Northwestern Medicine research has unveiled critical insights into ovarian cancer stem cells and their chromatin structure. The study found that these stem cells possess a higher number of chromatin packing domains, granting them enhanced transcriptional flexibility under stress, like chemotherapy. While common cancer cells experience disrupted DNA processes, these stem cells uniquely activate genes responsible for DNA repair. This research adds a significant layer to our understanding of how chromatin organization in these cells contributes to their resilience and potential treatment resistance.
The study reveals that ovarian cancer stem cells possess increased chromatin packing domains, enhancing their ability to adapt gene expression in response to chemotherapy.
These cancer stem cells, considered the root of cancer, show significant resilience to treatment, prompting researchers to investigate their unique genetic characteristics.
