Identification of an Anoikis-Related Gene Signature to Predict the Prognosis in Patients With Oral Squamous Cell Carcinoma.
Article in International dental journal, 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
backgroundAnoikis plays an important role in cancer metastasis. Nevertheless, research that focuses on the prognostic values of anoikis-related genes (ARGs) in oral squamous cell carcinoma (OSCC) is still scarce.
methodsThe ARG-related gene signature was developed via LASSO regression using the TCGA-OSCC cohort. OSCC patients in the TCGA_OSCC and GSE41613 datasets were grouped into high- and low-ARG score (H-score, L-score) groups, and the overall survival (OS) between the 2 groups was analysed. Meanwhile, functional enrichment, CIBERSORT and drug sensitivity were conducted based on the data from the TCGA_OSCC cohort. Loss-of-function assay was employed to explore the biological roles of SPINK1 in OSCC.
resultsIn the current research, we constructed a novel prognostic model based on 5 ARGs (SPINK1, PLAU, VEGFA, PLK1 and EGF) for OSCC. The OS of OSCC patients in the H-score group was worse than that in the L-score group. Moreover, patients with the H-score had low immune and ESTIMATE scores, suggesting a declined immune status in these patients. Additionally, some tumour-promoting signalling pathways (e.g. focal adhesion, PI3K-Akt and WNT signalling pathways) were notably activated in the H-score group. Functionally, downregulation of SPINK1 notably suppressed OSCC cell viability, migration and invasion and induced ferroptosis through inactivation of the Nrf2/GPX4 signalling pathway.
conclusionWe have developed a novel 5-gene signature related to ARG, which may serve as a predictor for OS in patients with OSCC. Our findings may open a new possibility of providing personalised treatment for OSCC patients.
