Y box-binding protein 1 induces resistance to oncogenic transformation by the phosphatidylinositol 3-kinase pathway.


Y box-binding protein 1 (YB-1) is a multifunctional protein that can act as a regulator of transcription and of translation. In chicken embryo fibroblasts transformed by the oncoproteins P3k (phosphatidylinositol 3-kinase) or Akt, YB-1 is transcriptionally down-regulated. Expression of YB-1 from a retroviral vector induces a strong cellular resistance to… (More)
