    • 2-hydroxyoestradiol and 2-methoxyoestradiol, two endogenous oestradiol metabolites, induce DNA fragmentation ... 
      Valencia Mandiola, Camila; Molina, C.; Florez, M.; Buñay, J.; Moreno, R. D.; Orihuela, P. A.; Castro Lara, Ariel; Parada Bustamante, Alexis (Blackwell, 2016)
      Elevated intratesticular levels of hydroxyoestradiols and methoxyoestradiols, two classes of endogenous oestradiol metabolites, have been associated with male infertility. The aim of this study was to explore the effects ...
    • Differential participation of endothelin receptors in estradiol-induced oviductal egg transport acceleration ... 
      Parada Bustamante, Alexis; Croxatto, Horacio B.; Cárdenas, Hugo; Orihuela, Pedro A. (Elsevier, 2012)
    • Greater prevalence of Y chromosome Q1a3a haplogroup in Y-microdeleted Chilean men: a case–control study 
      Lardone, M. C.; Marengo, Altinay; Parada Bustamante, Alexis; Cifuentes Ovalle, Lucía; Piottante, Antonio; Ebensperger, Mauricio; Valdebenito Sepúlveda, Raúl; Castro, Andrea (SPRINGER/PLENUM PUBLISHERS, 2013-02-08)
      To determine the prevalence of South Amerindian Y chromosome in Chilean patients with spermatogenic failure and their association with classical and/or AZFc-partial Y chromosome deletions. We studied 400 men, 218 with ...
    • Hydroxyestradiols and methoxyestradiols as endogenous factors associated to physiological and physiopathological ... 
      Parada Bustamante, Alexis; Orihuela, Pedro A.; Molina, Cristián; Cárdenas, Hugo; Reuquén, Patricia; Valencia, Cecilia; Rincón, Ramiro (Nova Science Publishers, 2013)
      Estradiol (E2) is a steroidal hormone generated by the conversion of testosterone via the p450 aromatase enzymatic complex. The E2 physiological actions are mainly mediated by its interaction with intracellular receptors ...
    • In Vitro maturation of fully grown mouse antral follicles in the presence of 1 nM 2-Hydroxyestradiol improves ... 
      Merico, Valeria; Zanoni, Mario; Parada Bustamante, Alexis; Garagna, Silvia; Zuccotti, Maurizio (Springer, 2020)
      Cathecolestrogens are estradiol metabolites produced during folliculogenesis in the mammalian ovary. 2-Hydroxyestradiol (2-OHE2) is one of the most abundant although its role remains unknown. The aim of this study is to ...
    • Mating effects on female reproductive organs: the paradigm of estrogen signaling pathways in the oviduct 
      Orihuela, Pedro A.; Cárdenas, Hugo; Tapia Pizarro, Alejandro; Oróstica Arévalo, María Lorena; Parada Bustamante, Alexis; Reuquén, Patricia (Nova Science Publishers, 2013)
      Mating induces several physiological changes in the female reproductive tract independently of oocyte fertilization, which are potentially required for a successful pregnancy. These effects include modifications in the ...
    • 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 ...
    • Role of 2-methoxyestradiol, an Endogenous Estrogen Metabolite, in Health and Disease 
      Parada Bustamante, Alexis; Valencia, Cecilia; Reuquén, Patricia; Díaz, Patricia; Rincón Rodríquez, Ramiro; Orihuela, Pedro A. (Bentham Science, 2015)
      Estradiol (E-2) is a steroid hormone whose physiological actions are mainly mediated by its interaction with intracellular estrogen receptors (ER) leading to modification on the mRNA and protein synthesis in its target ...
    • Spermatogenesis at the Extreme: Oxidative Stress as a Converging Mechanism of Testicular Damage Due to ... 
      Moreno, Ricardo D.; Reyes, Juan G.; Parada Bustamante, Alexis; Farías, Jorge G.; Aguirre, Verónica; Zepeda, Andrea B.; Figuero, Carolina A.; Pino Urtubia, José (Nova Science Publishers, 2012)
      Mammalian spermatogenesis is a complex physiological process that takes place inside seminiferous tubules in the testis. This process involves a fine balance between cell proliferation, differentiation and apoptosis, ending ...
    • Testis development in the absence of SRY: chromosomal rearrangements at SOX9 and SOX3 
      Vetro, Annalisa; Dehghani, Mohammad Reza; Kraoua, Lilia; Giorda, Roberto; Beri, Silvana; Cardarelli, Laura; Merico, Maurizio; Manolakos, Emmanouil; Parada Bustamante, Alexis; Castro, Andrea; Radi, Orietta; Camerino, Giovanna; Brusco, Alfredo; Sabaghian, Marjan; Sofocleous, Crystalena; Forzano, Francesca; Palumbo, Pietro; Palumbo, Orazio; Calvano, Savino; Zelante, Leopoldo; Grammatico, Paola; Giglio, Sabrina; Basly, Mohamed; Chaabouni, Myriam; Carella, Massimo; Russo, Gianni; Bonaglia, Maria Clara; Zuffardi, Orsetta (Nature Publishing, 2015)

    • 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 ...
