研究概览

Aim: Doxorubicin, pivotal for acute myeloid leukemia (AML) treatment, often succumbs to resistance, impeding therapeutic success. Conclusion: Our study reveals a novel mechanism of doxorubicin resistance mediated by exosomal miR-92b-5p and provides potential therapeutic targets for overcoming drug resistance in AML.

核心发现

Aim: Doxorubicin, pivotal for acute myeloid leukemia (AML) treatment, often succumbs to resistance, impeding therapeutic success.

Although exosomal transfer is linked to chemoresistance, the detailed role of exosomal miRNAs in doxorubicin resistance remains incompletely understood.

Methods: We employed miRNA sequencing to delineate the profile of exosomal miRNAs in doxorubicin-resistant K562/DOX cells and AML patients.

Subsequently, qPCR was utilized to scrutinize the expression of exosomal miR-92b-5p in these resistant cells and AML patients.
