A short bout of HFD promotes long-lasting hepatic lipid accumulation


Chiazza, Fausto; Challa, Tenagne D; Lucchini, Fabrizio C; Konrad, Daniel; Wueest, Stephan (2016). A short bout of HFD promotes long-lasting hepatic lipid accumulation. Adipocyte (Philadelphia), 5(1):88-92.

Abstract

A short bout of high fat diet (HFD) impairs glucose tolerance and induces hepatic steatosis in mice. Here, we aimed to elaborate on long-lasting effects of short-term high fat feeding. As expected, one week of HFD significantly impaired glucose tolerance. Intriguingly, recovery feeding with a standard rodent diet for 8 weeks did not fully normalize glucose tolerance. In addition, mice exposed to a short bout of HFD revealed significantly increased liver fat accumulation paralleled by elevated portal free fatty acid levels after 8 weeks of recovery feeding compared to exclusively chow-fed littermates. In conclusion, a short bout of HFD has long-lasting effects on hepatic lipid accumulation and glucose tolerance.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
