Expression signatures of human HeLa cells with RNAi targetting A1 hnRNP, FUS, H hnRNP and p68-DDX5

ABSTRACT: Transcription profiling of human HeLa cells (cervical cancer cell line) transfected with a plasmid expressing shRNAs cloned into the pSuper expression vector compared to emprty vector negative controls for transfection. Four different RNA interference treatments targetted: A1 hnRNP (HNRNPA1, Heterogeneous nuclear ribonucleoprotein A1); FUS (fusion gene, involved in t(12;16) in malignant liposarcoma); H hnRNP (HNRNPH1); and p68 helicase (DDX5, DEAD (Asp-Glu-Ala-Asp) box polypeptide 5). Keywords: genetic modification

Keywords: genetic modification Five-condition experiment, where HNRNPA1, FUS, HNRNPH1 and DDX5 gene product levels were inhibited by siRNA transfection and compared to transfection with the negative control (scrambled siRNA). Biological replicates: 2 of each of the first three treatments and 3 of the treatment against DDX5, all independently grown and harvested. No technical replicates were performed.

Alternative splicing signatures in apoptosis related genes of human HeLa cells with RNAi targeting p68 RNA helicase-DDX5

Project description:Alternative splicing profiling of apopotosis related genes in human HeLa cells (cervical cancer cell line) transfected with a plasmid expressing shRNAs targetting p68 helicase (DDX5, DEAD (Asp-Glu-Ala-Asp) box polypeptide 5) cloned into the pSuper expression vector compared to empty vector. Keywords: treated vs. untreated comparison; alternative splicing Two-condition experiment, where the p68 DDX5 gene product levels was inhibited by siRNA transfection and compared to transfection with the negative control (scrambled siRNA). Biological replicates: 2, all independently grown and harvested. A dye swapping technical duplicate was performed for each biological replicate. Samples were hybridized onto a 44290 feature array designed by ExonHit to detect splicing events in apopotosis related genes and manufactured by Agilent using in situ synthesis of oligonucleotides by SurePrint technology.

hnRNP A1 iCLIP

Project description:This experiment identifies hnRNP A1 binding sites transcriptome-wide in Hela cells. HeLa cells with inducible expression of T7-tagged hnRNP A1 were grown to approximately 90% confluence and then subject to iCLIP analysis (following the protocol from Huppertz et al. 2014 (iCLIP: protein-RNA interactions at nucleotide resolution)). The iCLIP library was sequenced using Illumina's HighSeq 1500

RNAseq of human Multiple Sclerosis cortex with hnRNP A1 dysfunction

Project description:We sought to identify alterations in RNA expression and splicing in human grey matter from the brains of people with Multiple Sclerosis (MS) where we observe mislocalization of the RNA binding protein hnRNP A1. Thus, RNA was extracted from fresh-frozen post-mortem brain samples of three people with MS and compared to RNA extracted from fresh-frozen post-mortem brain samples of three healthy controls by RNAseq. Regions of interest in human grey matter were defined by immunostaining for hnRNP A1 to confirm grey matter regions with hnRNP A1 mislocalization in MS tissue, and grey matter regions with normal hnRNP A1 localization in control tissue, and the same region from an adjacent tissue section was dissected with a razor blade and used for RNA extraction and sequencing.

CLIPseq of hnRNP A1 from the spinal cords of mice with experimental autoimmune encephalomyelitis

Project description:Experimental autoimmune encephalomyelitis (EAE) is a mouse model for multiple sclerosis (MS) a chronic autoimmune disease of the central nervous system. We have observed dysfunction of the RNA binding protein hnRNP A1 in neurons from the brains of patients with MS, and the spinal cords of mice with EAE. Here, we sought to characterize the consequences of EAE-induced dysfunction of hnRNP A1 on the RNAs it binds by using CLIPseq to establish both the normal central nervous system RNA binding profile of hnRNP A1 in the spinal cords of naive mice, and any alterations to the binding profile of hnRNP A1 in the spinal cords of mice with EAE.

p68 SMC differentiation

Project description:This project investigates the function of p68/p72 in muscle gene expression and skeletal C2C12 cell differentiation. p68/p72 in C2C12 cells cultured in either growth medium (GM) or differentiation medium (DM) was knocked down using shRNA p68/p72 retrovirus, and globle gene expression was profiled using Affymetrix MOE 430A and 430B GeneChip. Keywords: Time-Series

Effects of hnRNP A1 on gene expression in oral squamous cell carcinoma

Project description:To find the discover target genes regulated by hnRNP A1 in oral squamous cell carcinoma, NimbleGen 12x135K microarrays were used to find the gene expression changes between hnRNP A1 or non-specific (NS) siRNA treated oral cancer cells. Cal27 cells were treated with hnRNP A1 or non-specific (NS) siRNA twice in a 48-hour interval. After 96 hours, total RNAs were collected for microarray assay. Total RNAs from hnRNP A1 knockdown (3 samples) or NS siRNA treated cells (3 samples) were used for chip experiment (6 chips). Each chip measures the expression levels of human 45,033 genes. NimbleGen One-Color DNA Labeling Kit was used for sample labeling. Hybridization was performed in NimbleGen Hybridization System. After washing, slides were scanned with Axon GenePix 4000B scanner. Data was extracted and normalized using NimbleScan v2.5 Software.
