概括
甲状腺激素 (T3) 信号传递对脂肪代谢和治疗与代谢功能障碍相关的脂肪性肝病 (MASLD) 至关重要. 选择性甲状腺激素受体β (THRβ) 激动剂,如resmetirom,为纤维化MASLD提供了一个有前途的治疗方法.
科学领域:
- 肝病学和内分泌学.
- 肝病的分子机制 肝病的分子机制
- 甲状腺激素信号通道的信号通道.
背景情况:
- 与代谢功能障碍相关的脂肪性肝病 (MASLD) 与低甲状腺激素 (T3) 水平有关,甲状腺功能低下会增加MASLD风险.
- 美国食品和药物管理局 (FDA) 批准的非酒精性脂肪肝炎 (NASH) 治疗纤维化症的药物Resmetirom在与生活方式改变相结合时改善肝脏结果.
- 了解MASLD中的T3信号是开发向治疗的关键.
研究的目的:

Glucagon-like Receptor Agonists
295
Incretins include glucagon-like peptide-1 (GLP-1) and glucose-dependent insulinotropic polypeptide (GIP), which stimulate insulin secretion post-meals. In type 2 diabetes, GIP's efficacy is reduced, making GLP-1 a viable drug target. GIP originates from preproGIP.
GLP-1, when administered in high doses intravenously, triggers insulin secretion, inhibits glucagon release, slows gastric emptying, reduces food intake, and restores normal insulin secretion. However, its rapid inactivation by...

Oral Hypoglycemic Agents: Biguanides and Glitazones
165
Biguanides, particularly metformin (Glucophage), are insulin sensitizers that enhance glucose uptake, thereby reducing insulin resistance. Unlike sulfonylureas, metformin doesn't prompt insulin secretion, which helps to curb hypoglycemia risk. Metformin is beneficial in treating conditions like polycystic ovary syndrome due to its insulin-resistance reduction capability. The drug's primary action involves curtailing hepatic gluconeogenesis, a significant contributor to high blood...
