title: The tumor promoter tetradecanoyl-phorbol-acetate (TPA) elicits the redistribution of zinc in subcellular fractions of rabbit thymocytes measured by X-ray fluorescence.
abstract: Prolonged (90 minutes) incubation with tumor promoter 12-O-tetradecanoyl-phorbol-13-acetate (TPA) elicits the redistribution of zinc from the nuclear fraction and mitochondria to the cytosol and microsomes in rabbit thymocytes. The zinc redistribution might play a role in the TPA-caused desensitization of T lymphocytes towards calcium and in the TPA-induced inhibition of Gl----S phase transition and cytotoxicity of T lymphocytes.
