Regulation of Keratin Chemical Modifications: Potential Molecular Mechanisms in Proliferative Diseases.
Review in International journal of molecular sciences, 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
Keratin, a core structural protein in epithelial cells, is essential for maintaining epithelial tissue integrity. Numerous studies have confirmed its critical role in proliferative disorders, including lung/liver cancer, idiopathic pulmonary fibrosis (IPF), and hepatic fibrosis (HF). Post-translational modification (PTM) regulates protein activity, and keratin undergoes phosphorylation, acetylation, and methylation-modifications that modulate fibrosis and cancer progression by regulating relevant signaling pathways. However, how these modifications reshape keratin's structure and function in these diseases remains understudied, underscoring the necessity for a systematic review. This review first summarizes keratin's classification, physiological functions, and roles in epithelial cells, then focuses on the physiological significance of keratin modifications in fibrosis and cancer, while dissecting the molecular mechanisms by which keratin PTMs drive disease progression to address the knowledge gap regarding modification-related keratin changes. Elucidating the mechanisms of keratin and its PTMs is pivotal for understanding disease progression and developing targeted therapies; meanwhile, keratin-targeted strategies-such as keratin siRNAs and small-molecule compounds that regulate keratin expression or modification-have shown therapeutic potential. In summary, this review synthesizes current research findings and provides novel insights for the treatment of fibrosis and cancer.
