1. The role of the mitochondrial membrane system in apoptosis : the influence of oxidative stress on membranes and their interactions with apoptosis-regulating Bcl-2 proteins
Sammanfattning : Apoptosis is a crucial process in multicellular organisms in sculpting them, especially during embryogenesis. In addition, apoptosis is responsible for the clearance of harmful or damaged cells which can otherwise be detrimental to the organism. LÄS MER
2. Proton transfer across and along biological membranes
Sammanfattning : Proton-transfer reactions belong to the most prevalent reactions in the biosphere and make life on Earth possible, as they are central to energy conversion. In most known organisms, protons are translocated from one side of a membrane to the other, which generates an electrochemical gradient that drives ATP synthesis. LÄS MER
3. The plant respiratory chain: Redox responses and catalytic definition of alternative pathways
Sammanfattning : The respiratory chain of plants contains both proton-pumping enzymes that conserve energy and non-proton-pumping alternative enzymes that bypass the sites of energy conservation. In addition to the proton-pumping complex I, plant mitochondria contain alternative type II NAD(P)H dehydrogenases, which allow oxidation of NADH and NADPH from the matrix and the cytosol. LÄS MER
4. Bax and oxidized phospholipids - a deadly complex : Apoptotic protein-lipid assemblies studied by MAS NMR spectroscopy
Sammanfattning : Mitochondria are renowned for their vital role as cellular powerhouses because they provide ATP via cellular respiration. Additionally, these organelles also play an important role in other physiological processes, such as apoptosis. LÄS MER
5. Mitochondria in Alzheimer's Disease : The Presequence Protease and Mitochondria-Associated ER Membranes
Sammanfattning : Alzheimer’s disease (AD) is one of the most prevalent age-related neurodegenerative disorders and the accumulation of the amyloid-β peptide (Aβ) in the temporal lobe has been implicated in the pathology of AD. Synaptic transmission in neuronal cells is a highly energy dependent process, which relies on the presence and proper function of mitochondria. LÄS MER
