The paper proposes a model in terms of metabolic P graphs of a few important processes occurring during the biological phase where the choice is made to begin again mitosis or to arrest it. The cellular processes during this phase turn out to be especially interesting in the case of DNA damage, which triggers a specific destruction of Cdc24A phosphatase. It has important implications to understand the role of cell cycle checkpoints and the mechanisms guiding the proliferation of UV-resistant tumored cells.

Abstract

The paper proposes a model in terms of metabolic P graphs of a few important processes occurring during the biological phase where the choice is made to begin again mitosis or to arrest it. The cellular processes during this phase turn out to be especially interesting in the case of DNA damage, which triggers a specific destruction of Cdc24A phosphatase. It has important implications to understand the role of cell cycle checkpoints and the mechanisms guiding the proliferation of UV-resistant tumored cells.

This paper proposes a model in terms of metabolic P graphs of a few important processes occurring during the biological phase where the choice is made to begin again mitosis or to arrest it. The cellular processes during this phase turn out to be especially interesting in the case of DNA damage, which triggers a specific destruction of Cdc25A phosphatase. It has important implications to understand the role of cell cycle checkpoints and the mechanism(s) guiding the proliferation of UV-resistant tumored cells. The formalism of metabolic P graphs highlights the relevant information of the biological network dynamics, and the individuation of few parameters rules the basic mechanisms of Cdc25A degradation, involving a couple of important mitotic oscillators.
