Cellular studies have been undertaken on a nonamer peptide nucleic acid (PNA) sequence, which binds to mRNA encoding superoxide dismutase 1, and a series of peptide nucleic acids conjugated to synthetic lipophilic vitamin analogs including a recently prepared menadione (vitamin K) analog. Reduction of both mutant superoxide dismutase 1 inclusion formation and endoplasmic reticulum stress, two of the
已经对与编码超氧化物歧化酶1的mRNA结合的九聚体肽核酸(PNA)序列以及与包括最近制备的甲萘醌(维生素K)类似物的合成亲脂性维生素类似物缀合的一系列肽核酸进行了细胞研究。首次报道了通过制备的两种PNA寡聚体减少突变型超氧化物歧化酶1包涵体形成和内质网应激,这是肌萎缩性侧索硬化的两个关键细胞病理学特征。
