D. Relative quantities of RNA in the RNAchIP samples, detected by RT-qPCR with primers aligning on the intron1 of the Fosl1 gene as depicted in B (orange arrow). n=3 independent experiments. Data information: Histograms represent mean and s.d. Dots represent individual data points. P-values indicate significantly higher difference between IP in HP1γ and in KO cells (***P < 0.001; two-tailed Student's t-test).
