miR-342-3p promotes osteogenic differentiation via targeting ATF3.
FEBS LETTERS(2018)
摘要
Through their multiple targets, microRNAs (miRNAs) are involved in numerous physiological and pathological processes. In this study, miR-342-3p was found to be deregulated with ossification of ligament or osteoporosis. We demonstrate that silencing miR-342-3p impairs osteoblast activity and matrix mineralization, while over expression of miR-342-3p promotes osteoblast differentiation significantly. Moreover, miR-342-3p directly targets activating transcription factor 3 (ATF3), which inhibits transcription of pro-osteogenic differentiation-associated genes. In addition, there exists a higher frequency of methylation at the CpG island of the Enah/Vasp-Like (EVL) locus in undifferentiated pre-osteoblasts; however, demethylation of the EVL CpG island induces over expression of miR-342-3p during osteogenic differentiation. This study suggests that miR-342-3p may serves as a potential marker for diagnosis and treatment of ossification of ligament and osteoporosis.
