    • 27-hydroxycholesterol and the expression of three estrogen-sensitive proteins in MCF7 cells 
      Cruz, Pamela; Epuñán, María José; Ramírez, María Eugenia; Torres, Cristian G.; Valladares Boasi, Luis; Sierralta, Walter D. (2012)
      The principal aim of this study was to analyze in estrogen receptor-positive MCF7 cells the response of three estrogen-dependent proteins to 27-hydroxycholesterol (27OHC), a major circulating cholesterol metabolite. ...
    • A cyclic peptide derived from α-fetoprotein inhibits the proliferative effects of the epidermal growth ... 
      Torres, Cristian; Antileo, Elmer; Epuñán, María José; Pino Zúñiga, Ana María; Valladares Boasi, Luis; Sierralta Lundin, Walter (2008)
      A cyclic peptide derived from the active domain of α-fetoprotein (AFP) significantly inhibited the proliferation of MCF7 cells stimulated with the epidermal growth factor (EGF) or estradiol (E 2). The action of these three ...
    • Proliferation of human mammary cancer cells exposed to 27-hydroxycholesterol 
      Cruz, Pamela; Torres, Cristian; Ramírez, María Eugenia; Epuñán, María José; Valladares Boasi, Luis; Sierralta, Walter Daniel (2010)
      The aim of the present study was to identify the possible mechanisms by which certain estradiol receptor (ER)-positive mammary tumor cells remain resistant to treatment with anti-estrogens or inhibitors of local estradiol ...
