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...

Quel est l'impact des interventions infirmières sur la gestion de l'incertitude et le vécu des hommes atteints d'un cancer de la prostate ? : travail de Bachelor

Dudouit, Noémie ; Dulac, Cynthia ; Bobbink, Paul (Dir.)

Mémoire de bachelor : Haute école de santé Genève, 2020.

L'objectif de cette revue de littérature, est d'identifier les interventions infirmières permettant de soutenir les hommes atteints du cancer de la prostate faisant face à de l'incertitude et de décrire leurs vécus face à celle-ci. Les bases de données Pubmed et Cinhal on été consultées entre le 3 décembre 2019 et le 14 février 2020. Parmi les huit études retenues, les devis...

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...

A novel prostate cell type-specific gene signature to interrogate prostate tumor differentiation status and monitor therapeutic response (running title: Phenotypic classification of prostate tumors)

Mapelli, Sarah N. ; Albino, Domenico ; Mello-Grand, Maurizia ; Shinde, Dheeraj ; Scimeca, Manuel ; Bonfiglio, Rita ; Bonanno, Elena ; Chiorino, Giovanna ; Garcia-Escudero, Ramon ; Catapano, Carlo V. ; Carbone, Giuseppina M.

In: Cancers, 2020, vol. 12, no. 1, p. 23 p

In this study, we extracted prostate cell-specific gene sets (metagenes) to define the epithelial differentiation status of prostate cancers and, using a deconvolution-based strategy, interrogated thousands of primary and metastatic tumors in public gene profiling datasets. We identified a subgroup of primary prostate tumors with low luminal epithelial enrichment (LumElow). LumElow tumors were...

Inhibition of Notch pathway arrests PTEN-deficient advanced prostate cancer by triggering p27-driven cellular senescence

Revandkar, Ajinkya ; Perciato, Maria Luna ; Toso, Alberto ; Alajati, Abdullah ; Chen, Jingjing ; Gerber, Hermeto ; Dimitrov, Mitko ; Rinaldi, Andrea ; Delaleu, Nicolas ; Pasquini, Emiliano ; D’Antuono, Rocco ; Pinton, Sandra ; Losa, Marco ; Gnetti, Letizia ; Arribas, Alberto ; Fraering, Patrick ; Bertoni, Francesco ; Nepveu, Alain ; Andrea Alimonti

In: Nature communications, 2016, vol. 7, p. 13719

Activation of NOTCH signalling is associated with advanced prostate cancer and treatment resistance in prostate cancer patients. However, the mechanism that drives NOTCH activation in prostate cancer remains still elusive. Moreover, preclinical evidence of the therapeutic efficacy of NOTCH inhibitors in prostate cancer is lacking. Here, we provide evidence that PTEN loss in prostate tumours ...
