Sci Rep:CPT1C通过调节自噬促进葡萄糖剥夺下的人类间充质干细胞的存活

2018-05-18 MedSci MedSci原创

人类间充质干细胞(hMSCs)广泛用于再生医学。在一些应用中,hMSCs必须在由血管生成引起的低营养条件下存活。改善hMSCs的存活或与组织工程具有高度相关性。肉碱棕榈酰转移酶1C(CPT1C)是在神经元和癌细胞中专一表达的假酶。在本研究中,研究人员发现CPT1C也在hMSCs中表达,并保护它们抵抗葡萄糖饥饿、糖酵解抑制和氧/葡萄糖剥夺。 结果显示,hMSCs中CPT1C过表达不增加脂肪酸氧

人类间充质干细胞(hMSCs)广泛用于再生医学。在一些应用中,hMSCs必须在由血管生成引起的低营养条件下存活。改善hMSCs的存活或与组织工程具有高度相关性。肉碱棕榈酰转移酶1C(CPT1C)是在神经元和癌细胞中专一表达的假酶。在本研究中,研究人员发现CPT1C也在hMSCs中表达,并保护它们抵抗葡萄糖饥饿、糖酵解抑制和氧/葡萄糖剥夺。

结果显示,hMSCs中CPT1C过表达不增加脂肪酸氧化能力,表明CPT1C在这些细胞中的作用不同于肿瘤细胞。葡萄糖缺乏期间观察到CPT1C过表达的hMSCs存活率增加是自噬增强的结果,导致更多的脂滴和细胞内ATP水平增加。事实上,抑制自噬或脂肪分解完全阻断了CPT1C的保护作用。

综上所述,该研究结果表明,在葡萄糖剥夺条件下CPT1C介导的自噬增强允许脂质的更大可用性以作为ATP生成的燃料底物,揭示了CPT1C在干细胞适应低营养环境中的新作用。
