Chemical modifications extend beyond structural roles by shaping ribosome functionality and cellular protein profiles. The review discusses how rRNA modifications regulate rRNA activity as well as wider cellular physiological processes, including shifts in translational output that can promote oncogenesis. It emphasizes mitochondrial rRNA modifications, where aberrant expression contributes to metabolic dysfunction and resistance to apoptosis. Challenges and future directions for targeting rRNA modifications are also evaluated, positioning them as a promising therapeutic

These chemical modifications transcend structural roles, critically shaping ribosome functionality and influencing cellular protein profiles. In this review, the mechanisms by which rRNA modifications regulate both rRNA functions and broader cellular physiological processes are critically discussed. Importantly, by altering the translational output, rRNA modifications can shift the cellular equilibrium towards oncogenesis, thus playing a key role in cancer development and progression. Moreover, a special focus is placed on the functions of mitochondrial rRNA modifications and their aberrant expression in cancer, an area with profound implications yet largely uncharted. Dysregulation in these modifications can lead to metabolic dysfunction and apoptosis resistance, hallmark traits of cancer cells.
