Correction to: Cichorium intybus L. promotes intestinal uric acid excretion by modulating ABCG2 in experimental hyperuricemia

Correction to: Nutrition & Metabolism (2017) 14:38 https://doi.org/10.1186/s12986-017-0190-6

Following the publication of the original article [1], errors were identified in the Abstract, Tables 1 and 2, and Figure 3.

The sentence currently reads:

These findings indicate that chicory increases uric acid excretion by intestines, which may be related to the stimulation of intestinal uric acid excretion via down-regulating the mRNA and protein expressions of ABCG2.

The sentence should read:

These findings indicate that chicory increases uric acid excretion by intestines, which may be related to the stimulation of intestinal uric acid excretion via up-regulating the mRNA and protein expressions of ABCG2.

The original article [1] has been corrected.

Low expression of model group in jejunum and ileum (P < 0.05, P < 0.01 vs. control group slices), which developed heavy stains; inhibition of ABCG2 by chicory (P < 0 .01, P < 0 .01 vs. model group slices)
