The strand separation and nuclease activities associated with YB-1 are dispensable for cisplatin resistance but overexpression of YB-1 in MCF7 and MDA-MB-231 breast tumor cells generates several chemoresistance signatures.


YB-1 is a protein involved in DNA repair, transcription, splicing, translation, and confers cisplatin resistance in several cancers. However, it is unknown which YB-1 activity is required for this resistance. To identify the mechanism(s) by which nuclear YB-1 confers cisplatin resistance, we generated several YB-1 mutants and tested their impact on… (More)
