(Submitter supplied) Constitutive low level DNA damage is linked to innate immune activation. Hierarchical clustering of over 9000 transcripts revealed remarkably similar profiles in a patient with lupus erythematosus and a patient with AGS with up-regulation of genes involved in DNA damage signaling, p53-inducible genes, senescence-associated genes as well as up-regulation of interferon-stimulated genes. Transcriptional profiling of fibroblasts exposed to oxidative stress showed a marked up-regulation of genes involved in DNA replication/repair and replication licensing in TREX1-deficient cells compared to wild type cells suggesting massive replication stress.

(Submitter supplied) Single-stranded DNA (ssDNA) binding protein Replication Protein A (RPA) is essential for protecting ssDNA at replication forks. However, how RPA is loaded to replication forks remains unexplored. Here, we show that Regulator of Ty1 transposition protein 105 (Rtt105) binds RPA and is required for the association of RPA with replication forks. Cells lacking Rtt105 exhibit dramatic genome instability and severe defects in DNA replication. more...

(Submitter supplied) Repair of DNA double-strand break (DSB) is critical for the maintenance of genome integrity. We have previously shown that a class of DSB-induced small RNAs (diRNAs) facilitates homologous recombination (HR)-mediated DSB repair in Arabidopsis thaliana. Here we show that INVOLVED IN DE NOVO 2 (IDN2), a double-stranded RNA (dsRNA) binding protein involved in small RNA-directed DNA methylation, is required for DSB repair in Arabidopsis. more...
