Abstract
Hepatocellular carcinoma (HCC) is the most prevalent primary liver cancer with limited treatment options. Lobetyolin (LBT), a polyacetylene glycoside mainly extracted from the roots of Codonopsis pilosula, has been reported to have anti-tumor efficancy in various cancers. However, the role of LBT as well as its underlying mechanisms in HCC remain unclear. Here we investigated the impact of LBT on the phenotype in HepG2 and Huh7 cells. We found that LBT significantly induced cell growth inhibition and mitochondria-dependent apoptosis in HCC cells. Moreover, LBT upregulated dual specificity phosphatase-1 (DUSP1) expression and knockingdown DUSP1 markedly attenuated those effects induce by LBT. Meanwhile, LBT decreased the phosphorylation level of extracellular signal-regulated kinase 1/2 (ERK1/2), a well-recognized downstream effector of DUSP1, and knockingdown DUSP1 partially recovered LBT-induced inactivation of ERK1/2. In conclusion, the present study indicated that LBT could induce cell death of HCC via promotion of DUSP1-mediated ERK1/2 inhibition. These data will help to establish the evidence of LBT to treat HCC.
期刊介绍:
Biological and Pharmaceutical Bulletin (Biol. Pharm. Bull.) began publication in 1978 as the Journal of Pharmacobio-Dynamics. It covers various biological topics in the pharmaceutical and health sciences. A fourth Society journal, the Journal of Health Science, was merged with Biol. Pharm. Bull. in 2012.
The main aim of the Society’s journals is to advance the pharmaceutical sciences with research reports, information exchange, and high-quality discussion. The average review time for articles submitted to the journals is around one month for first decision. The complete texts of all of the Society’s journals can be freely accessed through J-STAGE. The Society’s editorial committee hopes that the content of its journals will be useful to your research, and also invites you to submit your own work to the journals.
