MetabolomicsSerum protein N-glycosylation changes in multiple myeloma

BACKGROUND: Multiple myeloma is characterized by clonal proliferation of malignant plasma cells in the bone marrow that produce monoclonal immunoglobulins. N-glycosylation changes of these monoclonal immunoglobulins have been reported in multiple myeloma, but previous studies on...

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...

MetabolomicsPROMIS, global analysis of PROtein-Metabolite Interactions using Size separation in Arabidopsis thaliana
Small molecules not only represent cellular building blocks and metabolic intermediates, but also regulatory ligands and signaling molecules that interact with proteins. Although these interactions affect cellular metabolism, growth, and development, they have been largely understudied. Herein, we d...

MetabolomicsThe patatin-like protein PlpD forms novel structurally dynamic homodimers in the Pseudomonas aeruginosa outer membrane

Members of the Omp85 superfamily of outer membrane proteins (OMPs) found in Gram-negative bacteria, mitochondria and chloroplasts are characterized by a distinctive 16-stranded β-barrel transmembrane domain and at least one periplasmic POTRA domain. All previously studied Omp85 proteins promote c...

MetabolomicsIntegrating two chromatographies in a co-fractionation mass spectrometry approach improved protein-metabolite interactions (PMIs) mapping capabilities and revealed novel protein-ligand pairings in Escherichia coli.
The protein-metabolite interactome remains understudied. We previously developed a co-fractionation mass-spectrometry-based approach called PROMIS to address this gap. PROMIS relies on size separation chromatography of protein-metabolite complexes from lysates, followed by proteomics and metabolomic...

MetabolomicsThe Bardet-Biedl protein Bbs1 controls photoreceptor outer segment protein and lipid composition

Summary

Primary cilia are key sensory organelles whose dysfunction leads to ciliopathy disorders such as Bardet-Biedl syndrome (BBS). Retinal degeneration is common in ciliopathies, since the outer segments (OSs) of photoreceptors are highly specialized primary cilia. BBS...

MetabolomicsElevated temperature accelerates leaf senescence and promotes leaf nitrogen transport to improve rice grain protein synthesis
Elevated temperatures during grain filling severely constrain rice yield and quality. Although additional nitrogen can mitigate the adverse effects of elevated temperature, both factors increase grain protein content, and the underlying physiological mechanisms remain poorly understood. Here, we con...

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 ...

Metabolomics1H NMR metabolomic and transcriptomic analyses reveal urinary metabolites as biomarker candidates in response to protein undernutrition in adult rats

BACKGROUND: Protein undernutrition is prevalent mainly among elderly people, and it could develop diseases such as sarcopenia. Urinary metabolites may become biomarkers reflecting protein undernutrition, but this has been insufficiently investigated.

OBJECTIVE:

MetabolomicsOverexpression of vesicle-associated membrane protein PttVAP27-17 as a tool to improve biomass production and the overall saccharification yields in Populus trees

Background

Bioconversion of wood into bioproducts and biofuels is hindered by the recalcitrance of woody raw material to bioprocesses such as enzymatic saccharification. Targeted modification of the chemical composition of the feedstock can improve saccharification but this gain is often abr...
