Abstract: Novel organisms, including DNA construct host cell combinations, are disclosed. The organisms comprise a transcription unit (e.g. operon) comprising DNA sequences encoding for enzymes which promote the supply of single carbon units for the conversion of dUMP to dTMP. Examples include: dihydrofolate reductase genes e.g. T4 frd; Serine Hydroxymethyltransferase genes e.g. glyA; 3-phosphoglycerate dehydrogenase genes e.g. serA; and THF synthase genes e.g. ADE3. The organisms are used in a biological method of producing thymidine with significantly reduced levels of uridine.

Abstract: The present invention is based, in part, on our discovery that EGF can be engineered to generate mutants that bind to the EGF receptor (EGFR) of a cell and that have a desirable effect on the activity of the cell. For example, the mutants can agonize the receptor (i.e., increase a biological activity of the receptor), or antagonize the receptor (i.e., decrease or inhibit a biological activity of the receptor). In turn, the rate at which the cell proliferates, for example, can be changed. Moreover, some of these mutants bind EGFR with a higher affinity than wild-type EGF exhibits. The affinity may increase by about, for example, 2-, 5-, 10-, 15-, 20-, 25-, 30-, 50-, or 100-fold relative to wild-type EGF.
Abstract: The invention relates to the cDNA and deduced amino acid sequence of the Coactivator Associated arginine (R) Methyltransferase protein, CARM1. A method is described for the use CARM1 to regulate gene expression in vivo. CARM1 has also been used to methylate arginine residues of histones, synthetic peptides, and other proteins. A method to use CARM1 to screen for drugs that inhibit its methyltransferase activity is also described, as is a method to screen for drugs that modulate CARM1's interactions with other proteins.

Abstract: The invention provides an isolated, novel steroid 5?-reductase enzyme termed SRD5AIII. The protein has an estimated molecular weight of 37 kDa and is capable of converting testosterone to dihydrotestosterone at a pH of about 7.0. Also provided is a method for identifying inhibitors of SRD5AIII by contacting SRD5AIII with a test compound and measuring the activity of the enzyme. A reduced activity relative to a control indicates that the test compound is an inhibitor of SRD5AIII. A method is also provided for detecting androgen stimulated prostate cancer or recurrent prostate cancer in an individual. The method comprises obtaining a prostate biopsy from an individual and determining the level of expression of SRD5AIII gene or protein relative to a normal control. An increased expression of SRD5AIII relative to the control is indicative of androgen stimulated prostate cancer or recurrent prostate cancer.

Abstract: The present invention relates to mutant microorganisms having improved productivity of branched-chain amino acids, and a method for producing branched-chain amino acids using the mutant microorganisms. More specifically, relates to mutant microorganisms having improved productivity of L-valine, which are produced by attenuating or deleting a gene encoding an enzyme involved in L-isoleucine biosynthesis, a gene encoding an enzyme involved in L-leucine, and a gene encoding an enzyme involved in D-pantothenic acid biosynthesis, and mutating a gene encoding an enzyme involved in L-valine biosynthesis, such that the expression thereof is increased, as well as a method for producing L-valine using the mutant microorganisms. The inventive mutant microorganisms produced by site-specific mutagenesis and metabolic pathway engineering can produce branched-chain amino acids, particularly L-valine, with high efficiency, and thus will be useful as industrial microorganisms for producing L-valine.

Abstract: The objective of the present invention is to provide a method and instrument for measuring glucose concentration in blood using infrared spectroscopy. Glucose concentration in blood is measured based on an integrated value obtained by measuring an absorption spectrum that includes the wavenumber range of 1020-1040 cm?1, and by integrating the intensity of absorption of the wavenumber range of 1020-1040 cm?1 within the absorption spectrum. Alternatively, a glucose concentration in blood is measured based on an integrated value through measuring an absorption spectrum including the wavenumber range of 1010-1050 cm31 1; obtaining a second-derivative spectrum by calculating a second derivative of the absorption spectrum that includes the wavenumber range of 1010-1050 cm?1 in the absorption spectrum; determining an integration range based on the second derivative spectrum; and then obtaining the integrated value by integrating the intensity of absorption based on this determined integration range.

Abstract: Provided is a biomarker that enables easy and rapid detection of oxidative stress on a living organism and enables prevention of tissue damage or cell necrosis by drug administration, and which is a powerful marker for the study of toxicity and pharmacokinetics of various agents. Oxidative stress is determined by measuring blood concentration of ophthalmic acid, which is a substance that varies in blood depending on the variation of reduced glutathione (GSH) concentration in a biological sample with the use of an analyzer such as a capillary electrophoresis-mass spectrometer. Further, an anti-oxidative stress agent is screened by administering an anti-oxidative stress candidate agent to a non-human animal under oxidative stress conditions, measuring blood concentration of ophthalmic acid, and evaluating the degree of decrease in the ophthalmic acid concentration.
