lncRNA and mRNA-sequencing of WS1 cells after 5Gy of X-Ray irradiation

Project description:Purpose: The goal of this study was to compare the lncRNA and mRNA expression profile of human fibroblast WS1 cells between 0 Gy and 5 Gy X-ray irradiation. Methods: lncRNA and mRNA-sequencing of WS1 cells were generated using Illuminal Hiseq4000, RNA-seq reads were mapped to human genome hg19 by hisat2 software. Cuffdiff software was used to analysis the differentially expressed levels of LncRNA and mRNA FPKM. Results: We identified different expressed levels of 88780 lnRNA and 20311 mRNA transcripts in WS1 cells between 0 Gy and 5 Gy X-ay irradiation. Conclusion: Our study first revealed the detail of lncRNA and mRNA expression profiles of WS1 cells after 5Gy of X-Ray irradiation

Analysis of mRNA expression in human skin fibroblasts WS1 cells between IFI6-overexpression and control upon irradiation.

Project description:This study aims to compared mRNA expression between IFI6-overexpressed WS1 cells and NC by RNA-Seq. In this study, WS1 cells were divided into two groups and each group had four repeats, one group was infected by IFI6-overexpressed lentivirus and another was infected by NC lentivirus. The two groups of cells were then irradiated with a single 5 Gy dose of radiation at a fixed rate of 1.15 Gy/min using an X-ray linear accelerator (Rad Source Technologies Inc., Suwanee, GA, USA). 24 hours post irradiation, WS1 cells from IFI6-overexpression and NC were collected and subjected to mRNA expression analysis.

Next Generation Sequencing Facilitates Quantitative Analysis of 0 and 5 Gy HuR binding RNAs

Project description:Purpose: Next-generation sequencing (NGS) has revolutionized systems-based analysis of RNA. The goals of this study are to compare HuR binding RNAs between 0 or 5 Gy irradiation, and analyze its effect on RNA expression. Methods: Human skin fibroblast cell line WS1 cells were treated with 0 or 5 Gy irradiation. After 24 h, RNA expression was measured using using Illumina HiSeq4000. Meanwhile, RIP was performed using HuR antibody. HuR bound mRNAs after 0 or 5 Gy irradiation was measured using using Illumina HiSeq4000. Results: RIP-sequencing reveals HuR binding RNAs between 0 or 5 Gy irradiation in WS1 cells. RNA sequencing reveals dyeregulated RNAs between 0 and 5 Gy irradiation. Conclusions: Our study represents the first detailed analysis of HuR binding RNAs between 0 and 5 Gy irradiation generated by RNA-seq technology. This study contributes to our understanding of the role of HuR inresponse to radiation.

HuR (ELAVL1) RIP-chip and knockdown exon array

Project description:Integrative regulatory mapping indicates that the RNA-binding protein HuR (ELAVL1) couples pre-mRNA processing and mRNA stability In this dataset, we employed two distinct experiments. 1) HuR RIP-chip to identify mRNA targets of HuR. 2) HuR knockdown to identify mRNAs whose expression are dependent on HuR. All 12 samples were normalized with PLIER using Affymetrix power tools. To identify RNA targets of HuR, HuR RIP samples were compared to Mock RIP samples. To identify RNA regulated by HuR, HuR knockdown samples were compared to mock knockdown samples.

Characterization of protoporphytin IX effects on X-ray irradiation in Hela cells in vitro

Project description:Hela cells were used to evaluate the protoporphytin IX (PpIX) effects on X-ray irradiation. Treatment conditions were (1) control group (untreated cells); (2) cells treated with 1 Œºg /ml PpIX for 6 hours; (3) cells irradiated with 3Gy X-rays; (4) cells treated with 1 Œºg /ml PpIX for 6 hours prior to irradiation with 3Gy X-rays. Hela cells gene expressions in 4 groups were measured at 24 hours after exposure to 0 and 3 Gy X-rays plus treatment with PpIX prior to irradiation.

Quantitative Proteomics analysis of LX-2 Responses to Irradiation and TGF-β1 Description

Project description:The human hepatic stellate cell line LX2 was treated with 8 Gy X-ray irradiation and/or 2ng/ml recombinant human TGF-β1. The iTRAQ-based high throughput quantitative proteomic approach was used to obtain a comprehensive view of the protein ensembles affected by irradiation and/or TGF-β1 treatment on LX2. This study provides clues for further investigation of the mechanisms behind radiation-induced liver fibrosis.

Fe ions and X-ray radiation exposure of Est2-immortalised human coronary artery endothelial cells - 1 day and 7 days post-irradiation

Project description:In recent years there is a growing epidemiological indication of excess risk of cardiovascular disease at low doses of ionizing radiation without a clear-cut threshold. It is proposed that damage to the vascular endothelium is critical in radiation-related cardiovascular diseases. In order to identify and better understand the underlying molecular mechanisms of high LET (Fe ions) and low LET (X-ray) radiation on endothelial cells, we performed a microarray analysis on immortalized human coronary artery endothelial cells irradiated with 2.00 Gy and compared them with sham-irradiated samples. RNA was extracted at different time points after irradiation (1 day, 7 days).
