Reconstructing enzyme evolution by protein engineering
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 ...

Microbiome‐blood–brain barrier interactions in aging — mechanisms and therapeutic potential
Aging reshapes the gut microbiome (↓SCFA‐producing commensals; ↑pro‐inflammatory outputs), shifting circulating metabolites (↓SCFAs; ↑LPS, ↑TMAO, ↑PAA) that act at the BBB to increase nonspecific transcytosis, alter transport, and promote astrocyte reactivity, heightening brain vulnerability.

An epithelial GPR35 isoform supports tumor‐associated transcriptional and metabolic phenotypes
GPR35 generates two functionally distinct isoforms with previously unresolved roles. GPR35‐short mediates immune‐cell chemotaxis, while GPR35‐long is enriched in colorectal cancer epithelium, where it supports increased metabolism, proliferation, and tumor‐associated transcriptional programs.

Ultrasound diagnostics ofbowel diseases in adults
Ultrasonography is the first step in the diagnosis of acute and chronic diseases of the abdominal cavity by imaging methods. In an increasing number of cases ultrasound examination is used to diagnose lesions located in the intestines, which beside the

Structure‐forward targeting of claudins with synthetic binders
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.

P446 The INTESTINE study: INtended TEmporary STomas In crohN's diseasE
Background Patients with ileocolic Crohn’s disease may require surgery resulting in temporary stoma formation. The impact on quality of life and morbidity related to stomas is well recognised and timely reversal should be targeted to ...

Animals must match their growth rate to available nutrients. We show that in Drosophila larvae, the nutrient‐sensing TOR kinase controls growth by regulating levels of TFAM, a key regulator of mitochondrial function, in the adipose tissue. When nutrients are abundant, high TOR activity suppresses TFAM, lowering mitochondrial bioenergetic activity and ...

Comparative Assessment of D-Xylose Absorption between Small Intestine and Large Intestine
The present study aimed to evaluate the absorption of D-xylose, a passively absorbed five-carbon monosaccharide, from the large intestine compared with the small intestine, in order to explore the absorption potential of the large intestine.

Distinct human stem cell populations in small and large intestine [PDF]
The intestine is composed of an epithelial layer containing rapidly proliferating cells that mature into two regions, the small and the large intestine. Although previous studies have identified stem cells as the cell-of-origin for intestinal epithelial ...
