| 背景 | Nuclear retinoic acid (RA) receptors (RARs) consist of three subtypes encoded by separate genes: α (NR1B1), β (NR1B2), and γ (NR1B3). For each subtype, there are at least two isoforms, which are generated by differential promoter usage and alternative splicing and differ only in their N-terminal regions. Retinoids, which are metabolites of vitamin A, serve as ligands for RARs (1). RARs function as ligand-dependent transcriptional regulators and are found to be heterodimerized with retinoid X receptors (RXRs). These transcriptionally active dimers regulate the expression of genes involved in cellular differentiation, proliferation, and apoptosis (2,3). Consequently, RARs play critical roles in a variety of biological processes, including development, reproduction, immunity, and organogenesis (4-6). RAR mutations, fusion proteins, altered expression levels, or aberrant post-translational modifications result in multiple diseases due to altered RAR function and disruption of homeostasis. In contrast to the ubiquitously expressed RARα subtype, RARγ displays a complex tissue-specific expression pattern (7). The hematopoietic system expresses significant levels of RARγ, and a recent study identified a role for RARγ in hematopoietic stem cell maintenance (8). RARγ is the predominant subtype in human and mouse epidermis, representing 90% of the RARs in this tissue (9-11). Given the high level of RARγ expression in the skin, it has been suggested that this nuclear receptor participates in a transcriptional program that governs maintenance and differentiation of normal epidermis and skin appendages. The transcriptional activity of RARγ is under stringent control, in part, through retinoic acid-induced phosphorylation and proteasomal degradation (12).维甲酸（RA）核受体（RARs）包括三个亚型，这三个亚型分别由α (NR1B1), β (NR1B2), 和γ (NR1B3)编码.每种亚型至少有两种形式，通过差动启动子使用和选择性剪接产生，不同之处仅在于它们的N-端区域。维甲酸是维生素A的代谢产物，作为维甲酸受体的配体（1）。维甲酸受体以配体依赖的转录调节起作用，发现其与维甲酸X受体（RXRs）形成异源二聚体。这些转录活性二聚体调节参与细胞分化、增殖、细胞凋亡的基因表达（2,3）。因此，维甲酸受体在各种生物过程，包括发育、生殖、免疫、器官生成中发挥关键作用（4-6）。由于RAR功能改变和动态平衡破坏、RAR突变、融合蛋白、表达水平的改变或翻译后修饰异常会导致多种疾病。与广泛表达的RARα亚型相反，RARγ显示一个复杂的组织特异性表达模式（7）。造血系统RARγ表现显着水平，最近的一项研究确定了RARγ在造血干细胞维护中的作用（8）。RARγ是人类和小鼠表皮的主要亚型，占这种组织中RARs的90％（9-11）。由于RARγ在皮肤中的表达水平高，曾有人建议，该核受体参与转录程序，管理正常表皮和皮肤附属组织的维护和分化。RARγ转录活性的严格控制，某种程度上通过维甲酸诱导的磷酸化和蛋白酶体降解（12）。 |
