Mitochondrial biogenesis, the process of increasing the size and number of mitochondria within cells, plays a crucial role in cancer metastasis. Metastasizing cells exhibit a unique metabolism that differs from the well-known Warburg effect observed in primary tumors. While primary tumors primarily rely on glycolysis for energy production, metastatic cells rely on oxidative phosphorylation and ATP generation for short-term energy needs. However, over longer time frames, mitochondrial biogenesis becomes a prominent feature in the success of metastasis. In a new study, researchers Gulimirerouzi Fnu and Georg F. Weber from the University of Cincinnati’s James L. Winkle College of Pharmacy investigate the connection between short-term oxidative metabolism and long-term mitochondrial biogenesis in cancer metastasis. They hypothesized that Osteopontin splice variants, specifically Osteopontin-c, stimulate an increase in mitochondrial size through the activation of specific signaling mechanisms. On December 1, 2023, their new research paper was published in Oncotarget, entitled, “Osteopontin induces mitochondrial biogenesis in deadherent cancer cells.” Full blog - https://www.oncotarget.org/2024/01/11/how-osteopontin-stimulates-mitochondrial-mass-and-cancer-metastasis/ Paper DOI - https://doi.org/10.18632/oncotarget.28540 Correspondence to - Georg F.
