MetabolomicsInteraction of Genetic Variants Activates Latent Metabolic Pathways in Yeast

Genetic interactions are fundamental to the architecture of complex traits, yet the molecular mechanisms by which variant combinations influence cellular pathways remain poorly understood. Here, we answer the question of whether interactions between genetic variants can activate unique pathways a...

MetabolomicsGenetic mapping and molecular mechanism behind color variation in the Asian vine snake

BACKGROUND: Reptiles exhibit a wide variety of skin colors, which serve essential roles in survival and reproduction. However, the molecular basis of these conspicuous colors remains unresolved.

RESULTS: We investigate color morph-enriched Asian vine snakes...

MetabolomicsGain-of-function genetic screens in human cells identify SLC transporters overcoming environmental nutrient restrictions

Solute carrier (SLC) transporters control fluxes of nutrients and metabolites across membranes and thereby represent a critical interface between the microenvironment and cellular and subcellular metabolism. Because of substantial functional overlap, the interplay and relative contributions of SL...

MetabolomicsGenome-wide mapping of genetic suppression events in Streptococcus pneumoniae
Historically, suppressor analysis has been a powerful tool for uncovering the functions of essential genes. In this study, we report Sup-seq, a transposon-sequencing technique with random DNA barcodes that enables genome-wide detection of genetic suppression. When applied to seven essential genes in...

MetabolomicsClock regulation of metabolites reveals coupling between transcription and metabolism
The circadian clock is intricately connected with metabolism, however the precise details of these connections are incomplete. Here we used high temporal resolution metabolite profiling to determine circadian regulation of mouse liver and cell autonomous metabolism. In mouse liver, we found ~50% of ...

MetabolomicsMicroRNA-mediated regulation of lipid metabolism in virus-infected Emiliania huxleyi.
The interactions between Emiliania huxleyi and E. huxleyi virus (EhV) regulate marine carbon and sulfur biogeochemical cycles and play a prominent role in global climate change. As a large DNA virus, EhV has developed a novel 'virocell metabolism' model to meet its high metabolic needs. Although it ...

MetabolomicsMetabolite control of enzyme activity links stress to biosynthetic regulation

Cells must continuously adjust metabolic output to maintain homeostasis under changing environmental conditions, yet the mechanisms that enable rapid and reversible control of pathway activity remain largely unknown. The methylerythritol phosphate (MEP) pathway, of bacterial origin and conserved ...

MetabolomicsPhotosynthetic Carbon Partitioning and Metabolic Regulation in Response to Very-Low and High CO2 in Microchloropsis gaditana NIES 2587
Photosynthetic organisms fix inorganic carbon through carbon capture machinery (CCM) that regulates the assimilation and accumulation of carbon around ribulose-1,5-bisphosphate carboxylase/oxygenase (Rubisco). However, few constraints that govern the central carbon metabolism are regulated by the ca...

MetabolomicsGut microbiota-driven regulation of queen bee ovarian metabolism

With the global prevalence of Varroa mites, more and more beekeepers resort to confining the queen bee in a queen cage to control mite infestation or to breed superior and robust queen bees. However, the impact of such practices on the queen bee remains largely unknown. Therefore, we sub...

MetabolomicsFunctional nutrient-genetic profiling reveals biotin and FBXW7 are essential to bypass glutamine addiction

Metabolic flexibility is key to survival and growth in all living organisms. In mammals, the pathways supporting cell proliferation in nutrient-limiting conditions have not been fully elucidated, although certain tumors display metabolic dependencies that can be targeted for therapy. He...
