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’.
