1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

Early stage estrogen receptor α (ERα, ESR1)-positive breast cancer patients can develop more aggressive endocrine-resistant tumors that express constitutively active mutant forms of ERα including ERα-Y537S and ERα-D538G. These patients are treated with selective ER down regulators (SERDs) such as the ERα antagonist fulvestrant. Previous studies show that histone deacetylase (HDAC) inhibitors downregulate ERα and since some dietary derived short chain fatty acids (butyrate, propionate and acetate) exhibit HDAC inhibitory activity we investigated their effects as SERDs in MCF-7 and T47D cells expressing wild-type and mutant ERα-D538G and ERα-Y537S. The SCFAs exhibited SERD-like activity in both cell lines expressing wild-type and mutant ERα. The results for propionate and butyrate correlated with parallel induction of histone acetylation and this was also observed for the HDAC inhibitors Panobinostat, Vorinostat and Entinostat which also downregulated wild-type and mutant ERα and induced histone acetylation. Although acetate induced ERα degradation the mechanisms may be independent of the HDAC inhibitory activity of this compound. These results suggest that high fibre diets that induce formation of SCFAs may have some clinical efficacy for treating ER-positive endocrine resistant breast cancer patients and this is currently being investigated.
