Osteoarthritis is a chronic degenerative disease associated with joint pain and loss of joint function. It has an estimated incidence of 4 out of every 100 people and significantly reduces the quality of life in affected individuals. The major symptoms are chronic pain, swelling and stiffness; severe, chronic joint pain is often the central factor that causes patients to seek medical attention. Within the affected joint, there is focal degradation and remodelling of articular cartilage, new bone formation (osteophytes) and mild synovitis.

Several mechanisms are thought to contribute to...

Brings together a cross-fertilization of ideas between human molecular genetics, develeopmental biology, tissue biology and the biochemistry of cell signalling pathways, in order to create new insights into the mechanisms of normal and abnormal skeletogenesis.

Nature employs a wide variety of sex determining mechanisms and it is only comparatively recently that the tools have become available for these to be explored at the cellular and molecular levels. A major landmark was the discovery in 1990 of the SRY gene and the subsequent demonstration of its key role in triggering male sex determination in transgenic mice.

This book reviews and discusses our current understanding of the molecular genetic pathways of sex determination, with special emphasis on vertebrates. It features comparisons with other modes of sex determination,...
