TGFB1 and chronic myelogenous leukemia, BCR-ABL1 positive: To demonstrate a role for TNFRSF4 in CML, we analyzed mRNA expression of TNFRSF4 and Treg-associated genes such as FOXP3 and TGFB1 in the BM of 66 newly diagnosed chronic phase CML patients and 73 healthy controls using a publicly available microarray data set (GSE13159; https://www.ncbi.nlm.nih.gov/geo/query/acc.cgi?acc=GSE13159).
