    ..Taken together, our findings show how BARD1 promotes retention of the BRCA1/BARD1 complex at damaged DNA sites and suggest the use of HKMT inhibitors to leverage the application of PARP inhibitors to treat breast cancer. ..

    ..Taken together, the results suggest that the BRCA1-FANCJ and BRCA1-CtIP complexes are not downstream of the RNF8/RNF168/ubiquitin pathway, but are instead regulated by the HP1 pathway that precedes homologous recombination DNA repair. ..
