Comprehensive analysis of basement membrane-related genes showed that NELL2 is a new therapeutic target for colorectal cancer.
Article in Discover oncology, 2025. 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
backgroundThe basement membrane (BM), an omnipresent extracellular matrix, plays a pivotal role as a physiological element in the process of tumor metastasis. However, given the heterogeneity of colorectal cancer (CRC), prognosis is challengingly predictive. Therefore, we aim to construct a prognostic model using BM-associated genes to assess patient prognosis and clinical drug treatment effects.
methodThe Non-negative Matrix Factorization (NMF) algorithm leverages the characteristics or categories of matrix rows and columns to achieve BMAG molecular classification and further develop a model for predicting patient prognosis. ssGSEA quantified the relatively abundance of 13 immune functionalities and 16 immune cell typologies. To predict the efficacy of immunotherapy, a comprehensive investigation was conducted on the correlations between riskScores and key factors such as TME, immune checkpoints, and MMR-related genes. The CCK8 method, plate cloning method and Cell Apoptosis Assessment were used to evaluate the ability of NELL2 to affect the proliferation.
resultWe developed a powerful riskScore to predict colorectal cancer prognosis and effectively differentiate the tumor microenvironment. In clinical practice, this riskScore can also be utilized to further assess patient prognosis, thereby facilitating personalized treatment strategies. In addition, downregulation of NELL2 expression inhibits CRC cell proliferation.
conclusionIn summary, we constructed a novel riskScore using BMAG for predicting prognosis in patients with CRC and explored the efficacy of this riskScore in predicting patient response to clinical drug therapy. Most importantly, we have identified the oncogenic role of NELL2 in CRC. By inhibiting NELL2, we can further suppress the initiation and progression of CRC.
