    • According to the disclosure hypoxia-mediated adipogenic inhibition involves the repression of PPARγ2 expression and its activity is a common mechanism for adipogenic inhibition by a variety of stimuli. The present disclosure relates to methods and compositions for regulating adipogenesis. The disclosure provides compositions comprising one or more DECI/Stra13 fragments of capable of inhibiting PPARγ2 promoter activity. These fragments, e.g. the basic helix loop helix domain or amino acids 1-141, have substantially the same PPARγ2 promoter repressing activity as the full length polypeptide. The present disclosure provides methods of inhibiting adipogenesis comprising contacting a cell with a fragment of DEC1/Stra13. The invention further relates to methods and compositions of inhibiting angiogenesis in a tumor comprising contacting a tumor or tumor cell with a DEC1/Stra13 agonist.
    • 根据该公开内容,缺氧介导的脂肪形成抑制涉及PPARgamma2表达的抑制,其活性是通过各种刺激造成脂肪形成抑制的常见机制。 本公开涉及用于调节脂肪形成的方法和组合物。 本公开提供了包含一种或多种能抑制PPARγ2启动子活性的DECI / Stra13片段的组合物。 这些片段,例如 碱性螺旋环螺旋结构域或氨基酸1-141具有与全长多肽基本上相同的PPARγ启动子抑制活性。 本公开提供了抑制脂肪形成的方法,包括使细胞与DEC1 / Stra13的片段接触。 本发明还涉及抑制肿瘤中血管生成的方法和组合物,包括使肿瘤或肿瘤细胞与DEC1 / Stra13激动剂接触。
