Project description:RNA profiling by RNA-Seq analyses showed that in comparison with the control Dotap-treated cells, miR-574-5p transfection for 24 h resulted in significant up-regulation of 277 genes and down-regulation of 80 genes by at least 2-fold in the miR-574-5p-transfected splenocytes. Gene ontology and pathway enrichment analyses showed that the 277 significantly up-regulated genes in miR-574-5p-transfected cells were highly enriched and clustered in pathways associated with interferon and cytokine signaling, antiviral mechanisms, translesion synthesis and autoimmunity .

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:Prognostication of Breast Cancer (BC) relies largely on traditional markers such as hormone or growth factors but due to their suboptimal specificities, it is challenging to identify the subset of patients who are likely to undergo recurrence and markers of higher specificity are sought to guide therapies. MicroRNAs (miRNAs) are small non-coding RNAs which function as post-transcriptional regulators of gene expression and have shown promise as potential prognostic markers in several cancer types including BC. In our study, we sequenced 104 breast tumor tissue samples and 11 apparently healthy normal breast tissues for miRNAs. Two widely used approaches were adopted to identify prognostic markers â Case-control and Case-only. For both the approaches, Cox-proportional hazards regression model and risk score analysis was performed to identify miRNA signature independent of potential confounders. Representative miRNAs were validated using qRT-PCR. Gene ontology terms were identified for miRNAs significant in survival analysis. A total of 1,423 miRNAs were captured from the tissues, of which 126 were retained with predetermined criteria for good read counts. In the case-control approach, 80 miRNAs were differentially expressed, from which four and two miRNAs were significant for OS and RFS respectively. In the case-only approach, from 147 miRNAs, 11 and four miRNAs were significant for OS and RFS respectively, in which miR-574-3p and miR-660-5p were novel and were not previously found to be associated with BC prognosis. Multivariate Cox analysis indicated that the risk scores calculated in both the approaches were potential independent prognostic factors for BC. Targets for the identified miRNAs were enriched for cell proliferation, invasion and migration. Identification of miRNAs as prognostic markers for breast cancer
