Making waves
Each transcriptional wave from a yeast cell cycle promoter lasts 20–25 min; so stringing together 3 or 4 of them should allow the construction of a simple 90-min cell cycle. But, says van Oudenaarden, " if you didn't optimize the system, the cell cycle waves get washed out very easily. Within a quarter or a third of a 90-minute cycle, the waves are almost completely gone. " Rather than investig...
متن کاملMaking waves with hairs.
The skin is like a canvas. Pigment distribution, skin appendages, skin ridges, etc. are arranged on the skin surface. The arrangement may be random but every now and then they form specific patterns. In some occasions, the specific arrangement is important for organism function or message display. In all occasions, these distinct arrays provide us with windows into the fundamental processes of ...
متن کاملCell Migration: Making the Waves
Coordinated changes of cell shape are often the result of the excitable, wave-like dynamics of the actin cytoskeleton. New work shows that, in migrating cells, protrusion waves arise from mechanochemical crosstalk between adhesion sites, membrane tension and the actin protrusive machinery.
