摘要:
The present invention relates to methods for identifying compounds capable of modulating a cellular response. The methods involve attaching living cells to solid supports comprising a library of test compounds. Test compounds modulating a cellular response, for example via a cell surface molecule may be identified by selecting solid supports comprising cells, wherein the cellular response of interest has been modulated. The cellular response may for example be changes in signal transduction pathways modulated by a cell surface molecule.
摘要:
The present invention relates to compounds capable of inhibiting binding of the Smac protein to Inhibitors of apoptosis (IAPs). Such compounds are preferably capable of inhibiting IAP and thus may promote apoptosis or sensitize cells for apoptosis. The compounds may be used in the treatment of proliferative diseases, such as cancer.
摘要:
A novel intracellular signalling activity of coagulation factor VII (FVII) in cells expressing tissue factor (TF) is described. The present invention relates to use of FVIIa or another TF agonist, or FVIIai or another TF antagonist for the preparation of a medicament for modulation of FVIIa-induced activation of the MAPK signalling pathway in a patient. Moreover the present invention relates to a method of treatment, and a method of detecting the activity of compounds, in particular drug candidates, that interact with the FVIIa mediated intracellular signalling pathway.
摘要:
A method and apparatus for screening an array of test compounds for bioactivity by contacting an array of test compounds with a detector layer capable of detecting bioactivity, and detecting a detector layer response. The detector layer is comprised of physiologically viable cells. The method and apparatus allow a large number of test compounds to be simultaneously assayed in parallel without the need for complex fluidic devices.
摘要:
The present invention relates to a method of detecting biologically active substances affecting intracellular processes, an isolated DNA, a vector and a cell for use in the method. More specifically, the present invention provides a method for detecting a biologically active substance that affects intracellular processes mediated through a protein kinase or a second messenger, which comprises incubating a cell with a test substance and measuring any change caused by the test substance in the flourescence of (i) a wild-type or modified green flourescent protein (GFP) having a protein kinase recognition site, (ii) a modified GFP containing a second messenger binding domain, or (iii) a hybrid polypeptide having a wild-type or modified GFP and an attached protein kinase recognition site or a second messenger binding domain.
摘要:
The present invention provides methods for modifying the motility of tissue factor (TF)-expressing cells, which are carried out by contacting such cells with an effective amount of Factor VIIai Factor VIIa agonist.
