Figure 5: Effect of LHCGR pathway inhibition on human LHCGR promoter activity.
hLGCs were cultured for 24 h in serum-free media then transfected with the 174 bp human LHCGR proximal promoter region. Cells were left untreated (C) or were treated with hCG (50 ng/ml) or forskolin (5 μM) for 48 h in the presence or absence of H89 (H), U0126 (U), MK2206 (MK) or Mithramycin A (MTM). Paired columns differ significantly from each other by t-test (P < 0.05, n = 6).
