GLUT5, GLUT7, and GLUT11 expression and Bcl-2/Bax ratio on Breast Cancer Cell Line MCF-7 Treated with Fructose and Glucose.
Article in Asian Pacific journal of cancer prevention : APJCP, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
objectiveFructose and glucose are types of sugars commonly found in the diet that have been linked to cancer development. Glucose transporters (GLUTs) are facilitating the uptake of these hexoses. Expression of GLUT5 is higher in cancer cells than in healthy tissue. GLUT7 and GLUT11 facilitate the transport of glucose and fructose; however, their expression in breast cancer has not been extensively studied. The Bcl-2 family has been known as a regulator of the cell's survival and death. Here, we investigated the effect of the fructose-glucose combination in MCF-7 breast cancer cells on the viability, migration, and expression of GLUT5, GLUT7, GLUT11, and Bcl-2/Bax ratio.
methodsBreast cancer cells MCF-7 were treated with fructose, glucose, and combinations of fructose:glucose (75%:25%, 50%:50%, 25%:75%). Cell viability was assessed using an MTT test. Cell migration was examined with a wound-healing assay. Reverse transcription-quantitative polymerase chain reaction (RT-qPCR) was performed to evaluate the mRNA expression of GLUT5, GLUT7, GLUT11, and Bcl-2/Bax.
resultsThe viability and migration of MCF-7 breast cancer cells elevated when treated with a combination of fructose and glucose, and glucose alone, compared to fructose alone. The expression levels of GLUT5 and GLUT7 were highest in combination of fructose:glucose (75%:25%). Conversely, the expression of GLUT11 was consistently low across all treated media. The highest Bcl-2/Bax ratio was shown in fructose:glucose combination (25%:75%).
conclusionThe viability, migration, and Bcl-2/Bax ratio are enhanced in the combination media with higher glucose. In contrast, when the fructose composition was higher in the media, expression of GLUT5 and GLUT7 increased.
