Appraising histone H4 lysine 5 lactylation as a novel biomarker in breast cancer.
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 10 papers.
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 Posttranslational modifications of histone lysine (K) have integral connections with cell metabolism, and participate in the carcinogenesis of various cancers. This study focuses on evaluating the expression of histone H4 lys 5 lactylation (H4K5lac) and its clinical role in breast cancer (BC). Methods During this research, immunohistochemistry (IHC) and immunoblotting, utilizing a specific primary anti-L-lactyl-histone H4 (Lys 5) rabbit monoclonal antibody, were employed to assess H4K5lac expression in BC tissue chips. H4K5lac expression in the peripheral blood mononuclear cells (PBMCs) of BC patients was investigated through immunoblotting. Results IHC revealed upregulation of histone H4K5lac in both triple-negative breast cancer (TNBC) and non-TNBC tissues, with positive rate of 91.40% [170/(150 + 19 + 17)] and 93.64% (103/110) in TNBC and non-TNBC tissues, respectively. The expression of H4K5lac demonstrated positive correlations with lymph nodes (%), and Ki-67 expression. Survival analysis indicated a negative correlation between H4K5lac expression and overall survival (OS) time in both TNBC (HR [hazard ratio] = 2.773, 95%CI [confidence interval]: 1.128-6.851, P = 0.0384) and non-TNBC cases (HR = 2.156, 95%CI: 1.011-4.599, P = 0.0275). Furthermore, elevated levels of H4K5lac were observed in the PBMCs of BC cases, and H4K5lac expression is positively correlated with serum lactate and carcinoma embryonic antigen (CEA) levels. Conclusions Histone H4K5lac exhibits increased levels in both BC tissues and PBMCs, suggesting its potential as a promising biomarker for BC. This study might pave the way toward novel lactylation treatment strategies in BC.
