WebMar 3, 2024 · With cytosolic translation already established as a target for cancer therapy (Bhat et al., 2015, Faller et al., 2015, Pelletier et al., 2024), our work points to the possibility that this could be achieved through the cellular mechanisms in place to achieve mito-cytosolic translation balance. WebSynchronization of mitochondrial and cytoplasmic translation rates is critical for the maintenance of cellular fitness, with cancer cells being especially vulnerable to translational uncoupling. Although alterations of cytosolic protein synthesis are common in human cancer, compensating mechanisms in mitochondrial translation remain elusive. WebJan 18, 2024 · Cytosolic translation can be regulated by viral infection in animal cells (Sonenberg and Hinnebusch, 2009).
