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

Butyrate (BT) is one of the main end products of anaerobic bacterial fermentation of dietary fiber within the human colon. Among its recognized effects, BT inhibits colon carcinogenesis. Our aim was to characterize uptake of BT by two nontransformed intestinal epithelial cell lines: rat small intestinal epithelial (IEC-6) and fetal human colonic epithelial (FHC) cells. Uptake of ¹⁴C-BT by IEC-6 cells was (1) time- and concentration-dependent; (2) pH-dependent; (3) Na+-, Cl⁻- and energy-dependent; (4) inhibited by BT structural analogues; (5) sensitive to monocarboxylate transporter 1 (MCT1) inhibitors; and (6) insensitive to DIDS and amiloride. IEC-6 cells express both MCT1 and Na+-coupled monocarboxylate transporter 1 (SMCT1) mRNA. We conclude that ¹⁴C-BT uptake by IEC-6 cells mainly involves MCT1, with a small contribution of SMCT1. Acute exposure to ethanol, acetaldehyde, indomethacin, resveratrol and quercetin reduced ¹⁴C-BT uptake. Chronic exposure to resveratrol and quercetin reduced ¹⁴C-BT uptake but had no effect on either MCT1 or SMCT1 mRNA levels. Uptake of ¹⁴C-BT by FHC cells was time- and concentration-dependent but pH-, Na+-, Cl⁻- and energy-independent and insensitive to BT structural analogues and MCT1 inhibitors. Although MCT1 (but not SMCT1) mRNA expression was found in FHC cells, the characteristics of ¹⁴C-BT uptake by FHC cells did not support either MCT1 or SMCT1 involvement. In conclusion, uptake characteristics of ¹⁴C-BT differ between IEC-6 and FHC cells. IEC-6 cells demonstrate MCT1- and SMCT1-mediated transport, while FHC cells do not.
