Abstract

Background: Hepatic cancer is the most common primary liver malignancy, with high incidence and mortality worldwide. Atractylon is an active constituent isolated from Atractylodes lancea (Thunb.) DC. and Atractylodes chinensis (DC.) Koidz., which proved to have multiple activities. Methods: In this study, we evaluated the antihepatic cancer (HCC) effect of atractylon in vitro and in vivo and investigated its underlying mechanism. Cell proliferation, colony formation, cell apoptosis, migration and invaison and was identified by MTT, crystal violet staining, flow cytometry analysis, and Transwell assay. The ∆Ψm of HepG2 and MHCC97H cells were detected by Rhodamine 123. The ROS level was determined by 2,7-Dichlorodi-hydrofluorescein diacetate (DCFH-DA) method. Protein expression was identified by Western blot analysis. The anti-HCC effect of atractylon in vivo was evaluated by a subcutaneous tumor model. Results: The results suggested that atractylon significantly inhibits the proliferation and promotes apoptosis of hepatic cancer cell lines, including HepG2, SMCC7721, and MHCC97H. Moreover, the results showed that atractylon reduces the mitochondrial membrane potential (∆Ψm), increases ROS level, inhibits the expression of Bcl-2,...Continue Reading

Apoptosis in Cancer

Apoptosis is an important mechanism in cancer. By evading apoptosis, tumors can continue to grow without regulation and metastasize systemically. Many therapies are evaluating the use of pro-apoptotic activation to eliminate cancer growth. Here is the latest research on apoptosis in cancer.

Cell Migration

Cell migration is involved in a variety of physiological and pathological processes such as embryonic development, cancer metastasis, blood vessel formation and remoulding, tissue regeneration, immune surveillance and inflammation. Here is the latest research.

Apoptosis

Apoptosis is a specific process that leads to programmed cell death through the activation of an evolutionary conserved intracellular pathway leading to pathognomic cellular changes distinct from cellular necrosis

Cell Migration in Cancer and Metastasis

Migration of cancer cells into surrounding tissue and the vasculature is an initial step in tumor metastasis. Discover the latest research on cell migration in cancer and metastasis here.
