miR-34s keep osteoblasts bone idle
miR-34s keep osteoblasts bone idle T he development of bone-forming osteoblasts is controlled by transcription factors such as Runx2, Osterix, and ATF4, which, in turn, are regulated by a variety of nuclear proteins that inhibit or activate these factors. miRNAs have also been implicated in osteoblast differentiation, though little is known about the effects of individual miRNAs on skeletogenes...
متن کاملmiR-34s inhibit osteoblast proliferation and differentiation in the mouse by targeting SATB2
A screen of microRNAs preferentially expressed in osteoblasts identified members of the miR-34 family as regulators of osteoblast proliferation and/or differentiation. Osteoblast-specific gain- and loss-of-function experiments performed in vivo revealed that miR-34b and -c affected skeletogenesis during embryonic development, as well as bone mass accrual after birth, through two complementary c...
متن کاملOsteoblasts in Bone Physiology—Mini Review
Bone structural integrity and shape are maintained by removal of old matrix by osteoclasts and in-situ synthesis of new bone by osteoblasts. These cells comprise the basic multicellular unit (BMU). Bone mass maintenance is determined by the net anabolic activity of the BMU, when the matrix elaboration of the osteoblasts equals or exceeds the bone resorption by the osteoclasts. The normal functi...
متن کاملThe role of osteoblasts in bone metastasis
The primary role of osteoblasts is to lay down new bone during skeletal development and remodelling. Throughout this process osteoblasts directly interact with other cell types within bone, including osteocytes and haematopoietic stem cells. Osteoblastic cells also signal indirectly to bone-resorbing osteoclasts via the secretion of RANKL. Through these mechanisms, cells of the osteoblast linea...
متن کاملSodium Arsenite Caused Mineralization Impairment in Rat Bone Marrow Mesenchymal Stem Cells Differentiating to Osteoblasts
ABSTRACT Background: Sodium arsenite (SA) recently has been recommended to be used in malignancy therapy. Our studies showed, SA in short and long period of treatment caused reduction of rats Bone Marrow Mesenchymal Stem Cells (MSCs) viability and induced caspase dependent apoptosis. The aim of this study was to investigate the effect of SA on osteogenic differentiation of MSCs. Methods: MSCs...
