Study ID	ST002877
Study Title	Metabolic Profiling of Raw264.7 Mouse Macrophage Cells Cultured with Alanine
Study Summary	To identify the catabolites of L-Alanine on promoting phagocytosis, GC-MS based metabolomics analysis was adopted to explore L-Alanine-reprogrammed metabolome. The metabolic flow of the TCA cycle was dysregulated. Meanwhile, six metabolites (oleate, palmitate, stearate, myristate, arachidonate and linoleate) in biosynthesis of saturated and unsaturated fatty acids were increased upon L-Alanine treatment, where palmitate was the biggest absolute increment in abundance. Thus, L-Alanine promotes the biosynthesis of fatty acids.

Treatment:

Treatment ID:	TR002999
Treatment Summary:	To trace L-Alanine metabolism, RAW264.7 cell were grown in DMEM (Hyclone) supplemented with 10% (v/v) cosmic calf (Hyclone), then transferred into L-Alanine-free medium and deprived of serum overnight. Subsequently, cells were incubated with 5 mM L-Alanine and 5mM [U-13C]-L-Alanine in serum-starved medium (DMEM/0.5% serum). Additionally, fresh media containing L-Alanine and [U-13C]-L-Alanine were exchanged 2 h before metabolite extraction for metabolic analysis.
