Radiation damage to nucleoprotein complexes in macromolecular crystallography [PDF]
Significant progress has been made in macromolecular crystallography over recent years in both the understanding and mitigation of X-ray induced radiation damage when collecting diffraction data from crystalline proteins.

Calculation of complex DNA damage induced by ions [PDF]
This paper is devoted to the analysis of the complex damage of DNA irradiated by ions. The analysis and assessment of complex damage is important because cells in which it occurs are less likely to survive because the DNA repair mechanisms may not be sufficiently effective.

A mini-review of the diffusion dynamics of DNA-binding proteins: Experiments and models [PDF]
In the course of various biological processes, specific DNA-binding proteins must find a particular target sequence/protein or a damaged site on the DNA efficiently. DNA-binding proteins perform this task based on diffusion. Yet, investigations over recent decades have found that the diffusion dynamics of DNA-binding proteins are generally complicated ...

Nuclear rupture at sites of high curvature compromises retention of DNA repair factors. [PDF]
The nucleus is physically linked to the cytoskeleton, adhesions, and extracellular matrix-all of which sustain forces, but their relationships to DNA damage are obscure. We show that nuclear rupture with cytoplasmic mislocalization of multiple DNA repair

Mechanisms of DNA damage, repair, and mutagenesis
Living organisms are continuously exposed to a myriad of DNA damaging agents that can impact health and modulate disease‐states. However, robust DNA repair and damage‐bypass mechanisms faithfully protect the DNA by either removing or tolerating the ...

Under favorable conditions DNA can survive for thousands of years in the remains of dead organisms. The DNA extracted from such remains is invariably degraded to a small average size by processes that at least partly involve depurination. It also contains large amounts of deaminated cytosine residues that are accumulated toward the ends of the ...

Telomere shortening is an important risk factor for cancer and accelerated aging. However, it is becoming evident that oxidatively damaged DNA within the telomere sequence may also cause telomere dysfunction.

Probing the microscopic structure and flexibility of oxidized DNA by molecular simulations [PDF]
The oxidative damage of DNA is a compelling issue in molecular biophysics as it plays a vital role in the epigenetic control of gene expression and is believed to be associated with mutagenesis, carcinogenesis, and ageing. To understand the microscopic structural changes in physical properties of DNA and the resulting influence on its function due to ...

Inflammation-induced DNA damage and damage-induced inflammation: a vicious cycle [PDF]
Inflammation is the ultimate response to the constant challenges of the immune system by microbes, irritants or injury. The inflammatory cascade initiates with the recognition of microorganism-derived pathogen associated molecular patterns (PAMPs) and ...

Radiation induced DNA damage responses [PDF]
The amazing feature of ionising radiation (IR) as a DNA damaging agent is the range of lesions it induces. Such lesions include base damage, single strand breaks (SSBs), double strand breaks (DSBs) of varying complexity and DNA cross links.
