Both protein and gene expression of markers indicative of basophils (CCR3, CD123, FcεRI) and basophil activation (CD63, CD203c, tryptase) were measured (Figure 6), indicating that basophils are found in ovarian tumors and that they may be in an activated state, which could potentially impact tumor-progression and patient outcomes. The gene discussed is CD63; the disease is ovarian neoplasm.
