Digital control circuitry of cancer cell and its apoptosis

2009

This study, through a typical aerospace systems architecture, suggests an engineering design of a human cancer cell circuitry in which a digital optimal control matrix is assigned to repair the DNA damage level and/or to trigger its apoptosis. Here, the conceived machinery is proposed taking into account the state of the art in cancer investigation. However, it could be further generalized. The most recent studies on cancer pathologies give a predominant role to the oncosuppressor protein p53 and its antagonist, the oncogene Mdm2. Experimental and theoretical approaches are in agreement in deducing a “digital” response of the p53 when genomic integrity is damaged. Once DNA damage is present…
