Loss and revival of androgen receptor signaling in advanced prostate cancer

Formaggio, Nicolò ; Rubin, Mark A. ; Theurillat, Jean-Philippe

In: Oncogene, 2021, vol. 40, no. 7, p. 1205–1216

Targeting the androgen receptor (AR) signaling axis has been, over decades, the mainstay of prostate cancer therapy. More potent inhibitors of androgen synthesis and antiandrogens have emerged and have been successfully i mplemented in clinical practice. That said, the stronger inhibition of the AR signaling axis has led in recent years to an increase of prostate cancers that de-differentiate...

TGFBI modulates tumour hypoxia and promotes breast cancer metastasis

Fico, Flavia ; Santamaria‐Martínez, Albert

In: Molecular Oncology, 2020, vol. 14, no. 12, p. 3198–3210

Breast cancer metastasis is a complex process that depends not only on intrinsic characteristics of metastatic stem cells, but also on the particular microenvironment that supports their growth and modulates the plasticity of the system. In search for microenvironmental factors supporting cancer stem cell (CSC) growth and tumour progression to metastasis, we here investigated the role of the...

Changes in breast cancer management during the Corona Virus Disease 19 pandemic : an international survey of the European Breast Cancer Research Association of Surgical Trialists (EUBREAST)

Gasparri, Maria Luisa ; Gentilini, Oreste Davide ; Lueftner, Diana ; Kuehn, Thorsten ; Kaidar-Person, Orit ; Poortmans, Philip

In: The breast, 2020, vol. 52, p. 110-115

Background: Corona Virus Disease 19 (COVID-19) had a worldwide negative impact on healthcare systems, which were not used to coping with such pandemic. Adaptation strategies prioritizing COVID-19 patients included triage of patients and reduction or re-allocation of other services. The aim of our survey was to provide a real time international snapshot of modifications of breast cancer...

Effects of anti-PD-1 immunotherapy on tumor regression: insights from a patient-derived xenograft model

Martín-Ruiz, Asunción ; Fiuza-Luces, Carmen ; Martínez-Martínez, Esther ; Arias, Clemente F. ; Gutiérrez, Lourdes ; Ramírez, Manuel ; Martín-Acosta, Paloma ; Coronado, Maria José ; Lucia, Alejandro ; Provencio, Mariano

In: Scientific Reports, 2020, vol. 10, no. 1, p. 7078

Immunotherapies, such as checkpoint blockade of programmed cell death protein-1 (PD-1), have resulted in unprecedented improvements in survival for patients with lung cancer. Nonetheless, not all patients benefit equally and many issues remain unresolved, including the mechanisms of action and the possible effector function of immune cells from non-lymphoid lineages. The purpose of this...

Magi1, a new potential tumor suppressor gene in estrogen receptor positive breast cancer

Alday-Parejo, Begoña ; Richard, François ; Wörthmüller, Janine ; Rau, Tilman ; Galván, José A. ; Desmedt, Christine ; Santamaria-Martinez, Albert ; Rüegg, Curzio

In: Cancers, 2020, vol. 12, no. 1, p. 223

Membrane-associated guanylate kinase (MAGUK) with inverted domain structure-1 (MAGI1) is an intracellular adaptor protein that stabilizes epithelial junctions consistent with a tumor suppressive function in several cancers of epithelial origin. Here we report, based on experimental results and human breast cancer (BC) patients’ gene expression data, that MAGI1 is highly expressed and acts...
