Abstract
Agaricus blazei Murill (AbM) is a mushroom belonging to the Basidiomycetes family, which is believed to have antitumor and antioxidative activities. Proteoglycans and ergosterol are considered the key compounds of AbM for antitumor properties and so are used in complementary and alternative medicine as an anticancer drug. AbM is used to avoid serious side effects that would inevitably affect patients. Currently, the efficacy of AbM against chronic myeloid leukemia (CML) has not been established. The present study aimed to investigate the antitumor activities of the acidic RNA protein complex, FA-2-b-β, extracted from wild edible AbM. The CML K562 cells or primary CML bone marrow (BM) cells were treated with FA-2-b-β at different concentrations and time points. CML cell line proliferation and apoptosis were determined using the CCK-8 assay or Annexin V/propidium iodide (PI) labeling, RT-qPCR and western blotting was performed to determine the involvement of the Wnt/β-catenin-associated apoptotic pathway. The results of the present study demonstrated that FA-2-b-β has a high anti-proliferative potency and strong pro-apoptotic effects. Thus, daily intake of mushrooms containing FA-2-b-β may be an adequate source as an alternative medicine in the management of CML, and may provide useful information for the development of a novel therapeutic target in this area.

Abstract
Context Previous studies have demonstrated that 3′-azido-3′-deoxythymidine (AZT) and arsenic trioxide (As2O3), traditional chemotherapy agents, can synergically inhibit the growth of hepatocellular carcinoma cells. However, the molecular mechanisms underlying As2O3 and AZT anti-hepatoma activity are unknown. Objective This study aimed to investigate the role of early growth response protein 1 (Egr-1) in the process of As2O3 combined with AZT inhibiting proliferation and inducing apoptosis of human hepatocellular carcinoma HepG2 cells, and explore the possible mechanism. Materials and methods The expression of Egr-1 was silenced using siRNA, and then HepG2 cells were treated with As2O3 (2 μM) and AZT (20 μM). The rates of cell inhibition and apoptosis were determined by the 3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazoliumbromide (MTT) method and flow cytometry, respectively. The mRNA and protein expression of p53, caspase-3, and Egr-1 were detected by real-time quantitative polymerase chain reaction and Western blotting, respectively. Results The inhibitory rate of As2O3 (2 μM) combined with AZT (20 μM) on proliferation of HepG2 cells was significantly higher than that of As2O3 alone. The combination index (CI) values were 0.2<CI<0.4, showing strong synergic effect. After silencing Egr-1, the proliferation inhibition and proapoptotic ability of As2O3 combined with AZT on HepG2 cells were decreased, and the CI value was greater than 1, showing antagonistic effect. In addition, the expression of p53 and caspase-3 mRNA/protein was also significantly decreased. Conclusion The present results show that AZT could increase the sensitization of As2O3 for inhibiting proliferation and promoting apoptosis of HepG2 cells through regulating the expression of Egr-1, which may control the expression of p53 and caspase-3.

Abstract
Esophageal cancer is one of the most common type of malignancies. Telomerase activity, which is absent or weakly detected in the majority of human somatic cells, is elevated in esophageal cancer. Although azidothymidine (AZT), a reverse transcriptase inhibitor, has been utilized as a treatment for tumors, its role in treating esophageal cancer has not been confirmed. The aim of the present study was to determine the effect of AZT on telomerase activity and the proliferation of the human esophageal cancer cell line TE-11. A telomeric repeat amplification assay was utilized to detect telomerase activity following treatment of TE-11 cells with AZT. The effect of AZT on TE-11 cell cycle distribution was determined by flow cytometry. Cellular DNA damage was evaluated by a comet assay and an MTT assay demonstrated that AZT significantly inhibited the viability of TE-11 cells, in a time-and dose-dependent manner. In addition, TE-11 cells treated with various concentrations of AZT exhibited a significant reduction in telomerase activity and percentage of cells in the G1/G0 phase, and an increase in the percentage of cells in the S phase. High doses of AZT caused DNA damage, and enhanced the expression levels of γ-H2A histone family member X and phosphorylated checkpoint kinase 2 in TE-11 cells. These results demonstrated that AZT effectively inhibits proliferation of the TE-11 human esophageal cancer cell line in vitro. The growth inhibitory effects were associated with a reduction in telomerase activity, S and G2/M phase cell cycle arrest, and enhanced DNA damage, suggesting that AZT may be utilized in the clinic for the treatment of esophageal cancer.

