Cluster analysis of ERα, ERβ, PRAB, PRB target genes in HEC1A and RL95-2 cells after E2 or P4 treatment. Target genes revealed from ChIP-qPCR experiment were clustered with Cluster 3.0 program and visualized using Java TreeView software. A. HEC1A cell line. E2+ERα: 101 ERα target genes after E2 treatment; E2+ERβ: 96 ERβ target genes after E2 treatment; P4+PRAB: 7 PRAB target genes after P4 treatment; and P4+PRB: 2 PRB target genes after P4 treatment. B. RL95-2 cell line. E2+ERα: 17 ERα target genes after E2 treatment; E2+ERβ: 24. ERβ target genes after E2 treatment; P4+PRAB: 52 PRAB target genes after P4 treatment; and P4+PRB: 40 PRB target genes after P4 treatment.
