Figure 2. Densitometric analysis of h-CaD and ERK2 expression in NIL and L myometrium.

Figure 2

Densitometric analysis was performed for 8×NIL and 8×L myometrial samples following immunodetection of phospho-h-CaD, total h-CaD, phospho-ERK 1/2, total ERK 1/2 and α-SMA. (A) Onset of labor was associated with a statistically significant, 2-fold up-regulation in h-CaD phosphorylation, whilst (B) total h-CaD expression remained unchanged. (C) ERK2 phosphorylation remained unchanged following the onset of labor, however (D) total ERK2 expression underwent a statistically significant 1.4-fold up-regulation in association with the onset of labor. *p<0.05, **p<0.02.
