About Hannes Lans
Hannes Lans received his PhD from the Erasmus University, Rotterdam, The Netherlands, in 2005. In 2008, he received a Veni grant from NWO with which he set up C. elegans as in vivo model organism in the lab to study the DNA damage response. Currently, he is an associate professor at the Department of Molecular Genetics, Erasmus MC. His research focuses on the mechanism and regulation of Nucleotide Excision Repair (NER). This major DNA repair pathway removes many types of helix-distorting DNA lesions from the genome and is therefore essential to protect against cancer and aging.
Using mammalian and C. elegans cell biological and genetic tools, we aim to understand the mechanisms that control NER activity. We are particularly interested in the role that chromatin organization plays in regulating access and activity of NER proteins. Furthermore, we study how NER protects against disease, for which we focus on the impact of patient-derived mutations on NER functionality and organization of the DNA damage response in vivo, in the different cell types of multicellular organisms.

Mechanism and Regulation of Nucleotide Excision Repair
Nucleotide Excision Repair (NER) is a major DNA repair pathway that removes many divers helix-distorting lesions from DNA, such as those induced by UV-light and by several cancer therapeutics. We study how the mechanism and activity of NER is regulated within chromatin and in vivo, to understand how NER deficiency leads to disease and how this pathway can be exploited for cancer therapy. For our research, we use a range of cell biological, biochemical and genetic techniques and both mammalian cells as well as C. elegans as model systems.

About our research
Nucleotide Excision Repair
NER is a versatile DNA repair pathway that removes many DNA-helix distorting lesions, including those induced by UV light and several cancer drugs, and plays a central role in the UV-induced DNA damage response (DDR) of eukaryotic organisms. NER is a highly conserved multi-step process that is initiated by two DNA damage-sensing mechanisms:
(1) transcription-coupled NER (TC-NER), which recognizes lesions in the transcribed strand during
(2) global genome NER (GG-NER), which senses lesions located anywhere in the genome;
Both sub-pathways utilize the same machinery to unwind DNA, excise the damage and synthesize new DNA. NER studies provide a paradigm for understanding the impact of DNA damage on human health in relation to cancer and aging. The importance of NER in protecting against disease is illustrated by the severe cancer prone and/or developmental and progeroid symptoms observed in rare NER deficiency syndromes in humans.
We utilize both mammalian cell culture as well as C. elegans to understand how NER functions within a cell and within chromatin, to better understand how NER deficiency leads to disease. Also, we study how NER and other DNA repair pathways protects cells against cancer therapeutics like platinum drugs, to be able to increase therapy effectiveness and alleviate side effects.
For our research, we make use of many diverse genetic, cell biological and biochemical techniques, proteomics as well as confocal imaging, which we use to study the sub-nuclear spatio-temporal behavior of repair and chromatin remodeling proteins in response to damage.
