Abstract

To evaluate the mechanism underlying the communication between myeloid malignant and bone marrow (BM) microenvironment cells in disease progression, the current study established BM mesenchymal stromal cells (MSCs) and assessed extracellular vesicle (EV) microRNA (miR) expression in 22 patients with myelodysplastic syndrome (MDS) and 7 patients with acute myeloid leukemia and myelodysplasia‑related changes (AML/MRC). Patients with MDS were separated into two categories based on the revised International Prognostic Scoring System (IPSS‑R), and EV‑miR expression in BM‑MSCs was evaluated using a TaqMan low‑density array. The selected miRs were evaluated using reverse transcription‑quantitative PCR. The current study demonstrated that the expression of BM‑MSC‑derived EV‑miR was heterogenous and based on MDS severity, the expression of EV‑miR‑101 was lower in high‑risk group and patients with AML/MRC compared with the control and low‑risk groups. This reversibly correlated with BM blast percentage, with which the cellular miR‑101 from BM‑MSCs or serum EV‑miR‑101 expression exhibited no association. Database analyses indicated that miR‑101 negatively regulated cell proliferation and epigenetic gene expression. The downregulation of BM‑MSC‑derived EV‑miR‑101 may be associated with cell‑to‑cell communication and may accelerate the malignant process in MDS cells.
