Histone phosphorylation during differentiation of HL-60 cells induced by phorbol diesters

Thesis/Dissertation ·
OSTI ID:6945333

Phorbol ester effects on histone phosphorylation during induction of differentiation were examined in quiescent HL-60 cells. Following exposure to TPA, differentiation was determined by adherent properties, morphological maturity, and nonspecific esterase (NSE) activity. Changes in histone phosphorylation were concurrently investigated in the presence of /sup 32/P-phosphoric acid and histones fractionated using two-dimensional gel electrophoresis. Addition of TPA produced changes in H2B phosphorylation which were observable as early as 30 minutes, peaked at 4 hours, then slowly decreased to control levels.
