La longitud del telómero y la actividad de la telomerasa, una Yin y Yang de la senescencia celular

In some cells, binding of trophic factors stimulates PI-3 kinase activity, leading to activation of the downstream kinase Akt, which phosphorylates Bad. Preparar diluciones seriadas 1: The Birth and Death of Cells. Cancer and the Cell Cycle: Click here for the english version. Synthesis of the leading strand, catalyzed by DNA polymerase III, occurs by sequential addition of deoxyribonucleotides in the same direction as movement of the growing fork. Regulators either promote or suppress apoptosis; the two regulators shown here, CED-9 and Bcl-2, both function to suppress apoptosis in the presence of trophic factors.

Clearly visible in the latter are dense spheres of compacted chromatin as the nucleus begins to fragment.

A family of cysteine proteases serve as effector proteins; their activation leads to degradation of various intracellular substrates and eventually cell death. Adapters interact with both regulators and effectors; in the absence of trophic factors, they promote activation of effectors.
