Change is in the air: the hypoxic induction of phenotype switching in melanoma

J Invest Dermatol. 2013 Oct;133(10):2316-2317. doi: 10.1038/jid.2013.208.

Abstract

Melanoma cells can switch from a highly proliferative, less invasive state to a highly invasive, less proliferative state, a phenomenon termed phenotype switching. This results in a highly heterogenous tumor, where a slow-growing, aggressive population of cells may resist tumor therapy, and it predicts tumor recurrence. Here we discuss the observation made by Widmer et al. that hypoxia may drive phenotype switching.
