Cellular growth and division are two fundamental processes that are exquisitely sensitive and responsive to environmental fluctuations. One of the most energetically demanding functions of these processes is ribosome biogenesis, the key component to regulating overall protein synthesis and cell growth. Perturbations to ribosome biogenesis have been demonstrated to induce an acute stress response leading to p53 activation through the inhibition of Mdm2 by a number of ribosomal proteins. The energy status of a cell is a highly dynamic variable that naturally contributes to metabolic fluctuations, which can affect both the rates of ribosome biogenesis and p53 function. This, in turn, determines whether a cell is in an anabolic, growth-promoting state or a catabolic, growth-suppressing state. Here the authors integrate the known functions of p53 to postulate how changes in nutrient availability may induce the ribosomal protein-Mdm2-p53 signaling pathway to modulate p53-dependent metabolic regulation.