Abstract
Many mushrooms have been used as foods and medicines for a long time. Mushrooms contain polyphenols, polysaccharides, vitamins and minerals. Studies show that mushrooms possess various bioactivities, such as antioxidant, anti-inflammatory, anticancer, immunomodulatory, antimicrobial, hepatoprotective, and antidiabetic properties, therefore, mushrooms have attracted increasing attention in recent years, and could be developed into functional food or medicines for prevention and treatment of several chronic diseases, such as cancer, cardiovascular diseases, diabetes mellitus and neurodegenerative diseases. The present review summarizes the bioactivities and health benefits of mushrooms, and could be useful for full utilization of mushrooms.

Abstract
OBJECTIVE To observe the effects of water extract of Zuojin Pill ([characters: see text], ZJP) on inhibiting the growth of human gastric cancer cell line SGC-7901 and its potential mechanism. METHODS Effects of ZJP on SGC-7901 cells growth were determined by 3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl-2-H-tetrazolium bromide (MTT) assay, cell apoptosis and cell cycle were determined by flow cytometry, and apoptosis induction was detected by means of DNA gel electrophoresis. The cellular mechanism of drug-induced cell death was unraveled by assaying oxidative injury level of SGC-7901 cell, mitochondrial membrane potentials, expression of apoptosis-related genes, such as B cell lymphoma/lewkmia-2 (Bcl-2), Bcl-2 associated X protein (Bax) and cleaved caspase-3 and caspase-9. RESULTS ZJP exerted evident inhibitory effect on SGC-7901 cells by activating production of reactive oxygen species and elevating Bax/Bcl-2 ratio in SGC-7901 cells, leading to attenuation of mitochondrial membrane potential and DNA fragmentation. CONCLUSIONS ZJP inhibits the cancer cell growth via activating mitochondria-dependent apoptosis pathway. ZJP can potentially serve as an antitumor agent.

Abstract
Zidovudine, a drug widely used in the treatment of AIDS, has been shown to influence cytosolic calcium activity in HIV-infected lymphocytes. Thus, zidovudine may modify the activity of Ca(2+)-permeable ion channels. In erythrocytes, activation of Ca(2+)-permeable cation channels stimulates eryptosis, the suicidal erythrocyte death. Eryptosis is characterized by cell shrinkage (apparent from a decrease of forward scatter) and phosphatidylserine (PS) exposure (apparent from annexin V-binding) at the erythrocyte surface. Triggers of eryptosis include isotonic cell shrinkage (Cl(-) replacement by gluconate), energy depletion (removal of glucose) or exposure to a variety of drugs including azathioprine. The present study explored, whether zidovudine influences the activity of erythrocytic Ca(2+)-permeable cation channels and eryptosis. Whole-cell patch-clamp recordings indeed revealed that zidovudine blocked the Ca(2+)-permeable cation channels activated by Cl(-) removal. In the presence of Cl(-) and glucose, the percentage of annexin V-binding cells was low and not significantly modified by the presence of zidovudine. Both, Cl(-) removal and glucose depletion increased annexin V-binding and decreased forward scatter, effects significantly blunted by zidovudine (2 microg/ml). According to Fluo3 fluorescence, zidovudine (2 microg/ml) did not significantly modify cytosolic Ca(2+) concentration under control conditions, but significantly blunted the increase in cytosolic Ca(2+) activity following glucose depletion. Furthermore, zidovudine significantly inhibited azathioprine-induced eryptosis. The present observations disclose a completely novel effect of zidovudine, i.e. its inhibitory influence on Ca(2+) entry and subsequent suicidal erythrocyte death during isotonic cell shrinkage or energy depletion.
