STAT3 is highly expressed in both tumor and normal tissues, and STAT3 expression was expressed at a significantly higher concentration in non-neoplastic tissue samples compared to tumor tissue samples (mean log2 expression: 12.66; IQR: 12.4–12.7 vs. 11.91, IQR: 11.68–12; p = 0.0015) (Figure 4E). The gene discussed is STAT3; the disease is neoplasm.
