FZD1 and chronic myelogenous leukemia, BCR-ABL1 positive: In this study, when we look at doxorubicin-resistant K562 chronic myeloid leukemia cells, there was no significant change in expression of CTNNB1 gene encoding beta-catenin; as well as an increase of about 8-folds was observed in the gene encoding FZD1 from Wnt receptors.
