乙二醛酶系统是抗糖基化酶防御的重要组成部分,可以防止甲基乙二醛对蛋白质和DNA的糖基化,特别是在数量上和功能上都很重要。编码Glo1 (glyoxalase I)和Glo2 (glyoxalase II)的基因表达可能被诱导或抑制,Glo1和Glo2蛋白的蛋白水解率可能在健康和疾病中发生变化。在mRNA和蛋白水平上定量评估乙二醛酶基因表达已成为表征乙二醛酶系统的关键部分。对于mRNA,常用的技术是实时RT(逆转录)-PCR和通过Nanostring™方法直接定量mRNA拷贝数。对于乙二醛酶蛋白的定量,有常用的Western blotting,也有免疫测定,在蛋白质组研究中,有定量蛋白质组学和蛋白质组动力学。我们提供了下面常见方法的协议,并简要回顾了它们的应用。
The glyoxalase system is an important component of the enzymatic defence against glycation, preventing particularly quantitatively and functionally important glycation of protein and DNA by methylglyoxal. Expression of genes encoding Glo1 (glyoxalase I) and Glo2 (glyoxalase II) may be induced or suppressed, and rates of proteolysis of Glo1 and Glo2 proteins may change in health and disease. Quantitative assessment of glyoxalase gene expression at the mRNA and protein levels has become a key part of glyoxalase system characterization. For mRNA, there is the common technique of real-time RT (reverse transcription)–PCR and direct quantification of mRNA copy number by the Nanostring™ method. For glyoxalase protein quantification, there is the commonly used Western blotting, and also immunoassay and, in proteome-wide studies, quantitative proteomics and proteome dynamics. We provide protocols for the common methods below and briefly review their application.
