Methods： Cell adhesion assay was used to observe the effect of rAdinbitor on the adhesion of 8MMC-7721 cells to fibronectin （FN）. Crystal violet staining was performed to detect the influence of rAdinbitor on the adhesion of 8MMC- 7721 cells. MTT assay was employed to detect the inhibitory effects of different concentration of rAdinbitor on the proliferation of 8MMC-7721 cells. The morphologic changes of the control 8MMC-7721 cells and the apoptotic cells induced by 200μg/mL rAdinbitor for 36 h were observed under light microscope after HE staining. Flow cytometry analysis was applied to determine the apoptosis rate of 8MMC-7721 cells. Results： （1） FN promoted the adhesion of human hepatoma cell strain 8MMC-7721 in a dose-dependent manner. （2） rAdinbitor could dose-dependently inhibit the adhesion of SMMC-7721 cells to FN. The higher the concentration was, the stronger the inhibition was. There was significant difference among the groups （P 〈 0.05）. （3） rAdinbitor had a strong inhibition on the proliferation of 8MMC-7721 cells and showed a dose-dependent manner （P 〈 0.05）. After a 48 h exposure, the IC50 value of rAdinbitor was 177.83 μg/mL. （4） After exposure of 8MMC-7721 cells to 200μg/mL rAdinbitor for 36 h, the early morphologic changes appeared and the apoptosis rate was 20.68%, significantly higher than that of the control group （2.38%, P 〈 0.05）. Conclusion： rAdinbitor can dose-dependently inhibit the 8MMC-7721 cells adhesion to FN, and can inhibit the proliferation in dose-dependent manner and promote their apoptosis.展开更多

Such a structure is generated based on the proliferation and differentiation of neural stem/progenitor cells. Notch functions as a molecular switch for neural stem/progenitor cell fate during cortex development but the mechanism remains unclear. Biochemical and cellular studies showed that Notch receptor activation induces several proteases to release the Notch intracellular domain （NICD）. A Disintegrin and Metalloprotease 10 （ADAM10） might be a physiological rate-limiting $2 enzyme for Notch activation. Nestin-driven conditional ADAM10 knockout in mouse cortex showed that ADAM10 is cdtical for maintenance of the neural stem cell population during early embryonic cortex development. However, the expression pattern and function of ADAM10 during later cerebral cortex development remains poorly understood. We performed in situ hybridization for ADAMIO mRNA and immunofluorescent analysis to determine the expression of ADAM10 and NICD in mouse cortex from embryonic day 9 （E14.5） to postnatal day 1 （P1）. ADAM10 and NICD were highly co-localized in the cortex of E16.5 to P1 mice. Comparisons of expression patterns of ADAM10 with Nestin （neural stem cell marker）, Tujl （mature neuron marker）, and S100β （gila marker） showed that ADAM10 expression highly matched that of S10013 and partially matched that of Tujl at later embryonic to early postnatal cortex developmental stages. Such expression patterns indicated that ADAM10-Notch signaling might have a critical function in neuronal maturation and gliogenesis during cortex development.展开更多

The venom of M. raddei was separated by reverse phase high-performance liquid chroma-tography (RP HPLC), and individual fractions were analyzed for disintegrin activity. Disintegrin-like components from the venom of M. raddei, by blocking integrins on breast cancer cells (MDA-MB-435), not only interferes with adhesion of breast cancer cells to the extracellular matrix, but also inhibits cellular mobility which is essential for cancer invasion. These effects seriously curtail the metastatic capability of the MDA-MB-435 cells.展开更多

In particular, integrin alphavbeta3 recognizes the RGD motif as a ligand-binding site on various extracellular molecules of the extracellular matrix. Integrin aphavbeta3 has been associated with high malignant potential in breast cancer cells, and has signalized the onset of widespread metastasis. In recent years, several antagonists of integrin alphavbeta3, including snake venom disintegrins, have been used as potential anti-cancer agents. In the present work, the effect of contortrostatin, a disintegrin isolated from the venom of the snake Agkistrodon contortrix, was studied on primary cultures of human breast cancer cell. Scanning and transmission electron microscopy were employed in order to examine alterations in cell morphology and fluorescent microscopy and visualize changes in distribution of integrin alphavbeta3 and talin. Fluorescent localization of caspase 8 was made in order to visualize any sign of proapoptotosis and western immunoblotting of integrin, talin and annexin was undertaken in order to identify changes. The results suggest that the snake venom contortrostatin seriously affects cell morphology, adhesion and mobility and induces breast cancer cells to apoptosis.展开更多

Thus it is very interesting and instructive to study the underlying regulatory mechanism for VR. Recently, evidenceI suggests that tumor necrosis factor-α （TNF-α） activity can independently influence VR, and aggravate myocardial dysfunction and cell death in the ventricle. The activation of pro-TNF〈t is adjusted by a disintegrin metalloproteinase （ADAM） 10 and ADAM17, the latter might take part in extracellular matrix （ECM） modulation in the borderline region of cardiac infarction.2 However, little is known about the relationship between ADAMsl0, 17 expressions and TNF-α activity in the process of VR after MI. The present study tested the hypothesis in rats that the interaction between ADAMsl0, 17 expressions and TNF-α activity was a contributory mechanism for VR of the healing myocardium, and metoprolol treatment might ameliorate VR inhibiting the mechanism.展开更多
