Epithelial GPS: Position of RNAi machinery is associated with epithelial identity

(Medical University of South Carolina) Researchers at the Medical University of South Carolina show in a new report that the RNA interference machinery, normally thought to reside in the nucleus or cytoplasm, predominantly localizes to these apical junctions and influences cell biology in the colon. Interestingly, in colon tumors, this localization is dysregulated and may shift the balance of RNAs to promote tumorigenesis.
