    Trastuzumab treatment has significantly improved the prognosis of HER2-positive breast cancer patients. Despite this, resistance to therapy still remains the main clinical challenge. In order to evaluate the implication ...
  • mTOR inhibition and T-DM1 in HER2-positive breast cancer
    Casadevall Aguilar, David; Hernández Prat, Anna, 1984-; García-Alonso, Sara; Arpí Llucià, Oriol; Menéndez, Silvia; Qin, Mengjuan; Guardia Valenzuela, Cristina, 1990-; Morancho Armisen, Beatriz; Sánchez-Martín, Francisco Javier; Zazo, Sandra; Gavilán, Elena; Sabbaghi Mehrjardi, Mohammad Ali; Eroles, Pilar; Cejalvo, Juan M.; Lluch, Ana; Rojo, Federico; Pandiella, Atanasio; Rovira, Ana; Albanell Mestres, Joan (American Association for Cancer Research (AACR), 2022)
    In patients with trastuzumab-resistant HER2-positive breast cancer, the combination of everolimus (mTORC1 inhibitor) with trastuzumab failed to show a clinically significant benefit. However, the combination of mTOR ...
  • PP2A inhibition determines poor outcome and doxorubicin resistance in early breast cancer and its activation shows promising therapeutic effects.
