The only difference is that while the rate of progression of the wave of expression of these other clock genes is much faster in the posterior than the anterior PSM, that of Sprouty4 appears uniform along the whole length of the mouse PSM (Figure 1F).
As a first consideration, within some organs composed of macroscopic portions each having its own structure uneven obstacles are opposed to the progression of the shear waves, similarly to the differences in the acoustic impedance regulating the transmission of US beams.
This partial repression still allows the progression of N-signalling waves through the Pa-cad domain, but only allows the formation of segmental N-signalling stripes outside it.
For example, for the classic inflammatory transcription factor gene NFKB1, GRO-seq reveals the time-dependent progression of Pol II waves moving from the 5′ to 3′ end of the transcription unit during the TNFα-treatment time course, information that can be used to determine rates of transcription (~3 kb per minute in the case of NFKB1; [ 19]).
Figure 6 A, B show further examples of the progressions of the wave-fronts calculated from the path taken by the wave-fronts from the retinotopic site of the square at its offset to the retinotopic site of the next square at its onset.
On June 16, the formation of an upper-level low over the Bay of Campeche and the progression of a tropical wave across the Caribbean Sea helped foster the development of a low-pressure area over the Yucatán Peninsula.
We provide evidence that STC1 sensitized the cells to ATP upstream of PLC, and that blocking endogenous STC1 using a neutralizing antibody inhibited progression of the calcium wave.
The viral plaque is formed by the progression of an infection wave across the monolayer of cells [42] whose constant velocity is determined by the infection kinetics averaged over many thousands of cells.
The stochastic nature of mutation, and the distribution of fitness effects of these mutations, regulates the breathing and faltering progression of the traveling wave.
During L3, ecdysone downregulates Delta in the NE, thus accelerating progression of the proneural wave that regulates the balance between proliferation and neurogenesis.
