PLXNB2 and acute myeloid leukemia: Whole-genome and circRNA microarrays were conducted from 8 samples of AML patients with or without EMI and 4 samples of healthy controls, which indicating PLXNB2, hsa_circ_0004520 and hsa_circ_0001257 were likely to be involved in the regulation of intercellular crosstalk associated with EMI [21].
