Název v původním jazyce

The role of actin in the apoptotic cell death of P19 embryonal carcinoma cells.

Popis výsledku v původním jazyce

The P19 mouse embryonal carcinoma cell line was used as a model for a study of apoptosis accompanying differentiation induced by all-trans retinoic acid (ATRA). Apoptosis was detected both on the basis of morphological features (nuclear fragmentation, blebbing of plasma membrane, and formation of apoptotic bodies), and by using DNA electrophoresis and flow-cytometric measurement of DNA content. Actin cytoskeleton was studied both on morphological and submicroscopic levels. ATRA-treated cells manifestedapoptosis-specific changes in the distribution of actin foremost in association with their entry into executive phase of apoptosis, when F-actin cables participated in cell disintegration into apoptotic bodies. Using immunogold labeling, actin was also identified in centers of fragmenting apoptotic nuclei, in the disintegration of which it is likely involved as well. At the same time, a cleavage of actin by active caspase-3 was proved, resulting in the emergence of 32kDa fragment termed
