-tumour effects on a large variety of cancers. The present study was undertaken to investigate the anti-proliferation effects of ponicidin on hepatocellular carcinoma cells and its mechanism.. Two hepatocellular carcinoma cell lines, QGY-7701 and HepG-2 cells, were used. Cell viability was measured by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay. Cell apoptosis was assessed by flow cytometry and deoxyribonucleic acid fragmentation analysis. Cell morphology was observed by Hoechst 33258 staining. Reverse transcriptase-polymerase chain reaction and Western blot analysis were used to detect Survivin as well as Bax and Bcl-2 expressions.. Ponicidin could inhibit the growth of QGY-7701 and HepG-2 cells significantly by induction of apoptosis. Marked morphological changes of apoptosis were observed clearly. Both Survivin and Bcl-2 expressions were down-regulated remarkably while Bax expression up-regulated when apoptosis occurred.. Ponicidin has significant anti-proliferation effects by inducing apoptosis on hepatocellular carcinoma cells in vitro, down regulation of Survivin and Bcl-2 as well as upregualation of Bax expressions may be the important apoptotic inducing mechanisms.
