TGFB1 and chronic myelogenous leukemia, BCR-ABL1 positive: In DLBCL and MM, a strong positive association was observed between TGFB1 expression and pro-tumor cytokines; whereas in MDS and CML, TGFB1 expression was positively correlated with tumor-suppressive components like NK and T cells and was negatively correlated with epithelial-to-mesenchymal transition (EMT) and tumor proliferation rate (Fig. 4A).
