| Summary: | Objectives：MiR-140 and DNAJC3-AS1 have been proven to play critical roles in cancer biology, while their participations in acute myeloid leukemia (AML) are unclear. This study aimed to explore the role of miR-140 and DNAJC3-AS1 in AML.
Methods：Analysis of the expression of DNAJC3-AS1 and miR-140 was done with RT-qPCR. The role of DNAJC3-AS1 and miR-140 in the expression of each other was explored with overexpression assay. The direct interaction between DNAJC3-AS1 and miR-140 was analyzed with RNA pull-down assay. The subcellular location of DNAJC3-AS1 was explored with cellular subcellular fractionation assay. Cell proliferation analysis was done with BrdU assay.
Results：AML patients showed increased expression of DNAJC3-AS1 and decreased expression of miR-140. DNAJC3-AS1 was detected in both nuclear and cytoplasm samples, and a direct interaction between DNAJC3-AS1 and miR-140 was observed.
Discussion：Reduced expression of DNAJC3-AS1 was observed after miR-140 overexpression in AML cells. DNAJC3-AS1 increased cell proliferation and inhibited the role of miR-140 in suppressing cell proliferation.
Conclusion：In conclusion, miR-140 may target DNAJC3-AS1 to suppress cell proliferation in AML. |
