“…OT binds to a membrane receptor [32,33] and activates PLC [34,35] and PLA2 [22,35] to initiate an intracellular regulatory cascade that ultimately leads to the mobilization of arachidonic acid from membrane phospholipids. In many cell types, an increase in PLA2 activity is associated with an increase in PG synthesis [21].…”

“…Since OT activates PLC and PLA2 in the bovine endometrium [22], OT may be involved in the secretion of PGE2 as well as PGF2α from the endometrium. In the present study, we investigated the influence of OT on the secretions of PGE2 and PGF2α, as well as the basal secretions of these eicosanoids by the bovine endometrium during the estrous cycle.…”

“…ROBINSON et al 2001;MANN, LAMMING, et al 2006). Além disso, a ocitocina tem associação positiva com ativação de PLC e PLA2, e com a síntese de seus próprios receptores, portanto é considerado componente chave para a síntese de PGF2α endometrial (BURNS et al, 1997 , , BURNS et al, 1998BINELLI et al, 2000 Fonte: (OLIVEIRA, M. L., 2017) Legenda: A aplicação de 17β-estradiol em fêmeas bovinas no dia 15 após o estro promoveu: 1) Diminuição da abundância dos transcritos de receptores de estradiol (ESR1 e ESR2); 2) Aumento da expressão gênica de receptores endometriais de ocitocina (OXTR); 3) Diminuição da abundância de transcritos da proteína quinase C (PRKCα, PRKCβ) e de proteína (PKCα). 4) Diminuição da expressão gênica de PLA2G4 e 5) Diminuição da expressão gênica de PGF2α (AKR1B1 e AKR1C4).…”

“…Moreover, the synthesis of prostaglandins is associated with an increase in the activity of phospholipase (PL) A 2 in many cell types [16]. It has been suggested that two intracellular mechanisms, PLC and PLA 2 , mediate the stimulatory effect of OT on the release of PGF 2␣ from ovine [17] and bovine [18] endometrial tissues.…”
