Distinct Mitochondrial Remodeling During Mesoderm Differentiation in a Human-Based Stem Cell Model
Mostafavi, Sepideh; Balafkan, Novin; Pettersen, Ina Katrine Nitschke; Nido, Gonzalo Sanchez; Siller, Richard; Tzoulis, Charalampos; Sullivan, Gareth John; Bindoff, Laurence Albert (Journal article; Peer reviewed, 2021-10-14)Given the considerable interest in using stem cells for modeling and treating disease, it is essential to understand what regulates self-renewal and differentiation. Remodeling of mitochondria and metabolism, with the shift ... -
Nicotinamide Riboside and Metformin Ameliorate Mitophagy Defect in Induced Pluripotent Stem Cell-Derived Astrocytes With POLG Mutations
Chen, Anbin; Kristiansen, Cecilie Katrin; Hong, Yu; Kianian, Atefeh; Fang, Evandro Fei; Sullivan, Gareth John; Wang, Jian; Li, X.; Bindoff, Laurence Albert; Liang, Xiao (Journal article; Peer reviewed, 2021)Mitophagy specifically recognizes and removes damaged or superfluous mitochondria to maintain mitochondrial homeostasis and proper neuronal function. Defective mitophagy and the resulting accumulation of damaged mitochondria ... -
POLG mutations lead to abnormal mitochondrial remodeling during neural differentiation of human pluripotent stem cells via SIRT3/AMPK pathway inhibition
Chen, Anbin; Kristiansen, Cecilie Katrin; Høyland, Lena Elise; Ziegler, Mathias; Wang, Jian; Sullivan, Gareth John; Li, Xingang; Bindoff, Laurence Albert; Liang, Xiao (Journal article; Peer reviewed, 2022)We showed previously that POLG mutations cause major changes in mitochondrial function, including loss of mitochondrial respiratory chain (MRC) complex I, mitochondrial DNA (mtDNA) depletion and an abnormal NAD+/NADH ratio ...
