Properties of beta-adrenergic receptors in untreated and butyrate-treated Hela cells.

HeLa cells contain receptors on their surface which are beta-adrenergic in nature. The binding of (-)-[3H]dihydroalprenolol is rapid, reversible, stereospecific and of relatively high affinity. The HeLa cells also contain an adenylate cyclase which is activated by (-)-isoproterenol greater than (-)-epinephrine greater than (-)-norepinephrine. The adenylate… CONTINUE READING
