Studying the signaling pathways that promote invasion and metastasis in lung cancer is currently the focus of Dr. Fred Mortazavi's research. For example, as part of the adherens junction, p120-catenin (p120ctn) plays an important role in the stability of cell-cell adhesions and downregulation of the p120-catenin is reported in a large proportion (60-80 percent) of non-small cell lung cancer (NSCLC) cases. Mortazavi and others reported that p120-catenin is transcriptionally downregulated in NSCLC and identified two signaling pathways that mediate p120-catenin repression. Identifying the prometastatic signaling events in cancer cells could pave the way for the future interventions in order to stop the metastatic process.
