Gastrulation is a morphogenetic process in which tightly coordinated cell and tissue movements establish the three germ layers (ectoderm, mesoderm, and endoderm) to define the anterior-to-posterior embryonic organization [1]. To elicit this movement, cells modulate membrane protrusions and undergo dynamic cell interactions. Here we report that ankyrin repeats domain protein 5 (xANR5), a novel FGF...
We used cDNA microarray analysis to screen for FGF target genes in Xenopus embryos treated with the FGFR1 inhibitor SU5402, and identified neurotrophin receptor homolog (NRH) as an FGF target. Causing gain of NRH function by NRH mRNA or loss of NRH function using a Morpholino antisense-oligonucleotide (Mo) led to gastrulation defects without affecting mesoderm differentiation. Depletion of NRH by...
