MetabolomicsSAR11 Cells Rely on Enzyme Multifunctionality to Transport and Metabolize a Range of Polyamine Compounds
In the ocean surface layer and cell culture, the polyamine transport protein PotD of SAR11 bacteria is often one of the most abundant proteins detected. Polyamines are organic cations at seawater pH produced by all living organisms and are thought to be an important component of dissolved organic ma...

MetabolomicsSalmonella Typhimurium reprograms macrophage metabolism via T3SS effector SopE2 to promote intracellular replication and virulence

Salmonella Typhimurium establishes systemic infection by replicating in host macrophages. Here we show that macrophages infected with S. Typhimurium exhibit upregulated glycolysis and decreased serine synthesis, leading to accumulation of glycolytic intermediates. The effects on...

MetabolomicsSystematic identification of bacterial factors driving Staphylococcus aureus intracellular lifestyle in non-professional phagocytes

Staphylococcus aureus is a major human pathogen responsible for severe infections. While traditionally described as extracellular, increasing evidence establishes S. aureus as a facultative intracellular pathogen. Intracellularity contributes to immune evasion, dissemination, and antibiotic failu...

MetabolomicsApoplastic metabolomics reveals sugars as mesophyll messengers regulating guard cell ion transport under red light
Here we sought to identify mesophyll messenger(s) that promote stomatal opening under red light. We first established a method to isolate leaf apoplastic fluids from Arabidopsis thaliana and Vicia faba and ascertained that the apoplastic fluid enhances red light-induced stomatal opening. We then app...

TranscriptomicsTranscription profiling of peripheral blood or primary finroblast cultures from choroideremia patients to determine if loss-of-function mutations in REP-1 affect intracellular vesicle transport in fibroblasts and monocytes of CHM patients
Choroideremia (CHM) is a progressive X-linked retinopathy caused by mutations in the CHM gene, which encodes Rab escort protein-1 (REP-1), an escort protein involved in the prenylation of Rabs. Under-prenylation of certain Rabs, as a result of loss of function mutations in REP-1, could affect vesicu...

MetabolomicsL-leucine increases the sensitivity of drug-resistant Salmonella to sarafloxacin by stimulating central carbon metabolism and increasing intracellular reactive oxygen species level (LC-MS positive mode)

The overuse of antibiotics has made public health and safety face a serious crisis. It is urgent to develop new clinical treatment methods to combat drug-resistant bacteria to alleviate the health crisis. The efficiency of antibiotics is closely related to the metabolic state of bacteria. However...

TranscriptomicsTransport of influenza A virus neuraminidase to host cell surface and virus replication are regulated by ARHGAP21 and Cdc42
Influenza virus neuraminidase (NA), a type II transmembrane glycoprotein, is transported to the virus assembly site at the plasma membrane and is a major viral envelope component that plays a critical role in the release of progeny virions and in determination of host range restriction. Although sig...

TranscriptomicsTranscription profiling of T. brucei in vivo or in vitro samples, with in vitro samples either inclubated at 4oC or not to investiage the influence of culturing condtions on intracellular transport
The vast majority of molecular studies on T. brucei are carried out using in vitro cultures. Recently, whole-genome microarray analysis indicated significant differences between in vivo and in vitro cultures of the malaria parasite Plasmodium falciparum. Therefore, as an additional investigation int...
