Hybrid Biosilica Nanoparticles for in-vivo Targeted Inhibition of Colorectal Cancer Growth and Label-Free Imaging.
Article in International journal of nanomedicine, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 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: Metastasis-initiating cells are key players in progression, resistance, and relapse of colorectal cancer (CRC), by leveraging the regulatory relationship between Transforming Growth Factor-beta (TGF-β) signaling and anti-L1 cell adhesion molecule (L1CAM). Methods: This study introduces a novel strategy for CRC targeted therapy and imaging based on the use of a hybrid nanosystem made of gold nanoparticles-covered porous biosilica further modified with the (L1CAM) antibody. Results: The nanosystem intracellularly delivers galunisertib (LY), a TGF-β inhibitor, aiming to inhibit epithelial-mesenchymal transition (EMT), a process pivotal for metastasis. Anti-L1CAM antibody-functionalized nanoparticles (NPs) target tumor-initiating cells expressing L1CAM, inhibiting cancer growth. The number of antibody molecules conjugated to the single NP is precisely quantified, revealing a high surface coverage that facilitates the tumor targeting. The therapeutic efficacy of the nanosystem is investigated in organoid-like cultures of CRC cells and in vivo mouse models, showing a significant reduction in tumor growth. The spatial distribution of NPs within CRC tumors from mice is investigated using a label-free optical approach based on Raman micro-spectroscopy. Conclusion: This research highlights the multifunctional capabilities of engineered biosilica NPs, which offer new insights in targeted CRC therapy and imaging, improving patient outcomes and paving the way for personalized therapies.
