Anthocyanin Enhances Development, Hatching, and GLUT4 Expression in In Vitro-Cultured ICR Mouse Blastocysts.

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
Anthocyanin is a flavonoid known for its strong antioxidant and anti-inflammatory activities in both in vitro and in vivo systems. This study investigated whether anthocyanin supplementation could improve the developmental competence, hatching rate, and the expression of development- and proliferation-related markers in ICR mouse blastocysts cultured in vitro. Mouse embryos were cultured in KSOM medium supplemented with 2, 4, or 8 μM anthocyanin. Among these, 4 μM was selected as the working concentration within the tested range. Morphological assessment was used to evaluate blastocyst development and hatching, while quantitative real-time polymerase chain reaction (qPCR) was performed to measure the expression of GLUT4 and PI3K. Anthocyanin supplementation significantly enhanced blastocyst quality, as reflected by higher developmental competence and increased hatching rates compared with the control group. In addition, anthocyanin-treated blastocysts displayed elevated mRNA expression of GLUT4 and PI3K, indicating a potential association with enhanced metabolic readiness and cellular proliferation. Overall, these findings indicate that anthocyanin supports embryo quality during preimplantation development in vitro, with potential relevance to implantation-related processes. Further research is needed to clarify the underlying mechanisms and explore the potential applications of anthocyanin in reproductive medicine.
