Post transcriptional control of SMN2 expression
RNA regulation in the somite clock
The formation of somites, during embryonic development, is highly regulated both temporally and spatially. The main effectors of this regulation are a set of cyclic genes, that display an oscillating pattern of expression, and a morphogenetic gradient, which constitutes the wavefront of differentiation. Wilts the oscillating behavior of the cyclic genes requires a certain instability at the mRNA level, the wavefront gradient is formed by the slow degradation of mRNA. Our aim is the study and characterization of the mechanisms that regulate mRNA stability in this context. Using Zebrafish as a model organism, we are combining bioinformatic and biochemical approaches with in vivo studies.
