    • In vitro net progesterone production by human corpora lutea: Effects of human chorionic gonadotropin, ... 
      Vega Blanco, María Margarita; Devoto, Luigi; Navarro, Veronica; Castro, Olga; Kohen Skop, Paulina (1987)
      Slices of human corpora lutea (CL) obtained at varying stages of the luteal phase from 21 women were used to study the effect of hCG on progesterone (P4) production. Slices obtained from mid- and late CL incubated with 10 ...
    • Luteal leukocytes are modulators of the steroidogenic process of human mid-luteal cells 
      Castro, Andrea; Castro, Olga; Troncoso, José Luis; Kohen Skop, Paulina; Simon, Carlos; Vega Blanco, María Margarita; Devoto, Luigi (Oxford University Press, 1998)
      Flow cytometry analysis of luteal cells revealed that an important proportion of these cells are leukocytes. The percentage of leukocytes was higher in the early (42 ± 4) and late (35 ± 3) luteal phases than in the mid-luteal ...
    • Progesterone synthesis by human luteal cells: Modulation by estradiol 
      Vega Blanco, María Margarita; Devoto, Luigi; Castro, Olga; Kohen Skop, Paulina (1994)
      To assess the role of estradiol (E2) upon progesterone (P4) synthesis, a well defined human midluteal cell system was used. A dose-dependent inhibition of P4 synthesis with and without hCG was induced by E2. In addition, ...

      Vega Blanco, María Margarita; Devoto, Luigi; Castro, Olga; Kohen Skop, Paulina (1994)
      To assess the role of estradiol (E2) upon progesterone (P4) synthesis, a well defined human midluteal cell system was used. A dose-dependent inhibition of P4 synthesis with and without hCG was induced by E2. In addition, ...
    • The steroidogenic response and corpus luteum expression of the steroidogenic acute regulatory protein after ... 
      Kohen Skop, Paulina; Castro, Olga; Palomino, Alberto; Muñoz, Alex; Christenson, Lane K.; Sierralta, Walter; Carvallo, Pilar; Strauss, Jerome F.; Devoto, Luigi (2003)
      This study was designed 1) to assess corpus luteum (CL) steroidogenesis in response to exogenous human chorionic gonadotropin (hCG) at different times during the luteal phase, 2) to examine the effect of hCG on steroidogenic ...
    • Tumor necrosis factor-α activates nuclear factor-κB but does not regulate progesterone production in cultured ... 
      González Navarrete, Flor Cecilia; Eisner, Verónica; Morales, Priscilla; Castro, Olga; Pommer Téllez, Ricardo; Quiroga, Clara; Lavandero González, Sergio; Devoto, Luigi (2007)
      Background. The role of tumor necrosis factor-α (TNF-α) in granulosa luteal cell function and steroidogenesis is still controversial. Our aim was to examine the steroidogenic response, together with the simultaneous ...
