Osteocytes in the Metastatic Bone Niche: Mechanistic Pathways and Therapeutic Targets.
Review in Pharmaceuticals (Basel, Switzerland), 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
Osteocytes, once viewed mainly as passive bone-embedded cells, are now recognized as active regulators of the metastatic bone niche. Emerging evidence indicates that these cells integrate mechanical, inflammatory, and tumor-derived cues to influence metastatic seeding, dormancy, reactivation, and lesion progression in bone. This review synthesizes current understanding of osteocyte contributions to skeletal metastasis. We discuss core signaling axes, including osteocyte-derived RANKL/OPG balance, Wnt antagonists (sclerostin/DKK1), mechanotransduction pathways (Piezo1 signaling and connexin-43 hemichannels), and osteocyte paracrine mediators (extracellular vesicles and senescence-associated factors), and examine how each axis modulates tumor cell dormancy, osteolysis, or osteoblastic progression. We then review translational strategies targeting osteocytes, recent preclinical and clinical insights. Emerging biomarkers (e.g., serum sclerostin, DKK1, bone turnover markers) and immune-skeletal imaging approaches are also considered. Controversies, including the paradoxical effects of sclerostin blockade and the identity of in vivo RANKL sources, are discussed. Finally, we outline key knowledge gaps and propose endpoints for future trials. In summary, an osteocyte-centric perspective reveals novel targets and strategies for managing bone metastases, guiding future translational research.
