"One of the symmetry breaking events in mouse gastrulation requires the amplification of Nodal on the side of the embryo opposite to the Anterior Visceral Endoderm (AVE). Describe one way by which Nodal gets amplified in this region."
My understanding of this is that there are a few ways nodal is amplified though I'm not sure if this is specifically occurs on the opposite side of the AVE.
1. pronodal cleaved by protease -> active nodal
2. Nodal -> BMP4 -> Wnt-> nodal
3. Nodal-> Nodal, Fox1 binding site
4. BMP4 on outside-> nodal
Are all of these occuring opposite to AVE?

What is the phenotype, and why is the phenotype so similar? Is the phenotype going to be that there is a disruption of the formation of the neural tube for both of these because bottle cell formation is necessary for the neural plate to fold in forming the neural tube and Shroom3 is further needed to close the neural plate? So since both Plekhg5 and Shroom3 are used in forming the neural tube, injecting the mRNA will just lead to neural tube deformity?arrow_forwardWhat are some medical issues or health trends that may have a direct link to the idea of keeping fat out of diets?arrow_forward
