Dynamics of phosphodiester synthesis by DNA ligase [PDF]
Ligases are essential actors in DNA replication, recombination, and repair by virtue of their ability to seal breaks in the phosphodiester backbone. Ligation proceeds through a nicked DNA-adenylate intermediate (AppDNA), which must be sealed quickly to avoid creating a potentially toxic lesion.

Minimal residual disease (MRD) leads to cancer relapse and poor survival in ovarian cancer. The lack of representative 3D models limits therapy development. The microfluidics‐based high throughput 3D microtumor platform described here generates clinically‐relevant MRD models. The 3D microtumors recapitulate the molecular signatures of MRD from patients.

Characterisation of the SUMO-like domains of Schizosaccharomyces pombe Rad60 [PDF]
The S. pombe Rad60 protein is required for the repair of DNA double strand breaks, recovery from replication arrest, and is essential for cell viability.

XRCC4 and DNA Ligase 4 (LIG4) form a tight complex that provides DNA ligase activity for classical non-homologous end joining (the predominant DNA double-strand break repair pathway in higher eukaryotes) and is stimulated by XLF.

Splicing Systems from Past to Future: Old and New Challenges [PDF]
A splicing system is a formal model of a recombinant behaviour of sets of double stranded DNA molecules when acted on by restriction enzymes and ligase. In this survey we will concentrate on a specific behaviour of a type of splicing systems, introduced by P\u{a}un and subsequently developed by many researchers in both linear and circular case of ...

Capacity of DNA Data Embedding Under Substitution Mutations [PDF]
A number of methods have been proposed over the last decade for encoding information using deoxyribonucleic acid (DNA), giving rise to the emerging area of DNA data embedding. Since a DNA sequence is conceptually equivalent to a sequence of quaternary symbols (bases), DNA data embedding (diversely called DNA watermarking or DNA steganography) can be ...

Combinatory effect of BRCA1 and HERC2 expression on outcome in advanced non-small-cell lung cancer [PDF]
BACKGROUND: BRCA1 is a main component of homologous recombination and induces resistance to platinum in preclinical models. It has been studied as a potential predictive marker in lung cancer. Several proteins modulate the function of BRCA1.

Recent studies have implicated a poorly defined alternative pathway of nonhomologous end joining (alt-NHEJ) in the generation of large deletions and chromosomal translocations that are frequently observed in cancer cells. Here, we describe an interaction

High‐Resolution Patterned Delivery of Chemical Signals From 3D‐Printed Picoliter Droplet Networks
3D‐printed picoliter droplet networks have been fabricated that control gene expression in bacterial populations by releasing chemical signals with precise spatial definition and high temporal resolution. This system of effector release is widely applicable, offering diverse applications in biology and medicine.

DNA double-strand breaks (DSBs) are one of the most lethal forms of DNA damage that is not efficiently repaired in prokaryotes. Certain microorganisms can handle chromosomal DSBs using the error-prone non-homologous end joining (NHEJ) system and ...
