    • Estradiol increases cAMP in the oviductal secretory cells through a nongenomic mechanism 
      Oróstica Arévalo, María Lorena; Lopez, John; Rojas, Israel; Rocco, Jocelyn; Diáz, Patricia; Reuqueń, Patricia; Cardenas, Hugo; Parada Bustamante, Alexis; Orihuela, Pedro A. (BioScientifica Ltd., 2014)
      In the rat oviduct, estradiol (E2) accelerates egg transport by a nongenomic action that requires previous conversion of E2 to methoxyestrogens via catechol-O-methyltranferase (COMT) and activation of estrogen receptor ...
    • Mating changes the subcellular distribution and the functionality of estrogen receptors in the rat oviduct 
      Orihuela, Pedro A.; Zuñiga, Lidia M.; Rios, Mariana; Parada-Bustamante, Alexis; Sierralta, Walter D.; Velásquez, Luis A.; Croxatto, Horacio B. (2009)
      Background: Mating changes the mode of action of 17beta-estradiol (E2) to accelerate oviductal egg transport from a nongenomic to a genomic mode, although in both pathways estrogen receptors (ER) are required. This change ...
    • Prolactin gene expression in the pituitary of rats subjected to vaginocervical stimulation requires Erk-1/2 ... 
      Reuquen, Patricia; Guajardo Correa, Emanuel; Oróstica Arévalo, María Lorena; Curotto, Constanza; Parada Bustamante, Alexis; Cárdenas Villarreal, Hugo; Orihuela, Pedro A. (Institute animal reproduction food research, 2017)
      Vaginocervical stimulation (VCS) induces twice-daily prolactin (PRL) surges resulting in pseudopregnancy in the rat. Furthermore, activation of the extracellular signal-regulated kinase-1/2 (Erk-1/2) is involved in the ...
    • The Role of Mating in Oviduct Biology 
      Parada Bustamante, Alexis; Oróstica Arévalo, María Lorena; Reuquén, Patricia; Zúñiga, Lidia M.; Cárdenas, Hugo; Orihuela, Pedro A. (Wiley, 2016)
      The oviduct connects the ovary to the uterus, and is subject to changes that influence gamete transport, fertilization, and early embryo development. The ovarian steroids estradiol and progesterone are largely responsible ...
