Environmental Enrichment Increases Radiation-induced Apoptosis Not Spontaneous Apoptosis in Mouse Intestinal Crypt Cells.
Article in In vivo (Athens, Greece). The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers, 1 of them a synthesis that pooled 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.
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
BACKGROUND/
aimAn enriched environment (EE) modifies apoptotic cell death and promotes cell proliferation in the central nervous system (CNS) in mice. However, few studies have examined the effects of an EE on apoptosis in non-CNS organs in model orgamisms. In addition, the intestinal tract is one of organs at high-risk of carcinogenesis after radiation exposure. Herein we evaluated the effects of an EE on spontaneous and radiation-induced apoptosis in intestinal crypt cells of mice. MATERIALS AND
methodsJuvenile (3-week-old) and adult (11-week-old) male B6C3F1 mice were housed in a standard environment or EE for 8 weeks and then were whole-body irradiated with 2 Gy X-rays. Apoptosis in the small intestine and colon was analyzed with antibody against cleaved caspase 3.
resultsThe EE significantly reduced body weight; adipose tissue weight; and serum levels of total cholesterol, triglyceride, leptin, and insulin. Although EE did not change the spontaneous apoptotic index without irradiation, it significantly increased the index after irradiation in the colonic crypt. The apoptotic index in the small intestinal crypt showed similar patterns.
conclusionAn EE enhances radiation-induced apoptosis of stem/progenitor cells in the small intestine and colon without affecting spontaneous apoptosis. An EE may thus reduce the risk of cancer in the intestinal tract after radiation exposure such as radiotherapy.
