Paget's disease of bone is generally diagnosed in individuals aged >50 years, usually manifests in one or several bones and is initiated by osteoclast-induced osteolytic lesions. Subsequently, over a period of many years, osteoblastic activity can result in sclerosis and deformation of bone. The prevalence of Paget's disease is highest in the UK and in countries where a large number of residents have ancestors from the UK. Currently, in many countries, the prevalence of the disorder has decreased. A considerable number of affected patients have a family history of Paget's disease and the disorder has an autosomal dominant pattern of inheritance but with incomplete penetrance. A large number of mutations in SQSTM1 (which encodes sequestosome-1; also known as ubiquitin-binding protein p62) seem to account for the susceptibility to develop Paget's disease in some families; the involvement of other genes is currently under investigation. In addition to a genetic cause, environmental factors have been proposed to have a role in the pathogenesis of Paget's disease. Although most evidence has been presented for measles virus as an aetiologic factor, some studies have not confirmed its involvement. The decreasing incidence of Paget's disease, which could be attributed to measles vaccination along with the measles virus nucleocapsid protein induction of Paget's disease lesions in transgenic mice, supports an aetiologic role of the virus. © 2015 Macmillan Publishers Limited.

Studies of the etiology of Paget's disease have focused separately on the viral and genetic components of the disease. In this issue of Cell Metabolism, Kurihara et al. (2011) join these components, reporting that sequestosome 1 mutation in patients and mice activates osteoclasts, while measles virus induces the phenotype of Paget's disease. © 2011 Elsevier Inc.

Glucosylceramide has a unique and often ambiguous role in mammalian cells. Activation of glucosylceramide synthase, the enzyme that places a glucosyl moiety onto ceramide, is the first pathway-committed step to the production of more complex glycosphingolipids such as lactosylceramide and gangliosides. Alterations in the level of glucosylceramide are noted in cells and tissues in response to cardiovascular disease, diabetes, skin disorders and cancer. Overall, upregulation of glucosylceramide offers cellular protection and primes certain cells for proliferation. However, prolonged overabundance of glucosylceramide is detrimental, as seen in Gaucher disease in humans. © 2010 Landes Bioscience and Springer Science+Business Media.

The invention relates generally to in vivo collection of circulating molecules, tumor cells and other biological markers using a collecting probe. The probe is configured for placement within a living organism for an extended period of time to provide sufficient yield of biological marker for analysis.
