BACKGROUND: FAM230B serves as an oncogenic lncRNA in both gastric cancer and papillary thyroid cancer, while its role in acute myeloid leukemia (AML) is unclear. We predicted that FAM230B could be a target of miR-140, a well-characterized tumor suppressor, and analyzed their interaction in AML.
METHODS: Differential expressions of FAM230B and miR-140 in bone marrow mononuclear cells (BMMNCs) were determined by RT-qPCR. Correlations were analyzed by Pearson's correlation coefficient. Subcellular FAM230B location was determined using cellular fractionation assay. The direct interaction between FAM230B and miR-140 was confirmed by RNA pull-down assay. The roles of FAM230B and miR-140 in cell proliferation were explored using BrdU assay.
RESULTS: High FAM230B expression level and low miR-140 expression level were observed in AML. FAM230B and miR-140 were inversely correlated and directly interacted with each other. FAM230B could be detected in both cytoplasm and nuclear samples. MiR-140 overexpression downregulated FAM230B expression and suppressed the enhancing effects of FAM230B overexpression on cell proliferation.
CONCLUSION: MiR-140 may target FAM230B to suppress cell proliferation in AML.
