What controls the tips of our chromosomes? -- ScienceDaily
The researchers also showed that this process is identical both in yeast and in human cells. This means that the regulation of the "S" component has been conserved throughout evolution of species, which somehow reveals the importance of this process for the correct functioning of cells. This opens new avenues to the discovery of therapies capable of dealing with debilitating diseases associated to defects in telomeres. "The unanticipated role of this evolutionary conserved phosphatase is reminiscent of the regulation of the cell cycle by phosphatases that counteract the role of kinases, thus re-establishing the ground state of 'once and only once' cell cycle processes," says the investigator Miguel Godinho Ferreira. "With this work, we now understand better how telomere regulation works, a key process in cancer and ageing," says Jose Escandell, first author of the publication.
