\u2666 Mechanisms of genome instability and three-dimensional nuclear organization of the mammalian genome<\/span><\/span><\/p>\n

Professor Mai’s research focuses on mechanisms of c-Myc-dependent locus-specific and karyotypic instability, c-Myc-dependent tumour development in vivo<\/i> and on understanding the three-dimensional (3D) nuclear organization of the mammalian genome in normal, immortalized and tumour cells.<\/span><\/p>\n

One of the major achievements of the c-Myc research line was the first demonstration that the deregulated expression of the proto-oncogene induces dynamic karyotypic alterations and mediates rearrangements, chromosomal and extrachromosomal amplification of specific genes. Using the mouse model of plasmacytoma the critical region of chromosome 11 involved in the promotion of accelerated plasmacytoma development was identified. Studying the three-dimensional (3D) nuclear organization of the mammalian genome, prof Mai demonstrated the existence of specific 3D signatures that are significantly different in normal, immortalized and tumor cell nuclei. In collaboration with Dr. Yuval Garini (then at Delft University of Technology, now at Bar Ilan University, Israel) a software [TeloViewTM<\/sup>] enabling  the measurements the 3D nuclear organization of telomeres was set up. Using <\/strong>TeloViewTM<\/sup> Hodgkin\u2019s patients were stratified into responding and non-responding groups. Ongoing studies focus on Hodgkin’s lymphoma, multiple myeloma, monoclonal gammopathies with unknown significance, myelodisplatic syndrome and acute myeloid leukemia, chronic lymphocytic leukemia, and various solid tumours. The current research is aimed to  introduce the 3D telomeric signatures as a clinical tool for cancer diagnosis, cancer cell detection, treatment decisions and monitoring. Recent studies done in collaboration with Dr. Angela Garcia (Queens University, Kingston) have described 3D nuclear telomeric profiles that specifically characterize patients with Alzheimer\u2019s diseases. Such profiles are different from 3D profiles found in age- and sex-matched healthy controls.<\/span><\/p>\n
