This invention provides an isolated nucleic acid encoding a human MCH1 receptor, a purified human MCH1 receptor, vectors comprising isolated nucleic acid encoding a human MCH1 receptor, cells comprising such vectors, antibodies directed to a human MCH1 receptor, nucleic acid probes useful for detecting nucleic acid encoding human MCH1 receptors, antisense oligonucleotides complementary to unique sequences of nucleic acid encoding human MCH1 receptors, transgenic, nonhuman animals which express DNA encoding a normal or mutant human MCH1 receptor, methods of isolating a human MCH1 receptor, methods of treating an abnormality that is linked to the activity of a human MCH1 receptor, as well as methods of determining binding of compounds to mammalian MCH1 receptors. This invention provides a method of modifying the feeding behavior of a subject which comprises administering to the subject an amount of an MCH1 antagonist effective to decrease the body mass of the subject and/or decrease the consumption of food by the subject. This invention further provides a method of treating a subject suffering from depression and/or anxiety which comprises administering to the subject an amount of an MCH1 antagonist effective to treat the subject's depression and/or anxiety.
这项发明提供了编码人类MCH1受体的孤立核酸,纯化的人类MCH1受体,包括编码人类MCH1受体的孤立核酸的载体,包含这种载体的细胞,针对人类MCH1受体的抗体,用于检测编码人类MCH1受体的核酸探针,互补于编码人类MCH1受体独特序列的反义寡核苷酸,表达编码正常或突变人类MCH1受体的转基因非人类动物,孤立人类MCH1受体的分离方法,治疗与人类MCH1受体活性相关的异常的方法,以及确定化合物与哺乳动物MCH1受体结合的方法。这项发明提供了一种修改受试者摄食行为的方法,包括向受试者投与足以减少受试者体重和/或减少受试者食物摄入量的MCH1拮抗剂的量。这项发明还提供了一种治疗患有抑郁和/或焦虑的受试者的方法,包括向受试者投与足以治疗受试者抑郁和/或焦虑的MCH1拮抗剂的量。
