Equal amounts of total protein from whole cell lysates were blotted for either anti-ER-α-phosphoserine (α-pS118 and α-pS167) and anti-ER-α (α-ER-α) antibodies. T47D cells were grown in serum- and estrogen-deprived conditions and treated with vehicle (medium) (lane 1), 17β-estradiol (E) for 10 min (lane 2) and 30 min (lane 3), EGF for 10 min (lane 4) and 30 min (lane 5), or Eand EGF for 10 min (lane 6) and 30 min (lane 7). Equal amounts of total protein from whole cell lysates were blotted for either anti-ER-α-phosphoserine (α-pS118 and α-pS167) and anti-ER-α (α-ER-α) antibodies
