The effects of vitamin D on the protein expression of connexin 43 in immortalized human myometrial (UtSM) cells treated with interleukin 1β. The UtSM cells were treated with 100 nmol/L of vitamin D for 24 and 48 hours in the presence of interleukin 1β (10 ng/mL). The prepared cell lysates were subjected to Western blot analysis using anti-connexin 43. β-Actin was used as a loading control. The bars represent the mean ± SEM from 3 replicates in each group. Groups with asterisks (*P < .05) are significantly different from the vehicle-treated control or interleukin 1β. SEM indicates standard error of the mean; UtSM, myometrial smooth muscle.
