The Impact of Sugar Conformation on the Single-Stranded DNA Selectivity of APOBEC3A and APOBEC3B Enzymes.

The APOBEC3 family of polynucleotide cytidine deaminases has diverse roles as viral restriction factors and oncogenic mutators. These enzymes convert cytidine to uridine in single-stranded (ss)DNA, inducing genomic mutations that promote drug resistance and tumor heterogeneity. Of the seven human APOBEC3 members, APOBEC3A (A3A) and APOBEC3B (A3B) are most implicated in driving pro-tumorigenic mutations.

How to get children moving? The effectiveness of school-based interventions promoting physical activity in children and adolescents - A systematic review and meta-analysis of randomized controlled- and controlled studies.

This systematic review and meta-analysis summarizes the effectiveness of school-based physical activity (PA) interventions on children's and adolescents' PA. As no robust empirical evidence exists regarding what seems to characterize the school-based PA interventions that are most effective, we further aimed to map key factors of particular importance when trying to increase PA in early stages of life through school-based strategies. Intervention effects were calculated as standardized between-group (i.

Identification and biophysical characterization of a novel domain-swapped camelid antibody specific for fentanyl.

Opioid use disorders (OUD) and overdoses are ever-evolving public health threats that continue to grow in incidence and prevalence in the United States and abroad. Current treatments consist of opioid receptor agonists and antagonists, which are safe and effective but still suffer from some limitations. Murine and humanized monoclonal antibodies (mAb) have emerged as an alternative and complementary strategy to reverse and prevent opioid-induced respiratory depression.

A real-time biochemical assay for quantitative analyses of APOBEC-catalyzed DNA deamination.

Over the past decade, the connection between APOBEC3 cytosine deaminases and cancer mutagenesis has become increasingly apparent. This growing awareness has created a need for biochemical tools that can be used to identify and characterize potential inhibitors of this enzyme family. In response to this challenge, we have developed a Real-time APOBEC3-mediated DNA Deamination assay.
