Research

Our goal is to understand the role of transcription factors acting at specific steps in the mammary lineage and to develop treatments based on targeting transcription in breast cancer cells. We classified breast cancer into three major groups (luminal, molecular apocrine and basal, Farmer et al., 2005), and recently developed an algorithm based on transcription factor expression to classify tumours into these groups (Iggo, 2018).

To target luminal tumours that are resistant to existing anti-estrogen therapies we are developing strategies based on selective androgen receptor modulators (SARMs, Hickey et al., 2020).

To target molecular apocrine tumours, we have performed two clinical trials with anti-androgens (NCT01842321 and NCT03383679) but we need to better understand the biology of these tumours.

To target basal and stem cell-like tumours (commonly referred to as TNBC in the clinical literature because they do not express the estrogen receptor ER, the progesterone receptor [PR] or ERBB2 [HER2]), we are exploring an embryonic isoform of RNA polymerase III as a potential target.

Notre objectif est de comprendre le rôle des facteurs de transcription agissant à des étapes spécifiques de la lignée mammaire et de développer des traitements basés sur le ciblage de la transcription dans les cellules du cancer du sein. Nous avons classé le cancer du sein en trois grands groupes (luminal, apocrine moléculaire et basal, Farmer et al., 2005), et avons récemment développé un algorithme basé sur l'expression des facteurs de transcription pour classer les tumeurs dans ces groupes (Iggo, 2018).

Pour cibler les tumeurs luminales qui sont résistantes aux thérapies anti-œstrogènes existantes, nous développons des stratégies basées sur les modulateurs sélectifs des récepteurs aux androgènes (SARMs, Hickey et al., 2020).

Pour cibler les tumeurs apocrines moléculaires, nous avons réalisé deux essais cliniques avec des anti-androgènes (NCT01842321 et NCT03383679) mais nous devons mieux comprendre la biologie de ces tumeurs.

Pour cibler les tumeurs basales et les tumeurs semblables aux cellules souches (communément appelées TNBC dans la littérature clinique car elles n'expriment pas le recepteur d'éstrogène [ER], le récepteur de la progestérone [PR] ou ERBB2 [HER2]), nous explorons une isoforme embryonnaire de l'ARN polymérase III comme cible potentielle.
