Breaking the Oncostatin M feed-forward loop to suppress metastasis and therapy failure

ABSTRACT

Deciphering the complex milieu that makes up the tumor microenvironment (TME) and the signaling engaged by TME cytokines continues to provide novel targets for therapeutic intervention. The IL-6 family member Oncostatin M (OSM) has recently emerged as a potent driver of tumorigenesis, metastasis and therapy failure, molecular programs most frequently attributed to IL-6 itself. In a recent issue of The Journal of Pathology, Kucia-Tran et al. describe how elevated Oncostatin M receptor (OSMR) expression results in a feed-forward loop involving the de novo production of both OSM and OSMR to facilitate aggressive properties in squamous cell carcinoma (SCC). Here, we discuss how new findings implicating OSM in conferring aggressive cancer cell properties can be leveraged to suppress metastatic outgrowth and therapy failure in SCC as well as other cancers.
