Expression of AP‐1 proteins in human term non‐labouring (TNIL) and labouring (TL) myometrium. Representative Western blots and densitometric analysis of Jun (A) and fos proteins (B) from human myometrium, cytoplasmic (left panel) and nuclear (right panel) fractions. Graphs represent mean of relative protein expression ±S.D., n = 6 samples. Cytoplasmic and nuclear proteins are normalized with ERK2 expression. ‘*’, ‘**’, and ‘***’ denotes statistical significance of TL versus TNIL, where TNIL versus TL groups were compared using unpaired t‐test (P values shown on graph). Representative pictures of immunohistochemistry of Jun (C) and fos proteins (D) from TNIL and TL of human myometrium. Areas of high magnification are shown as embedded pictures. IgG controls are shown in C. Scale bar = 50 μm.
