Abstract

Unlabelled Histone-deacetylase (HDAC) -inhibitors enhance acetylation of core proteins and this is linked to formation of transcriptionally active chromatin in various cells. In this study, the effect of HDAC inhibitors (butyrate, trichostatin A (TSA)) on the expression of the cathelicidin LL-37 in colon, gastric and hepatocellular cells was investigated.Methods LL-37 expression was assessed in colon, gastric and hepatocellular cancer cells after treatment with HDAC-inhibitors. In parallel, histone H4 and HMGN2, a non-histone protein, acetylation was evaluated. In addition, the intracellular signalling pathway MEK-ERK was explored.Results In contrast to normal colon epithelial cells, gastrointestinal cancer cells lacked LL-37 expression. LL-37 was induced following treatment with HDAC-inhibitors in all investigated cell lines. This induction was time-dependent in butyrate-treated cells while TSA exerted a transient effect. Induction of LL-37 by butyrate was paralleled by acetylation of the histone H4 and the non-histone HMGN2. Again, TSA resulted in transient acetylation. Furthermore, inhibition of MEK-ERK blocked HDAC inhibitor-induced LL-37 expression in colonic and gastric cells.Conclusions We have previously shown that butyrate induces LL-37 in colon epithelial cells. In the present study, we demonstrate that cathelicidin expression is modulated by HDAC-inhibitors in various gastrointestinal cells including gastric and hepatocellular cells. This is paralleled by changes in the acetylation of distinct core proteins suggesting a common regulatory mechanism of cathelicidin LL-37 regulation in these cells.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
