DNA damage and repair following traumatic brain injury
Neurobiology of Disease, 2021 Traumatic brain injury (TBI) is known to promote significant DNA damage irrespective of age, sex, and species. Chemical as well as structural DNA modification start within minutes and persist for days after TBI.

Tyrosine dephosphorylation of H2AX modulates apoptosis and survival decisions. [PDF]
, 2009 Life and death fate decisions allow cells to avoid massive apoptotic death in response to genotoxic stress. Although the regulatory mechanisms and signalling pathways controlling DNA repair and apoptosis are well characterized, the precise molecular ...

DNA polymerase α (swi7) and the flap endonuclease fen1 (rad2) act together in the s-phase alkylation damage response in S. pombe [PDF]
, 2012 Polymerase α is an essential enzyme mainly mediating Okazaki fragment synthesis during lagging strand replication. A specific point mutation in Schizosaccharomyces pombe polymerase α named swi7-1, abolishes imprinting required for mating-type switching ...

PARP3 is a sensor of nicked nucleosomes and monoribosylates histone H2BGlu2
Nature Communications, 2016 Chromosomal single-strand DNA breaks occur frequently and require repair to avoid disease outcomes. Here, the authors show that in bird cells, PARP3 accelerates this repair, and use structural biology and cell biology techniques to reveal details of the ...

TGF-β signaling links E-cadherin loss to suppression of nucleotide excision repair. [PDF]
, 2016 E-cadherin is a cell adhesion molecule best known for its function in suppressing tumor progression and metastasis. Here we show that E-cadherin promotes nucleotide excision repair through positively regulating the expression of xeroderma pigmentosum ...

Damage repair DNA polymerases Y [PDF]
Current Opinion in Structural Biology, 2003 The newly found Y-family DNA polymerases are characterized by low fidelity replication using an undamaged template and the ability to carry out translesion DNA synthesis. The crystal structures of three Y-family polymerases, alone or complexed with DNA and nucleotide substrate, reveal a conventional right-hand-like catalytic core consisting of finger ...
