2725 results about "Phosphorylation" patented technology

In chemistry, phosphorylation of a molecule is the attachment of a phosphoryl group. Together with its counterpart, dephosphorylation, it is critical for many cellular processes in biology. Phosphorylation is especially important for protein function; for example, this modification activates (or deactivates) almost half of the enzymes present in yeast, thereby regulating their function. Many proteins (between 1/3 to 2/3 of the proteome in eukaryotes) are phosphorylated temporarily, as are many sugars, lipids, and other biologically-relevant molecules.

Method for treating cancer using p38/JTV-1 and method for screening pharmaceutical composition for treating cancer

The present invention relates to a method for treating cancer using p38 / JTV-1 and a method for screening pharmaceutical composition for treating cancer. More particularly, this invention relates to the method for treating cancer, which comprises administering the effective amount of p38 / JTV-1 protein or a nucleic acid encoding for said protein to the patient and the method for screening a pharmaceutical composition for treating cancer characterized by selecting a substance having an effect on the increase of the activity of the p38 / JTV-1 protein and the intracellular level thereof.The method according to the invention can be effectively used to treat cancer through the mechanism of suppressing the proliferation of cancer cells by binding to FBP (FUSE-binding protein) and thereby promoting the ubiquitination of FBP to downregulate c-myc gene, which is a proto-oncogene, and the mechanism of promoting the apoptosis of cells by binding to PDK-1 (phosphoinositide-dependent protein) and thereby inhibiting the phosphorylation of AKT (serine / threonine kinase). Also, p38 / JTV-1 can be used as a target for screening of new anticancer agents, by virtue of such regulation mechanisms of p38 / JTV-1.

Methods for diagnosis prognosis and methods of treatment

This invention is directed to methods and compositions for diagnosis, prognosis and for determining methods of treatment. The physiological status of cells present in a sample (e.g. clinical sample) can be used in diagnosis or prognosis of a condition (e.g. Chronic Lymphocytic Leukemia), in patient selection for therapy, to monitor treatment and to modify or optimize therapeutic regimens. The physiological status of a cell can be determined by comparing the intracellular status of one or more activation elements (e.g. the phosphorylation status of a signaling molecule) in a cell (e.g. a cancer cell) to that of another cell (e.g. a normal cell). The physiological status of a cell can be further classified by adding one or more modulators (e.g. an inhibitor or activator) to the cell in question. In some embodiments, the invention is directed to methods of determining a phenotypic profile of a population of cells.

Neuronal pain pathway

The present invention relates to the discovery of a novel molecular pathway involved in long-term hyperexcitability of sensory neurons, which, in higher animals, is associated with persistent pain. It is based on the discovery that, following injury to an axon of a neuron, an increase in nitric oxide synthase activity results in increased nitric oxide production, which, in turn, activates guanylyl cyclase, thereby increasing levels of cGMP. Increased cGMP results in activation of protein kinase G (“PKG”), which then is retrogradely transported along the axon to the neuron cell body, where it phosphorylates MAPKerk.

Whole blood preparation for cytometric analysis of cell signaling pathways

This invention is directed to a method for preparation of a biological sample for measurement of protein epitopes that allows for the preservation of intracellular protein epitopes and detection of signal transduction pathways based on the ability to capture transient activation states of the epitopes. The method provided by the invention allows for the rapid fixation of biological samples containing red blood cells, to ensure that epitopes of signal transduction molecules and other intracellular protein epitopes are preserved in the active state. The method of the invention further allows for lysis of red blood cells, thereby making it a useful method for cytometric analysis of biological samples, including, for example, whole blood, bone marrow aspirates, peritoneal fluids, and other red blood cell containing samples. The invention also provides a method to recover or “unmask” epitopes on intracellular antigens that have been made inaccessible by the cross linking fixative necessary to fix the sample. Significantly, the methods of the invention allow preservation and analysis of phospho-epitope levels in biological samples taken directly from patients to determine disease-specific characteristics.
