  • Jan 2021; A novel mechanism of carcinogenesis. Our lab has identified a novel signaling pathway that helps human cells detect abnormal DNA structures called "chromatin bridges" that can lead to carcinogenesis. These findings, published in the Journal of Cell Biology, could lead to better understanding of the origins of the disease. 

  • Dec 2020; H.F.R.I. grant award. Dr Eleni Petsalaki has received a prestigious grant award of ~180,000 euros for three years from the Hellenic Foundation for Research and Innovation to investigate the molecular mechanisms by which human cells prevent chromatin bridges from breaking in cytokinesis.
