IL-13/IL-13Rα2 axis promotes proliferation of angiosarcoma cells.

ABSTRACT: Angiosarcoma is a rare and aggressive soft tissue sarcoma with a poor prognosis and limited treatment options. The role of interleukin-13 (IL-13) and its receptors in angiosarcoma pathogenesis has been largely unknown. We first reanalyzed transcriptomic data from a published angiosarcoma cohort and found IL13RA2 mRNA elevated in angiosarcoma versus normal tissue. In addition, high IL13RA2 expression was significantly associated with increased nonsynonymous mutations. We next detected high IL-13 receptor α2 (IL-13Rα2) expression in angiosarcoma cell lines and patient samples compared to other cell types and benign vascular tumors. Moreover, histological analysis showed the presence of IL-13 in the angiosarcoma microenvironment. Functional studies using angiosarcoma cell lines, MO-LAS-B cell
