“…AVP has been suggested to have a physiological role in the myometrium as it can induce uterine contractions [78], and similar with OTR regulation, there are some studies that suggest increase in the density of V1aR during the later weeks of gestation and in preterm labour tissues [79,80]. Therefore it may be hypothesized that OTR/V 1a R or OTR/V 2 R dimers have a functional role in the onset of labour.…”

“…A review of our previous work indicated that atosiban, an OTR antagonist that is currently used in the treatment of preterm labor because of its ability to block the G q /PLC/calcium signaling pathway in myometrial cells (12)(13)(14)(15), inhibits the proliferation of some cancer cells (16 Cell Culture-The human prostate carcinoma DU145 cell line was purchased from ATCC (Manassas, VA) and routinely cultured in RPMI 1640 medium (Invitrogen), supplemented with 10% fetal calf serum (Invitrogen), penicillin-streptomycin (Invitrogen), and Fungizone (Invitrogen), in a 5% CO 2 humidified atmosphere, at 37°C. Production, pharmacological characterization, and culture conditions of MDCK and HEK293 clones stably expressing the human OTR cDNA fused to EGFP have been described elsewhere (11,19).…”

“…Esses eventos foram possíveis de serem descritos após a clonagem de receptor humano de ocitocina, porém os mecanismos sinalizadores que são mediadores dos efeitos da ocitocina no hipotálamo, hipófise e útero ainda não são conhecidos 10 . No útero, a ocitocina apresenta duas funções, regular a atividade contrátil do miométrio e promover a produção de prostaglandinas pelas células endometriais/deciduais 11 . As prostaglandinas também desempenham um importante papel na atividade contrátil do miométrio.…”
