OBJECTIVE To study the effects of Fuzheng Yiliu Granule (FZYLG)-medicated serum on apoptosis of liver cancer cells H22 from mice and its mechanism. METHODS Liver cancer cells H22 from mice were incubated in culture media containing sera from rabbits medicated with different doses of FZYLG. Flow cytometry was used to examine the cell cycle and analyze the apoptotic rate of the H22 cells. The m...

β-Elemene is extracted from the Chinese medicinal herb Curcuma Wenyujin. It has a broad-spectrum antitumor effect on many types of cancer. However, the exact mechanism of action of β-elemene in hepatocellular carcinoma (HCC) remains unknown. Histone H1 is thought to act as a repressor of transcription by promoting the compaction of chromatin into higher order structures. We found that histone H...

OBJECTIVES To investigate the radiosensitizing effects of Radix Angelicae Sinensis-Radix Hedysari (RAS-RH [an ultra-filtration extract]) and its underlying mechanisms in human liver cancer cells H22. METHODS This study was conducted between September 2010 and August 2012 in the Gansu University of Traditional Chinese Medicine, Lanzhou, China. The groups were assigned as the control group, dru...

BACKGROUND The previous studies have demonstrated that the polysaccharide isolated from Tarphochlamys affinis (PTA) exhibits anti-tumor effect on S180 tumor-bearing mice and protective effects against hepatic injury. METHODS In this study, we investigated the anti-tumor activity and possible underlying mechanism of PTA on liver cancer using a murine H22 hepatocarcinoma model. RESULTS PTA wa...

BACKGROUND Astragalus polysaccharides (APS) are active constituents of Astragalus membranaceus. They have been widely studied, especially with respect to their immunopotentiating properties, their ability to counteract the side effects of chemotherapeutic drugs, and their anticancer properties. However, the mechanism by which APS inhibit cancer and the issue of whether that mechanism involves t...

BACKGROUND It is widely recognized that astaxanthin (ASX), a member of the carotenoid family, has strong biological activities including antioxidant, anti-inflammation, and immune-modulation activities. Previous studies have confirmed that ASX can effectively inhibit hepatoma cells in vitro. MATERIAL AND METHODS MTT was used to assay proliferation of mice H22 cells, and flow cytometry was used ...

BACKGROUND Alkaloids of Sophora alopecuroides have good biological activity, and are widely used in clinical settings, which not only have pharmacological activities of anti-cancer, cancer suppression, as well as the inhibition, and killing of various microorganisms; but also possess extensive pharmacological effects on immune system, nervous system and cardiovascular system. The objective of t...

Tumor angiogenesis plays an essential role in carcinogenesis, cancer progression, and metastasis. Some studies indicate that lipoxins, endogenous anti-inflammatory lipid mediators, might be involved in tumor angiogenesis; however, the governing mechanisms are still unknown. In the present study, we examined the effects of exogenous lipoxin A(4) (LXA(4)) in mouse hepatocarcinoma cell line (H22) ...

Lentinan could exhibit significant biological activity favorable for human health and disease control such as the recovery of patients with liver cancer. In order to investigate the effect of lentinan dose dependence between immunoprophylaxis and promotion of cancer cell proliferation of the murine liver cancer, different concentrations of lentinan were prepared for the test in vitro (MTT assay...
