Leukemia inhibitory factor (LIF) is a member of the IL-6 family of pleiotropic cytokines, which are extensively involved in modulating hematopoiesis and immunity. We have undertaken a detailed analysis of LIF genomic organization and gene transcription and investigated the proteins expressed from alternate transcripts. Previously unidentified LIF(More)
During embryogenesis the central and peripheral nervous systems arise from a neural precursor population, neurectoderm, formed during gastrulation. We demonstrate the differentiation of mouse embryonic stem cells to neurectoderm in culture, in a manner which recapitulates embryogenesis, with the sequential and homogeneous formation of primitive ectoderm,(More)
Although many growth factors and cytokines have been shown to be localized within the cell and nucleus, the mechanism by which these molecules elicit a biological response is not well understood. The cytokine leukemia inhibitory factor (LIF) provides a tractable experimental system to investigate this problem, because translation of alternatively spliced(More)
Nedd4 is a member of a growing family of ubiquitin-protein ligases which consist of a lipid-binding domain, two to four WW domains and a C-terminal ubiquitin-protein ligase domain. The Nedd4 mRNA levels are developmentally regulated and Nedd4 protein is highly expressed in many mouse embryonic tissues. In this study we have used a far-Western screen to(More)
During vertebrate embryogenesis, the somites form by segmentation of the trunk mesoderm, lateral to the neural tube, in an anterior to posterior direction. Analysis of differential gene expression during somitogenesis has been problematic due to the limited amount of tissue available from early mouse embryos. To circumvent these problems, we developed a(More)
Within the mammalian genome, there are many multimember gene families that encode membrane proteins with extracellular leucine rich repeats which are thought to act as cell adhesion or signalling molecules. We previously showed that the members of the NLRR gene family are expressed in a developmentally restricted manner in the mouse with NLRR-1 being(More)
We have analysed the expression during mid-gestation mouse development of the four member LRRTM gene family which encodes type 1 transmembrane proteins containing 10 extracellular leucine rich repeats and a short intracellular tail. Each family member has a developmentally regulated pattern of expression distinct from all other members. LRRTM1 is expressed(More)
Mitochondria play a critical role in cell survival and death after cerebral ischemia. Uncoupling proteins (UCPs) are inner mitochondrial membrane proteins that disperse the mitochondrial proton gradient by translocating H(+) across the inner membrane in order to stabilize the inner mitochondrial membrane potential (ΔΨ(m)) and reduce the formation of(More)
We have analysed the expression during mouse development of the four member Lingo/LERN gene family which encodes type 1 transmembrane proteins containing 12 extracellular leucine rich repeats, an immunoglobulin C2 domain and a short intracellular tail. Each family member has a distinct pattern of expression in the mouse embryo as is the case for the related(More)
