Therapeutic targeting of DCAF5 can reverse the malignant state of SMARCB1-mutant cancers.
Tiivistelmä
The content discusses the impact of DCAF5 on SMARCB1-mutant cancers, highlighting its role in stabilizing SWI/SNF complexes and reversing the cancer state.
- Loss of tumour suppressors like SMARCB1 poses challenges in cancer treatment.
- DCAF5 is crucial for the survival of SMARCB1-mutant cancers.
- DCAF5 promotes the degradation of incompletely assembled SWI/SNF complexes in the absence of SMARCB1.
- Depletion of DCAF5 leads to the reaccumulation of SMARCB1-deficient SWI/SNF complexes, reversing the cancer state.
- Therapeutic targeting of ubiquitin-mediated quality-control factors, like DCAF5, shows promise in treating cancers driven by disruption of tumour suppressor complexes.

"We contributed 14 SMARCB1-mutant cell lines to a near genome-wide CRISPR screen as part of the Cancer Dependency Map Project."
"DDB1–CUL4-associated factor 5 (DCAF5) is required for the survival of SMARCB1-mutant cancers."
"After depletion of DCAF5, SMARCB1-deficient SWI/SNF complexes reaccumulate, bind to target loci, and restore SWI/SNF-mediated gene expression."
