The transformation suppressor gene, programmed cell death gene 4 (Pdcd4), inhibits tumor-promoter-mediated transformation of mouse keratinocytes and has been implicated as a tumor suppressor gene in the development of human cancer. The Pdcd4 protein interacts with translation initiation factors eIF4A and eIF4G and binds to RNA, suggesting that it might be(More)
The programmed cell death gene 4 (Pdcd4) gene has been implicated as a new tumor suppressor gene in the development of several types of human cancer. Pdcd4 interacts with the translation initiation factor, eIF4A, and is thought to act as a translation inhibitor. Here, we have used the chicken B-cell line DT40 to disrupt the Pdcd4 gene by homologous(More)
Porins are outermembrane beta-barrel proteins. They have varied biological functionality ranging from phage receptors, immunogenicity, pathogenicity to apoptosis. However, only a small number has been structurally and functionally characterised. A validation mechanism and a database of porins would be useful for target selection in proteomics and structural(More)
BACKGROUND Known breast cancer-predisposing genes account for fewer than 25% of all familial breast cancer cases and further studies are required to find the remaining high- and moderate-risk genes. We set-out to couple linkage analysis using microsatellite marker data and sequence analysis of linked regions in 13 non-BRCA1/2 families in order to find novel(More)
