| Research Abstract |
The targeting of Dlx5 and Msx2 mRNA by miR-124a and miR-181a is a key mechanism for negatively regulating these factors in order to suppress osteoblastic differen- tiation in non-osseous cells.Transfection of anti-miR-124a and anti-miR-181a did not induce osteoblastic differentiation in mouse iPS cells, suggesting that suppression of miR-124a and miR181a, which directly target Dlx5 and Msx2, is not sufficient to induce osteoblastic differentiation of mouse iPS cells, but that suppression of at least one miRNA of miR-10a, miR-10b, miR-9-3p and miR- 19b besides miR-124a and miR-181a is required for osteoblastic differentiation. MiR-10a, miR-10b, miR-19b and miR-9-3p may constitute a control mechanism for Dlx5 and Msx2.We found 6 miRNAs that were strongly associated and played a key role in controlling BMP-4-induced osteoblast differentiation in mouse iPS cells by suppressing the translation of their targeting genes.We also showed the possiblity of osteoblastic differentiation by anti-miRNA.
