NGS-based miRNome reveals regulation in the miR-34/miR-449 cluster targetome in sinonasal cancers [miRNA-seq]

Project description:Using NGS-based miRNome, followed by AGO2-RIP-seq, the miR-34c and miR-449a and their direct targets were identified as factors involved in the development and progression of sinonasal cancers (SNCs). Both miR-34c and miR-449a were independent prognostic biomarkers and were associated with patient outcome.

Transient transfection of miR-449 family in the hepatocellular carcinoma cell line HLE

Project description:In this study, we comparatively analyzed the members of the miR-449 family (miR-449a, miR-449b, and miR-449c) with regards to their target genes and functional effects in hepatocellular carcinoma (HCC). Microarray analysis after transient transfection of miR-449a, miR-449b, and/or miR-449c in the HCC cell line HLE identified putative target genes of miR-449a, miR-449b, and miR-449c. For transient overexpression of miRNAs, the HCC cell line HLE was transfected with 50 nM Allstars Negative Control or miScript miRNA mimics. MiRNA mimics for miR-449a, miR-449b, and miR-449c were either single transfected or cotransfected in equimolar amounts (16.7 nM each). Global mRNA expression profiling was performed utilizing pooled RNA of three biological replicates per microarray and two microarrays per condition.

Gene expression changes in the respiratory epithelium of miR-34/449 knockout mice

Project description:MicroRNA ablation prevents multiciliogenesis via cell cycle deregulation MicroRNAs (miRNAs) have been implicated in various biological processes but have been most frequently described to inhibit proliferation and tumorigenesis. Here we describe an essential function of the miR-34/449 family during differentiation of multiciliated cells that is mediated by their well-described suppression of cell cycle progression. Constitutive deletion of all six members of this miRNA family triggers a derepression of multiple cell cycle-promoting proteins, thereby preventing epithelial cells from exiting the cell cycle and to maintain in a quiescent state. As a result, formation of motile multicilia is strongly inhibited in several tissues including the respiratory epithelium and the fallopian tube. Consequently, mice lacking miR-34/449 genes display infertility as well as severe chronic airway disease leading to postnatal death. These results show how miRNA-mediated repression of the cell cycle is required to allow multiciliogenesis to proceed during epithelial differentiation.

The miR-28-5p targetome discovery identified SREBF2 as one of the mediators of the miR-28-5p tumor suppressor activity in prostate cancer cells

Project description:miR-28-5p is downregulated in some tumor tissues in which it has been demonstrated to have a tumor suppressor (TS) activity. Here, we demonstrate that miR-28-5p acts as a TS in prostate cancer (PCa) cells affecting cell proliferation/survival as well as migration and invasion. Using the miRNA pull out assay and next generation sequencing we collected the complete repertoire of miR-28-5p targets obtaining a data set (miR-28-5p targetome) of 191 mRNAs. Filtering the targetome with TargetScan 7, PITA and RNA22 we found that the 61% of the transcripts had miR-28-5p binding sites. To assign a functional value to the captured transcripts, we grouped the miR-28-5p targets into gene families with annotated function and showed that six transcripts belong to the transcription factor category. Among them we selected SREBF2, a gene with increasing importance in PCa. We validated miR-28-5p/SREBF2 interaction demonstrating that SREBF2 inhibition affects almost all the tumor processes affected by the miR-28-5p re-expression, suggesting that SREBF2 is an important mediator of miR-28-5p TS activity. Our findings support the identification of the targetome of cancer-related miRNAs as a tool to discover genes and pathways fundamental for tumor development and potential new targets for anti-tumor therapy.
