Diacylglycerol (DAG) lipase activity is required for axonal growth during development and for retrograde synaptic signaling at mature synapses. This enzyme synthesizes the endocannabinoid 2-arachidonoyl-glycerol (2-AG), and the CB1 cannabinoid receptor is also required for the above responses. We now report on the cloning and enzymatic characterization of(More)
A chimeric molecule consisting of the extracellular domain of the adhesion molecule, N-cadherin, fused to the Fc region of human IgG (NCAD-Fc) supports calcium-dependent cell adhesion and promotes neurite outgrowth following affinity-capture to a tissue culture substrate. When presented to cerebellar neurons as a soluble molecule, the NCAD-Fc stimulated(More)
Endocannabinoids (eCBs) function as retrograde signaling molecules at synapses throughout the brain, regulate axonal growth and guidance during development, and drive adult neurogenesis. There remains a lack of genetic evidence as to the identity of the enzyme(s) responsible for the synthesis of eCBs in the brain. Diacylglycerol lipase-alpha (DAGLalpha) and(More)
Interactions between the neural cell adhesion molecules NCAM and N-cadherin with the fibroblast growth factor receptor (FGFR) are important for a number of developmental events and have also been implicated in tumor progression. The factors regulating these interactions are not known. We have used co-immunoprecipitation and co-clustering paradigms to show(More)
AIM This paper is a report of a study to explore the experiences of older people who suffered a recent fall and identify possible factors that could contribute to service development. BACKGROUND Falls in older people are prevalent and are associated with morbidity, hospitalization and mortality, personal costs to individuals and financial costs to health(More)
The term "Sjögren's syndrome" (SS) is frequently used to describe the occurrence of keratoconjunctivis sicca and xerostomia in association with an autoimmune disorder. However, well-defined criteria for the classification of SS have not been established, and this diagnosis is being applied to a wide spectrum of conditions, ranging from clear "autoimmune"(More)
The clinical use of anti-oestrogens in breast cancer therapy has traditionally been restricted to tumours that contain measurable oestrogen receptor protein. However, it is now widely recognised that the clinical response to adjuvant anti-oestrogen therapy appears to be independent of the oestrogen receptor content of the primary tumour. The study reported(More)
In this study, we show that the neurite outgrowth response stimulated by N-cadherin is inhibited by a recently developed and highly specific fibroblast growth factor receptor (FGFR) antagonist. To test whether the N-cadherin response also requires FGF function, we developed peptide mimetics of the receptor binding sites on FGFs. Most mimetics inhibit the(More)
Recent experimental work has identified a novel intracellular binding site for the synthetic progestin, Gestodene, that appears to be uniquely expressed in human breast cancer cells. Gestodene is shown here to inhibit the growth of human breast cancer cells in a dose-dependent fashion, but has no effect on endocrine-responsive human endometrial cancer(More)
