DLK1: a novel therapeutic target in cancer.
Review in Endocrine-related cancer, 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
Abstract: Delta-like non-canonical Notch ligand 1 (DLK1) is a cleavable transmembrane protein with tightly regulated, developmentally restricted expression. It is highly expressed during embryogenesis, where it plays a key role in controlling cellular differentiation and proliferation, but is largely silenced in adult tissues, persisting mainly within stem and progenitor compartments of endocrine organs. Notably, DLK1 is consistently re-expressed across a broad range of malignancies, with the highest prevalence observed in endocrine and neuroendocrine tumours, including adrenocortical carcinoma, phaeochromocytoma/paraganglioma, medullary thyroid carcinoma, and neuroblastoma. DLK1 expression is associated with adverse clinical outcomes and is increasingly implicated in maintaining a de-differentiated, stem-like tumour phenotype that might contribute to tumour progression and therapeutic resistance. The restricted expression of DLK1 in normal adult tissues, combined with its cell-surface localisation and functional relevance in tumour biology, makes it an attractive therapeutic target, particularly in endocrine malignancies where targetable options remain limited. Multiple DLK1-directed strategies are now advancing through preclinical and early clinical development, including afucosylated monoclonal antibodies, antibody-drug conjugates, dendritic cell vaccines, chimeric antigen receptor T-cell therapies, and radioimmunotherapy. Early-phase studies demonstrate encouraging safety profiles and signals of efficacy, with emerging evidence suggesting that tumour-specific factors - such as steroidogenesis, immune microenvironment, and drug efflux mechanisms - may influence response in endocrine cancers. This review collates current evidence on DLK1 biology and therapeutic targeting, with a focus on endocrine and neuroendocrine malignancies. We highlight key novel mechanistic insights, translational challenges, and future opportunities to exploit DLK1 as a precision therapeutic target in these high-need cancer subtypes.
