Gata3 is suppressed by CNTF and rescues NET transcription. CNTF suppresses Gata3 mRNA in sympathetic neurons (A) and decreases Gata3 protein (B) in M17 cells. Gata3 levels were normalized to β-Actin levels and shown as a percent of control (mean values ± SEM, n=3). (C) A representative western blot showing Gata3 (top panel) and β-Actin (bottom) protein levels. (D) M17 cells were treated for 2 days with vehicle (Control) or CNTF. Cells were then transfected with NET-Luc+pRL-Null to monitor transcription, together with a control vector or Gata3 expression plasmid (Gata3 + CNTF) and maintained for two more days in CNTF or control medium. Data are a ratio of firefly luciferase/renilla luciferase. Data are mean values ± SEM of triplicate values. Each experiment was repeated at least 3 times. *p<0.05, **p<0.01, ***p<0.001.
