Segregation of chromosomes in mitosis and regulation of mitotic exit

During mitosis and meiosis, the duplicated genetic information, the chromosomes, are separated by a precise machine, which is called the mitotic or meiotic spindle, to opposite spindle poles. After the subsequent cell division, each daughter cell has an identical chromosome set. Defects in this machine can lead to cancer or Down-Syndrom. Our work aims to understand how this machine works and is regulated. For this, we purify the protein components of the mitotic spindle and analyze their properties in the test tube. Using the new tools of genome editing (CRISPR-Cas9), we manipulate genes that code for mitotic spindle components in human tissue culture cells and monitor the defects by microscopy. In collaboration with chemists and structural biologists, we develop drugs that impair this machine specifically in dividing cancer cells.
