ERβ binding sites in class I, II, and III genes. U2OS-ERβ cells were treated with or without doxycycline (Doxy) for 18 h and followed by vehicle or 10 nm E2 (doxycycline + E2) treatment for 1 h. ERβ binding sites near class I genes MSMB (A) and TMOD1 (B), class II genes CECR6 (C) and DHRS9 (D), and class III genes CST5 (E) and HAVCR2 (F) were plotted as the density of 26-bp tags mapping to the region. Figures were produced using the University of California, Santa Cruz genome browser.
