Resumen
Las células tumorales resisten la apoptosis y pueden revertir la muerte celular, un proceso llamado anastasis. Las células madre mesenquimales (MSC) mostraron anastasis después del tratamiento con etanol o doxorrubicina, pero no con estaurosporina.
Área de la Ciencia:
- Biología celular
- Investigación del cáncer
- Biología de células madre
Sus antecedentes:
- Las células tumorales evaden la apoptosis para la supervivencia y la metástasis.
- La anastasis describe la reversibilidad de la muerte celular.
- Las células madre mesenquimales (MSC) muestran resistencia a la apoptosis.
Objetivo del estudio:
- Investigar la anastasis en células mesenquimales humanas.
- Determinar el efecto de los inductores de muerte celular en la anastasis.
Principales métodos:
- Exposición de MSC hepáticas humanas, MSC placentarias y fibroblastos de la piel a etanol, estaurosporina o doxorrubicina.
- Observación de la morfología celular y la proliferación post-tratamiento.
Principales resultados:
- Las células mesenquimales demostraron anastasis tras el tratamiento con dosis no letales de etanol.
- Bajas concentraciones de doxorrubicina también indujeron muerte celular reversible (anastasis).
- Las concentraciones no letales de estaurosporina dieron lugar a efectos citostáticos irreversibles, no a anastasis.
Conclusiones:
- Las células mesenquimales pueden sufrir anastasis, revirtiendo la muerte celular bajo condiciones específicas.
- La reversibilidad de la muerte celular depende del inductor y su concentración.
- La anastasis puede representar un mecanismo de supervivencia en células mesenquimales, distinto de la citostasis inducida por estaurosporina.

According to obedience research, we may harm others under the forceful pressures of an authority figure (Milgram, 1974). How about if the inappropriate orders were delivered with less force? The increasing interdependence between nurses and physicians compelled Hofling and his colleagues to explore nurses’ reactions to a potentially harmful medical request made by the perceived authority figure, the doctor (Hofling, Brotzman, Dalrymple, Graves, & Pierce, 1966). In this situation,...

Social psychologists have documented that feeling good about ourselves and maintaining positive self-esteem is a powerful motivator of human behavior (Tavris & Aronson, 2008). In the United States, members of the predominant culture typically think very highly of themselves and view themselves as good people who are above average on many desirable traits (Ehrlinger, Gilovich, & Ross, 2005). Often, our behavior, attitudes, and beliefs are affected when we experience a threat to our...

According to Charles Cooley, we base our image on what we think other people see (Cooley 1902). We imagine how we must appear to others, then react to this speculation. We don certain clothes, prepare our hair in a particular manner, wear makeup, use cologne, and the like—all with the notion that our presentation of ourselves is going to affect how others perceive us. We expect a certain reaction, and, if lucky, we get the one we desire and feel good about it. But more than that, Cooley...

Ideally, the people who observe and record the children’s behavior are unaware of who was assigned to the experimental or control group, in order to control for experimenter bias. Experimenter bias refers to the possibility that a researcher’s expectations might skew the results of the study. Remember, conducting an experiment requires a lot of planning, and the people involved in the research project have a vested interest in supporting their hypotheses. If the observers knew which...
