Head and neck squamous cell carcinoma (HNSCC) accounts for high number of new diagnoses each year. Current management is based on surgery followed by radiotherapy or chemotherapy, where treatment-induced fibrosis is a common complication associated with therapy. Since fibrosis is mostly driven by dysregulation of the Rho-ROCK signaling axis, researchers from Australia have investigated the potential of modulating ROCK2 with the small-molecule inhibitor RX-10616 for its potential antifibrotic effect combined with radiotherapy in patient-derived murine models of HNSCC.
