Metabolomic and lipidomic profiling of plasma and cyst fluid allows the detection and characterization of pancreatic intraductal papillary mucinous neoplasms

Background: Intraductal papillary mucinous neoplasm (IPMNs) of the pancreas may evolve from low- to high-grade dysplasia to invasive cancer. Accurate discrimination of IPMN-associated grade of dysplasia is an unmet clinical need for appropriate …

Validation and automation of a high-throughput multitargeted method for semiquantification of endogenous metabolites from different biological matrices using tandem mass spectrometry

The use of metabolomics profiling to understand the metabolism under different physiological states has increased in recent years, which created the need for robust analytical platforms. Here, we present a validated method for targeted and …

Adipose tissue mitochondrial capacity associates with long-term weight loss success

ObjectivesWe investigated whether (1) subcutaneous adipose tissue (SAT) mitochondrial capacity predicts weight loss success and (2) weight loss ameliorates obesity-related SAT mitochondrial abnormalities.MethodsSAT biopsies were obtained from 19 …

mTORC1 regulates mitochondrial integrated stress response and mitochondrial myopathy progression

Mitochondrial dysfunction elicits various stress responses in different model systems, but how these responses relate to each other and contribute to mitochondrial disease has remained unclear. Mitochondrial myopathy (MM) is the most common …

Host-microbe co-metabolism dictates cancer drug efficacy in C. elegans

Fluoropyrimidines are the first-line treatment for colorectal cancer, but their efficacy is highly variable between patients. We queried whether gut microbes, a known source of inter-individual variability, impacted drug efficacy. Combining two …

CLUH regulates mitochondrial metabolism by controlling translation and decay of target mRNAs

Mitochondria are essential organelles that host crucial metabolic pathways and produce adenosine triphosphate. The mitochondrial proteome is heterogeneous among tissues and can dynamically change in response to different metabolic conditions. …

Faecal and serum metabolomics in paediatric inflammatory bowel disease

BackgroundInflammatory bowel disease [IBD] is considered to result from the interplay between host and intestinal microbiota but its pathogenesis is incompletely understood. While IBD in adults has shown to be associated with marked changes in body …
