The present invention provides an antisense DNA to a disease-associated gene, drugs containing the antisense DNA, an antibody to a disease-associated gene product, diagnostics containing the antibody, a method of screening a compound capable of inhibiting the activities of the disease-associated gene product, compounds obtainable by the screening method, etc.
A compound which inhibits the activities of a protein having the same or substantially the same amino acid sequence as the amino acid sequence represented by SEQ ID NO: 1 or its salt and a neutralizing antibody capable of inhibiting the activities of the protein can be used, e.g., for the prevention/treatment of diseases such as bronchial asthma, chronic obstructive pulmonary disease, etc. The antisense DNA can inhibit the expression of a protein having the same or substantially the same amino acid sequence as the amino acid sequence represented by SEQ ID NO: 1, and can be used, e.g., for the prevention/treatment of diseases such as bronchial asthma, chronic obstructive pulmonary disease, etc.
本发明提供了一种疾病相关基因的反义 DNA、含有该反义 DNA 的药物、一种疾病相关基因产物的抗体、含有该抗体的诊断方法、一种能够抑制疾病相关基因产物活性的化合物的筛选方法、可通过该筛选方法获得的化合物等。
抑制与 SEQ ID NO: 1 所代表的氨基酸序列或其盐具有相同或基本相同的氨基酸序列的蛋白质的活性的化合物以及能够抑制该蛋白质活性的中和抗体可用于预防/治疗支气管哮喘、慢性阻塞性肺病等疾病。反义 DNA 可抑制具有与 SEQ ID NO: 1 所代表的氨基酸序列相同或基本相同的氨基酸序列的蛋白质的表达,可用于预防/治疗支气管哮喘、慢性阻塞性肺病等疾病。
