Data from: Net release and uptake of xenometabolites across intestinal, hepatic, muscle, and renal tissue beds in healthy conscious pigs
Data and supplemental figures for manuscript titled "Net release and uptake of xenometabolites across intestinal, hepatic, muscle, and renal tissue beds in healthy conscious pigs." We used a catheterized conscious pig model to estimate inter-organ flux of xenometabolites, derivatives, and bile acids using LC/MS. Female pigs (n=12; 2-3 months old; 25.6 ± 2.2 kg) had surgically-implanted catheters across portal-drained viscera (PDV), splanchnic area (SPL), liver, kidney, and hindquarter muscle. Overnight fasted arterial and venous plasma was collected simultaneously in a conscious state and stored at -80°C. Thawed samples were analyzed by liquid chromatography-mass spectrometry. Plasma flow was determined with para-aminohippuric acid dilution technology and used to calculate net organ balance for each metabolite. This repository contains the LC/MS data and supplemental figures for the submitted manuscript.

Resource Description: Supplemental Figure 1 for Mercer et al manuscript: Supplemental Figure 1: Inter-organ flux of all xenometablites in conscious overnight-fasted female pigs (n=12). A negative flux reflects net uptake (flux < 0; indicated by bottom arrow) by the organ, whereas a positive flux reflects a net release (flux > 0; indicated by top arrow) by the organ. Plasma flow measurements were determined with the para-aminohippuric acid dilution method, and were used along with metabolite concentrations to calculate flux (see Methods). R at top of arrow indicates ‘Release’, while U indicates ‘Uptake’.

Ag Data CommonsIntended use
LC/MS data may be used to estimate inter-organ flux of identified metabolites. The catheterized pig model system is a unique in vivo assessment of organ uptake and release. These data confirm gastrointestinal origin for several microbial derived xenometabolites and suggest that liver and kidneys are uptake sites.Use limitations
Data are observational and do not prove gastrointestinal absorption and do not provide mechanistic information. Only portal, splanchnic, liver, kidney and muscle organs can be assessed in this model, so data cannot rule out release/uptake from other organs. Identified metabolites are based on in-house standard library at the Arkansas Children's Nutrition Center and is not a comprehensive profile of all microbial derived xenometabolites.Theme
