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

The biological properties of polyunsaturated fatty acid (PUFA) classes have been the source of much contention. For example, n-3 PUFA are chemoprotective, whereas n-6 PUFA may promote tumor development. Since dietary components can have combinatorial effects, we further examined the apoptotic properties of n-3 or n-6 fatty acids when combined with different fiber sources. Mice were fed diets supplemented with either fish oil (FO; enriched in n-3 PUFA) or corn oil (CO; enriched in n-6 PUFA) and nonfermentable (cellulose) or fermentable (pectin) fiber sources. In complementary experiments, immortalized young adult mouse colonic (YAMC) cells were treated with docosahexaenoic acid (DHA; 22:6n-3) or linoleic acid (LA; 18:2n-6) with or without butyrate. Mice fed a FO and pectin diet had significantly (p < 0.05) increased levels of apoptosis in colonocytes compared to all other diets. Similarly, apoptosis was highly induced in DHA and butyrate cotreated YAMC cells. In contrast, in both YAMC and mouse models, LA/CO with butyrate/pectin treatment reduced apoptosis and enhanced expression of bcl-2. The LA and butyrate induced antiapoptotic phenotype was reversed by knocking down bcl-2 using targeted siRNA. In comparison, overexpression of bcl-2 blocked the proapoptotic effect of DHA and butyrate. These data provide new mechanistic insights into the regulation of apoptosis by dietary PUFA and fiber.
