Fig 2. Tissue cytokines are directly correlated with serum percent SFA.

Snap frozen colonic biopsies were lysed and cytokine/chemokine levels were measured by Luminex technology, with each sample corrected for tissue lysate protein concentration, as described in the Methods. Blood was obtained from each subject and processed within 30 min to obtain serum. Serum fatty acid levels were measured as described in the Methods. The Spearman correlation coefficient (r) and the associated P value are shown. n = 58 for UC subjects. There were no significant correlations in control subjects (data not shown).
