Mitosis: Don't get mad, get even
The 'mitotic spindle checkpoint' ensures that, before a cell exits from mitosis, all of its chromosomes are aligned on the spindle to form the metaphase plate. Mad2 is an essential component of this checkpoint system and it binds specifically to unattached kinetochores.
متن کاملSenescence: Even Bacteria Get Old
Cellular senescence, even in the presence of abundant nutrients, has now been demonstrated in several microbes, including most recently the bacterium Escherichia coli, suggesting that it may be a universal adaptive response to the inevitable damage to cell constituents that accumulates with time.
متن کاملCheckpoint Activation: Don't Get Mad Too Much
The Mad2 protein is required to delay sister chromatid separation until all chromosomes have been aligned on the mitotic spindle. Two recent studies provide new insights into how Mad2 contributes to this remarkable task.
متن کاملHow to get even with desires ∗
The scalar particle even imposes a constraint on the likelihood of its prejacent and the alternatives on which it operates. This semantic import of even restricts its distribution: even that associates with a weak predicate in its immediate surface scope – weak even, for short – is acceptable only if it is appropriately embedded (cf. Lahiri 1998). This paper investigates the occurrence of weak ...
متن کاملWhen to get mad: adaptive significance of rage in animals.
The wide distribution of rage in animals suggests that rage should have an adaptive significance. In the present work, the function of rage is explored under an evolutionary perspective. I try to assess the selective advantage conferred to the individual presenting rage compared to one that does not. In this work, I considered animals under the 'strategist' perspective rather than the 'stimulus...
