  • Alpha Phellandrene induced apoptosis in mice leukemia wehi 3 cells in vitro
    Environmental Toxicology, 2016
    Co-Authors: Kung Wen Lu, Yi Shih, Chih Chung Wu, Hsu Feng Lu, Jawchyun Chen, Ping Ping Wu, Jing Gung Chung

    Abstract:

    : Although reports have shown that α-Phellandrene (α-PA) is one of the monoterpenes and is often used in the food and perfume industry, our previous studies have indicated that α-PA promoted immune responses in normal mice in vivo. However, there is no available information to show that α-PA induced cell apoptosis in cancer cells, thus, we investigated the effects of α-PA on the cell morphology, viability, cell cycle distribution, and apoptosis in mice leukemia WEHI-3 cells in vitro. Results indicated that α-PA induced cell morphological changes and decreased viability, induced G0/G1 arrest and sub-G1 phase (apoptosis) in WEHI-3 cells. α-PA increased the productions of reactive oxygen species (ROS) and Ca2+ and decreased the levels of mitochondrial membrane potential (ΔΨm ) in dose- and time-dependent manners in WEHI-3 cells that were analyzed by flow cytometer. Results from confocal laser microscopic system examinations show that α-PA promoted the release of cytochrome c, AIF, and Endo G from mitochondria in WEHI-3 cells. These results are the first findings to provide new information for understanding the mechanisms by which α-PA induces cell cycle arrest and apoptosis in WEHI-3 cells in vitro. © 2015 Wiley Periodicals, Inc.

  • Alpha Phellandrene induced dna damage and affect dna repair protein expression in wehi 3 murine leukemia cells in vitro
    Environmental Toxicology, 2015
    Co-Authors: Chih Chung Wu, Yi Shih, Shuwen Weng, Yiping Huang, Jing Gung Chung

    Abstract:

    Although there are few reports regarding α-Phellandrene (α-PA), a natural compound from Schinus molle L. essential oil, there is no report to show that α-PA induced DNA damage and affected DNA repair associated protein expression. Herein, we investigated the effects of α-PA on DNA damage and repair associated protein expression in murine leukemia cells. Flow cytometric assay was used to measure the effects of α-PA on total cell viability and the results indicated that α-PA induced cell death. Comet assay and 4,6-diamidino-2-phenylindole dihydrochloride staining were used for measuring DNA damage and condensation, respectively, and the results indicated that α-PA induced DNA damage and condensation in a concentration-dependent manner. DNA gel electrophoresis was used to examine the DNA damage and the results showed that α-PA induced DNA damage in WEHI-3 cells. Western blotting assay was used to measure the changes of DNA damage and repair associated protein expression and the results indicated that α-PA increased p-p53, p-H2A.X, 14-3-3-σ, and MDC1 protein expression but inhibited the protein of p53, MGMT, DNA-PK, and BRCA-1. © 2014 Wiley Periodicals, Inc.

  • Alpha Phellandrene a natural active monoterpene influences a murine wehi 3 leukemia model in vivo by enhancing macrophague phagocytosis and natural killer cell activity
    in Vivo, 2014
    Co-Authors: Kung Wen Lu, Yi Shih, Chih Chung Wu, Hsu Feng Lu, Ping Ping Wu, Nou Ying Tang, Jing Gung Chung

    Abstract:

    : α-Phellandrene (α-PA), a cyclic monoterpene, is a natural compound reported to promote immune responses in normal BALB/c mice. The effects of α-PA on immune responses in a leukemia mouse model were examined. Mice were injected with mouse leukemia WEHI-3 cells and subsequently treated orally with or without α-PA (0, 25 and 50 mg/kg) and olive oil as positive control for two weeks. Leukocytes and splenocytes were isolated and cell markers for CD3, CD19, CD11b and Mac-3, phagocytosis and natural killer cell cytoxicity effects were analyzed by flow cytometry. α-PA increased the percentage of CD3 (T-cell marker), CD19 (B-cell marker) and MAC3 (macrophages) markers but reduced the percentage of CD11b (monocytes) cell surface markers. α-PA (25 and 50 mg/kg) increased phagocytosis of macrophages from blood samples and treatment promoted natural killer cell activity at 25 mg/kg from splenocytes. α-PA at 25 mg/kg also increased B- and T-cell proliferation.
