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.

AIM To prepare naftopidil bioadhesive sustained-release capsule and study their pharmacokinetics and relative bioavailability in the dog. METHODS Bioadhesive polymers such as hydroxypropyl methylcellulse (HPMC) and Carbopol 934 (CP 934) were used in capsule prescriptions. Naftopidil capsule and two formulations of bioadhesive sustained-release capsules (I and II) were given to five healthy male dogs in a cross-over test. The naftopidil concentrations in plasma were determined by a newly developed HPLC method and the pharmacokinetic parameters as well as the relative bioavailability were measured. RESULTS The C0→∞, Cmax and Tmax of naftopidil capsule was (3728±573) h*ng*mL-1, (697±94) ng*mL-1 and (1.2±0.5) h. These parameters of bioadhesive sustained-release capsule I and II, respectively, were (5518±391) h*ng*mL-1 and (5636±427) h*ng*mL-1; (468±61) ng*mL-1 and (512±72) ng*mL-1; both (4.0±0.7) h. Results from statistics showed that there were significant difference between bioadhesive formulations and the non-bioadhesive one in C0→∞, Cmax and Tmax. The bioadhesive formulations and the non-bioadhesive one were not bioequivalent, the relative bioavailability of the two bioadhesive sustained-release capsules were respectively 150%±14% and 154%±23% when compared with the non-bioadhesive capsule. CONCLUSION It is much improving bioavailability of naftopidil by using bioadhesion.

Objective:Hepatocyte growth factor(HGF) speculated to be an endothelial-specific growth factor which protects or repaire the vascular endothelial cells. To test the serum HGF level might be elevated in response to hypertension-induced endothelial cell damage, we measured serum HGF concentrations in normotensive and hypertensive subjects without liver, kidney and other complications.Methods:Eighteen male hypertensive patients and thirteen male normotensive subjects were recruited. All antihypertensive agents were stopped for 2 weeks before the study. The serum HGF concentrations were measured by a specific enzyme-linked immunosorbent assay (ELISA). Results:Serum HGF concentrations were 0.32±0.13 ng/ml in normotensive subjects and 0.37±0.27 ng/ml in hypertensive patients. No significant difference between the two groups(P>0.05) was found. Systolic, mean and diastolic blood pressure did not show any correlation with serum HGF concentrations.Conclusions:This study showed that serum HGF levels did not be increased in male patients with mild to moderate hypertension. Although local HGF is produced rapidly because of the damage of endothelial cells by high blood pressure, the circulating level of HGF did not represent the local changes of HGF production.
