ChIP assay in the cyclin D1 regulation element. (A) OECM1 cells treated with EGF or LiCl, and SAS cells treated with AG1478 or Erbitux. (B, C) Quantification of proteins is described in "Materials and Methods" (B, OECM1 cells; C, SAS cells). (CT, control; H3K4me, H3K4 methylation; H3K9me, H3K9 methylation; H4ac, H4 acetylation).
