Figure 2.

AP‐1 gestational profile in rat myometrium. Representative Western blots and densitometric analysis of Jun (A) and fos proteins (B) from rat myometrium, cytoplasmic (left panel) and nuclear (right panel) fractions. Graphs represent mean of relative protein expression ±S.D., n = 4 sets. Cytoplasmic and nuclear proteins are normalized with ERK2 expression. ‘*’ and ‘**’ denotes statistical significance of TL versus marked gestational days (GD), where TL is compared with all other groups through Dunnett's multiple comparison test after one‐way anova (P values shown on graph). Representative pictures of immunohistochemistry of Jun (C) and fos proteins (D) from GD15 (early gestation), GD22 (TNIL, term not in labour) and GD23 (TL, term labour) of mouse myometrium. Areas of high magnification are shown as embedded pictures. IgG controls for all GDs are shown in C. Scale bar = 50 μm.
