Two miRNA signatures for identifying nasopharyngeal carcinoma from head-neck tumors and the normal

ABSTRACT: Reports show that miRNAs have been implicated in various cancers and functions as both oncogenes and tumor suppressors in tumour initiation, progression, and response to treatment. Our study is conducted to identify circulating miRNA profile in NPC patients using whole blood samples with clinical significant diagnostic value. Microarray profiling identified 117 differentially expressed miRNAs (fold change≥1.5) between NPC patients and healthy control and 164 differentially expressed miRNAs (fold change≥1.5) between NPC and HNT patients and healthy control. Among them, we obtain two miRNA signatures to help to diagnose NPC.

Extracellular Vesicles from patients with Antibody-Mediated Rejection induce tubular senescence and endothelial to mesenchymal transition by regulating complement activation through horizontal transfer of miRNAs

Project description:Extracellular vesicles (EV) has been shown to deliver potential microRNA (miRNA) as cargo for specific target cells; effectively, the EV unique nature of the bilayer allows miRNA to be protected from degradation. We used microarray analysis to compare the miRNA profiles of EV isolated from acute antibody-mediated allograft rejection patients (AAMR) and chronic antibody-mediated allograft rejection (CAMR) compared to Tx Controls patients. By microarray miRNA profiling we detected 42 miRNAs downregulated and 34 miRNAs upregulated with FDR < 0.05 and Fold change >2. Principal Component analysis showed that these 76 miRNAs were able to distinguish AMR-derived EV from healthy TX patients. We also investigated whether differences in EV miRNA content could separate AAMR and CAMR patients. We found 9 miRNAs differentially expressed in the two AMR groups (eight downregulated and only one upregulated in AAMR compared to CAMR; effectively, these miRNAs could distinguish AAMR-derived EV from CAMR-derived EV. We then investigated the possible target genes of these miRNAs according to their expression, fold change and the p value; interestingly, several targets were associated to CDKN1A and CDKN2A genes regulation.

Induced of RBM24 expression effect on nasopharyngeal carcinoma cells

Project description:RNA-binding proteins (RBPs) are key components in the determination of miRNA function, as they control different stages of miRNA biogenesis and their localization, degradation and activity. To further investigate the underlying mechanisms of RBM24 in nasopharyngeal carcinoma (NPC) carcinogenesis, we compared the miRNA expression profiles in RBM24 induced and control cells by using human miRNA microarray. Microarray analysis identified 11 commonly upregulated and 12 commonly downregulated miRNAs in RBM24 induced cells. Among the 23 miRNAs, miR-25 ranked highest of all the commonly upregulated genes sorted in ascending order according to fold change values. RBM24 expression was controlled by tetracycline-off system in NPC cells.

Differential expression of microRNA profiles from the peripheral blood of type 1 and type 2 diabetic patients

Project description:Using microarray, we compared the expression of miRNAs from the peripheral blood of male subjects with T1DM and T2DM with healthy controls. Healthy male controls used were age-matched to the T2DM group patients with mean(SD) 37.3 (7.1) years. Subjects with T1DM were younger [23.3(1.6) years]. Expression was compared and validated using quantitative real-time PCR. Statistical testing (ANOVA, P-value <0.05) was performed and fold changes with respect to the control were calculated Systolic BP, fasting glucose, HbA1c, total cholesterol and LDL-cholesterol levels were significantly higher in T2DM subjects compared with controls (P-value <0.05). Compared with controls, we identified 37 differentially regulated miRNAs in DM subjects. Among them, 21 miRNAs were upregulated (2-5 fold change, p-value < 0.05) and 16 miRNAs were downregulated (1.5-2 fold change, p-value < 0.05). These miRNAs had gene putative targets primarily involved in regulating pancreatic development and functions, adipocyte differentiation, insulin signaling and glucose-dependent insulin secretion.

microRNA data involved in Japanese flounder (Paralichthys olivaceus) albinism

Project description:In this study, a high-throughput sequencing strategy was employed to identify the miRNAs involved in P. olivaceus albinism. High-throughput miRNA sequencing identified a total of 475 miRNAs, including 64 novel miRNAs. Furthermore, 33 differentially expressed miRNAs containing 13 up-regulated and 20 down-regulated miRNAs were identified in albino versus normally pigmented individuals (fold change ≥1.5 or ≤0.67 and p≤0.05).

The miRNA expression patterns in WSN-infected A549 cells at various time points post-infection.

Project description:To identify miRNAs that are affected by IAV infection, we adopted a systematic approach, and performed a miRNA microarray analysis using a human alveolar adenocarcinoma cell line, A549, which was infected with a common laboratory strain of influenza A/WSN/33(H1N1) virus (WSN). We compared miRNA expression profiles in A549 cells infected with WSN for 2, 6, and 10 hours at a multiplicity of infection (MOI) of 2. Among 955 miRNAs on the microarray, 209 miRNAs were detected in all three infected A549 samples, but when compared with analysis results from mock-infected A549 cells, most expression changes were less than 1.5-fold , which was consistent with a previous report (Buggele et al., 2013). Therefore, we established 1.5-fold expression change as a threshold to select for miRNAs potentially affected by WSN infection. Further screening revealed 116 miRNAs that underwent 1.5-fold or greater expression changes at any timepoint following WSN infection.

Circulating microRNA profiling by array in dogs with myxomatous mitral valve degeneration (MMVD) and pulmonic stenosis (PS) compared with healthy dogs

Project description:In this study, we aimed to demonstrate expression profiles of circulating microRNAs (miRNAs) in dogs with eccentric or concentric cardiac hypertrophy, and investigate whether there is a difference in miRNA expression according to the type of cardiac hypertrophy. Dogs with myxomatous mitral valve degeneration (MMVD) or pulmonic stenosis (PS) were included in this study, which are the two representative diseases of eccentric or concentric cardiac hypertrophy in dogs, respectively. Circulating miRNAs were isolated from the serum samples of five dogs with MMVD, five dogs with PS, and five healthy dogs. The circulating miRNA expression levels of dogs with MMVD or PS were compared with those of the healthy dogs by microarray analysis (Affymetrix GeneChip miRNA 4.0), using two independent parameters, a fold change cut-off of > 1.5 (up or down regulation) and p-value of < 0.05.
