Osteoporosis is one of the most common degenerative diseases. It is characterized by reduced bone mineral density (BMD) with an increased risk for bone fractures. There is a substantial genetic contribution to BMD, although the genetic factors involved in the pathogenesis of human osteoporosis are

The central nervous system plays an important role in regulating bone metabolism in health and in disease with a number of neurotransmitters been reported to influence bone cell activity through a central relay. In keeping with this, recent studies demonstrated that endocannabinoids and their

A substantial proportion of men with prostatic disease have an increased risk of bone loss. In the present study, we investigated the effects of Rubus coreanus Miquel (RCM) extracts on osteoporosis that occurs with N-methyl-N-nitrosourea (MNU)-induced prostatic hyperplasia. The rats used in this

Osteoporosis is a common health problem. The endocannabinoid pathway has been implicated as an important regulator of bone turnover. Rimonabant is a potent cannabinoid receptor1 (CB1) receptor antagonist with wide therapeutic use as an antiobesity drug that has been withdrawn due to side effects in

Age-related osteoporosis is characterized by reduced bone formation and accumulation of fat in the bone marrow compartment. Here, we report that the type 1 cannabinoid receptor (CB1) regulates this process. Mice with CB1 deficiency (CB1(-/-)) had increased peak bone mass due to reduced bone

Cannabinoid-based drugs modeled on cannabinoids originally isolated from marijuana are now known to significantly impact the functioning of the endocannabinoid system of mammals. This system operates not only in the brain but also in organs and tissues in the periphery including the immune system.

A functional endocannabinoid system is present in several mammalian organs and tissues. Recently, endocannabinoids and their receptors have been reported in the skeleton. Osteoblasts, the bone forming cells, and osteoclasts, the bone resorbing cells, produce the endocannabinoids anandamide and

The active component of marijuana, Delta(9)-tetrahydrocannabinol, activates the CB1 and CB2 cannabinoid receptors, thus mimicking the action of endogenous cannabinoids. CB1 is predominantly neuronal and mediates the cannabinoid psychotropic effects. CB2 is predominantly expressed in peripheral

Cannabis use is common, controversial and its clinical toxicology is likely under-recognised. A 56-year-old man presented with disabling shortness of breath. He smoked up to 7 g cannabis daily for 25 years (maximum 63 875 g) plus large amounts of hashish oil. Chest x ray suggested giant bullae. CT

Dental implants have been widely inserted in jaw bones as substitutes for teeth to restore oral function over the last few decades, but there still remains a major challenge in difficult clinical situations with poor bone quality and quantity or some diseases like osteoporosis. In the meantime, the

Much progress has been achieved in cannabinoid research. A major breakthrough in marijuana-cannabinoid research has been the discovery of a previously unknown but elaborate endogenous endocannabinoid system (ECS), complete with endocannabinoids and enzymes for their biosynthesis and degradation with

A number of recent preclinical studies have demonstrated the potential role of cannabinoids and their receptors in bone metabolism. Pharmacological and genetic modulation of cannabinoid receptors indicate that cannabinoid ligands may provide attractive and novel agents for the treatment of bone

The field of cannabinoid (CB) drug research is experiencing a challenge as the CB(1) antagonist Rimonabant, launched in 2006 as an anorectic/anti-obesity drug, was withdrawn from the European market due to the complications of suicide and depression as side effects. There is interest in developing

Genetic variants within the CNR2 gene encoding the cannabinoid receptor CB2 have been shown to be associated with osteoporosis and low bone mineral density (BMD) in case-control studies. We now examined the association of polymorphisms in CNR2 with hand bone strength in an ethnically homogeneous
