Porque razão param as células de se multiplicar? E porque razão às vezes se multiplicam sem controle (cancro)? O que faz variar essa taxa de multiplicação ou replicação? Uma descoberta recente traz nova luz sobre esta questão vital e pode abrir rumo a melhores respostas e compreensão do ciclo celular.
Why do cells multiply? And why at different rates? Why do they stop multiplying (die)? And why do they multiply to fast (cancer)? The article below sheds new light and maybe some answers on this extremely important questions.
Interistingly I have had a similar suggestion, that some RNA could act has a counter or a register, based on how computer code works, which is actually not so far off...
A switch between life and death from PhysOrg.com
Cells in an embryo divide at an amazing rate to build a whole body, but this growth needs to be controlled. Otherwise the result may be defects in embryonic development or cancer in adults. Controlling growth requires that some cells divide while others die; their fates are determined by signals that are passed from molecule to molecule within the cell. Researchers at the European Molecular Biology Laboratory (EMBL) in Heidelberg have now discovered how one of these signaling pathways controls the life and death of cells in the fruit fly. [...]
