Targeting delivery nucleic acid into mammalian mitochondria / 中国药理学通报

ABSTRACT

Mitochondrial DNA (mtDNA)genome mutations and defects are the essential mechanism of a various of mitochondrial dysfunction associated with diseases. The studies of targeting de-livery nucleic acid into mammalian mitochondria can thoroughly correct mtDNA mutation, rescue mtDNA impairment and then reverse the progress of diseases. There’s obvious differences be-tween nucleic acid import pathway of mammalian mitochondria and gene transfection of nuclei. In this paper, the effective strat-egies of delivering DNA and RNA(tRNA,rRNA,mRNA and an-tisense RNA)into mitochondria have been reviewed, as well as the challenges and development.
