Project description:We performed global microRNA expression profiling of a cohort of primary melanoma patient samples linked to a well-annotated clinical database. The goal of this study was to identify microRNA that are associated to or correlated with various clinical parameters and patient outcomes. Candidate microRNA were identified for building prognostic models and functional testing.

Project description:MicroRNA profiling was performed on RNA samples matched to those included in the NIH Human Pluripotent Stem Cell Database (Series GSE32923). Twenty undifferentiated human embryonic stem cell lines and 4 human tissues were analyzed. Expanded descriptions of methods used are available at: http://stemcelldb.nih.gov.

Project description:MicroRNA expression profiles of malignant pleural mesothelioma (MPM) specimens were analyzed to identify novel microRNA that are potentially involved in the oncogenic transformation of human pleural cells. In addition to several novel MPM-associated microRNAs, we observed that the expression level of microRNA-1 was significantly lower in tumors as compared to normal pleural specimens. Subsequently, pre-mir of microRNA-1 was introduced into MPM cell lines to overexpress this microRNA. Phenotypic changes of these altered cells were assayed. The cellular proliferation rate was significantly inhibited after overexpression of microRNA-1. Early and late apoptosis were measured by Annexin V and TUNEL assays, respectively. Taken together, these data suggested that overexpression of microRNA-1 induced apoptosis in these MPM cell lines, acting as a tumor suppressor. We confirmed our observations by assessing in the transduced MPM cells cell cycle-related genes, pro-apoptotic and anti-apoptotic genes, which all showed coordinated, significant changes characteristic of the apoptotic phenotype. Thus, further investigation and validation of our microRNA database of MPM may elucidate previously unrecognized molecular pathways and/ or mechanisms by identifying novel microRNAs that are involved in malignant transformation. Our study has now found microRNA-1 to be one of these MPM-associated microRNAs, with potential pathogenic and therapeutic significance.

Project description:The Chinese surf clam (Mactra chinensis) is an economically important clam, distributed in Liaoning and Shandong province. In recently years，because of coastal environmental deterioration and overfishing, the natural population of M. chinensis have considerably declined . In this paper, we study the microRNA transcriptome of gills, including control and experimental group was sequenced through Illumina Hi-seq 2500 CE. And the differential expression was used to find the functional microRNA response to the Cd2+ exposure. Through Illumina Hi-seq 2500, a total of 14,415,256 clean reads and 15,570,111 clean reads were yielded in the gill of control and experimental group respectively. A total of 14,584,077 sRNA, in which there are 12,505,055 sRNA shared by S01 & S02, including 187,859 unique sRNA. The distribution of the sRNA length in the two library was similar, most of them were 26-27 nt. 27 nt was the most abundant length in S01, followded by 28 nt, 26 nt, and 23 nt; 26 nt was the most abundant length in S02, and followed by 27 nt, 28 nt and 23 nt. 50 miRNA was found in unique sRNA, including 38 conserved and 12 novel genes. The most abundant length of microRNA in the two library was the same, 23 nt. Through the analyze of differential expression analysis, the expression of 5 miRNA was induced with significantly difference, and 17 miRNA was down regulated and 28 miRNA was up regulated without significantly difference. So the miRNA in gill of M. chinensis might involve the environmental stress. 542 target genes were yielded when the 50 miRNA were hit to mRNA genome. And the target genes of differential expression miRNA were annotated by hitting to the NCBI database, and 4 genes hit to the COG, 1 genes hit to the GO, 5 genes hit to the KEGG and 11 genes hit to the nr database. The genes hit to the NCBI database include E3 ubiquitin-protein ligase, Wnt signaling pathway and Regulator of G-protein signaling 22.
