Alterations in mitochondrial function and energy metabolism-related properties in thyroid cancer stem cells

This study aimed at testing the abnormalities in mitochondrial function and energy/metabolism-related phenotypes in thyroid cancer stem cells (TCSCs). TCSCs were isolated and identified from MDA-T32 thyroid carcinoma cell line. The mitochondrial mass and mitochondrial arrangement, amount of mitochondrial DNA (mtDNA), mitochondrial membrane potential (MMP), oxygen/glucose consumption, and intracellular concentrations of reactive oxygen species (ROS) and ATP levels were examined. Perinuclear mitochondrial distribution, low amount of mtDNA and oxygen/glucose consumption, high MMP, and low intracellular ROS and ATP concentrations were observed in TCSCs. Alterations in mitochondrial function and cellular energy metabolism may be used as novel indicators of thyroid cancer.PMID:34826218 | DOI:10.18388/abp.2020_5370
