No labour-associated or regional differences in NF-κB proteins in myometrium at term. Whole-cell tissue protein was extracted from matched upper and lower-segment myometrial biopsies collected before (L−) or after (L+) labour onset (example Western blots n=2 for each tissue type, bar graphs total n=4 for each tissue type). Western analysis was performed for IkBa (A; P= 0.9938 by ANOVA), p65 (B; P= 0.4177 by ANOVA), and Ser536-P-p65 (C; P= 0.4414 by ANOVA). Blots were scanned for densitometric analysis and values normalized against densitometry values for Gβ or GAPDH.
