WebJan 20, 2024 · A complex interplay between mRNA translation and cellular respiration has been recently unveiled, but its regulation in humans is poorly characterized in either health or disease. Cancer cells radically reshape both biosynthetic and bioenergetic pathways to sustain their aberrant growth rates. In this regard, we have shown that the molecular … WebAug 15, 2024 · Canonical retrograde signalling comprises information transmission from organelles to the nucleus and in particular controls gene expression for organellar proteins. The need to re-assess this paradigm was suggested by discrepancies between de novo protein synthesis and transcript abundance in response to excess light. Here we uncover …
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.
