Project description:We aimed to characterize decoy to the RNA-binding protein CUG-RNA binding protein 1 (CUGBP1 mechanism in A549 lung cancer cells. We identified several new canonical targets of CUGBP1 but those were not regulated by miR-574-5p via the decoy mechanism. This can be explained by the localization of CUGBP1 and miR-574-5p in the nucleus, where CUGBP1 regulates alternative splicing. Next, we analyzed the 3’UTRs of potential targets and found that the decoy-dependent regulation of mPGES-1 splicing is unique. Therefore, we postulate that in A549 cells mPGES-1 is the only protein regulated by the decoy mechanism of CUGBP1 and miR-574-5p which suggests that the decoy mechanism allows the specific regulation of the expression of distinct targets.

Project description:Purpose: The target mRNAs of miR-574 in mouse heart are unknown. The goal of this study is to use next generation sequencing (NGS) RNA-seq followed by quantitative reverse transcription polymerase chain reaction (qRT-PCR) methods to identify the downstream target genes that are directly regulated by miR-574 in murine hearts at the mRNA level. Results: Using a well established data analysis workflow from the Genomic Research Center from University of Rochester Medical Center, we analyzed RNA-seq data. We have identified novel genes that are regulated by miR-574 via miRNA-induced silencing complex (miRISC). We defined differentially regulated genes (either upregulated or downregulated) with statistical significance in total RNA expression change (p value <0.05 for differential expressed genes). We identified 34 upregulated genes involved in the small molecule metabolism and the mitochondrial function, and 49 downregulated genes in the electron transport chain (ETC) complex, oxidative phosphorylation, and tricarboxylic acid cycle. Conclusions: Among 34 upregulated genes, eight genes contain the predicted target seed sequence of miR-574-5p and Fam210a (family with sequence similarity 210 member A) is the only upregulated gene that contains the target seed sequence of both the guide strand miR-574-5p and the passenger strand miR-574-3p. We confirmed that FAM210A was the downstream target of both miR-574-5p and miR-574-3p in vivo and in vitro. Based on our results, we conclude that miR-574 downregulates a limited number of mitochondrial function related genes including FAM210A in mouse hearts at baseline.

Project description:Two miRNA arms from the same precursor, miR-574-5p and miR-574-3p, were reversely expressed and played exact opposite role in gastric cancer progression. miR-574-5p/-3p ratio was also strongly correlated with higher TNM stages and shorter survival of patients. The increase of miR-574-5p/-3p ratio, or the arm-imbalance of miR-574 was due to the dynamic expression of their highly complementary targets in gastric carcinogenesis. The arm imbalance of miR-574 in turn strongly contributed to and further promoted gastric cancer progression. Conclusion: Our findings indicated that targets mediated miR-574 arm-imbalance contributed to gastric cancer progression. Re-modification of the miR-574-targets homeostasis may represent a realistic approach for gastric cancer prevention and therapy.

Project description:Plasma from 245 patients with advanced NSCLC who received nivolumab as second-line therapy was collected and analyzed. EV-miRnome was profiled on 174/245 patients by microarray platform and selected EV-miRs were validated by qPCR. A prognostic model combining EV-miR and clinical variables was built using stepwise Cox regression analysis and tested on an independent patient cohort (71/245). EV-PD-L1 gene copy number was assessed by digital PCR. For 54 patients with disease control, EV-miR changes at best response versus baseline were investigated by microarray and validated by qPCR. EV-miRNome profiling at baseline identified two EV-miR (miR-181a-5p, miR-574-5p) that, combined with performance status, are capable of discriminating patients unlikely from those that are likely to benefit from immunotherapy (median overall survival of 4 months or higher than 9 months, respectively). EV-PD-L1 digital evaluation reported higher baseline copy number in patients at increased mortality risk, without improving the prognostic score. Best response EV-miRNome profiling selected six deregulated EV-miRs (miR19a-3p, miR-20a-5p, miR-142-3p, miR-1260a, miR-1260b, miR-5100) in responding patients. Their longitudinal monitoring highlighted a significant downmodulation already in the first treatment cycles, which lasted more than six months.

Project description:To compare the miRNA profiles in exosomes derived from optineurin gene knockdown (Optn-KD)BV2s cells and wild type (WT) BV2 cells, BV2 cells were divided into two groups, Optn-KD group or WT group. We treated the Optn-KD group with Optn siRNA for 24 hours. Then, MiRNA profiles for each group were examined by Illumina HiSeq4000. We found differentiated miRNA profiles in the two groups. Compared with WT BV2 cell-derived exosomes, 4 miRNAs (miR-125b-5p, miR-351-5p, miR-505-5p, miR-novel-chr8_37700) were up-regulated and 2 miRNAs (miR-574-5p, miR-99b-5p) were down-regulated in Optn-KD BV2 cell-derived exosomes. This study provides a framework for characterizing the exosomal-miRNAs in Optn-KD BV2 cells.

Project description:We report the application of transcriptome sequencing for investigating of the hsa-miR-371a-5p and hsa-miR-518a-3p regulated genes. JAR, JEG-3 and BeWo choriocarcinoma cells were transfected with hsa-miR-371a-5p or hsa-miR-518a-3p inhibitors or control inhibitors. Totally, 237, 132 and 277 genes with > 2 folds change and adjusted P < 0.05 were upregulated in JAR, JEG-3 and BeWo cells respectively after hsa-miR-371a-5p knockdown. Meanwhile, 229, 269 and 191 genes were upregulated in JAR, JEG-3 and BeWo cells respectively after hsa-miR-518a-3p knockdown. The top upregulated genes included many oncogenes or oncogenesis associated ones. Enrichment analysis showed hsa-miR-371a-5p and hsa-miR-518a-3p regulated diverse pathways related to tumorigenesis and metastasis. Our results would be helpful for the searching of early molecular biomarkers and therapeutic targets for gestational trophoblastic neoplasia.
