Project description:We identified a tumor-promoting long non-coding RNA (lncRNA) named lncRNA enabling TGF-beta signaling 1 (LETS1). It was found to potentiate epithelial-to-mesenchymal transition (EMT), cell migration and extravasation in a zebrafish xenograft model. To better dissect the downstream target genes and elucidate the signaling pathways altered by LETS1, we ectopically expressed LETS1 in A549 cells. Total RNA was collected and sent for RNA sequencing analysis. Afterwards, differentially expressed genes were used for the pathway enrichment analysis and gene set enrichment analysis (GSEA).
Project description:We identified a tumor-supressing long non-coding RNA (lncRNA) named lncRNA induced by TGF-beta and antagonizes TGF-beta signaling 1 (LITATS1). It was found to mitigate epithelial-to-mesenchymal transition (EMT), cell migration and extravasation in a zebrafish exnograft model. To better dissect the downstream target genes and elucidate the signaling pathways altered by LITATS1, we depleted LITATS1 by specific shRNAs in A549 cells. Total RNA was collected and sent for RNA sequencing analysis. Afterwards, differentially expressd genes were used for the pathway enrichment analysis and gene set enrichment analysis (GSEA).
Project description:To determine the lncRNA expression profile in ectopic APC overexpressed CRC cell lines and control cells, we uesed lncRNA microArray analysis form Arraystar to examine lncRNA expression profile in ectopic APC overexpressed CRC cell lines and control cells.
Project description:Recent study has revealed that long non-coding RNAs (lncRNAs) perform as important regulators of cellular physiology and pathology, which makes them promising therapeutic and diagnostic entities. We found lncRNA WAKMAR1 is significantly down-regulated in wound-edge keratinocytes from venous ulcer and diabetic foot ulcer compared to the normal wounds. To study the genes regulated by WAKMAR1, we transfected lncRNA GapmeRs into human primary epidermal keratinocytes to inhibit its expression. We performed a global transcriptome analysis of keratinocytes upon inhibition of WAKMAR1 using Affymetrix arrays. We performed a global transcriptome analysis of keratinocytes upon inhibition of WAKMAR1 using Affymetrix arrays.
Project description:The etiology and pathophysiology of endometriosis remain unclear. Accumulating evidence suggests that aberrant mRNA and lncRNA expressions may be involved in the pathogenesis and development of endometriosis. This study therefore aims to survey key TFs, genes and lncRNAs and further understand the mechanism of endometriosis. Paired expression profiling of mRNA and lncRNA in ectopic endometria compared with eutopic endometria were determined by high-throughput sequencing techniques in eight patients with ovarian endometriosis. Our study presents a unique insight into the regulatory network of this enigmatic disorder and possibly provides clues regarding replacement therapy of endometriosis.
Project description:Although accumulating evidence has shown that long non-coding RNAs (lncRNAs) are involved in multiple biological processes, considerably less is known regarding their functions in influenza A virus (IAV) replication. Here, lncRNA expression profiles were determined by RNA sequencing in three pairs of influenza virus A/Puerto Rico/8/34 (H1N1)-infected or uninfected A549 cells.
