    • A family of fatty acid transport proteins (FATPS) mediate transport of long chain fatty acids (LCFAs) across cell membranes into cells. These proteins exhibit different expression patterns among the organs of mammals. Nucleic acids encoding FATPs of this family, vectors comprising these nucleic acids, as well as the production of FATP proteins in host cells are described. Also described are methods to test FATPs for fatty acid transport function, and methods to identify inhibitors or enhancers of transport function. The altering of LCFA uptake by administering to the mammal an inhibitor or enhancer of FATP transport function of a FATP in the small intestine can decrease or increase calories available as fats, and can decrease or increase circulating fatty acids. The organ specificity of FATP distribution can be exploited in methods to direct drugs, diagnostic indicators and so forth to an organ such as the heart.
    • 一系列脂肪酸转运蛋白(FATPS)介导长链脂肪酸(LCFAs)在细胞膜中的转运到细胞中。 这些蛋白质在哺乳动物的器官中表现出不同的表达模式。 描述了编码该家族的FATP的核酸,包含这些核酸的载体以及宿主细胞中FATP蛋白的产生。 还描述了测试脂肪酸转运功能的FATP的方法,以及鉴定转运功能的抑制剂或增强子的方法。 通过向哺乳动物施用FATP在小肠中的FATP转运功能的抑制剂或增强剂,LCFA摄取的改变可以降低或增加作为脂肪获得的卡路里,并且可以减少或增加循环脂肪酸。 FATP分布的器官特异性可以用于将药物,诊断指标等引导到诸如心脏的器官的方法中。

    • The present invention relates to DNA encoding Acrp30, of vertebrate (e.g., mammalian) origin, and particularly of human and rodent origin. The present invention further relates to isolated, recombinantly produced or synthetic DNA which hybridizes to the nucleotide sequences described herein and RNA transcribed from the nucleotides sequence described herein. In addition, the invention relates to expression vectors comprising DNA encoding Acrp30, which is expressed when the vector is present in an appropriate host cell. The invention further relates to isolated, recombinantly produced or synthetic mammalian Acrp30 of vertebrate (e.g., mammalian) origin, and particularly of human and rodent origin. Also encompassed by the present invention is an inhibitor or enhancer of Acrp30. The present invention further relates to a method of identifying inhibitors or enhancers of Acrp30. Isolation of Acrp30 makes it possible to detect Acrp30 or adipocytes in a sample (e.g., test sample). In addition, the present invention relates to a method of regulating the energy balance (e.g., nutritional status) of a mammal by administering to the mammal an inhibitor or enhancer of the Acrp30.
    • 本发明涉及编码Acrp30的脊椎动物(例如哺乳动物)来源,特别是人和啮齿动物来源的DNA。 本发明还涉及与本文所述的核苷酸序列杂交的分离的,重组产生的或合成的DNA,以及从本文所述的核苷酸序列转录的RNA。 此外,本发明涉及包含编码Acrp30的DNA的表达载体,其在载体存在于合适的宿主细胞中时表达。 本发明还涉及脊椎动物(例如哺乳动物)来源,特别是人和啮齿动物来源的分离的重组产生或合成的哺乳动物Acrp30。 本发明还包括Acrp30的抑制剂或增强剂。 本发明还涉及鉴定Acrp30抑制剂或增强剂的方法。 Acrp30的分离使得可以检测样品中的Acrp30或脂肪细胞(例如测试样品)。 此外,本发明涉及通过向哺乳动物施用Acrp30的抑制剂或增强剂来调节哺乳动物的能量平衡(例如营养状态)的方法。
