This open-label, non-randomized study will investigate the use of niraparib in patients with tumors known to have mutations in BAP1 and other select DNA double-strand break repair pathway ...
This is a prospective, single-center, two-phase study to assess the efficacy of single pulsed-dose flutamide in creating double strand breaks (DSBs) in prostate cancer within patients rece...
Purpose 1. To investigate the effects of cardiac imaging radiation on the induction of DNA double-strand breaks by enumerating gamma-H2AX foci in blood lymphocytes and plucked ...
The purpose of this study is to determine whether the administration of the dietary supplement Spermotrend improves spermatogenesis parameters in subjects with male infertility unrelated t...
Unexplained infertility is clinically diagnosed when there are no apparent or clear factors causing infertility on regular infertility assessment tools . Failure of implantation is a possi...
DNA double-strand break (DSB) repair through homologous recombination from BCL10 patient is impaired. Given the relevance of DBS in the onset of cancer, it is important to highlight homologous recombi...
Olaparib is a PARP inhibitor (PARPi). For patients bearing BRCA1 or BRCA2 mutations, olaparib is approved to treat ovarian cancer and in clinical trials to treat breast and pancreatic cancers. In BRCA...
REV1 is one of the major Y-family DNA polymerases. It not only functions as a scaffold protein to mediate other specialized DNA polymerases to sites of lesions, but also inserts deoxycytidine across t...
The CRISPR/Cas9 nuclease system can effectively suppress the replication of the hepatitis B virus (HBV), while covalently closed circular DNA (cccDNA), a highly resistant form of the virus, persists i...
FANCA is a key player in the canonical Fanconi anemia (FA) repair pathway. We have recently shown that FANCA also plays an important role in the single-strand annealing sub-pathway (SSA) of DNA double...
Endonucleases that remove 5' DNA sequences from a DNA structure called a DNA flap. The DNA flap structure occurs in double-stranded DNA containing a single-stranded break where the 5' portion of the downstream strand is too long and overlaps the 3' end of the upstream strand. Flap endonucleases cleave the downstream strand of the overlap flap structure precisely after the first base-paired nucleotide, creating a ligatable nick.
A DNA-binding protein that mediates DNA REPAIR of double strand break, and GENETIC RECOMBINATION.
DNA TOPOISOMERASES that catalyze ATP-independent breakage of one of the two strands of DNA, passage of the unbroken strand through the break, and rejoining of the broken strand. DNA Topoisomerases, Type I enzymes reduce the topological stress in the DNA structure by relaxing the superhelical turns and knotted rings in the DNA helix.
A component of the MRN complex along with Rad50 and Nibrin. Together, these perform a critical function in the repair of DOUBLE-STRANDED DNA BREAKS; RECOMBINATIONAL DNA REPAIR; maintenance of TELOMERE integrity and MEIOSIS. MRE11, which contains a poly(ADP)-ribose binding motif and associates with PARP1, possesses single-strand endonuclease activity and double-strand-specific 3'-5' exonuclease activity. Mutations in the MRE11 gene are associated with ATAXIA-TELANGIECTASIA-like disorder 1.
Eukaryotic enzymes of the DNA TOPOISOMERASES, TYPE I class that catalyze ATP-independent breakage of one of the two strands of DNA, passage of the unbroken strand through the break, and rejoining of the broken strand. These eukaryotic enzymes reduce the topological stress in the DNA structure by relaxing both negatively and positively supercoiled DNA.
