Progressive ankylosis gene (ank) regulates osteoblast differentiation.
The progressive ankylosis gene (ank) is a transmembrane protein that transports intracellular pyrophosphate to the extracellular milieu. Human mutations of ank lead to craniometaphyseal dysplasia, a disease which is characterized by the overgrowth of craniofacial bones and osteopenia in long bones, suggesting that ANK plays a regulatory role in osteoblast differentiation. To determine the role ...
متن کاملRole of the progressive ankylosis gene in cartilage mineralization.
PURPOSE OF REVIEW Among the myriad of players in the calcification of cartilage, ANK is a relatively new entrant. It is a multipass transmembrane protein that regulates the transport of inorganic pyrophosphate between the cell and the extracellular space. Mutations in ANK result in two distinct calcification disorders: craniometaphyseal dysplasia and familial calcium pyrophosphate dihydrate dep...
متن کاملTotal Ankylosis of the Upper Left Limb: A Case of Progressive Osseous Heteroplasia
Progressive osseous heteroplasia is a rare inherited disease that begins with skin ossification and proceeds into the deeper connective tissues. The disease should be distinguished from other genetic disorders of heterotopic ossification including fibrodysplasia ossificans progressiva (FOP) and Albright hereditary osteodystrophy (AHO). We report a case of progressive osseous heteroplasia in a...
متن کاملThe progressive ankylosis gene product ANK regulates extracellular ATP levels in primary articular chondrocytes
INTRODUCTION Extracellular ATP (eATP) is released by articular chondrocytes under physiological and pathological conditions. High eATP levels cause pathologic calcification, damage cartilage, and mediate pain. We recently showed that stable over-expression of the progressive ankylosis gene product, ANK, increased chondrocyte eATP levels, but the mechanisms of this effect remained unexplored. Th...
متن کاملProgressive Ankylosis Protein (ANK) in Osteoblasts and Osteoclasts Controls Bone Formation and Bone Remodeling
The progressive ankylosis gene (ank) encodes a transmembrane protein that transports intracellular inorganic pyrophosphate (PP(i)) to the extracellular milieu. ank/ank mice, which express a truncated nonfunctional ANK, showed a markedly reduced bone mass, bone-formation rate, and number of tartrate-resistant acid phosphatase-positive (TRAP(+)) multinucleated osteoclasts. ANK function deficiency...
