Many human pathological conditions, not linked to genetic alterations of oncogenes or tumor suppressors, are nevertheless associated with an increased risk of developing cancer, and some of them are characterized by quantitative and/or qualitative changes in ribosome biogenesis. Indeed, there is evidence that both an up-regulation of ribosome biogenesis, such as that occurring during the abnormal stimulation of cell growth, and intrinsic dysfunctions of ribosomes, such as those characterizing a series of inherited disorders, show an increased incidence of tumor onset. Here we discuss some recent insights into the mechanisms by which these alterations in ribosome biogenesis may facilitate tumorigenesis.

Changes in ribosome biogenesis may induce cancer by down-regulating the cell tumor suppressor potential.

Abstract

Many human pathological conditions, not linked to genetic alterations of oncogenes or tumor suppressors, are nevertheless associated with an increased risk of developing cancer, and some of them are characterized by quantitative and/or qualitative changes in ribosome biogenesis. Indeed, there is evidence that both an up-regulation of ribosome biogenesis, such as that occurring during the abnormal stimulation of cell growth, and intrinsic dysfunctions of ribosomes, such as those characterizing a series of inherited disorders, show an increased incidence of tumor onset. Here we discuss some recent insights into the mechanisms by which these alterations in ribosome biogenesis may facilitate tumorigenesis.
