PLXNB2 and acute myeloid leukemia: In this study, our aims were to detect and analyse the expression of circPLXNB2 in AML patients presenting with or without EMI and healthy controls, to explore the correlation with the expression of the PLXNB2 gene, and to investigate the potential of circPLXNB2 as a new biomarker for the prognosis and treatment of AML.
