20110151471RIBOSWITCHES, METHODS FOR THEIR USE, AND COMPOSITIONS FOR USE WITH RIBOSWITCHES - It has been discovered that certain natural mRNAs serve as metabolite-sensitive genetic switches wherein the RNA directly binds a small organic molecule. This binding process changes the conformation of the mRNA, which causes a change in gene expression by a variety of different mechanisms. Modified versions of these natural “riboswitches” (created by using various nucleic acid engineering strategies) can be employed as designer genetic switches that are controlled by specific effector compounds. Such effector compounds that activate a riboswitch are referred to herein as trigger molecules. The natural switches are targets for antibiotics and other small molecule therapies. In addition, the architecture of riboswitches allows actual pieces of the natural switches to be used to construct new non-immunogenic genetic control elements, for example the aptamer (molecular recognition) domain can be swapped with other non-natural aptamers (or otherwise modified) such that the new recognition domain causes genetic modulation with user-defined effector compounds. The changed switches become part of a therapy regimen—turning on, or off, or regulating protein synthesis. Newly constructed genetic regulation networks can be applied in such areas as living biosensors, metabolic engineering of organisms, and in advanced forms of gene therapy treatments.06-23-2011

20120329066FARNESYLTRANSFERASE INHIBITORS FOR TREATMENT OF LAMINOPATHIES, CELLULAR AGING AND ATHEROSCLEROSIS - Although it can be farnesylated, mutant lamin A expressed in Hutchinson Gilford Progeria Syndrome cannot be defarnesylated; the characteristic mutation causes deletion of a cleavage site necessary for binding the protease ZMPSTE24 and effecting defarnesylation. The result is an aberrant farnesylated protein (“progerin”) that alters normal lamin A function as a dominant negative, and assumes its own aberrant function through its association with the nuclear membrane. Retention of farnesylation, and potentially other abnormal properties of progerin and other abnormal lamin gene protein products, produces disease. Farnesyltransferase inhibitors (FTIs) will inhibit formation of progerin, cause a decrease in lamin A protein, and/or an increase prelamin A protein. Decreasing the amount of aberrant protein improves cellular effects caused by and progerin expression. Similarly, treatment with FTIs should improve disease status in progeria and other laminopathies. In addition, elements of atherosclerosis and aging in non-laminopathy individuals will improve after treatment with FTIs.12-27-2012

20130171655NOVEL BIOLOGICAL DETECTION METHOD FOR DIOXINS IN SERUM, AND A DIAGNOSTIC USE THEREFOR IN METABOLIC SYNDROME AND RELATED CONDITIONS - The present invention relates to a novel biological detection method for dioxins in serum and a diagnostic use thereof in metabolic syndrome and related conditions. More particularly, according to the present invention, a significant correlation between dioxin content in serum and physical variables has been confirmed by measuring luciferase activity through the use of serum as a whole and cells transformed with a recombinant vector comprising a gene construct in which a dioxin responsive element, a promoter and a reporter gene are operably linked. And there is an improvement in this method of the present invention over the conventional methods which require a preprocessing step in order to purify dioxins from serum, by which plural samples can be analyzed easily and accurately even with a very small amount of each because of the use of serum as a whole. Therefore, the detection system of the present invention which involves total serum processing in a genetically transformed cell line comprising a recombinant reporter gene whose expression is modified by dioxin compounds can be effectively used for the biological detection of dioxins in serum. This method can also be used to research the correlation between specific POPs and patient's disease factors by accurate detection of POPs such as dioxins in the serum, and further this method can be effectively used to predict the occurrence of disease and to determine treatability.07-04-2013
20130177919PROTEIN PRODUCTION - The invention concerns the field of protein production and cell culture technology. CERT is identified as a novel in vivo PKD substrate. Phosphorylation on serine 132 by PKD decreases the affinity of CERT towards its lipid target phosphatidylinositol 4-phosphate at Golgi membranes and reduces ceramide transfer activity, identifying PKD as a regulator of lipid homeostasis. The present invention shows that CERT in turn is critical for PKD activation and PKD dependent protein cargo transport to the plasma membrane. The interdependence of PKD and CERT is thus a key to the maintenance of Golgi membrane integrity and secretory transport.07-11-2013
