LRP5 and Wnt signaling: a union made for bone.
THE IDENTIFICATION OF mutations in the human lowdensity lipoprotein (LDL) receptor–related protein 5 (LRP5) gene that give rise to conditions of low bone mass and increased bone mass has brought what just a few years ago were two seemingly unrelated fields crashing together, namely bone biology and Wnt signaling. It is now clear that the Wnt signaling pathway is another key pathway involved in ...

متن کاملPopulation bottlenecks
What are they? They occur when a wild population is reduced to a small number of individuals, and then increases again. They are typically caused by an environmental change such as unusual climatic conditions, or, increasingly, the actions of humans, as in over-hunting and habitat destruction. But if the population size is restored, everything ends up fine, surely? No. The small population size...
متن کاملSurmounting collectively oscillating bottlenecks
We study the collective escape dynamics of a chain of coupled, weakly damped nonlinear oscillators from a metastable state over a barrier when driven by a thermal heat bath in combination with a weak, globally acting periodic perturbation. Optimal parameter choices are identified that lead to a drastic enhancement of escape rates as compared to a pure noise-assisted situation. We elucidate the ...
