Essential role of RSK2 in c-Fos–dependent osteosarcoma development

David, Jean-Pierre, Mehic, Denis, Bakiri, Latifa, Schilling, Arndt F., Mandic, Vice, Priemel, Matthias, ...

Inactivation of the growth factor–regulated S6 kinase RSK2 causes Coffin-Lowry syndrome in humans, an X-linked mental retardation condition associated with progressive skeletal abnormalities. Here...

Fhl2 deficiency results in osteopenia due to decreased activity of osteoblasts

Günther, Thomas, Poli, Cecilia, Müller, Judith M, Catala-Lehnen, Philip, Schinke, Thorsten, Yin, Na, ...

Osteoporosis is one of the major health problems today, yet little is known about the loss of bone mass caused by reduced activity of the bone-forming osteoblasts. Here we show that mice deficient...

The high mobility group transcription factor Sox8 is a negative regulator of osteoblast differentiation

Schmidt, Katy, Schinke, Thorsten, Haberland, Michael, Priemel, Matthias, Schilling, Arndt F., Mueldner, Cordula, ...

Bone remodeling is an important physiologic process that is required to maintain a constant bone mass. This is achieved through a balanced activity of bone-resorbing osteoclasts and bone-forming...

Mice lacking JunB are osteopenic due to cell-autonomous osteoblast and osteoclast defects

Kenner, Lukas, Hoebertz, Astrid, Beil, Timo, Keon, Niamh, Karreth, Florian, Eferl, Robert, ...
