Tumor-related microRNA targeting PTEN / 国际肿瘤学杂志

MicroRNAs are the endogenous non-coding RNAs that regulate gene expression by mediating gene post-transcriptional silence.Among them,miR-21,miR-17-92,miR-214,miR-26a,miR-221,miR-222and so on mainly suppress the expression of PTEN phosphohydrolase through targeting PTEN mRNA 3'-UTR.PTEN plays an important role in cell proliferation,apoptosis,migration and invasion,and its low expression will induce tumorigenesis.
