A balanced gene complement is crucial for proper cell function. Aneuploidy, the condition of having an imbalanced chromosome set, alters the stoichiometry of gene copy numbers and protein complexes and has dramatic consequences at the cellular and organismal levels. In humans, aneuploidy is associated with different pathological conditions including miscarriages, aging, cancer, microcephaly and mental retardation. Our lab uses Drosophila to molecularly characterize the impact of aneuploidy at the cellular, tissue-wide and organismal levels. We have established an epithelial model of Chromosomal instability (CIN), a feature of most human epithelial tumors, to unravel a leading role of aneuploidy in the emergence of tumor-like behaviors like tissue invasiveness, senescence and malignancy. We are also interested in addressing the impact of aneuploidy in other tissue types and cells, including stem cells.
