Mf1, which encodes a winged-helix/forkhead transcription factor, is the murine homolog of human FKHL7, mutated in individuals with autosomal dominant inherited dysgenesis of the anterior segment of the eye (Axenfeld-Reiger anomaly). Mouse embryos homozygous for null mutations in Mf1 (Mf1(lacZ) and Mf1(ch)) show severely abnormal development of the anterior(More)
The murine genes, Foxc1 and Foxc2 (previously, Mf1 and Mfh1), encode forkhead/winged helix transcription factors with virtually identical DNA-binding domains and overlapping expression patterns in various embryonic tissues. Foxc1/Mf1 is disrupted in the mutant, congenital hydrocephalus (Foxc1/Mf1(ch)), which has multiple developmental defects. We show here(More)
Bone morphogenetic protein 8B (BMP8B) is a member of the TGFbeta superfamily of growth factors. In the mouse, Bmp8b is expressed in male germ cells of the testis and trophoblast cells of the placenta, suggesting that it has a role in spermatogenesis and reproduction. To investigate these possibilities, we have generated mice with a targeted mutation in(More)
The murine Mf1 and Mfh1 genes have overlapping patterns of expression in the embryo and encode forkhead/winged helix transcription factors with virtually identical DNA binding domains. Previous studies have shown that Mfh1 null mutants have severe cardiovascular defects, including interruptions and coarctations of the aortic arch and ventricular septal(More)
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)
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)
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)
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)
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)
Excessive activation of dendritic cells (DCs) leads to the development of autoimmune and inflammatory diseases, which has prompted a search for regulators of DC activation. Here we report that Rhbdd3, a member of the rhomboid family of proteases, suppressed the activation of DCs and production of interleukin 6 (IL-6) triggered by Toll-like receptors (TLRs).(More)
