Correlation between the alterations in the mRNA expressions of the α1-adrenoceptor and estrogen receptor subtypes in the pregnant human uterus and cervix

The roles of the α1-adrenergic receptor subtypes in rat embryonic implantation

“…Our theory was based on earlier experimental results of a heterologous regulation between E and adrenergic systems (16). In addition, we proved a strong correlation between the ERa and a 1B -AR mRNA expressions, in the pregnant human uterus, whereas other investigators found E cross-talk to the a 1B -AR in HEK-293-transfected cells (17,18).…”

The effects of female sexual hormones on α1- and α2- adrenergic receptor subtypes in the pregnant rat myometrium

“…The α 1 -AR agonists elicit contractions in the myometrium (Ducza et al 2002, Ducza et al 2005). All of the α 1 -AR subtypes are found in the early-pregnant rat uterus, with a predominance of the α 1A -ARs, while the α 1B -ARs were not detected in the late-pregnant (day 18-22) rat uterus (Ducza et al 2009).…”
