Abstract：
:The adenylate cyclase system of an established human trichilemmoma cell line was investigated. Stimulators of human epidermal adenylate cyclase system, epinephrine, histamine, adenosine, and prostaglandin E increased cyclic AMP levels of the trichilemmoma cells. The effects of epinephrine, histamine, and adenosine were inhibited by the addition of propranolol (a beta-adrenergic antagonist), cimetidine (histamine H2-antagonist), and theophylline (adenosine-receptor antagonist), respectively. The epinephrine, histamine, and prostaglandin E effects were augmented by the addition of cyclic AMP (cAMP) phosphodiesterase inhibitor, isobutylmethylxanthine (IBMX); the adenosine effect was augmented by another phosphodiesterase inhibitor, papaverine. Without the addition of these phosphodiesterase inhibitors, the maximal accumulations were observed at 3 min incubation. Following this, the cAMP content returned to the basal level, and the cells did not respond to repeated stimulations with the same initial stimulator. This fact indicates receptor-specific refractoriness. For example, epinephrine-pretreated cells did not respond to epinephrine, but retained their sensitivity to histamine. It has been known that normal epidermal keratinocytes are regulated in vitro by glucocorticoids, colchicine, and retinoids, resulting in the augmentation of their beta-adrenergic response. Only hydrocortisone treatment on the trichilemmoma cells resulted in the augmentation of the beta-adrenergic response. Although the established human trichilemmoma cell line has similar adenylate cyclase systems as normal epidermis, it apparently has lost some of the regulatory mechanism of the beta-adrenergic response.
