The Emerging Role of CACNA1E in Cancer: Molecular Mechanisms and Therapeutic Implications.
Review in Journal of 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
Voltage-gated calcium channels (VGCCs) are crucial membrane proteins that mediate calcium influx. The CACNA gene family, which encodes the alpha subunits of VGCC complexes, is essential for forming functional calcium channels and plays significant roles in various cancers. This review focuses on the CACNA1E gene, which encodes the Cav2.3 channel α1E subunit, and systematically elaborates its role in cancer. Studies have identified CACNA1E as a key prognostic stemness-related gene in bladder cancer. Its somatic mutations are associated with the development of air pollution-related lung cancer and non-small cell lung cancer. In breast cancer, genetic variations and DNA methylation differences in CACNA1E have also been reported. Functionally, CACNA1E drives tumor progression by regulating calcium signaling. For example, in osteosarcoma, METTL3-mediated m⁶A modification stabilizes CACNA1E mRNA, activating the WNT7B/Ca²⁺ signaling pathway and thereby promoting tumor progression and chemoresistance. The expression of CACNA1E is closely linked to patient prognosis, with its amplification and overexpression correlating with relapse in favorable histology Wilms' tumor. Additionally, CACNA1E is involved in therapy resistance, as evidenced by its downregulation being associated with temozolomide resistance in glioblastoma. Collectively, this evidence suggests that CACNA1E, along with other VGCC members, may serve as a potential prognostic biomarker and therapeutic target in cancer. Future research should further explore their molecular mechanisms, interactions with the tumor microenvironment, and clinical translation potential.
