In fact, a recent study[69] demonstrated alterations of Hh pathway gene expression in a subpopulation of CML-CP patients: the negative modulators GLI3 and SUFU genes were down-regulated and the Hh target genes CCNB2, STIL, FOXM1 and GLI1 genes were up-regulated. Here, CCNB2 is linked to chronic myelogenous leukemia, BCR-ABL1 positive.
