Research Themes

The studies performed in the laboratory of Viral Oncology that I created in 1982 were aimed at understanding :
• the molecular basis for the Myeloblastosis Associated Virus (MAV) tumorigenic potential.
• the biochemical properties, mode of action and biological role of the CCN3 (NOV) protein in normal and pathological conditions with a particular emphasis to the potential use of the CCN3 protein as a new tool for molecular medicine
The MAV strains usually induce osteopetrosis, lymphomas, and nephroblastomas in chicken (Perbal, 1995). MAV is the natural helper virus of Avian Myelobalstosis virus (AMV). Molecular cloning of a MAV strain inducing specifically nephroblastoma when injected in day-old chicken (Perbal 1985, Soret et al. 1985) allowed to establish that MAV-induced nephroblastoma represent a unique animal model for the Wilms’ tumor (Perbal 1994). The molecular cloning of MAV integration sites in the host genome, identified several genes whose viral induced alteration is associated to cancer development (Li et al. 2006). One of them, CCN3 was one of the three founding members of the CCN family of 6 proteins involved in the regulation of cell proliferation and differentiation in several normal and tumoral contexts (Joliot et al., 1992, Perbal , 2001).
Functionally bipartite, with members acting negatively or positively on cell communication and signaling, the CCN proteins are subject to complex fine tuning regulation from which stemmed the concept of their biological properties being based on a spatio-temporal combinatorial events model (Perbal . 2013, 2018, 2023)
Disregulation of the ccn3 gene expression and abnormal production, processing or localization of the CCN3 protein is associated to malignancy in several tumor cases. CCN3 detection in tumor samples is associated to a favorable outcome in several types of tumors and in some documented cases its expression is associated to metastatic potentiality of the tumor cells (Planque and Perbal 2003, Perbal 2003). The value of CCN3 as a prognostic marker has been established in the case of osteosarcomas (Perbal et al. 2008) and melanomas (Vallacchi et al. 2008). CCN3 is reducing the tumorigenic potential of glioblastomas, choriocarcinomas, Ewing’s tumors and melanomas. These observations set the stage for developing protocols for genetic therapy of these tumors.
Proteins and ligands interacting with CCN3 allow it to play its regulatory role in the control of cell attachement, spreading, proliferation and differentiation. After biologically active truncated CCN3 proteins with different sub cellular localization (Perbal 2004, Planque et al. 2006), were identified in our laboratory, several groups reported the existence of truncated and rearranged forms of other CCN proteins (Perbal et al. 2023). Since the nuclear CCN3 proteins detected in cancer cells have been shown to regulate transcription, we have proposed that a balanced production of secreted CCN3 protein with anti-proliferative activity and nuclear CCN3 protein with pro-proliferative and oncogenic activities is required for the spatio temporal combinatorial events control of its biological activities (Perbal et al 2023).
Recent Orientations
My interest in the molecular basis of genetic diseases which stemmed from my early retrovirology studies, led me to undertake investigations in the legal aspects related to genetic information protection of human. Further to the COVID pandemic and interrogations expressed by the public, I became interested in social approches of medical diseases and the combination power of my scientific and legal activities culminated in my certification as a couple therapist and sexologist.
