雷帕霉素复合物1(mTORC 1)的机制靶点是众所周知的响应于环境刺激和应激物的细胞生长和增殖的调节剂。迄今为止,大多数mTORC1研究都集中在其作为翻译调节的细胞质效应子的功能上。然而,最近的研究已经确定了额外的,核特异性的作用mTORC 1信号相关的核糖体DNA(rDNA)和核糖体蛋白(RP)基因的转录,有丝分裂细胞周期的控制,和表观遗传过程的调节。由于这一领域的研究仍处于起步阶段,本次审查的目的是突出这些重要的发现,并讨论核mTORC1信号失调的相关性,因为它涉及到健康和疾病。
Mechanistic target of rapamycin complex 1 (mTORC1) is a well-known regulator of cell growth and proliferation in response to environmental stimuli and stressors. To date, the majority of mTORC1 studies have focused on its function as a cytoplasmic effector of translation regulation. However, recent studies have identified additional, nuclear-specific roles for mTORC1 signaling related to transcription of the ribosomal DNA (rDNA) and ribosomal protein (RP) genes, mitotic cell cycle control, and the regulation of epigenetic processes. As this area of study is still in its infancy, the purpose of this review to highlight these significant findings and discuss the relevance of nuclear mTORC1 signaling dysregulation as it pertains to health and disease.
