  2. 11. Life without mitochondrial DNA : studies of transgenic mice

    Author : Jianming Wang; Karolinska Institutet; Karolinska Institutet; []
    Keywords : mitochondrial disease; mitochondrial DNA mtDNA ; mitochondrial transcripton factor A Tfam ; cre-loxP; conditional knockout; transgenic; mitochondrial cardiomyopathy; apoptosis;

    Abstract : Mitochondrial DNA (mtDNA) is a closed circular DNA genome that resides in the mitochondrial network. Mutations of mtDNA cause spontaneous and hereditary disorders known as mitochondrial diseases. Mitochondrial transcription factor A (Tfam) is a key factor for transcription of mtDNA in vitro.

  4. 12. Cell-penetrating peptide targeting mitochondria : Design, synthesis, characterization, and biological effects

    Author : Carmine Pasquale Cerrato; Ülo Langel; Lena Mäler; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; cell-penetrating peptide; mitochondrial targeting; ROS reduction; mitochondrial membrane potential; antioxidant activity; neurokemi med molekylär neurobiologi; Neurochemistry with Molecular Neurobiology;

    Abstract : More than twenty years after the discovery of the first cell-penetrating peptide (CPP), a large number of both naturally occurring as well as engineered CPPs have been discovered. Generally, CPPs are short polycationic sequences of less than 30 amino acids that are able to translocate different cargoes into cells. READ MORE

  5. 13. Mitochondrial dysfunction in ageing and degenerative disease

    Author : Anna Wredenberg; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : The cytoplasm of eukaryotic cells contains a dynamic network of double-membraned organelles, called mitochondria, which perform the process of oxidative phosphorylation (OXPHOS) that provides cellular energy in the form of ATP. The respiratory chain creates an electrochemical gradient across the inner mitochondrial membrane, which drives ATP synthesis by the ATP synthase. READ MORE

  6. 14. Pathogenic mechanisms affecting mitochondrial DNA replication and transcription

    Author : Meenakshi Singh; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; mtDNA; ribonucleotides; nucleoside analogues; POLRMT;

    Abstract : Mitochondria are cytoplasmic organelles fundamental to life and health. In mitochondria, energy from the food we eat is converted into adenosine triphosphate (ATP), which in turn is used as a source of chemical energy to drive a multitude of cellular reactions. READ MORE

  7. 15. Studies of nuclear encoded mitochondrial proteins in metabolism

    Author : Qian Zhao; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Mitochondrial function is vital for human health. Inherited genetic disease can cause mitochondrial DNA (mtDNA) deficiency, disorders with generally poor prognosis. The majority of the genesinvolved in keeping a normal mitochondrial function are nuclear encoded. READ MORE
