1.A new anti-cancer target: ADAM10
Journal of International Oncology 2011;38(7):492-495
Gene ADAM10 (a disintegrin and metalloproteinase 10) is a member of ADAMs gene family. The corresponding membrane protein contains a disintegrin domain and a metalloproteinase domain. It is involved in various biological events such as cell adhesion, cell fusion, cell migration, and membrane protein shedding and proteolysis. ADAM10 protein is overexpressed in many tumors, which interacts with adhesion molecules and critical signaling molecules associated with cancer development and tumor progression, and promotes tumor invasion and metastasis. Regulating the expression of ADAM 10 can inhibit tumor invasion and metastasis , which may become a new strategy for anticancer therapy.

In order to study the inherent difference among terpenes producing yeasts from the point of metabolomics, we selected taxadiene producing yeasts as the model system. The changes of cellular metabolites during fermentation log phase of artificial functional yeasts were determined using metabolomics methods. The results represented that compared to W303-1A as a blank control, the metabolites in glycolysis, tricarboxylic acid cycle (TCA) cycle and several amino acids were influenced. And due to the changes of metabolites, the growth of cells was inhibited to a certain extent. Among the metabolites identified, citric acid content in taxadiene producing yeasts changed the most, the decreasing amplitude reached 90% or more. Therefore, citric acid can be a marker metabolite for the future study of artificial functional yeasts. The metabolomics analysis of taxadiene producing yeasts can provide more information in further studies on optimization of terpenes production in heterologous chassis.

OBJECTIVE: To study the effects of total saponins of Panax japonicus (TSPJ) on human leukemic HL-60 cells. METHODS: Human leukemic HL-60 cells were cultured in vitro. The cancer cell vigor was detected by using cell counting kit-8. Nitroblue tetrazolium (NBT) was used for measuring cell reduction. The cell cycle and the expression of differentiation antigen CD11b were detected by flow cytometry. RESULTS: Compared with the negative control group, TSPJ in different concentrations could decrease the vigor of HL-60 cells and the number of cells in S phase and up-regulate the CD11b expression, while the numbers of NBT positive cells and cells in G(0)/G(1) phase in the different concentrations of TSPJ-treated groups were increased. CONCLUSION: TSPJ can inhibit the HL-60 cell growth in vitro. Its mechanism may be related to inhibiting proliferation and inducing cell differentiation and cycle arrest.
