  Monocyte/Macrophage - like cell differentiation induced by TPA in HL60 cells leads to loss of Histone H4 Lysine 16 Acetylation
  Author(s): Rahul Kumar Vempati*
  
  12-O-Tetradecanoylphorbol-13-acetate (TPA) is a phorbol ester and induces monocyte/macrophage like cell differentiation in HL60 cells. The levels and patterns of gene expression differ greatly between differentiated and undifferentiated HL60 cells. Epigenetic histone modifications play a crucial role in transcriptional activation and alterations in the modification levels greatly affect the gene expression pattern. Acetylation of Histone H4 Lysine 16 (H4K16ac) is one such modification and has a significant role in transcriptional activation. Changes in its acetylation level either due to a physiological or pathological effect will have a dramatic effect on cellular gene expression. Here, a study was done to see the effect of TPA induced differentiation on H4K16ac levels in HL60 cells. Results obtained from flow cytometric analysis showed expression of macrophage cell surface marker CD.. View more»
