Abstract: The present invention provides a method for the prophylaxis or treatment of systemic lupus erythematosus and/or lupus nephritis in a patient in need thereof, which comprises administering an effective amount of [(1R)-1-({[(2, 5-dichlorobenzoyl)amino]acetyl}amino)-3-methylbutyl] boronic acid or a citric acid ester thereof, or a pharmaceutically acceptable salt thereof to the patient.

Abstract: The present invention provides a method for screening for a prophylactic or therapeutic drug for apoptosis or an inflammation-associated disease, diabetes and complications thereof or a chronic obstructive pulmonary disease (COPD), namely, a method for screening for a prophylactic or therapeutic drug for apoptosis or an inflammation-associated disease, diabetes and complications thereof or COPD, which includes (1) comparing the activities of a protein having an amino acid sequence the same as or substantially the same as the amino acid sequence shown by SEQ ID NO: 2 or a partial peptide thereof or a salt thereof, between in the presence of a test substance and in the absence of the test substance, or (2) comparing the expressions of a protein having an amino acid sequence the same as or substantially the same as the amino acid sequence shown by SEQ ID NO: 2, a partial peptide thereof and a salt thereof in the cells having the ability to produce the protein, the partial peptide thereof and the salt thereof, be

Abstract: The present application provides a human gene over-expressing animal, which is a non-human animal carrying a human hematopoietic prostaglandin D2 synthase gene in its somatic cell chromosome and expressing a large amount of human prostaglandin D2 synthase, wherein the animal is one obtained through ontogenesis of a totipotency cell of a non-human animal or offspring of the obtained animal, and the totipotency cell is introduced with said synthase gene. The present application also provides a method of using the transgenic animal for testing in vivo activity of a candidate for anti-allergy medicines, sleep-controlling substances and candidates for anti-obesity.
