Molecular characeteristics of ovarian and prostate cancer

Dr. Mes-Masson has a longstanding interest in fundamental, translational and clinical research in ovarian and prostate cancers. Dr. Mes-Masson has invested considerable efforts into the establishement of extensive ovarian and prostate tissue repositories (including fresh frozen specimens from normal, benign and tumor tissues, and paraffin embedded samples). She has developed several ovarian cancer models, including primary cultures from clinical material, spontaneously immortalized unique ovarian cancer cell lines as well as 3D spheroids and mouse xenografts that have been used in research studies. Dr. Mes-Masson’s research interests focus on the molecular features of ovarian and prostate cancers as an approach towards understanding the etiology and biology of these cancers. Prognostic and predictive biomarkers are studied at the gene and protein levels using the tissue repository and the derived cell line models. Using these resources Dr. Mes-Masson has identified genes modulated during the course of disease initiation and progression and have characterized biological parameters that are affected by the modulation of candidates using both in vitro and in vivo assays. Dr. Mes-Masson’s research is also directed towards the development of novel therapeutic strategies for ovarian and prostate cancer treatments.  Moreover, she has recently incorporated the microfluidics technology for empirical drug testing using 3D spheroids as well as ex-vivo micro-dissected tumors from mouse xenografts and patient samples.


Current projets (techniques used):

  1. Prognostic and predictive biomarker discovery using gene microarray, SNP array and deep sequencing. Biomarkers are validated at the protein level by immunohistochemistry or immunofluorescence on a tissue microarray platform.   

  2. Development of new treatment strategies for high-grade serous epithelial ovarian cancer (EOC) using poly-ADP ribose polymerase inhibitors in combination with other therapeutic drugs.

  3. Investigate the pivotal role of small GTPAse Ran at mitosis in cancer cells and establish the link between aneuploidy and Ran dependency using our unique panel of EOC cell lines, exhibiting complex karyotypes and diverse chemo-responses.

  4. Development of  new small molecules that inhibit Ran and evaluate their therapeutic value taking advantage of our in vitro and in vivo EOC models.

  5. Analysis of chemotherapy response using ex-vivo microdissected tumors (MDTs) cultured on microfluidics devices. MDTs are derived from xenograft models of our cell lines or from ovarian and prostate cancer patients. The value of this empirical testing is compared to predictive biomarkers on tissue microarrays.

  6. Effect of androgen receptor stimulation/inhibition and IKKe expression on cell motility, proliferation and survival (cell death, senescence, cell cycle arrest) of hormone-sensitive and castrate-resistant prostate cancer cells.
