Notch pathway has been demonstrated to regulate cardiovascular development. One important step in Notch pathway is the cleavage of Notch receptor, during which an intracellular fragment of Notch protein is released to activate downstream genes. It is still uncertain whether Adam10, the mammalian homologue of Kuzbanian in Drosophila, is required to activate(More)
Intracellular vesicle transport pathways are critical for neuronal survival and central nervous system development. The Vps-C complex regulates multiple vesicle transport pathways to the lysosome in lower organisms. However, little is known regarding its physiological function in mammals. We deleted Vps18, a central member of Vps-C core complex, in neural(More)
Mf2 (mesoderm/mesenchyme forkhead 2) encodes a forkhead/winged helix transcription factor expressed in numerous tissues of the mouse embryo, including paraxial mesoderm, somites, branchial arches, vibrissae, developing central nervous system, and developing kidney. We have generated mice homozygous for a null mutation in the Mf2 gene (Mf2(lacZ)) to examine(More)
Cytoplasmic dynein 1 is fundamentally important for transporting a variety of essential cargoes along microtubules within eukaryotic cells. However, in mammals, few mutants are available for studying the effects of defects in dynein-controlled processes in the context of the whole organism. Here, we deleted mouse Dlic1 gene encoding DLIC1, a subunit of the(More)
BACKGROUND Programmed cell death, or apoptosis, is a fundamental physiological process during normal development or in pathological conditions. The activation of apoptosis can be elicited by numerous signalling pathways. Ras is known to mediate anti-apoptotic signals by inhibiting Hid activity in the Drosophila eye. Here we report the isolation of a new(More)
The placenta is essential for survival and growth of the fetus because it promotes the delivery of nutrients and oxygen from the maternal circulation as well as fetal waste disposal. Mst1 and Mst2 (Mst1/2), key components of the mammalian hpo/Mst signaling pathway, encode two highly conserved Ser/Thr kinases and play important roles in the prevention of(More)
We demonstrate the feasibility of performing a systematic screen for human gene functions in Drosophila by assaying for their ability to induce overexpression phenotypes. Over 1 500 transgenic fly lines corresponding to 236 human genes have been established. In all, 51 lines are capable of eliciting a phenotype suggesting that the human genes are(More)
ADAM23, belonging to ADAM (A Disintegrin And Metalloprotease) protein family, is mainly expressed in brain. P19 cells could differentiate into neuroectodermal cell lineage after cell aggregates have been induced by retinoic acid (RA). In this report, we show that the post-transcriptional and post-translational processes of ADAM23 are regulated during the(More)
