Abstract
This review addresses the relationship between the structural changes and functional activity of the nucleolus, and ribosome biogenesis in the initiation and progression of cancer. To prepare this review, an electronic systematic search of review and original research articles was conducted in the PubMed database, focusing on studies of the nucleolar apparatus in tumor growth. The literature search was performed in English using the following key terms: nucleolus, nucleolar stress, ribosome biogenesis, and cancer. The mechanisms underlying nucleolar stress and the molecular pathways leading to nucleolar apparatus dysfunction during tumorigenesis are discussed. It is shown that nucleolar dysfunction and accelerated ribosome biogenesis result from mutations and alterations in the expression of tumor suppressors, oncogenes, and cell cycle regulators. An increase in the number and size of nucleoli is identified as an important prognostic factor in cancers. Dysregulation of nucleolar function and structural alterations of ribosomes play a substantial role in cancer pathogenesis in the context of ribosomopathies and viral diseases. Investigation into the molecular mechanisms underlying nucleolar abnormalities, ribosome biogenesis, and ribosomal dysfunction may facilitate the development of novel targeted anticancer therapies.
