TranscriptomicsExpression data from SKOV3 cells treated with SAHA or vehicle control
We performed a microarray experiment to assess SAHA-induced changes in expression of genes of the homologous recombination DNA repair pathway SKOV-3 ovarian cancer cells were treated with 1µM SAHA or vehicle-control (0.01% DMSO) for 6 or 24 hours, harvested and processed for RNA isolation. Data fo...

GenomicsBRCA1 functions independently of homologous recombination in DNA interstrand crosslink repair
Brca1 is required for DNA repair by homologous recombination (HR) and normal embryonic development. Here we report that deletion of the DNA damage responsefactor 53BP1 overcomes embryonic lethality in Brca1-nullizygous mice, and rescues HR deficiency, as measured by hypersensitivity to PARP (polyADP...

TranscriptomicsMonitoring Homology Search during DNA Double-Strand Break Repair in vivo
Homologous recombination (HR) is crucial for genetic exchange, accurate repair of DNA double-strand breaks and pivotal for genome integrity. HR uses homologous sequences for repair, but how homology search, the exploration of the genome for homologous DNA sequences, is conducted in the nucleus remai...

ProteomicsSART3 promotes homologous recombination repair by stimulating DNA–RNA hybrids removal and DNA end resection
DNA–RNA hybrids triggered by double-strand breaks (DSBs) are crucial intermediates during DSB repair, and their timely resolution requires numbers of RNA helicases, including DEAD box 1 (DDX1). However, how these helicases are recruited to DSB-induced hybrids in time remains largely unclear. Here, w...

TranscriptomicsThe DSIF subunits Spt4 and Spt5 have several unexpected, distinct roles in regulating immunoglobulin class switch recombination
Class-switch recombination (CSR), induced by activation-induced cytidine deaminase, can be divided into two phases: DNA cleavage of the switch (S) regions, and the joining of the cleaved ends of the different S regions. Here, we show that the DSIF complex (Spt4 and Spt5), a transcription elongation ...

ProteomicsProteomics reveals dynamic assembly of repair complexes during bypass of DNA cross-links part 2 of 2: AP-MS DATA (QUBIC)
DNA interstrand crosslinks (ICLs) block replication fork progression by inhibiting DNA strand separation. Repair of ICLs requires sequential incisions, translesion DNA synthesis, and homologous recombination, but the full set of factors involved in these transactions remains unknown. Here we establi...

TranscriptomicsRNA microarray of human cervical cancer cell line HeLa treated with imatinib, mitoxantrone or mitoxantrone+imatinib combination against untreated controls
Critical DNA repair pathways become deranged during cancer development. This vulnerability may be exploited with DNA-targeting chemotherapy. Topoisomerase II inhibitors induce double-strand breaks which are detrimental to the cell, if not repaired. This repair process requires high-fidelity function...

ProteomicsISGylation of H2AX retains MDC1 and facilitates homologous recombination repair causing radioresistance in esophageal adenocarcinoma
High expression of interferon-stimulated gene 15 (ISG15) has been associated with poor survival in patients with esophageal adenocarcinoma (EAC). Like ubiquitin, ISG15 utilizes its C-terminal LRGG motif to post-translationally modify target proteins through a process called ISGylation, thereby influ...
