维生素 D3 缺乏现象十分普遍,这可能会增加许多疾病的风险,包括癌症、心血管疾病和自身免疫性疾病。活性代谢物 1,25-二羟基维生素 D (1,25D) 的基因组活性介导维生素 D3 的大部分作用,并且 1,25D 的许多基因靶标已得到表征。随着非编码 RNA 重要性的凸显,维生素 D3 通过 1,25D 调节 microRNA (miRNA) 的能力已在多种癌细胞系、患者组织和血清中得到证实。在维生素 D3 干预患者试验中,观察到治疗组之间和/或基线与随访之间 miRNA 存在显着差异。在群体研究的患者血清中,特定的 miRNA 差异与 25D 的血清水平相关。迄今为止的研究结果表明,患者饮食中的维生素 D3 和体外的 1,25D 不仅可以调节特定的 miRNA,而且还可能整体上调 miRNA 水平。本文是题为“维生素 D 研讨会”的特刊的一部分。
Vitamin D3 deficiency is rampant which may contribute to increased risk of many diseases including cancer, cardiovascular disease and autoimmune disorders. Genomic activity of the active metabolite 1,25-dihydroxyvitamin D (1,25D) mediates most vitamin D3's actions and many gene targets of 1,25D have been characterized. As the importance of non-coding RNAs has emerged, the ability of vitamin D3 via 1,25D to regulate microRNAs (miRNAs) has been demonstrated in several cancer cell lines, patient tissue and sera. In vitamin D3 intervention patient trials, significant differences in miRNAs are observed between treatment groups and/or between baseline and followup. In patient sera from population studies, specific miRNA differences associate with serum levels of 25D. The findings thus far indicate that dietary vitamin D3 in patients and 1,25D in vitro not only regulate specific miRNA(s), but may also globally upregulate miRNA levels. This article is part of a Special Issue entitled ‘Vitamin D Workshop’.
