Secretion by tumor cells of circulating bone-resorbing factors may frequently underlie the hypercalcemia that occurs in patients with malignancy. Efforts to identify the responsible mediators have been hampered by a lack of available human tumor cell systems suitable for study of the pathogenesis of the humoral hypercalcemia syndrome. We have established a transitionalcell carcinoma (TCC) line ...

Cytokines and hormones, including interleukin-1, tumor necrosis factor, growth hormone-releasing hormone, vasoactive intestinal polypeptide and prolactin, are involved in sleep regulation.
