MAPK signaling promotes embryonic neural induction and expression of embryonic patterning genes in Nematostella vectensis

ABSTRACT: While FGF mediated MEK/ERK signaling is required for apical tuft formation and metamorphosis in the sea anemone Nematostella vectensis (Rentzsch et al, 2008), nothing is known about the role of MEK/ERK signaling in inducing germ layers and cell types during early developmental stages. We therefore performed a genome wide expression array on UO126 (MEK inhibitor) treated blastula stages compared to DMSO treated control embryos and identified genes potentially involved in neurogenesis, germ layer specification and axial patterning.We performed transcriptional profiling of Nematostella vectensis blastula stages (24 hours post fertilisation @ 17C) using a custom made whole genome array (4x72K - A-MEXP-2380). DMSO treated wild-type embryos were compared to U0126 (MEK Inhibitor) treated embryos at the blastula stage.
