Research in our lab is focusing on the mechanisms of Chromosomal Instability (CIN), which is a hallmark of human cancer and a key driving force for tumorigenesis, tumor progression and tumor evolution. CIN causes the perpetual generation and further evolvement of structural and numerical chromosome aberrations that directly contribute to phenotypic changes in tumor cells towards the development of aggressive and therapy-resistant forms of cancer. Thus, it is of utmost interest to understand how CIN is triggered and how CIN might be targeted through novel therapeutic concepts.
Our lab is particularly interested in the mechanisms of how numerical CIN, which is caused by errors during mitotic chromosome segregation, is generated in human cancer cells. For this, we are investigating the role of dynamic microtubules in mitosis, the assembly of the mitotic spindle, the links between DNA replication stress and mitotic dysfunction and the role of oncogenic and tumor suppressor pathways in mitotic regulation. Together, we aim to understand of how structural and numerical chromosome aberrations as driving forces for tumor evolution are generated in human cancer cells.
Holger Bastians is a Professor for Cellular Oncology at the University Medical Center Göttingen (UMG) and at the Göttingen Center for Molecular Biosciences (GZMB).
He studied Biology with a focus on molecular biology and genetics at the Universities in Bayreuth and Osnabrück.
He obtained his Ph.D. (summa cum laude) at the German Cancer Research Center (DKFZ) in Heidelberg in 1996, where is investigated the role of novel protein phosphatases in human cell cycle control.
In 1996, he moved to Boston, USA, to join the laboratory of Prof. Joan Ruderman at the Harvard Medical Center as a postdoctoral fellow. His work was focusing on the role and mechanisms of mitosis-specific protein proteolysis mediated by the anaphase promoting complex or cyclosome (APC/C) in human cells.
Following his postdoctoral work in the US, he became an independent group leader at the Institute of Molecular Tumor Research (IMT) at the Philipps-University in Marburg. With his own lab, he investigated the role of the mitotic spindle checkpoint and the mechanisms of chromosome missegregation in human cancer cells.
In 208, Holger Bastians was awarded with the prestigious DFG Heisenberg fellowship and in 2011, he became a Heisenberg Professor at the University Medical Center Göttingen. Since 2013 he is an appointed Professor for Cellular Oncology at the UMG and GZMB.
Based on his research work, Holger Bastians was awarded in 2015 with the Innovation Prize of the German Society for Cell Biology (DGZ).
Since 2019 he is the speaker of the DFG-funded research unit 2800 (FOR2800) “Chromosome Instability: cross-talk of DNA replication stress and mitotic dysfunction”. Additionally, he is heading research projects as part of the DFG-funded Clinical Research Unit 5002 (KFO5002, since 2020) and within the Collaborative Research Center 1324 (SFB1324, since 2017).

„Chromosome Instability: Cross-talk of DNA replication stress and mitotic dysfunction”.
Speaker: Holger Bastians
Our lab established and coordinates this nation-wide research consortium. In our FOR2800 sub-project (SP2) we are focusing on the molecular mechanisms of how DNA replication stress causes mitotic chromosome missegregation leading to the induction of chromosomal instability in human cancer cells.
