Lactylation in cancer: a new frontier in metabolic-epigenetic regulation and clinical practice.
Review in Cell communication and signaling : CCS, 2026. 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
The discovery of lysine lactylation (Kla) redefines lactate from a passive glycolytic by-product into a bioactive metabolic mediator that directly links cellular metabolism to epigenetic regulation. This emerging post-translational modification dynamically alters histone and non-histone proteins, thereby reconfiguring gene expression programs and immune responses within the tumor microenvironment (TME). It consequently promotes core malignant phenotypes including uncontrolled proliferation, epithelial-mesenchymal transition (EMT), metastatic dissemination, and resistance to chemotherapy, radiotherapy, and immune checkpoint blockade. Specific epigenetic signatures, notably histone H3K18la and H4K12la marks, serve as transcriptional anchors for oncogenic pathways across multiple cancer types. Multi-omics analyses have further yielded Kla-associated gene profiles with the potential to refine prognostic stratification and drug-target identification. These findings establish Kla as a central axis in tumor-associated metabolic-epigenetic crosstalk. Effective clinical application of KLAsKla biomarkers requires resolving technical detection limits and addressing the spatiotemporal heterogeneity that currently constrains machine learning-based prognostic models. Overcoming these bottlenecks is contingent upon leveraging advanced technologies such as single-cell multi-omics and spatial transcriptomics. This review characterizes the emerging roles of Kla in tumor metabolism, providing a framework for its future application as a diagnostic and therapeutic cornerstone in precision oncology.
