Abstract
Glioblastomas (GBM) are most common types of primary brain tumors and miRNAs play an important role in pathogenesis of glioblastomas. Here, we reported a new miRNA, miR-3154, which regulates glioblastoma proliferation and metastasis. miR-3154 was elevated in glioblastoma tissue and cell lines, and its elevation was associated with grade of glioblastomas. Knockdown of miR-3154 in cell lines weakened ability of proliferation and colony formation, and caused cell cycle arrested and higher percentage of apoptosis. Knockdown of miR-3154 also impaired ability of migration and invasion in glioblastoma cells. In mechanism, miR-3154 bound directly to Tumor Protein P53 Inducible Nuclear Protein 1 (TP53INP1), down-regulating TP53INP1 expression at both mRNA and protein level. Silence of TP53INP1 reversed the effect of miR-3154 knockdown on proliferation and metastasis of glioblastoma cells. These findings show that miR-3154 promotes glioblastoma proliferation and metastasis via targeting TP53INP1.
期刊介绍：
Cell Division is an open access, peer-reviewed journal that encompasses all the molecular aspects of cell cycle control and cancer, cell growth, proliferation, survival, differentiation, signalling, gene transcription, protein synthesis, genome integrity, chromosome stability, centrosome duplication, DNA damage and DNA repair.
Cell Division provides an online forum for the cell-cycle community that aims to publish articles on all exciting aspects of cell-cycle research and to bridge the gap between models of cell cycle regulation, development, and cancer biology. This forum is driven by specialized and timely research articles, reviews and commentaries focused on this fast moving field, providing an invaluable tool for cell-cycle biologists.
Cell Division publishes articles in areas which includes, but not limited to:
DNA replication, cell fate decisions, cell cycle & development
