Salmonella lipopolysaccharide‐containing supported lipid bilayers as platforms to study bacteriophage interactions

open access: yesFEBS Letters, EarlyView.
We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...

From mice to humans—divergent strategies for intestinal homeostasis and regeneration

open access: yesFEBS Letters, EarlyView.
Recent advances such as organoid genome editing, xenotransplantation, imaging, and whole‐genome sequencing have enabled direct studies of human intestinal stem cells (ISCs). These studies reveal species‐specific features, including slower ISC proliferation, distinct injury responses, slower somatic mutation accumulation in humans, and an inverse ...

Reconstructing enzyme evolution by protein engineering

open access: yesFEBS Letters, EarlyView.
Natural enzyme evolution can be retraced by protein engineering methods such as directed evolution, rational design, and ancestral sequence reconstruction. These approaches reveal how enzymes emerged from ligand‐binding scaffolds, developed varying substrate preferences, formed oligomeric complexes, adapted to environmental changes, and evolved novel ...

Desiccation to DNA: Bulk DNA Metabarcoding of Macroinvertebrate Egg Banks via Sugar‐Flotation Enhances Biodiversity Surveys of Dry Salt Lakes

open access: yesEcology and Evolution
Ephemerally inundated salt lakes in arid regions support unique aquatic macroinvertebrate communities that typically persist through dry periods as resistant resting‐stages (e.g., spores, eggs).

A machine learning framework to trace tumor tissue-of-origin of 13 types of cancer based on DNA somatic mutation.

open access: yesBiochimica et Biophysica Acta - Molecular Basis of Disease, 2020
Carcinoma of unknown primary (CUP), defined as metastatic cancers with unknown cancer origin, occurs in 3-5 per 100 cancer patients in the United States.

Structure‐forward targeting of claudins with synthetic binders

open access: yesFEBS Letters, EarlyView.
Claudins form the paracellular barriers between epithelial and endothelial tissues at tight junctions and are targets for molecular binders with the goal of modulating barrier permeability. Claudin‐binding molecules are relevant in drug delivery or in altering claudin interactions with disease‐causing proteins.

Curves of fixed points of trace maps [PDF]

open access: yes, 2007
We study curves of fixed points for certain diffeomorphisms of ${\mathbb{R}}^3$ that are induced by automorphisms of a trace algebra. We classify these curves.

Evaluation of Extraction Methods for the Recovery of Vertebrate DNA From Spider Webs

open access: yesEnvironmental DNA
Spider webs have recently been recognized as an excellent source of vertebrate eDNA. Here we compare four sample preparation methods and three commercially available DNA extraction kits to optimize vertebrate eDNA recovery. We assessed DNA yield, purity,

Optimising Vaginal Microbiome Profiling for Clinical Translation: A Comparative Assessment of Sample Storage Methods and a Vagina-Specific 16S rRNA Gene Database

open access: yesMicroorganisms
Vaginal microbiome composition has been linked to risk of preterm birth (PTB), a persistent global health challenge. 16S rRNA microbial profiling has identified specific vaginal community state types (CSTs) that have been associated with PTB risk ...

Liver organoids: modelling complexity in homeostasis and disease

open access: yesFEBS Letters, EarlyView.
Studying liver in vitro has been challenging because simple 2D cell cultures fail to capture liver's cellular and architectural complexity. To bridge this gap, scientists increasingly use organoids, 3D liver models which better mimic liver composition and function. This review examines recent advances in liver organoid complexity and realism, discusses
