Using the RNA-seq data of 100 leukemia/lymphoma cell lines, we screened the expression levels of TGFb-pathway members and detected strong activities of the TGFb-receptor gene TGFBR2 in BCP-ALL cell lines (Figure 6B), which may reflect the physiological significance of this pathway therein. This evidence concerns the gene TGFBR2 and acute lymphoblastic leukemia.
