Lentinan inhibits colorectal cancer stemness by binding CD133 and suppressing the CD133/p85/p-AKT signaling axis.
Article in Frontiers in pharmacology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
Background: Colorectal cancer (CRC) ranks third in the global cancer incidence rate worldwide. Cancer stem cells (CSCs) are key drivers of CRC recurrence, metastasis, and therapy resistance, while therapies against them remain limited. Lentinan is widely recognized for its strong immune-enhancing and broad-spectrum directly antitumor activities, however, whether it has potential for cancer stemness remains unknown. Methods: The CRC cell lines HCT116 and SW620 were selected for pharmacodynamic investigation. Furthermore, tumor sphere formation and limiting dilution assays were used to assess the impact of SLNT on stemness of CRC. Using cell sorting alongside cluster of differentiation 133 (CD133) knockdown and overexpression experiments, the key molecular targets of SLNT in exerting anti-CRC effects were identified. To further elucidate the underlying molecular mechanism, we performed localized surface plasmon resonance (LSPR), cellular thermal shift assay (CETSA), and molecular docking simulations. Additionally, western blot analysis was conducted to validate the key signaling molecules involved. Results: Our results demonstrated that lentinan significantly suppressed the proliferation and stemness of CRC cell lines HCT116 and SW620. We identified CD133 as a critical functional target and confirmed a direct binding interaction between lentinan and CD133. Finally, we revealed that lentinan suppresses stemness by inhibiting the CD133/ phosphatidylinositol 3-kinase 85 kDa regulatory subunit (p85)/ phosphorylated AKT serine/threonine kinase (p-AKT) signaling axis in CRC. Conclusion: Our findings not only shed new light on the anti-tumor mechanism of lentinan, highlighting the scientific potential of natural polysaccharides in cancer treatment, but also offers new options for the clinical drug therapy of CRC.
