Auxin-inducible degradation of BLM increases sister chromatid exchange

Our Research Unit addresses an important question on the origin of chromosome instability (CIN), which causes structural as well as numerical chromosome aberrations. Importantly, CIN and increased levels of chromosome aberrations are closely associated with many human diseases including cancer, neurodegenerative diseases and age-related syndromes and can act as key drivers for disease development and progression. An important condition that causes structural chromosome instability (S-CIN) leading ...

Replication stress is a key driver of genomic instability giving rise to human disease, for instance cancer or developmental disorders. It is caused by a variety of defects such as lesions blocking replication (e.g. DNA interstrand crosslinks) or processes that lead to the exhaustion of DNA precursors. This generates under-replicated DNA and replication intermediates that can be rescued by repair processes requiring homologous recombination between sister chromatids. Often, cells exposed to ...
