Assessment of Brown Adipocyte Thermogenic Function by High-throughput Respirometry

[Abstract]  Brown adipose tissue (BAT) has the unique ability to dramatically increase mitochondrial uncoupled fuel oxidation for thermogenesis in response to adrenergic stimulation. A key parameter in assessing brown adipocyte thermogenic capacity is mitochondrial uncoupling as determined by respiration. Measuring mitochondrial oxygen consumption rate (OCR) therefore provides valuable information to study the regulation and dysregulation of fuel metabolism and energy expenditure. Adding measurements of mitochondrial membrane potential allows for more in-depth interpretation of the respirometry data. ... [摘要]  棕色脂肪组织(BAT)具有显着增加线粒体解偶联燃料氧化以响应肾上腺素刺激的热生成的独特能力。评估棕色脂肪细胞产热能力的关键参数是通过呼吸确定的线粒体解偶联。因此,测量线粒体氧消耗率(OCR)为研究燃料代谢和能量消耗的调节和失调提供了有价值的信息。添加线粒体膜电位的测量允许更加深入地解释呼吸数据。在这里我们提供使用Seahorse XF分析仪测量贴壁完整和质膜透性棕色脂肪细胞呼吸的协议。在方案部分I中,去甲肾上腺素和游离脂肪酸的组合用于诱导解偶联呼吸。然后使用ATP合酶抑制剂寡霉素,化学去偶联剂FCCP和复合物III抑制剂抗霉素A分别测量偶联的,最大的和非线粒体的氧消耗。在方案第II部分中,质膜用重组perfringolysin O透化,胆固醇依赖性细胞溶解素寡聚化成在质膜中专门的孔。这允许代谢物可用性的实验性控制,而不从天然细胞环境中分离线粒体。

[Abstract]  Glioma Associated Stem Cells (GASCs) represent a population of non-tumorigenic multipotent stem cells hosted in the microenvironment of human gliomas. In vitro, these cells are able, through the release of exosomes, to increase the biological aggressiveness of glioma-initiating cells. The clinical importance of this finding is supported by the strong prognostic value associated with the GASCs surface immunophenotype thus suggesting that this patient-based approach can provide a groundbreaking method to predict prognosis and to exploit novel strategies that target the tumor stroma ... [摘要]  胶质瘤相关干细胞(GASC)代表在人类神经胶质瘤的微环境中存在的非致瘤性多能干细胞群体。 在体外,这些细胞能够通过外来体的释放增加胶质瘤起始细胞的生物攻击性。 该发现的临床重要性得到与GASCs表面免疫表型相关的强预后价值的支持,因此表明这种基于患者的方法可以提供开创性的方法来预测预后并开发靶向肿瘤基质的新策略(Bourkoula等人, et al。,2014)。
