Aberrant sialic acid metabolism promotes metabolic reprogramming and metastasis in breast cancer.

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: Dysregulated tumour metabolism is increasingly recognised as a central driver of malignant phenotypes. Against this background, the aberrant metabolism of N-acetylneuraminic acid (Neu5Ac), a core constituent of the sialic acid family, and its impact on breast cancer progression is now receiving significant research attention. Methods: The purpose of this study is to employ metabolomic approaches to analyze and interpret differences in metabolite profiles connected to breast cancer. Following this, a comprehensive multi-omics analysis will be employed to reveal the differences at transcriptional and metabolic levels in cells after the addition of external sialic acid. Finally, modification proteomics will be applied to recognize and characterize proteins that have different sialylation patterns. Results: Cells treated with sialic acid showed improved motility, underwent metabolic reprogramming, and experienced a significant rise in the sialylation levels of key proteins. Conclusion: This study collectively elucidates the role of Neu5Ac metabolism in promoting breast cancer invasion and metastasis through the remodeling of lipid metabolic pathways and alterations in protein sialylation. The findings present novel evidence supporting the targeting of sialic acid metabolism and its modifications as potential therapeutic strategies for inhibiting tumor progression.
