      Somatostatin analogues (SAs) are potential anticancer agents. This study was designed to investigate the expression of somatostatin receptors (SSTRs) in melanoma cells and the effect of two SAs on cell proliferation and ...
    • Immunohistochemical analysis of T-type calcium channels in acquired melanocytic nevi and melanoma 

      Maiques Carlos, Oscar; Macià Armengol, Anna; Moreno, Sara; Barceló Gómez, Carla; Santacana Espasa, Maria; Veà Jódar, Àlvar; Herreros Danés, Judit; Gatius Calderó, Sònia; Ortega Izquierdo, Maria Eugenia; Valls Marsal, Joan; Chen, Bo-Juen; Llovet Navàs, David; Matias-Guiu, Xavier; Cantí Nicolás, Carles; Martí Laborda, Rosa Ma. (Wiley Online Library, 2016-10-08)
      BACKGROUND AND OBJECTIVES: Cutaneous malignant melanoma arises from transformed melanocytes de novo or from congenital or acquired melanocytic nevi. We have recently reported that T-type Ca2+ channels (TTCs) are upregulated ...

    • Melanoma transplants in “green” mice: Fluorescent cells in tumors are not equivalent to host-derived cells 

      García-Olmo, Dolores C.; Picazo, María G.; García-Olmo, Damián (Elsevier, 2018)
      Background: To examine the usefulness of green fluorescent protein (GFP) mice for studying the interactions between normal cells and tumor cells in a host, we used a melanoma model in such “green” mice [C57BL/6-Tg(CAG-EGFP)1Osb ...
