The Double Face of Base Excision Repair: Preventing and Triggering Double‐Strand Breaks
Base excision repair is conserved from bacteria to man, robustly eliminating oxidized bases in DNA and reinserting the appropriate nucleotide to restore an intact double helix. Recent results describe conditions and mechanisms that misregulate long‐patch BER to generate double‐strand breaks, triggering chromosome fragmentation and cell death, altering ...

ABSTRACT Mycobacteriophage Mcgavigan could be a promising candidate for use as a preventative agent against infections with Mycobacterium avium subsp. paratuberculosis. Bioinformatic analysis of the Mcgavigan genome revealed the presence of an operon containing a “Bxb1‐like” repressor.

Mechanisms of base selection by the E.coli mispaired uracil glycosylase [PDF]
The repair of the multitude of single-base lesions formed daily in the cells of all living organisms is accomplished primarily by the base-excision repair (BER) pathway that initiates repair through a series of lesion-selective glycosylases.

DNA repair in cancer: emerging targets for personalized therapy [PDF]
Genomic deoxyribonucleic acid (DNA) is under constant threat from endogenous and exogenous DNA damaging agents. Mammalian cells have evolved highly conserved DNA repair machinery to process DNA damage and maintain genomic integrity.

HLA‐Knockout: Enabling Allele‐Specific Knockout of HLA Class I Genes for Immunogenic Engineering
ABSTRACT The interaction between T‐cell receptors (TCRs) and antigenic peptides presented by HLA molecules is fundamental to adaptive immunity. However, the extreme polymorphism of HLA genes poses major challenges for transplantation, antigen discovery, immunotherapy and studies of allele‐specific function.

Mammalian Base Excision Repair: the Forgotten Archangel [PDF]
Base excision repair (BER) is a frontline repair system that is responsible for maintaining genome integrity and thus preventing premature aging, cancer and many other human diseases by repairing thousands of DNA lesions and strand breaks continuously ...

Different DNA End Configurations Dictate Which NHEJ Components Are Most Important for Joining Efficiency [PDF]
The nonhomologous DNA end-joining (NHEJ) pathway is a key mechanism for repairing dsDNA breaks that occur often in eukaryotic cells. In the simplest model, these breaks are first recognized by Ku, which then interacts with other NHEJ proteins to improve ...

XRCC4 deficiency in human subjects causes a marked neurological phenotype but no overt immunodeficiency [PDF]
Background Nonhomologous end-joining (NHEJ) is the major DNA double-strand break (DSB) repair mechanism in human cells. The final rejoining step requires DNA ligase IV (LIG4) together with the partner proteins X-ray repair cross-complementing protein ...

Differential proteomic analysis highlights metabolic strategies associated with balhimycin production in Amycolatopsis balhimycina chemostat cultivations [PDF]
Background Proteomics was recently used to reveal enzymes whose expression is associated with the production of the glycopeptide antibiotic balhimycin in Amycolatopsis balhimycina batch cultivations.
