Cooperative activity of noggin and gremlin 1 in axial skeleton development.
Inductive signals from adjacent tissues initiate differentiation within the somite. In this study, we used mouse embryos mutant for the BMP antagonists noggin (Nog) and gremlin 1 (Grem1) to characterize the effects of BMP signaling on the specification of the sclerotome. We confirmed reduction of Pax1 and Pax9 expression in Nog mutants, but found that Nog;Grem1 double mutants completely fail to...
متن کاملFollistatin interacts with Noggin in the development of the axial skeleton
When compared to single mutants for Follistatin or Noggin, we find that double mutants display a dramatic further reduction in trunk cartilage formation, particularly in the vertebral bodies and proximal ribs. Consistent with these observations, expression of the early sclerotome markers Pax1 and Uncx is diminished in Noggin;Follistatin compound mutants. In contrast, Sim1 expression expands med...
متن کاملThe role of Pax-1 in axial skeleton development.
Previous studies have identified a single amino-acid substitution in the transcriptional regulator Pax-1 as the cause of the mouse skeletal mutant undulated (un). To evaluate the role of Pax-1 in the formation of the axial skeleton we have studied Pax-1 protein expression in early sclerotome cells and during subsequent embryonic development, and we have characterized the phenotype of three diff...
متن کاملThe expression patterns of gremlin 1 and noggin in normal adult and tumor tissues.
Gremlin 1 and noggin are inhibitors of bone morphogenetic protein (BMP) signaling. They are vital during early development but their role in adult tissues has remained largely unresolved. The BMP signaling pathway has also been implicated in tumorigenesis, however with emphasis on the role of the ligands and receptors. We performed a concurrent survey of gremlin 1 and noggin protein expression ...

این پژوهش با هدف "بررسی وضعیت موجود آموزش عالی مجازی در ایران و راههای توسعه و ارتقای آن " و با روش توصیفی-تحلیلی و پیمایشی صورت پذیرفته است. بررسی اسنادو مدارک موجود در زمینه آموزش مجازی نشان داد تعداد دانشجویان و مقاطع تحصیلی و رشته محل های دوره های الکترونیکی چندان مطلوب نبوده و از نظر کیفی نیز وضعیت شاخص خدمات آموزشی اساتید و وضعیت شبکه اینترنت در محیط آموزش مجازی نامطلوب است.
