Analysis of the Role of NuMA (TDIF) in DNA repair Through Next Generation Sequencing Techniques [PolII ChIP-seq RPE1]

ABSTRACT: Purpose: To assess NuMA (TDIF)’s role in facilitating PolII pausing Methods:Pol2 ChIP-Seq was carried out in each pairwise combination of untreated/hydrogen peroxide treated and no doxycyclin (NuMA (TDIF) WT)/doxycyclin treated (NuMA (TDIF) KD) RPE1 cells in duplicate. The data was mapped using bwa mem and subsequently used to generate bigwigs showing fold-change relative to inputs using MACS2 and various meta-feature profiles using the CGAT suite of bioinformatics tools Results: The data revealed increased occupancy of PolII at promoter regions and increased pausing ratios for genes in H2O2- cells after NuMA (TDIF) KD relative to controls, but decreased occupancy in NuMA (TDIF) KD in H2O2+ cells compared to controls. Conclusions: Our study indicates that NuMA (TDIF) plays a role in PolII pause-release.

Analysis of the Role of NuMA (TDIF) in DNA repair Through Next Generation Sequencing Techniques [OGAP-seq]

Project description:Purpose: To assess the role of NuMA (TDIF) in DNA repair, NuMA (TDIF) ChIP-seq, 4sU-seq in hydrogen peroxide treated and untreated WT and NuMA (TDIF) KD cells, and OGAP-seq in hydrogen peroxide treated and untreated WT and NuMA (TDIF) KD cells Methods: 4sU-seq was carried out in WT and NuMA (TDIF) KD (using a doxycyclin inducible system) untreated and peroxide treated duplicate RPE cells. The data was mapped using STAR, the bams coverted into bigwigs and differential expression between the conditions carried out using DE-seq2. NuMA (TDIF) ChIP-seq and OGAP-seq data was mapped using BWA. Both sets of mapped data were subsequently used to generate bigwigs showing fold-change relative to inputs using MACS2 and to generate metagene profiles using the CGAT suite of bioinformatics tools. Both sets of data were also run through FeatureCounts to count reads overlapping promoter regions. Results: Through our 4sU-seq data we identified a set of genes whose expression upon exposure to oxidative stress is dependent upon the presence of NuMA (TDIF). NuMA (TDIF) ChIP revealed increased occupancy of NuMA (TDIF) at promoters, which was increased for NuMA (TDIF)-regulated genes, paused genes and early response genes. OGAP-seq in the presence and absence of NuMA (TDIF) demonstrated that in the absence of NuMA (TDIF) there is increased damage across gene bodies and particularly promoters. Conclusions: Our study indicates that NuMA (TDIF) plays a role in the protection from and response to oxidative damage. This protective effect appears to be particularly strong at promoters regions, and may differ between distinct subsets of gene categories.

Analysis of protein interaction partners of TDIF

Project description:Reactive oxygen species (ROS) generated as by-products of metabolism can induce stochastic damage to cellular components including DNA. A localised oxidative damage may arise during transcriptional activation at promoters of protein coding genes. ROS are generated during oxidative demethylation of histones and 5-methyl cytosine in promoter CpG clusters. ROS induced oxidation of DNA bases, mainly 7,8-dihydro-8-oxoguanine (8-oxoG) is normally resolved through a well characterised repair pathway where the oxidised base is first removed by components of base excision repair (BER) pathway, and the resulting breaks in the DNA backbone are subsequently repaired by the single-strand repair (SSBR) machinery that includes TDP1 and XRCC1. In this project we have identified the role of a putative mitotic assembly protein, TDIF in ROS induced single strand break repair. Using semi-quantitative LC-MS/MS and biochemical assays we show that the long isoform of TDIF specifically interacts with SSBR machinery after oxidative damage.
