miR-152 target sequence

It is the target sequence of miR-152, a modularized DNA part from a set of chemically synthetic oligo DNA library.

Usage and Biology

MiRNA locker assembled by using this modularized DNA part was able to bind miR-152 in an Ago2 dependent manner, that is, knockdown of miR-152 was achieved by transfecting cells with miRNA locker.

Dre-miR-152 is a novel miRNA founded in zebrafish.¹

It was found that miR-152 was underexpressed in human osteosarcoma (OS) tissues and cell lines. Decreased miR-152 was inversely correlated with lymph-node metastasis and advanced clinical stage. Overexpression of miR-152 significantly inhibited cell proliferation, colony formation, migration and invasion of OS cells. Bioinformatics analyses showed that miR-152 directly targeted E2F transcription factor 3 (E2F3), as further confirmed by a dual-luciferase reporter assay. Dre-miR-152 may be a therapeutic target for OS.²

Moreover, MiR-152 regulated cell proliferation and apoptosis of glioma mediated by Runx2, while the mechanism of down regulated miR-152 in glioma tissues and cells was its hypermethylation.³
