LncRNA SNHG4 regulates miR-10a/PTEN to inhibit the proliferation of acute myeloid leukemia cells.

ABSTRACTObjectives: Long non-coding RNA (lncRNA) small nucleolar RNA host gene 4 (SNHG4) is a characterized oncogenic lncRNA in osteosarcoma. The analysis of the TCGA dataset suggested the downregulation of SNHG4 in acute myeloid leukemia (AML), indicating its possible involvement in this disease. Therefore, this study was performed to analyze the interaction between SNHG4 and miR-10a in AML.Methods: We included 60 patients with AML and 60 healthy participants. Transient transfections, luciferase activity assay, RT-qPCR, CCK-8, and Western blot were used to carry out the research.Results: In this study, we found that SNHG4 was downregulated in AML patients compared to healthy participants. SNHG4 and miR-10a can interact with each other. However, overexpression of SNHG4 and miR-10a failed to affect the expression of each other. Instead, SNHG4 overexpression led to upregulated PTEN, a downstream target of miR-10a. Cell proliferation analysis showed that SNHG4 and PTEN overexpression led to decreased proliferation rates of AML cells and attenuated the enhancing effects of miR-10a on cell proliferation.Conclusion: In conclusion, SNHG4 may regulate miR-10a/PTEN to inhibit the proliferation of AML cells.
