Circulating human lymphocytes possess specific and functional receptors for calcitriol and PTH. We sought to determine if they also possessed receptors for calcitonin (CT), the third classical calciotropic hormone. We isolated blood mononuclear cells from healthy volunteers to separate monocytes, total lymphocytes, and T-lymphocytes; the purity of the three(More)
Physical mapping of the human genome has until now been envisioned through single chromosome strategies. We demonstrate that by using large insert yeast artificial chromosomes (YACs) a whole genome approach becomes feasible. YACs (22,000) of 810 kb mean size (5 genome equivalents) have been fingerprinted to obtain individual patterns of restriction(More)
Rat astrocytoma C6 cells have been recently identified as target cells for ET-1, which stimulates inositol lipid turnover in these cells. It is shown here that binding of ET-1 to high-affinity receptors on C6 cells leads to 40-45% inhibition of isoproterenol-induced intracellular cyclic AMP accumulation, as well as to stimulation of inositol lipid turnover,(More)
Charcot-Marie-Tooth disease type 1A (CMT1A) is the most common inherited sensory and motor peripheral neuropathy. It is caused by PMP22 overexpression which leads to defects of peripheral myelination, loss of long axons, and progressive impairment then disability. There is no treatment available despite observations that monotherapeutic interventions slow(More)
Carbetimer is a new antineoplastic agent whose main side effects consist of neurotoxicity and long-term dose-dependent hypercalcemia. We previously showed that Carbetimer is a potent calcium chelator responsible for an acute decrease in ionized Ca levels observed in vivo. However, the mechanism of the progressive increase in serum Ca remains unknown. We(More)
The biological activity of 16-epoxy side-chain analogs of 1 alpha,25-dihydroxyvitamin D3, (1 alpha,25(OH)2D3) was evaluated in vitro and in vivo. Compared to 1 alpha,25(0H)2D3, all analogs had lower affinities for the pig duodenal vitamin D receptor and also for the human serum vitamin D binding protein. The in vitro effects on cell proliferation or(More)
