MAP3K7 and chronic myelogenous leukemia, BCR-ABL1 positive: In the present study, we found that the downregulation of UNC13B could in turn downregulate MAP3K7, CDK4, and PINK1 in K-562 cells; hence, UNC13B might directly or indirectly promote the biological activity of ATO-resistant CML cells by affecting the expression of the abovementioned proteins.
