The present invention relates to the use of ZnT-1, originally described as a zinc transporter, in the regulation of L-type calcium channels (LTCC). In this study, the inventors have unexpectedly demonstrated that ZnT-1 physically interacts with LTCC, regulating its function. Most importantly, the inventors have shown that ZnT-1 can regulate intracellular Ca2+ influx, and thus, its intracellular concentration. This is the first demonstration of a natural blocker for LTCC, and it is a promising breakthrough as a potential agent to be used in the treatment and/or prevention of cardiovascular diseases and related indications.
摘要:
Polypeptides comprising all or part of a variant integrin α subunit A domain and its flanking region are described. In solution or in membrane-associated form, the A domain polypeptides of the invention exists predominantly in a high affinity conformation. In the polypeptides of the invention, referred to as variant integrin polypeptides, a crucial isoleucine or glutamic acid residue is altered. For example, the glutamic acid can be either deleted or replaced with different amino acids residue, e.g., glutamine, aspartic acid, or alanine. The variant integrin polypeptides of the invention selectively impair binding or activation-dependent ligands, but not independent ligands. They are useful in screening assays for the identification of molecules that enhance binding of variant polypeptides with impaired binding. In addition, they are useful in distinguishing between activation-dependent ligands and activation-independent ligands. They are also useful for generating antibodies, e.g., monoclonal antibodies, which bind to the impaired form of an integrin. Some such antibodies recognize an epitope that is either not present or not accessible on an integrin that is in the high affinity conformation. The variant integrin polypeptides of the invention can be derived from any integrin α subunit that could be used therapeutically.

The relation relates to a gene trap construct containing a first reporter gene, which, after activation, can activate a second reporter gene, and the use of this gene trap construct for identification and/or isolation of genes, in particular transiently expressed genes. The invention relates further to a cell, preferably a mammal cell, containing the above-mentioned gene trap construct. The invention relates furthermore to the use of this mammal cell for identification and/or isolation of genes, in particular transient genes. In addition, the invention relates to a vector containing the above mentioned gene trap construction, as well as a kit for identifying and/or isolating genes, in particular transient genes, which contains at least the above-mentioned gene trap construct or the above-mentioned vector. Finally, the invention relates to a method for the identification and/or isolation of genes, in particular transient genes.
摘要:
The present invention provides a method of increasing the recombinant expression and solubility of influenza A virus M2 polypeptide comprising nucleic acids encoding a modified M2 protein of influenza A virus in which transmembrane and other hydrophobic domains have been deleted. The present invention also provides purified polypeptides encoded by the nucleic acids, which polypeptides are immunogenic and are less hydrophobic than full-length M2. Also provided are vaccines comprising variants of M2 expressed in prokaryotic hosts. Further provided are methods of preventing influenza A infection using vaccines comprised of variants of M2. Also provided are antibodies raised against the variants of M2, and use of such antibodies in diagnosis and treatment of influenza A infections.
摘要:
A preservation method for biological material having cell membranes includes microinjecting the cells with sugar; preparing the cells for storage; storing the biological material; and recovering the stored biological material from storage. Carbohydrate sugars such as trehalose, sucrose, fructose, dextran, and raffinose, may be used as bio-protective agents.
