The distribution and expression levels of inflammatory and fibrotic mediators and RAGE signaling were evaluated through immunohistochemistry (NOX4, CML, RAGE, nuclear NF-κB, TNF-α, IL-1β, TGF-β1, SMAD2/3, CTGF, and a-SMA) and immunolocalization of CML/RAGE. The gene discussed is TGFB1; the disease is chronic myelogenous leukemia, BCR-ABL1 positive.
