MetabolomicsDynamic utilization of low-molecular-weight organic substrates across a microbial growth rate gradient

AIM: Low-molecular-weight organic substances (LMWOSs) are at the nexus between micro-organisms, plant roots, detritus and the soil mineral matrix. The nominal oxidation state of carbon (NOSC) has been suggested as a potential parameter for modelling microbial uptake rates of LMWO...

MetabolomicsOral administration of low-molecular-weight heparin ameliorates colitis by enhancing the gut mucus barrier via microbial tryptophan metabolites

Background and Purpose: Previous studies have reported that oral low molecular weight heparin (LMWH) ameliorated colitis by undefined mechanisms in ulcerative colitis (UC) patients. Our study explored the mechanisms of LMWH on colitis from the perspective of gut microbiota and its metabolites.

MetabolomicsA low protein diet drives short and long-term improvements in metabolic health in a mouse model of sleeve gastrectomy

Despite the largely beneficial impact of bariatric surgery on obesity and metabolic disease, many patients continue to suffer from obesity after surgery and weight recurrence is common. The success of bariatric surgery may be impacted by diet. While bariatric surgery guidelines recommend a high-p...

MetabolomicsProtein-metabolite interactomics of carbohydrate metabolism reveal regulation of lactate dehydrogenase

Metabolic networks are interconnected and influence diverse cellular processes. The protein-metabolite interactions that mediate these networks are frequently low affinity and challenging to systematically discover. We developed mass spectrometry integrated with equilibrium dialysis for the disco...

MetabolomicsIntegrated analysis of transcriptome and metabolome reveals molecular responses to ammonia stress in the gills of Litopenaeus vannamei under low-salinity conditions

High ammonia nitrogen stress significantly compromises the survival of Litopenaeus vannamei under low-salinity conditions, posing a common challenge in low-salinity aquaculture. However, existing studies predominantly focus on ammonia nitrogen responses unde...

TranscriptomicsGenome-Wide Expression Profiles in Very Low Birth Weight Infants With Neonatal Sepsis
Bacterial sepsis is associated with high morbidity and mortality in preterm infants. However, diagnosis of sepsis and identification of the causative agent remains challenging. Our aim was to determine genome-wide expression profiles of very low birth weight (VLBW) infants with and without bacterial...

ProteomicsAge-related cleavages of crystallins in human lens cortical fibre cells generate a plethora of low molecular weight peptides and cross-linked crystallin complexes
A large variety of low molecular weight (LMW) peptides, derived from the breakdown of crystallins, have been reported in middle to old age human lenses. The proliferation of these LMW peptides coincides with the earliest stages of cataract formation, suggesting that the protein cleavages involved ma...

ProteomicsA sub-optimal protein precipitation method to improve identification of low molecular weight less abundant proteins
Mass spectrometry-based proteomics studies have enabled identification and quantification of thousands of proteins from biological samples. High molecular weight abundant proteins are readily sampled in global proteomics studies compared to low molecular weight less abundant proteins. Although exten...

MetabolomicsTranscript, protein and metabolite temporal dynamics in the CAM plant Agave
Already a proven mechanism for drought sustainability, crassulacean acid metabolism (CAM) is a specialized type of photosynthesis that maximizes water-use efficiency (WUE) via an inverse (compared to C3 and C4 photosynthesis-performing species) day/night pattern of stomatal closure/opening to shift ...

Proteomics2018CHPP - Digging for Missing Proteins Using Low-Molecular-Weight Protein Enrichment and a "Mirror Protease" Strategy
ABSTRACT Since 2012, Chromosome-Centric Human Proteome Project (C-HPP) launched the journey of missing proteins (MPs) investigation for completing human proteome project (HPP). We found the majority of MPs were distributed in low molecular weight (LMW) ranges, especially in 0-40 kDa. The identificat...
