在血红蛋白病的治疗中,修正改变的血红蛋白和/或过量产生的珠蛋白是治疗策略的重要部分,并且选择性抑制珠蛋白产生可能在临床上有益。因此,需要开发基于药物的方法来选择性抑制珠蛋白积累。在这项研究中,我们利用肽核酸 (PNA) 来改变珠蛋白基因表达。本研究的主要结论是,针对成年鼠 β-珠蛋白 mRNA 设计的 PNA 能够高效且选择性地抑制鼠红白血病 (MEL) 细胞的血红蛋白积累和红系分化。没有观察到对细胞增殖的重大影响。我们的研究支持这样的概念:PNA 可用于靶向 mRNA,这些 mRNA 与珠蛋白 mRNA 类似,在分化的红系细胞中以非常高的水平表达。我们的数据表明,PNA 抑制参与血红蛋白病病理生理学的球蛋白的过量产生。
In the treatment of hemoglobinopathies, amending altered hemoglobins and/or globins produced in excess is an important part of therapeutic strategies and the selective inhibition of globin production may be clinically beneficial. Therefore the development of drug-based methods for the selective inhibition of globin accumulation is required. In this study, we employed peptide nucleic acids (PNAs) to alter globin gene expression. The main conclusion of the present study was that PNAs designed to target adult murine β-globin mRNA inhibit hemoglobin accumulation and erythroid differentiation of murine erythroleukemia (MEL) cells with high efficiency and fair selectivity. No major effects were observed on cell proliferation. Our study supports the concept that PNAs may be used to target mRNAs that, similar to globin mRNAs, are expressed at very high levels in differentiating erythroid cells. Our data suggest that PNAs inhibit the excess production of globins involved in the pathophysiology of hemoglobinopathies.
