Interaction of Alkannin with CPEB4 Contributes to Its Antitumor Effects in Melanoma.
Article in Biomolecules, 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
Melanoma is a highly aggressive malignancy characterized by strong invasive and metastatic potential. CPEB4 has been implicated in melanoma progression and may serve as a potential therapeutic target. Alkannin has previously been reported to exert antitumor activity against melanoma; however, its in vivo efficacy and direct molecular interaction with CPEB4 remain unclear. In this study, a subcutaneous xenograft model using BALB/c nude mice was used to assess the in vivo antitumor effects of alkannin, and CPEB4 expression was analyzed via Western blotting. DARTS, CETSA, and SPR investigations were used to elucidate the interaction between alkannin and CPEB4. In addition, stable CPEB4-knockdown A375 melanoma cells were established to examine the effects of alkannin on cell proliferation, apoptosis, cell cycle progression, migration, invasion, and downstream signaling molecules. Alkannin markedly suppressed tumor growth in the xenograft model and reduced CPEB4 expression in a dose-dependent manner compared with the model group. DARTS and CETSA demonstrated alkannin-induced stabilization of CPEB4, while SPR analysis using purified recombinant CPEB4 showed a direct physical interaction with alkannin, with micromolar affinity. At the molecular level, alkannin downregulated CPEB4 and PRC1 expression (
