The up-regulation of Y-box binding proteins (DNA binding protein A and Y-box binding protein-1) as prognostic markers of hepatocellular carcinoma.
PURPOSE The development of hepatocellular carcinoma is associated with the chronic inflammation of the liver caused by various factors such as hepatitis B or C virus infection. Previously, we reported DNA binding protein A (dbpA) as a candidate molecule that can accelerate inflammation-induced hepatocarcinogenesis. DbpA belongs to the Y-box binding protein family, and Y-box binding protein-1 (Y...
متن کاملInhibition of protein synthesis by Y box-binding protein 1 blocks oncogenic cell transformation.
The multifunctional Y box-binding protein 1 (YB-1) is transcriptionally repressed by the oncogenic phosphoinositide 3-kinase (PI3K) pathway (with P3K as an oncogenic homolog of the catalytic subunit) and, when reexpressed with the retroviral vector RCAS, interferes with P3K- and Akt-induced transformation of chicken embryo fibroblasts. Retrovirally expressed YB-1 binds to the cap of mRNAs and i...
متن کاملThrombin activates a Y box-binding protein (DNA-binding protein B) in endothelial cells.
Thrombin stimulates the expression of multiple genes in endothelial cells (ECs), but the trans-acting factors responsible for this induction remain undefined. We have previously described a thrombin-inducible nuclear factor (TINF), which binds to an element in the PDGF B promoter and is responsible for the thrombin inducibility of this gene. Inactive cytoplasmic TINF is rapidly activated and tr...
متن کاملY-box-binding protein-1 is a potential novel tumour marker for neuroblastoma.
BACKGROUND The Y-box-binding protein-1 (YB-1) is a member of a family of DNA-binding proteins and an oncogenic transcription factor that is highly expressed in cancers of the breast, lung and prostate. To date, no data are available on its role in neuroblastoma. The aim of the present study was to evaluate the YB-1 expression in neuroblastoma. MATERIALS AND METHODS A tumour tissue microarray ...
متن کاملThe role of nuclear Y-box binding protein 1 as a global marker in drug resistance.
Gene expression can be regulated by nuclear factors at the transcriptional level. Many such factors regulate MDR1 gene expression, but what are the sequence elements and transcription factors that control the basal and inducible expression of this gene? The general principles through which transcription factors participate in drug resistance are now beginning to be understood. Here, we review t...
