Endoplasmic reticulum stress has been found to be associated with obesity. Therefore, agents that reduce or prevent ER stress may be used to treat diseases associated with obesity including peripheral insulin resistance, hypergylcemia, and type 2 diabetes. Two compounds which have been shown to reduce ER stress and to reduce blood glucose levels include 4-phenyl butyric acid (PBA), tauroursodeoxycholic acid (TUDCA), and trimethylamine N-oxide (TMAO). Other compounds useful in reducing ER stress are chemical chaperones such as trimethylamine N-oxide and glycerol. The present invention provides methods of treating a subject suffering from obesity, hyperglycemia, type 2 diabetes, or insulin resistance using ER stress reducers such as PBA, TUDCA, and TMAO. Methods of screening for ER stress reducers by identifying agents that reduce levels of ER stress markers in ER stressed cells are also provided. These agents may find use in methods and pharmaceutical compositions for treating obesity-associated diseases.
研究发现,内质网应激与肥胖有关。因此,减少或预防内质网应激的药物可用于治疗与肥胖有关的疾病,包括外周胰岛素抵抗、高血糖和 2 型糖尿病。有两种化合物已被证明可以减少ER应激和降低血糖水平,其中包括4-苯基丁酸(PBA)、牛磺酸去氧胆酸(TUDCA)和三甲胺N-氧化物(TMAO)。其他有助于降低 ER 应激的化合物还有化学伴侣素,如三甲胺 N-氧化物和甘油。本发明提供了使用ER应激还原剂如PBA、TUDCA和TMAO治疗肥胖、高血糖、2型糖尿病或胰岛素抵抗的方法。此外,还提供了通过识别能降低 ER 应激细胞中 ER 应激标记物水平的制剂来筛选 ER 应激抑制剂的方法。这些制剂可用于治疗肥胖相关疾病的方法和药物组合物中。
