Scientists Perfect Lab Technique to Study How Cells Power Themselves
Researchers have refined a method to observe mitochondrial DNA replication and gene expression in isolated cellular structures, offering a clearer window into how cells generate energy. The advance could accelerate drug development for mitochondrial diseases and help companies understand cellular dysfunction underlying metabolic disorders.
Originaltitel: Studying Mitochondrial Nucleic Acid Synthesis Utilizing Intact Isolated Mitochondria.
Mitochondria are eukaryotic organelles of endosymbiotic origin that contain their own genetic material, mitochondrial DNA (mtDNA), and dedicated systems for mtDNA maintenance and expression. MtDNA molecules encode a limited number of proteins that are nevertheless all essential subunits of the mitochondrial oxidative phosphorylation system. Here, we describe protocols to monitor DNA and RNA synthesis in intact, isolated mitochondria. These in organello synthesis protocols are valuable techniques for studying the mechanisms and regulation of mtDNA maintenance and expression.
