Spatial changes in poly(A) concentrations during early embryogenesis in Xenopus laevis: analysis by in situ hybridization.

abstract：:The Hedgehog (Hh) signal transduction pathway plays a central role in the development of invertebrates and vertebrates. While much is known about the pathway, the role of Suppressor of fused (Su(fu)), a component of the pathway's signaling complex has remained enigmatic. Previous studies have linked Su(fu) to the cyto...
