Project description:Mammals have evolved an XY sex chromosome system, resulting in dosage imbalance not only between sexes, but also between X-chromosome and autosome. mRNA profiles of 9 pairs of human endometrial carcinoma and adjacent tissues were generated by Illumina 100-nucleotide paired-end sequencing
Project description:Determine differetiatial expression of micro RNA in paired human hepatocellular tumor tissues and their adjacent cirrosis tissues by SOLiD sequencing. http://www.appliedbiosystems.com/absite/us/en/home/applications-technologies/solid-next-generation-sequencing/small-rna-analysis.html Matrix with results is available in thearchive: E-MTAB-511.additional.zip
Project description:The aim of this study is to identify by Next Generation Sequencing - RNA-seq profiling a molecular signature of Hepatocellular Carcinoma samples that correlates with survival. The samples were retrospectively derived from hepatocellular carcinoma tissue as well as non-tumor tissue from the livers of the same patients. The bioinformatical analysis of 32 pairs RNA-seq datasets were obtained from human RNAs on Illumina Hiseq-PE150. Due to the lack of biological sample duplication, this datasets were used hisat2 2.1.0 and gfold v1.1.4 for expression analysis to identify differences in gene expression between tumors and adjacent tissues. (including up- and down-regulation).
Project description:Circular RNAs (circRNA) are a novel class of widespread non-coding RNAs (ncRNAs) that regulate gene expression in mammals. Recent studies demonstrate that functional peptides can be encoded by short open reading frames (sORFs) in ncRNAs, including circRNAs. In this study, through deep RNA sequencing on human endometrial cancer (EC) samples and their paired adjacent normal tissues, we uncovered that the circRNA hsa-circ-0000437 is significantly reduced in EC compared to matched paracancerous tissue. The hsa-circ-0000437 contains a sORF encoding a functional peptide termed as CORO1C-47aa. Overexpression of CORO1C-47aa is capable of inhibiting angiogenesis at the initiation stage by suppressing endothelial cell proliferation, migration, and differentiation through competing with TACC3 to bind to ARNT and suppress VEGF. The anti-tumor effects of CORO1C-47aa on EC progression suggest that CORO1C-47aa has a potential value in anti-carcinoma therapies and deserves further investigation.
Project description:The incidence of keratinocyte-derived skin cancer, cutaneous squamous cell carcinoma (cSCC) is increasing worldwide making it the second most common metastatic skin cancer. In this project we used SOLiD next generation sequencing to characterize gene expression profiles in normal human epidermal keratinocytes (NHEKs) and cSCC cell lines. Total RNAs from normal human epidermal keratinocytes (NHEKs) (n=4) and cSCC cell lines (n=8) were extracted. The samples were sequenced using SOLiD next generation sequencing.
Project description:Pancreatic ductal adenocarcinoma (PDAC) is one of the most lethal malignany and currently the fourth leading cause of cancer related death worldwide. Circular RNAs (circRNAs) are a kind of novel noncoding RNA with a covalently circular structure arise from the non-canonical splicing of precursor-mRNA(pre-mRNA). To identify circRNAs involved in the progression of PDAC, next-generation sequencing (NGS) was performed in five paired PDAC and normal adjacent tissues. Our results suggest that the differential expressed circRNAs in PDAC tissues and normal adjacent tissues associated with the metastasis of PDAC.
