Disclosed are messenger RNA molecules and related compositions incorporating a 4′-thio modification in the furanose ring of at least one nucleotide residue, and methods of using these mRNAs to produce an encoded therapeutic protein in vivo and to treat or prevent diseases or disorders. In certain embodiments, the 4′-thio modified mRNA provides for enhanced stability and/or reduced immunogenicity in in vivo therapies.
本发明涉及一种信使RNA分子及相关组合物,其中至少一个核苷酸残基的
呋喃糖环中包含4'-
硫修饰,并且使用这些mRNA在体内产生编码的治疗蛋白质并治疗或预防疾病或疾病的方法。在某些实施方式中,4'-
硫修饰的mRNA提供了增强的稳定性和/或减少了体内治疗中的免疫原性。
