Ribosomopathy - Wikipedia
Cancer cells have irregularly shaped, large nucleoli, which may correspond ribosomal gene transcription up-regulation, and hence high cell proliferation. Oncogenes, like c-Myc, can upregulate rDNA transcription in a direct and indirect fashion. Tumor suppressors like Rb and p53, on the other hand, can suppress ribosome biogenesis. Additionally, the nucleolus is an important cellular sensor for stress and plays a key role in the activation of p53. WebMar 19, 2014 · However, it has become clear that the specificity and activity of the ribosome is regulated, and changes to its composition may begin to explain the heterogeneity among ribosomopathies.
