Exosomal microRNA, miR-1246, induces cell motility and invasion through the regulation of DENND2D in oral squamous cell carcinoma

ABSTRACT: To Identify of metastasis-related genes and metastasis-related miRNA in oral squamous cell carcinoma by miRNA profiling of HOC313-Parent, HOC313-LM and their respective exosomes carried out. As a result, miR-342-3p and -1246 were found candidate oncogenic miRNAs. To further identify the target genes of miR-1246 and miR-342-3p, we performed gene expression array analysis with HOC313-LM and HOC313-Parent (HOC313-P) transfected NT, miR-342-3p and miR-1246. Moreover, to identify tumor suppressor genes, gene expression profiles of each of transfected cells and HOC313-LM cells were analyzed by in silico analyses. As a result, DENND2D emerged as the possible target of miRN-1246.

Expression data from human macrophages treate with miR-1246 mimic/inhibitor

Project description:MiR-1246 was found to promote tumorigenesis and metastasis in sevearl cancer types. In the context of tumor microenvironment, tumor-associated macrophages are a central part typically correlated with poor prognosis. We used microarray data to determine the gene expression profile in M2-like macrophages when treated with an overexpression of miR-1246 (conducted by miR-1246 mimic). As controls, we used either scambaled mimic control sequence, or a miR-1246 inhibitor.

Project description:RAW264.7 mouse macrophages were transfected with negative control and miR-342-3p mimics and subjected to microarray analysis 18 hours after the transfection. We used microarray to obtain global mRNA expression data of negative control and miR-342-3p mimics-transfected RAW264.7 cells.

The microRNAs with potential in predicting lung metastasis of triple negative breast cancer

Project description:To identify lung metastasis associated microRNAs in triple negative breast cancer (TNBC), we have employed the commercially available Agilent Human miRNA V19.0 Microarray (Platform GPL19730) as a discovery platform. In comparison with LM-Normal, 11 microRNAs significantly altered in both LM-Met and LM-Tumor, and then three of them (hsa-miR-21-3p, hsa-miR-21-5p and hsa-miR-211-3p) were excluded, which were also up-regulated in RF-Tumor. Consequently, eight deregulated microRNAs were identified to be putatively involved in process of lung metastasis, especially miR-629-3p, which was most up-regulated in both LM-Met and LM-Tumor. To validate the microarray data, we utilized qRT-PCR to assess expression levels of the eight miRNAs in the same samples.

MicroRNA-342-3p is a regulator of hepatocellular carcinoma regression

Project description:Hepatocellular carcinoma (HCC) is a cancer with global impact and largely refractory to current treatments. Novel treatment options are therefore urgently needed. MicroRNAs play important regulatory roles in HCCs and are emerging as promising therapeutic options against HCC. We identified tumor suppressor miRNAs that may attenuate tumor development and contribute to HCC regression. We identified miR-342-3p as a promising tumor suppressor miRNA. To understand how miR-342-3p affects the global landscape of gene expression, we transfected Huh7 human hepatoma cells with either the scramble control, or a mimic for miR-342-3p and performed mRNA expression profiling.

5’ isoforms of miR-1246 have distinct targets and stronger functions compared to canonical miR-1246 in colorectal cancer cells in vitro

Project description:Due to alternative processing pathway and post-transcriptional modifications, precursor miRNAs maturate into various sequence isoforms (isomiRs). These sequence variations may result in the changes of the miRNA seed site, target genes, involvement in signaling pathways and thus function. It is important to mention that knowledge about the targets of isomiR is still poor. To date, isomiR research has only been performed in melanoma, breast, and gastric cancer, but there are no experimental studies conducted in colorectal cancer. Here, we aimed to evaluate the putative targets and functional role in vitro of miR-1246 and its two 5’ isoforms (ISO-miR-1246_a and ISO-miR-1246_G). To our best knowledge, this is the first study showing the important role of 5’isoforms of miR-1246 in colorectal carcinogenesis, while acting on different targetomes and being involved in distinct signaling pathways.

miR-1246 association with distant metastasis and poor prognosis in breast cancer patients

Project description:Circulating microRNAs have recently emerged as a new class of promising non-invasive cancer biomarkers. The purpose of this study was the identification by a high-throughput approach (miRNA microarray) of circulating miRNAs associated with breast cancer-derived distant metastasis. To achieve this goal, we resorted to archival plasma samples collected from patients in the control arm of a randomized clinical trial on stage I breast cancer. We compared plasma miRNA levels in patients that developed distant metastasis after a radical or conservative surgery and in those long-term disease-free. Microarray results were technically and independently validated by Real Time PCR. Subsequent in vitro, in vivo and in silico analyses were performed to investigate the miRNA biological/clinical significance in relation with breast cancer progression. We demonstrated that high circulating miR-1246 levels were associated to distant metastasis and that high tissue expression of this miRNA was correlated with unfavorable outcome in ER+HER2- breast cancer patients. In addition, miR-1246 expression was also found to be related with stem-like features. 64 samples (32 patients with metastasis and 32 patients with no metastasis) were considered from a total of 208 hybridized samples collected between 1987 and 2004 (including 94 paired samples according to tumor ER status, age at drawing, drawing year, time from surgery, 7 additional samples from 'no evidence of disease' (NED) patients, 10 references, 1 healthy donor and 2 replicated samples)

mRNA profiling in enterovirus type 71-infected SH-SY5Y cells after transfection with miR-1246 inhibitor

Project description:Today, the pathogenesis of human enterovirus type 71 (HEV71) infection in human central neural system remains unclear. HEV71 is the major pathogen of hand-foot-and-mouth disease (HFMD), and has been associated with severe neurological disease and even death in infants and young children. We employed the human whole genome microarray analyze the mRNA profiling in human neuroblastoma cells SH-SY5Y infected with HEV71 after transfection. Firstly, SH-SY5Y cells were transfected wtih miR-1246 inhibitor and negtive control respectively using HiPerFect Transfection Reagent according to the manufacturer’s instructions. Then the cells were infected with HEV71 after transfection. After 12 hours infection, the cells were harvested to microarray analysis. The results showed the altered expression of mRNAs including up-regulated genes and down-regulated genes. Overall, this finding will help to understand the functional genes in HEV71-infected human neuroblastoma cells and miR-1246-virus-host interaction. SH-SY5Y cells were transfected wtih miR-1246 inhibitor and negtive control respectively using HiPerFect Transfection Reagent according to the manufacturer’s instructions. Then the cells were infected with HEV71 after transfection. After infection, the cells were harvested to microarray analysis. Total RNA of cells infected with HEV71 was extracted using the TRIZOL Reagent according to the manufacturer's instructions. Gene-expression profiling was performed for each pooling RNA sample separately on the GeneChip_ Porcine Genome Array at CapitalBio Corporation (Beijing, China).
