“…8) The procedure was basically the same as that described previously. 7) Each mouse, naive to the maze, was placed at the end of one arm and allowed to move freely through the maze during an 8-min session. The series of arm entries was recorded visually, and alternation was defined as successive entries into the three arms nonoverlapping triplet sets.…”

“…MC-IXC cells were cultured and maintained according to the previously described methods. 6) The cells, which were obtained from a human neuroblastoma, were grown in Minimum Essential Medium (MEM) containing 15% fetal bovine serum (FBS). The MC-IXC cells were grown in the presence of penicillin (100 U/ml) and streptomycin (0.1 mg/ml) at 37 C, in an atmosphere containing 5% CO 2 .…”

“…The ChAT activity in the MC-IXC cells was measured by a modification of the method described by Fonnum. 7) In the preparation of the enzyme source, the MC-IXC cells were homogenized using a Glass-Col homogenizer (Terre Haute, IN, U.S.A.) with 5 volumes of homogenizing buffer [20 mM Tris-HCl (pH 7.2), containing 150 mM NaCl, 10 mM MgCl 2 , and 0.5% Triton X-100], 6) and centrifuged for 30 min at 10;000 g. The resulting supernatant was then utilized as an enzyme source. All extraction steps were conducted at 4 C. Protein concentrations were measured with a BCA kit (Bicinchoninic acid; Sigma, St. Louis, MO, U.S.A.), using bovine serum albumin (BSA) as the protein standard.…”

“…It has long been recognized as an edible fruit [2]. In addition, various parts of jujubes were reported to be useful for treatment of many symptoms and diseases, for example; diabetes (96% ethanolic extract of Z. jujuba leaves) [3], diarrhea (methanolic extract of Z. mauritiana roots) [4], inhibition of hepatic lipid peroxidation Manuscript (aqueous extract of Z. mauritania leaves) [5], anti-fungal activity (ethanolic extract of Z. jujuba stone) [6] enhancing choline acetyltransferase associated with Alzheimer's disease (methanolic extract of Z. jujuba fruits) [7], anxiolytic effect (methanolic extract of Z. jujuba seed) [8], and enhanced permeability in cell culture monolayer (aqueous extract of Z. jujuba seed) [9]. The active compounds found in jujube were triterpeonic acid (roots) [10], 6'''-feruloylspinosin, 6'''-sinapoylspinosin, jujuboside A, B (seeds) [11], linoleic, oleic and stearic acids (seeds) [12].…”

Abstract-The potential cancer preventive effects of water and ethanolic extracts of three new jujube cultivars were examined in HepG2 and Jurkat cancer cell lines. Apoptosis induction was detected from alteration of nuclei morphology via DAPI staining, and apoptosis death mode was detected via Annexin V-FITC and propidium iodide fluorescence flow cytometry. Results showed that ethanolic jujube seed extracts exhibited antiproliferation only in the Jurkat cell line. Cultivar Taiwan exerted high antiproliferation effect (IC 50 =232.4±7.8 µg/ml) > Jumbo (IC 50 =312.0±18.3 µg/ml) > Rianthong (IC 50 =401.6±9.9 µg/ml), respectively (p<0.05). Melphalan (a positive control) exhibited significant antiproliferation in both HepG2 (IC 50 =37.5±3.9 µg/ml), and Jurkat cell lines (IC 50 =119.1±10.4 µg/ml) but also had cytotoxic effect on the normal Vero cell line (IC 50 =75.0±2.3 µg/ml). Cancer is the severe chronic disease that is found worldwide with increasingly high rate of morbidity and mortality [16]. Therefore, it is of interest to search for cancer preventive agent from natural source. One preferable pharmacodynamic endpoint for cancer treatment is via inducing apoptotic cell death [17]. Hence, apoptosis induction is the primary goal of chemotherapy. Apoptosis is the cell mechanism that balances between cancer cell proliferation and damage irreparable cell including damage DNA. Then, dead cells are phagocytosed by macrophages. The advantage of this death mode does not lead to inflammation in neighboring cells as same as necrosis [17].According to the reports of biological activity of jujubes and new cultivars of Thai jujubes have been cross-bred, this study was aimed to investigate the apoptosis induction effect of the jujube seed extract of three jujube cultivars (i.e., Rianthong, Jumbo and Taiwan) against the human hepatocellular carcinoma HepG2 and human leukemic Jurkat cell lines compared to the normal African green monkey kidney Vero cells. II. MATERIALS AND METHODS A. Plant Materials and ReagentsThe jujube fruits cultivars Rianthong (R), Taiwan (T) and Jumbo (J) were purchased from local markets in Khon Kaen, Thailand in 2012. The Jumbo and Taiwan cultivars are the result of a cross between Z. mauritiana and Z. jujuba, but cultivar (Rianthong) remains unidentified. The cell culture media and fetal bovine serum were purchased from GIBCO, Invitrogen Corporation (USA.). Neutral red dye was purchased from Sigma Chemicals Co. (USA), and melphalan (mel; an apoptosis induction positive control) was bought from Sigma-Aldrich Chemie GmbH (Germany). Apoptotic detection kit was bought from eBiosciences (USA).
