Abstract

As a malignant hematological cancer, acute myeloid leukemia (AML) influences the health of many people. This study explored the anti-AML activity of matrine (a natural-derived alkaloid), as well as the internal molecular mechanism. In vitro, cell viability, apoptosis, and productions of inflammatory cytokines including IL-1β, IL-6, and TNF-α were tested by MTT, Annexin V-FITC/PI staining, and ELISA, respectively. The expression levels of LINC01116 and miR-592 were measured by qRT-PCR. Bcl-2 and PCNA expression, and JAK/STAT3 pathway activity were evaluated by western blotting. Besides, an AML mouse xenograft model was established to further analyze the anti-AML activity of matrine. We found that matrine suppressed cell proliferation and levels of inflammatory factors, induced cell apoptosis, reduced LINC01116 expression, and raised miR-592 expression in AML cells. LINC01116 directly bound to miR-592 and downregulated its expression. Both LINC01116 overexpression and miR-592 knockdown attenuated the effects of matrine on AML cells. Moreover, miR-592 overexpression reversed the influences of LINC01116 overexpression on matrine-treated AML cells. Matrine inactivated the JAK/STAT3 pathway in AML cells via modulating LINC01116/miR-592. Additionally, matrine inhibited tumor growth via modulating LINC01116/miR-592 in vivo. To sum up, matrine exhibited the anti-AML activity through regulating the LINC01116/miR-592 axis, thereby inactivating the JAK/STAT3 pathway.
