Engineered sequence-specific nucleases and donor DNA templates can be customized to edit mammalian genomes via the homologous recombination (HR) pathway. Here we report that the nature of the donor DNA greatly affects the specificity and accuracy of the editing process following site-specific genomic cleavage by transcription activator-like effector nucleases (TALENs) and clustered, regularly interspaced, short palindromic repeats (CRISPR)-Cas9 nucleases. By applying these designer nucleases together with donor DNA delivered as protein-capped adenoviral vector (AdV), free-ended integrase-defective lentiviral vector or nonviral vector templates, we found that the vast majority of AdV-modified human cells underwent scarless homology-directed genome editing. In contrast, a significant proportion of cells exposed to free-ended or to covalently closed HR substrates were subjected to random and illegitimate recombination events. These findings are particularly relevant for genome engineering approaches aiming at high-fidelity genetic modification of human cells.

Two artificial imidazole-derived nucleobases, HQIm (3H-imidazo[4,5-f]quinolin-5-ol) and CaIm (imidazole-4-carboxylate), were introduced into short DNA duplexes to systematically investigate their thermal stability upon metal ion coordination. Metal-mediated base pairs are formed with the 3d metal ions CoII, NiII and ZnII, as well as with the lanthanoid ions EuIII and SmIII, which induce a thermal stabilization of up to 8 °C upon binding. The latter are the first lanthanoid-mediated base pairs involving only four donor atoms that result in a significant duplex stabilization.

Foreign body reaction (FBR), an immune-mediated complex healing process, plays a crucial role in integrating implants into the body. Macrophages, as the first line of immune system interaction with implant surfaces, play a bidirectional role in modulating the inflammation-regeneration balance. For a deep understanding and the evaluation of the reactions between implant materials and immune responses, reliable in vitro methods and protocols are pivotal.

Tunneling times were calculated in electron transfer processes using an asymmetric harmonic double-well model. The simplicity of a direct variational calculation in the approximate solution of the Schrödinger equation, along with the interpretation of tunneling times within the probabilistic framework of a two-level system, allows for the efficient and accurate determination of tunneling times with minimal computational cost. These calculations were applied to electron transfer processes in the study of the photosynthetic reaction center and in the context of catalysis in UV-induced DNA lesion repair and are in agreement with the experimental, computational, and theoretical results with which they were compared.

It is influenced by many factors, including environmental exposures, genotype, cell type, sex, and aging. Since age is the primary risk factor for developing neurodegenerative diseases, it is important to determine if aging-related DNA methylation is retained when cells are reprogrammed to an induced Pluripotent Stem Cell (iPSC) state.

Introduction: Aldo-keto reductase 1B10 (AKR1B10) is a multifunctional enzyme, which is important in cancer development and progression, but the landscape of AKR1B10 in pan-cancers and in tumor microenvironment is unclear.
Method: This study integrated the sequencing data of 33 cancer types, including gastric cancer, from TCGA project to explored the expression pattern and genetic and epigenetic alterations of AKR1B10. The association of AKR1B10 expression with clinical progression of cancers was evaluated by Kaplan-Meier analysis; the potential role of AKR1B10 in tumor microenvironment (TME) and immune-related gene expression were analyzed by PURITY, ESTIMATE, TIMER and CIBERSORT algorithms.
