The Epstein?Barr virus (EBV)-encoded latent membrane protein 1 (LMP1) oncogene
can induce profound effects on epithelial growth and differentiation including
many of the features of the epithelial-to-mesenchymal transition (EMT). To better
characterise these effects, we used the well-defined Madin Darby Canine Kidney
(MDCK) epithelial cell model and found that LMP1 expression in these cells
induces EMT as defined by characteristic morphological changes accompanied by
loss of E-cadherin, desmosomal cadherin and tight junction protein expression.
The induction of the EMT phenotype required a functional CTAR1 domain of LMP1 and
studies using pharmacological inhibitors revealed contributions from signalling
pathways commonly induced by integrin?ligand interactions: extracellular
signal-regulated kinases/mitogen-activated protein kinases (ERK-MAPK), PI3-Kinase
and tyrosine kinases, but not transforming growth factor beta (TGFβ). More
detailed analysis implicated the CTAR1-mediated induction of Slug and Twist in
LMP1-induced EMT. A key role for β1 integrin signalling in LMP1-mediated
ERK-MAPK and focal adhesion kianse (FAK) phosphorylation was observed, and
β1 integrin activation was found to enhance LMP1-induced cell viability and
survival. These findings support an important role for LMP1 in disease
pathogenesis through transcriptional reprogramming that enhances tumour cell
survival and leads to a more invasive, metastatic phenotype.
