Degradation mechanism of the von Willebrand factor A2 domain by nattokinase

FEBS Letters, EarlyView.
Nattokinase, a natto‐derived protease, exhibits potent antithrombotic effects. This study demonstrates that nattokinase directly cleaves the von Willebrand factor (vWF) A2 domain in vitro. Unlike the native regulator ADAMTS13, nattokinase degrades folded vWF independently of shear stress.

Alpha1-antitrypsin protects the intestine from ischemia-reperfusion injury in a rat intestinal clamping model

Intestinal Failure
Background: Ischemia-reperfusion injury (IRI) remains a significant hurdle when blood flow is restored to ischemic tissue. Alpha1-antitrypsin (AAT), a serine protease inhibitor, has demonstrated strong anti-inflammatory properties, including inhibition ...

Gastro-Intestinal Failure

, 2017
This chapter summarizes different aspects of gastrointestinal (GI) dysfunction in critically ill patients. Daily evaluation of the abdomen and monitoring of the amount and the aspect of faeces and lost GI secretions are the mainstay of assessment of GI (dys)function; no single reliable test is available.

The ubiquitin‐proteasome system and autophagy as guardians of the cellular proteome

FEBS Letters, EarlyView.
This Perspective covers the three principles governing the crosstalk between the ubiquitin‐proteasome system and autophagy in cellular proteostasis: (1) a shared ubiquitin code routing substrates via shuttle factors or autophagy receptors; (2) spatial compartmentalization into phase‐separated degradation hubs and organelle‐specific modules (exemplified

Microbiome−host proteostasis crosstalk—An emerging perspective on mechanisms and interventions toward healthy longevity

FEBS Letters, EarlyView.
Proteostasis and the gut microbiota play a key role in shaping host physiology. Microbiota‐derived metabolites, vitamins, and RNA modulate host proteostasis. Findings from model systems, including C. elegans, indicate microbes can either stabilize or disrupt host proteostasis.

Resting energy expenditure is not defined by bowel function among patients with intestinal failure

Clinical Nutrition Open Science
Background & Aims: Resting energy expenditure (REE) is a critical parameter for assessing energy requirements in patients with chronic intestinal failure (CIF). This study aimed to investigate the influence of intestinal functionality, defined by the

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

FEBS 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 ...

Multivisceral Transplantation as curative Treatment for patients with Diffuse Splanchnic Arterial Ischemia: a case report

Intestinal Failure
Background: Criteria for multivisceral transplantation (MVTx) have broadened. However, diffuse splanchnic arterial ischemia secondary to visceral arterial thrombosis has only been described once.

Phosphoinositides and inositol phosphates as molecular glues

FEBS Letters, EarlyView.
Inositol phosphates (IPs) and phosphoinositides (PIPs) regulate diverse eukaryotic processes. Beyond recruiting signaling proteins or acting as structural cofactors, recent studies suggest they mediate protein–protein interactions as natural molecular glues.

Three phosphatase families form a community: The phosphohydrolases that act upon inositol pyrophosphates

FEBS Letters, EarlyView.
Inositol pyrophosphates are energy‐rich signaling molecules that perform critical functions in cells. Three different families of phosphatases hydrolyze the β phosphate of the inositol pyrophosphate molecules: two have narrow specificities and one is promiscuous.
