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

backgroundThe low general toxicity against tumors expressing globotriaosylceramide (Gb3) and Shiga-like toxins produced by E. coli have been proposed as an anti-cancer therapy because of their specific target. This study aimed to determine the potency of the local strains of E. coli O157:H7 isolated from humans and cattle as a new breast cancer therapy by analyzing the cell cycle's inhibition and apoptosis induction. MATERIAL AND

methodsApproximately 10 cultured T47D cells were subjected to Shiga-like toxin produced by four local isolates of E. coli O157:H7, including KL-48 (2) from humans, and SM-25 (1), SM-7 (1), DS-21 (4) from cattle. Using ATCC 43894 as a control, the treatment was observed for 24 h by two replications. In addition, a FITC-Annexin V and PI assay were used to observe apoptosis and necrosis effect, as well as to analyze the cell cycle using propidium iodide (PI) staining.

resultsThe results showed the toxicity effect of Shiga in the human T47 D cells line. The viability of the cells is subjected to Shiga-like toxins produced by KL-48 (2), SM7 (1), ATCC 43894, SM-25 (1), and DS-21 (4) isolates decreased with 15.20, 16.36, 22.17,  22.64, and 33.86%, in contrary to control of 94.36%. These were supported by the cells entering the late apoptosis of the cell cycle through each isolate with 67.66, 62.60, 63.68, 63.90, and 54.74%, and a control of 0.01%. Also, the necrosis cell for each treatment of 12.73, 19.3, 10.84, 10.53, and 4.86% was higher than the control of 5.51%. These were confirmed by the higher percentage of the cells treated with toxins of KL-48 (2), SM7(1), ATCC 43894, SM-25 (1), and DS-21 (4), which entered G0-G1 of the cell cycle phase with 66.41, 63.37, 61.52, 55.36, and 47.28%, respectively, than control of 40.69%. Additionally, the toxicity effect was supported by an increase in the cells entering the S and the G2-M phase of the cycle for each treatment.

conclusionIt is concluded that the Shiga-like toxin produced by E. coli O157:H7 local isolates can be developed as a drug against breast cancer based on its effect to arrest induction of the cell cycle and inducing apoptosis.
