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...

MetabolomicsDecreasing peptide deformylase activity is a beneficial strategy for increasing formaldehyde resistance in Methylobacterium extorquens
Formaldehyde is a highly toxic metabolite that can cause extensive damage to DNA and proteins, and strategies to mitigate formaldehyde toxicity are poorly understood. Methylotrophic bacteria, such as Methylobacterium extorquens, thrive on one-carbon compounds as sole sources of carbon and energy. Th...

MetabolomicsMulti-hierarchical profiling the structure-activity relationships of engineered nanomaterials at nano-bio interfaces
Increasing concerns over the possible risks of nanotechnology necessitates breakthroughs in structure-activity relationship (SAR) analyses of engineered nanomaterials (ENMs) at nano-bio interfaces. However, current nano-SARs are often based on univariate assessments and fail to provide tiered views ...

MetabolomicsAntioxidant Activity, Phytochemical Profiling by UPLC-QTOF-MS, and In Silico Targeting of the RNA-Binding Protein DRBD18 of Trypanosoma brucei by Bioactive Compounds from Tetradenia riparia and Tetracera poggei
Oxidative stress plays a key role in the pathogenesis of African trypanosomiasis, and plant-derived antioxidants represent a promising source of dual-action compounds capable of both scavenging reactive oxygen species and interfering with parasite survival. The present study investigates the antioxi...

MetabolomicsMetabolic response to point mutations reveals principles of modulation of in vivo enzyme activity and phenotype
The relationship between sequence variation and phenotype is poorly understood. Here, we use metabolomic analysis to elucidate the molecular mechanism underlying the filamentous phenotype of E. coli strains that carry destabilizing mutations in dihydrofolate reductase (DHFR). We find that partial lo...

MetabolomicsImpact of reproductive activity on physiological metabolism and molecular regulation in the Genus scallopus(Mizuhopecten yessoensis)

Genus scallopus(Mizuhopecten yessoensis), a commercially important shellfish species in China, suffers a persistently high post-spawning mortality rate, severely constraining industry development. Thus, this study investigated the physiological and molecular impact of reproductive activity on M. ...

MetabolomicsTrans-tissue molecular coordination in high-intensity physical activity
High-intensity physical activity has major impacts in different parts of the body. However, the regulatory coordination between different tissues to support the high physical demands is poorly understood. Here we performed a multi-omics analysis of blood plasma, urine and saliva from a group of fire...

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...

MetabolomicsRibosomal mistranslation leads to silencing of the unfolded protein response and increased mitochondrial biogenesis

Translation fidelity is the limiting factor in the accuracy of gene expression. With an estimated frequency of 10-4, errors in mRNA decoding occur in a mostly stochastic manner. Little is known about the response of higher eukaryotes to chronic loss of ribosomal accuracy as per an increase in the...
