‘Phenotype switching’ can make melanoma become metastatic, resistant to drugs

The findings were published in the journal Cancer Discovery and are currently available online. "We were able to demonstrate for the first time that different receptors within a single signaling pathway — in this case, the Wnt signaling pathway — can guide the phenotypic plasticity of tumor cells, and increased signaling of Wnt5A in particular can result in an increase in highly invasive tumor cells that are less sensitive to existing treatments for metastatic melanoma," said Ashani Weeraratna, Ph.D., assistant professor in the Tumor Microenvironment and Metastasis Program of Wistar’s NCI-designated Cancer Center, and senior corresponding author on the manuscript. …
