The effect of basal hypothalamic deafferentation on the nycthemeral rhythm of plasma TSH.

abstract：:Treatment of isolated rat adipocytes with epinephrine or isoproterenol caused a time- and concentration-dependent increase in phospholipid methyltransferase (PLMT) activity that was blocked by propranolol and unaffected by phentolamine. Forskolin mimicked the stimulatory effect on PLMT, and insulin inhibited this effe...
