    • Effect of TNF-alpha on molecules related to the Iinsulin action in endometrial cells exposed to hyperandrogenic ... 
      Oróstica Arévalo, María Lorena; García, Paula; Vera, Carolina; García, Victor; Romero Osses, Carmen; Vega Blanco, María Margarita (Sage, 2018)
      Polycystic ovary syndrome (PCOS) affects not only ovarian functions but is also able to affect endometrium metabolism. Around 80% of women with PCOS are obese. High tumor necrosis factor (TNF)- production and low adiponectin ...
    • Endometria from Obese PCOS Women with Hyperinsulinemia Exhibit Altered Adiponectin Signaling 
      García, V.; Oróstica Arévalo, María Lorena; Poblete, C.; Rosas, C.; Astorga, I.; Romero Osses, Carmen; Vega Blanco, María Margarita (Georg Thieme Verlag, 2015)
      Hyperandrogenemia, hyperinsulinemia, and obesity affect 60-70% of patients with Polycystic Ovarian Syndrome (PCOS), who exhibit an altered endometrial insulin signaling. The aim of the study was to evaluate whether ...
    • Estradiol increases IP3 by a nongenomic mechanism in the smooth muscle cells from the rat oviduct 
      Reuquén, Patricia; Oróstica Arévalo, María Lorena; Rojas, Israel; Díaz, Patricia; Parada Bustamante, Alexis; Orihuela, Pedro A. (Bioscientifica, 2015)
      Estradiol (E2) accelerates egg transport by a nongenomic action, requiring activation of estrogen receptor (ER) and successive cAMP and IP3 production in the rat oviduct. Furthermore, E2 increases IP3 production in primary ...
    • Mating Decreases Plasma Levels of TGF beta 1 and Regulates Myosalpinx Expression of TGF beta 1/TGFBR3 in the Rat 
      Oróstica Arévalo, María Lorena; López, John; Zúñiga, Lidia M.; Utz, Daniella; Díaz, Patricia; Reuquen, Patricia; Parada Bustamante, Alexis; Cárdenas, Hugo; Orihuela, Pedro A. (Wiley, 2014)
      Mating shuts down a 2-methoxyestradiol (2ME)-dependent, non-genomic activity that is responsible for accelerating egg transport in the rat oviduct. The aims of this work were to investigate the role of TGF1 in this 2ME-reduced ...
    • 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 ...
    • A non-genomic signaling pathway shut down by mating changes the estradiol-induced gene expression profile ... 
      Parada Bustamante, Alexis; Orihuela, Pedro A.; Ríos, Mariana; Cuevas, Catherina A.; Oróstica Arévalo, María Lorena; Velásquez, Luis A.; Villalón, Manuel J.; Croxatto, Horacio B. (Society for Reproduction and Fertility, 2010)
      Estradiol (E2) accelerates oviductal egg transport through intraoviductal non-genomic pathways in unmated rats and through genomic pathways in mated rats. This shift in pathways has been designated as intracellular path ...
