Oestrogen, an essential physiological regulator of reproductive function, controls lactotroph proliferation and prolactin release. The neuropeptide galanin co-localizes to the lactotroph, but its physiological function is largely unknown. Pituitary galanin expression is extremely sensitive to the oestrogen status of the animal. A marked elevation occurs(More)
The neuropeptides galanin and pituitary adenylate cyclase-activating peptide (PACAP) have been implicated in the physiological regulation of lactotroph function. Using the 235-1 clonal lactotroph rat cell line we have studied the signalling pathways mediating the secretory and mitogenic responses to galanin and PACAP. Both peptides stimulated prolactin(More)
Vasoactive intestinal peptide (VIP) and pituitary adenylate cyclase-activating peptide (PACAP) are hypothalamic peptides sharing considerable sequence homology which are postulated to be hypophysiotrophic releasing factors. When infused into man, PACAP has no effect on anterior pituitary hormone levels, while VIP causes a significant increase in circulating(More)
The Indium-labelled somatostatin analogue pentetreotide has been successfully developed for imaging of somatostatin receptor positive tumours. However there is significant renal tubular uptake of the radiolabelled peptide, which can obscure upper abdominal tumours and would preclude its use for targeted radiotherapy. The aim of this study was to determine(More)
This qualitative study investigated the attitudes, perceptions, and practices of breast cancer specialists with reference to the effect of patient age on management decisions in breast cancer, and attempted to identify national consensus on this issue. One hundred thirty-three relevant specialists, including 75 surgeons and 43 oncologists, participated in a(More)
Simultaneous measurements have been made of the actions of noradrenaline and other agonists, alone and in the presence of appropriate antagonists, on synaptic transmission and cyclic AMP levels in the rat olfactory cortex. The possible role of cyclic AMP as an obligatory mediator of the excitatory and inhibitory actions of noradrenaline is discussed.
