MOTS-c (human) acetate 是一种线粒体来源的多肽,调节 AMPK/PGC-1α 通路增强胰岛素敏感性。MOTS-c (human) acetate 抑制叶酸循环和嘌呤从头合成,升高 AICAR 水平以激活 AMPK,进而调控 Nrf2/Keap1 抗氧化通路及抑制NF-κB炎症通路,同时促进线粒体生物发生和能量代谢。MOTS-c (human) 具有改善糖脂代谢、抗氧化应激、抗炎及神经保护的作用,可用于 2 型糖尿病、创伤性脑损伤、炎症性疾病及衰老相关代谢紊乱等研究。
序列:H‑Met‑Arg‑Trp‑Gln‑Glu‑Met‑Gly‑Tyr‑Ile‑Phe‑Tyr‑Pro‑Arg‑Lys‑Leu‑Arg‑OH
IC50 与作用靶点: AMPK、GLUT4、AICAR
体外实验: MOTS‑c 在 5‑Me‑THF(5‑甲基四氢叶酸)环节抑制叶酸循环,造成 AICAR(5‑氨基咪唑‑4‑甲酰胺核糖核苷酸)蓄积。MOTS‑c 同时能够提升细胞内 NAD⁺水平,NAD⁺同样属于核苷酸前体。
体内实验: 对小鼠注射 MOTS‑c,可激活骨骼肌 AMPK,并提高其下游葡萄糖转运蛋白 GLUT4 的表达水平。MOTS‑c 还可作为潜在的线粒体信号分子,介导运动诱导的线粒体兴奋效应(mitohormesis)。
生物活性: MOTS‑c(人源)醋酸盐为线粒体来源肽。MOTS‑c(人源)醋酸盐促使 AMP 类似物 AICAR 蓄积,增强 AMPK 激活,提升其下游 GLUT4 的表达;MOTS‑c(人源)醋酸盐可诱导葡萄糖摄取并改善。
MOTS-c (human) acetate is a mitochondrial-derived peptide that modulates the AMPK/PGC‑1α pathway to enhance insulin sensitivity. MOTS-c (human) acetate inhibits the folate cycle and de novo purine synthesis, elevates the level of AICAR to activate AMPK, thereby regulating the Nrf2/Keap1 antioxidant pathway and suppressing the NF‑κB inflammatory pathway. Meanwhile, it promotes mitochondrial biogenesis and energy metabolism. MOTS-c (human) exhibits effects of improving glucose and lipid metabolism, resisting oxidative stress, anti-inflammation and neuroprotection. It can be used in researches on type 2 diabetes, traumatic brain injury, inflammatory diseases and aging-related metabolic disorders.
Sequence: H‑Met‑Arg‑Trp‑Gln‑Glu‑Met‑Gly‑Tyr‑Ile‑Phe‑Tyr‑Pro‑Arg‑Lys‑Leu‑Arg‑OH
IC50& Target:AMPK、GLUT4、AICAR
In Vitro: MOTS‑c inhibits the folate cycle at the level of 5‑Me‑THF (5‑methyltetrahydrofolate), resulting in the accumulation of AICAR (5‑aminoimidazole‑4‑carboxamide ribonucleotide). MOTS‑c also increases cellular NAD⁺ levels, and NAD⁺ is also a nucleotide precursor.
In Vivo: Administration of MOTS‑c to mice activates AMPK in skeletal muscle and upregulates the expression level of its downstream glucose transporter GLUT4. As a potential mitochondrial signaling molecule, MOTS‑c can also mediate exercise-induced mitohormesis.
Biological Activity: MOTS‑c (human) acetate is a mitochondrial‑derived peptide. MOTS‑c (human) acetate induces the accumulation of the AMP analog AICAR, enhances AMPK activation and upregulates the expression of its downstream GLUT4. MOTS‑c (human) acetate can induce glucose uptake and improve.
