Abstract:Reduced expression of haploinsufficient tumour suppressor genes is sufficient to alter cellular phenotypes towards carcinogenesis without complete loss of gene expression. As an essential gene, complete expression loss of pre-mRNA processing factor 4 kinase (PRP4K, also known as PRPF4B) is lethal. However, we demonstrate here that reduction of PRP4K levels by small interfering RNA in the mammary epithelial cell lines HMLE and MCF10A can induce partial epithelial-to-mesenchymal transition (EMT) marked by the re… Show more
