The TGF-β superfamily of growth factors is known to transmit signals to the nucleus mainly through the Smads, intracellular signaling components that are highly conserved from nematodes to humans. The signaling activity of the Smads is regulated by their ligand-stimulated phosphorylation through Ser/Thr kinase receptors. Here, to examine the in vivo role of BMP, we investigated the spatio-temporal...
Lens regeneration from non-lens ocular tissues has been well documented in amphibians, from the dorsal iris in the newt and from the outer cornea in Xenopus. To understand the early molecular events which govern lens regeneration, we examined the expression of two early marker genes of normal lens development, Pax-6 and Prox 1. In both Cynops (newt) iris and Xenopus cornea, Pax-6 is expressed soon...
