A) Representative Western blot showing IκBβ and IκBα in whole cell lysates from fetal PAEC pretreated with BAY-7085 (0–10 µmol/L, 1h) prior to LPS exposure (10 ng/mL, 1h). Calnexin is shown as a loading control.
B) Representative Western blot showing IκBβ and IκBα protein in whole cell lysate from fetal PAEC pretreated with parthenolide (0–2 µmol/L, 1h), DMSO vehicle, or control, and prior to LPS exposure (10 ng/mL, 1h). Calnexin is shown as a loading control.
