Research interests:

My interest is focused on the transmission electron microscopy of the nucleus, on the investigation of the ultrastructural dynamics of the nuclear chromatin detected in chemically fixed cells,  cryofixed cells, metaphase chromosomes. I’m interested in the apoptosis response to drug chemotherapy in human osteosarcoma cell lines, in AKT kinase and its converging signaling pathway induced by TRAIL cytokine in drug resistant cells.

More recently I’m focused on lamins in chromatin dynamics, cellular differentiation and some rare human diseases with defects of the nuclear envelope proteins, such as muscular dystrophies, lipodystrophies or systemic aging syndromes. I’m focused on the visualization of nuclear proteins by light immunofluorescence and on the analysis of  the modified nuclear phenotypes detected in these laminopathies, as well as phenotypes of the cell nucleus with exogenous expression of mutated Lamin A forms.  I’m focused on the interaction of Lamin A mutated forms with emerin,  their cell nucleus phenotypes  in the muscular laminopathy EDMD1 (Emery-Dreifuss Muscular Dystrophy),  and their involvement in the myogenic differentiation of C2C12 murine myoblasts.
