Article Abstract
We describe here a human pluripotent stem cell line (hPSC) designed to serve as an acceptor (a "chassis" cell line) for the recombination-mediated cassette exchange (RMCE)-mediated precise insertion of DNA fragments into a safe harbor locus. To enable the use of Flp recombinase for directional insertion, we targeted one of the AAVS1 safe harbor alleles with an excisable negative selection cassette flanked with FRT and FRT3 sites. The generated hPSC line displayed typical colony morphology, pluripotency signatures and normal karyotype. We expect it to provide a useful AAVS1 safe harbor "landing site" for FRT/FRT3-flanked transgenes.

Urinary tract infections (UTIs) are common and burdensome in women. Here, we discuss challenges with our current models of care and how evolving insights into the female urogenital microbiome have advanced the understanding of how we diagnose, treat, and prevent recurrent UTIs in nonpregnant adult women. Traditional care models attribute recurrent UTIs mainly to gastrointestinal sources, resulting in significant emphasis on eradicating pathogens with potential overreliance on antibiotics.

Background: Glucagon-like peptide-1 (GLP-1) medications, recently introduced in the United States for treating type 2 diabetes and obesity, have sparked interest and discussion on social media. Social media has emerged as a prominent platform for the distribution of health information; its vast user base and accessibility make it a popular resource for individuals seeking medical advice. This study characterized GLP-1 medication-related content on Instagram about 3 critical areas of public health: women's health, access from nontraditional settings, and barriers to access.

To develop a curative approach, we established a high-efficiency genome editing platform for human and murine hematopoietic stem-progenitor cells using CRISPR/Cas9, recombinant adeno-associated virus serotype 6. To enhance homology-directed DNA repair while minimizing genotoxicity, we incorporated a new 53BP1 inhibitor, a ubiquitin variant that promotes DNA end resection and significantly increases editing efficiency.

Lactic acid bacteria (LAB) play a vital role in the production of fermented foods, with certain strains being capable of producing exopolysaccharides (EPS) that may enhance the texture and functionality of fermented food products. Among these, bacterial β-glucan produced by LAB - a specific type of EPS - offers favorable rheological properties and potential health benefits, making it particularly valuable for food applications. In this study, a combined phenotypic and genotypic screening strategy was used to identify LAB strains potentially capable of producing β-glucan and suitable for use in food fermentations, with an emphasis on fruit-based products.

In vivo genome editing has the potential to address many inherited and environmental disorders. However, a major hurdle for the clinical translation of genome editing is safe, efficient delivery to disease-relevant tissues. A modality-agnostic reporter animal model that facilitates rapid, precise, and quantifiable assessment of functional delivery and editing could greatly enhance the evaluation and translation of delivery technologies.
