An apoptotic signal leads to increased binding of p150 to the c-MYC promoter.

(A) Left - Etoposide-treated HOSE cells were monitored for apoptosis by caspase-3 activation. Middle - Quantitative RT-PCR shows a moderate increase in SALL2 and a large decrease in c-MYC expression following etoposide treatment. Right - ChIP followed by qRT-PCR shows increased binding of p150 to the c-MYC promoter in etoposide-treated cells. All histograms are based on triplicate determinations. ** denotes p<0.01 comparing means of experimental and control.
