[PMID: 34507247 DOI: 10.1016/j.cyto.2021.155689] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/03/2021] [Revised: 07/20/2021] [Accepted: 08/18/2021] [Indexed: 12/01/2022]
Abstract
BACKGROUND Prevention of acute rejection is the key of the success of liver transplantation. However, there are no specific indicators available for prediction of acute rejection after liver transplantation. MicroRNAs (miRNAs) are highly conserved and small noncoding RNA molecules that can be detected in peripheral blood. Here, we evaluated the potential of circulating miRNAs to serve as noninvasive biomarkers for acute rejection after liver transplantation in rats. METHODS The liver grafts retrieved from Lewis rats were orthotopically transplanted into BN rats or Lewis rats in the acute rejection and immune tolerance group respectively, and the BN rats in the immune intervention group was intraperitoneally injected with transforming growth factor-β1 overexpressed immature dendritic cells to suppress acute rejection before orthotopically transplanted with livers from Lewis rats. MiRNAs profiling studies were used to determine the regulation of circulating miRNAs in plasma samples of rats. Candidate miRNA was verified by quantitative reverse transcriptase polymerase chain reaction. Furthermore, the relationship between candidate miRNA and acute rejection was also evaluated. RESULTS Microarray analysis revealed that miR-199a-3p was the mostly differentially regulated miRNAs in plasma samples among the three groups. The plasmid PCDH-CMV-EGFP-hTGF-β1 was identified by PCR and DNA sequencing, and successfully expressed in imDCs. There were differences in the expression of miR-199a-3p in the liver tissues of the AR group on the 3rd, 7th and 10th day after liver transplantation (all p < 0.01). With time, the RAI score increased gradually, and the difference of miR-199a-3p expression gradually increased (rs = 0.92, p < 0.001), suggesting that it may be related to acute rejection. The expression of miR-199a-3p in the serum of the AR and TGF-β1-imDCs groups gradually increased, reaching a peak at day 7 and then decreasing. There was positive relationship between the expression of miR-199a-3p and RAIs within 7 days post operation. (rs = 0.942, p < 0.05). CONCLUSION miR-199a-3p might be an early warning marker for acute rejection after liver transplantation in rats.

Abstract
Undifferentiated soft tissue sarcomas (UDSTSs) are a group of mesenchymal tumors that remain a diagnostic challenge because of their morphologic heterogeneity and unclear histologic origin (Peters et al., Mod Pathol28: 575 [2015]). In this case report, we present the first multiomics molecular signature for a BCOR–CCNB3 sarcoma (BCS) that includes mutation analysis, gene expression, DNA methylation, and micro RNA (miRNA) expression. We identify a paucity of additional mutations in this tumor and detail that there is significant dysregulation of gene expression of epigenetic remodeling agents including key members of the PRC, Sin3A/3b, NuRD, and NcoR/SMRT complexes and the DNA methyltransferases DNMT1, DNMT3a, and DNMT3b. This is accompanied by significant DNA methylation changes and dysregulation of multiple miRNAs with known links to tumorigenesis. This study significantly increases our understanding of the BCOR effects on fusion-positive undifferentiated sarcomas at both the genomic and epigenomic level and suggests that as better-tailored and more refined treatment algorithms continue to evolve, epigenetic modifying agents should be further evaluated for their efficacy against these tumors.

Abstract
Malignant melanoma is one of the most dangerous tumor types due to its high metastasis rates and a steadily increasing incidence. During tumorigenesis, the molecular processes of embryonic development, exemplified by epithelial-mesenchymal transition (EMT), are often reactivated. For melanoma development, the exact molecular differences between melanoblasts, melanocytes, and melanoma cells are not completely understood. In this study, we aimed to identify microRNAs (miRNAs) that promote melanoma tumorigenesis and progression, based on an in vitro model of normal human epidermal melanocyte (NHEM) de-differentiation into melanoblast-like cells (MBrCs). Using miRNA-sequencing and differential expression analysis, we demonstrated in this study that a majority of miRNAs have an almost equal expression level in NHEMs and MBrCs but are significantly differentially regulated in primary tumor- and metastasis-derived melanoma cell lines. Further, a target gene analysis of strongly regulated but functionally unknown miRNAs yielded the implication of those miRNAs in many important cellular pathways driving malignancy. We hypothesize that many of the miRNAs discovered in our study are key drivers of melanoma development as they account for the tumorigenic potential that differentiates melanoma cells from proliferating or migrating embryonic cells.

Front Immunol 2019; 10:2643. [PMID: 31803183 PMCID: PMC6874100 DOI: 10.3389/fimmu.2019.02643] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/20/2019] [Accepted: 10/24/2019] [Indexed: 12/21/2022] Open
Abstract
Cystic fibrosis (CF) results from deficient CF transmembrane conductance regulator (CFTR) protein activity leading to defective epithelial ion transport. Pulmonary degradation due to excessive inflammation is the main cause of morbidity and mortality in CF patients. By analysing miRNAs (small RNAseq) in human primary air-liquid interface cell cultures, we measured the overexpression of miR-636 in CF patients compared to non-CF controls. We validated these results in explant biopsies and determined that the mechanism underlying miR-636 overexpression is linked to inflammation. To identify specific targets, we used bioinformatics analysis to predict whether miR-636 targets the 3′-UTR mRNA regions of IL1R1 and RANK (two pro-inflammatory cytokine receptors), IKBKB (a major protein in the NF-κB pathway), and FAM13A (a modifier gene of CF lung phenotype implicated in epithelial remodelling). Using bronchial epithelial cells from CF patients to conduct a functional analysis, we showed a direct interaction between miR-636 and IL1R1, RANK, and IKBKB, but not with FAM13A. These interactions led to a decrease in IL1R1 and IKKβ protein expression levels, while we observed an increase in RANK protein expression levels following the overexpression of miR-636. Moreover, NF-κB activity and IL-8 and IL-6 secretions decreased following the transfection of miR-636 mimics in CF cells. Similar but opposite effects were found after transfection with an antagomiR-636 in the same cells. Furthermore, we demonstrated that miR-636 was not regulated by Pseudomonas aeruginosa in our model. We went on to show that miR-636 is raised in the blood neutrophils, but not in the plasma, of CF patients and may have potential as a novel biomarker. Collectively, our findings reveal a novel actor for the regulation of inflammation in CF, miR-636, which is able to reduce constitutive NF-κB pathway activation when it is overexpressed.
