  2. 1. Mitochondrial Evolution : Turning Bugs into Features

    Author : Olof Karlberg; Siv Andersson; Michael Gray; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biology; Biologi; Biology; Biologi;

    Abstract : The bacterial origin of mitochondria from an ancient endosymbiosis is now widely accepted and the mitochondrial ancestor is generally believed to belong to the bacterial subdivision α-proteobacteria. The high fraction of mitochondrial proteins encoded in the nucleus has commonly been explained with a massive transfer of genes from the genome of the ancestral mitochondrion. READ MORE

  4. 2. Genotypic and phenotypic spectrum of mitochondrial diseases with focus on early onset mitochondrial encephalopathies

    Author : Kalliopi Sofou; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Mitochondrial diseases; mitochondrial encephalopathy; Alpers syndrome; Leigh syndrome; neuroimaging; whole exome sequencing;

    Abstract : Early-onset mitochondrial encephalopathies comprise a challenging group of neurodegenerative disorders. This is due to their progressive nature, often leading to major disability and premature death, as well as their diagnostic complexity and lack of customized treatments. READ MORE

  5. 3. Characterization of land plant-specific proteins required for mitochondrial translation initiation

    Author : Huy Cuong Tran; Molekylär cellbiologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Mitochondrial unfolded protein response; Arabidopsis mitochondrial isolation; mitoribosome; mitochondrial translation initiation; mitoribosome small subunit; mTRAN; mTRAN-mRNA interaction;

    Abstract : Plant mitochondria produce the majority of adenosine triphosphate (ATP) – the cellular energy currency for metabolic reactions needed for plant growth, development, and maintenance. Despite a relatively thorough understanding of basic mitochondrial functions, many mitochondrial proteins and processes remain poorly understood. READ MORE

  6. 4. Identification of abnormally expressed genes in skeletal muscle contributing to insulin resistance and type 2 diabetes

    Author : Xudong Huang; Malmö Institutionen för kliniska vetenskaper; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Endocrinology; secreting systems; diabetology; Endokrinologi; gene expression; high-fat intake; RT-PCR; mitochondrial genes; cathepsin L; Shc; IRS-2; IRS-1; GS; cDNA differential display; Insulin resistance; type 2 diabetes; sekretion; diabetologi;

    Abstract : The metabolic defects of insulin resistance and type 2 diabetes can result from changes in gene expression and protein functions due to genetic and environmental influences. The aim of this study was to identify abnormally expressed genes associated with insulin resistance or type 2 diabetes, and further to test whether possible defects are inherited or acquired.

  7. 5. Transcriptional regulation of human nuclear encoded mitochondrial genes

    Author : Ahmed Zaid; Richard Scarpulla; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; biokemi; Biochemistry;

    Abstract : Biogenesis of mammalian mitochondria requires the participation of both nuclear and mitochondrial genes. This thesis presents studies that characterize the common features of several nuclear encoded mitochondrial promoter genes and proposes the identity of factors regulating the transcription and responsible for coordinated, constitutive expression of diverse mammalian oxidative phosphorylation (OXPHOS) genes.
