The first work of Marcel Mersel dealt with the lipid biochemistry of cells and membranes (1). For this study, Marcel Mersel developed an experimental approach which makes it possible in vitro to simultaneously stain the proteins and lipids of the outer sheet of plasma membrane which are the most exposed to the extra-cellular environment (2, 3). This method resulted in the validation of other methods for targeting phospholipids of the outer membrane sheet (4, 5) and in the filing of a patent describing the radioactive staining of the hydrophobic component of gangliosides (6, 7). Marcel Mersel also developed an original method of purifying the plasma membranes of cells cultured in vitro (8-10). All those methods brought to light the fact that the enzymatic activity involved in the biosynthesis of specific phospholipides was modulated by blocking cell division through contact inhibition (11, 12).
Thanks to his expertise in the culture of rat cardiac cells, Professor Mersel demonstrated that 7ß-hydroxycholesterol (7b-OHCH), a molecule with anti-cancer potential, was not cytotoxic for that type of cell (13). Subsequently, the author demonstrated that the cytotoxicity of this molecule on fibroblast cultures of cardiac origin was correlated with a metabolite of the 7b-OHCH metabolite (14). On the basis of preliminary observations, he demonstrated in many publications and in a CNRS patent that metabolites have a very beneficial influence on the glioblastoma, a form of brain cancer which to date is still incurable (15, 16, 17, 18, 19, 20).
As for sterols, Marcel Mersel conducted research into another type of orphan disease: SBMA (Spinal Bulbar Myoatrophy), a genetic illness affecting the motoneurones at androgen receptors sites. By using innovative experimental approaches and developing a motoneuronal model that mimics SBMA, Marcel Mersel is in the process of shedding new light on this pathology (21, 22).
Marcel Mersel also contributed to other fields of research: the analysis of lipids in the chromatine, the cochlear NMDA receptors, the purification of nuclear IP 4 receptors and the study of spinal lesions (23-26 are cited as examples in the bibliography).
