Study ID	ST002918
Study Title	Metabolic Profiling in mouse Infected with Vibrio parahaemolyticus
Study Summary	Mice were subject to intraperitoneal (i.p.) injection with the V. parahaemolyticus, and control mice were injected with saline. Data were collected and analyzed using unsupervised hierarchical clustering. In general, the abundance of metabolites increased more often than it decreased in animals with higher resistance to infection. Load weight analysis of biological pathways suggested that alanine, aspartate, glutamate metabolism could play roles in the capacity of mice to survive infection with V. parahaemolyticus.

Project Title:	Exogenous L-Alanine promotes phagocytosis via dual regulations of TLR4 to eliminate multidrug-resistant bacterial pathogens
Project Type:	MS quantitative analysis
Project Summary:	Multidrug-resistant bacteria present a major threat to public health. Therefore, new drugs or approaches are urgently needed to manage and mitigate this threat. Here, we screen the molecular candidates that allow the survival of mice upon multidrug-resistant Vibrio parahaemolyticus infection by integrated proteomic and metabolomics analysis, where L-Alanine metabolism and phagocytosis are highly correlated. The role of L-Alanine on boosting mouse survival is further confirmed with in vivo bacterial challenge studies on multidrug-resistant bacteria including V. parahaemolyticus, Escherichia coli, Pseudomonas aeruginosa, Klebsiella pneumoniae. Functional studies demonstrate that exogenous L-Alanine promotes phagocytosis to these different species of multidrug-resistant pathogens. The underlying mechanism involves two events that are L-Alanine-dependently increased TLR4 expression, and L-Alanine-enhanced TLR4 signaling via increasing the biosynthesis and secretion of fatty acids such as palmitate. Palmitate enhances the binding of LPS to TLR4 and thereby promotes TLR4 dimmer formation and endocytosis for the subsequent activation of PI3K/Akt and NF-κB pathways and phagocytosis of bacteria. These results suggest that modulation of metabolic environment is a plausible approach for combating infection with multidrug-resistant bacteria.

MS Comments:	samples was derivatized and then used to firstly protect carbonyl moieties through methoximation, through a 90 min 37 ℃ reaction with 40 μL of 20 mg/mL methoxyamine hydrochloride (Sigma-Aldrich) in pyridine, followed by derivatization of acidic protons through a 30 min 37 0C reaction with the addition of 80 μL N-methyl-N-trimethylsilyltrifluoroace-tamide (MSTFA, Sigma-Aldrich). The derivatized sample of 1 μL was injected into a 30m × 250 μm i.d. × 0.25 μm DBS-MS column using splitless injection and analysis was carried out by Trace DSQ II (Thermo Scientific). The initial temperature of the GC oven was held at 85 0C for 5 min followed by an increase to 330 0C at a rate of 15 0C min-1 then held for 5 min. Helium was used as carrier gas and flow was kept constant at 1 mL min-1. The MS was operated in a range of 50-600 m/z.
