MetabolomicsCo-occurrence of direct and indirect extracellular electron transfer mechanisms during electroactive respiration in a dissimilatory sulfate reducing bacterium

Understanding the extracellular electron transfer mechanisms of electroactive bacteria could help determine their potential in microbial fuel cells (MFCs) and their microbial syntrophy with redox-active minerals in natural environments. However, the mechanisms of extracellular electron transfer t...

MetabolomicsMultiple roles of extracellular vesicles in promoting microbial driven elemental cycle

Microbial driven manganese (Mn) reduction influences the geochemical cycling of Mn and the environmental fate of various organic and inorganic substances. Extracellular vesicles (EVs) are known to impact microbial metabolic activities, but their specific role in Mn reduction remains arcane. Here,...

MetabolomicsParallel single-cell metabolic analysis and extracellular vesicle profiling reveal vulnerabilities with prognostic significance in acute myeloid leukemia (Metabolomic analysis on extracellular vesicles)

Acute myeloid leukemia (AML) is an aggressive disease with a high relapse rate. In this study, we map the metabolic profile of CD34+(CD38low/-) AML cells and the extracellular vesicle signatures in circulation from AML patients at diagnosis. CD34+ AML cells display high antioxidant glutathione le...

MetabolomicsExtracellular-acidosis restricts one-carbon metabolism and preserves T cell stemness
The accumulation of acidic metabolic waste products within the tumor microenvironment profoundly inhibits effector functions of tumor-infiltrating lymphocytes (TILs). However, it is unclear whether extracellular-acidosis impacts T cell metabolic fitness and differentiation status. Here, we surprisin...

ProteomicsMechanistic insights bidirectional extracellular electron transfer driving synchronous nitrogen fixation in Klebsiella variicola
Microorganisms can function as anode catalysts to achieve biological nitrogen fixation while simultaneously generating bioelectricity. To date, only a limited number of microorganisms are capable of performing both outward and inward extracellular electron transfer (EET) concurrently. However, the v...
