YTHDF2 negatively correlates with tumor immune infiltration in small cell lung cancer.
Article in Journal of molecular histology, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. Cited by 4 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
In recent times, RNA modifications have garnered increased attention due to their involvement in the onset and progression of tumors, with N6-methyladenosine (m6A) modification being the most prevalent form. YTHDF2 is an m6A reading protein that can modulate RNA stability, transcription, and translation. This study aimed to explore the role of YTHDF2 in small cell lung cancer (SCLC) by collecting 20 SCLC patients from our hospital (cohort 1) and 48 Chinese SCLC patients from the GEO database (cohort 2). We evaluated the prognostic value of YTHDF2 using Kaplan-Meier survival analysis, Log-rank test, and Cox regression analysis. Additionally, we employed Gene Set Enrichment Analysis (GSEA) to screen different signaling pathways. We also investigated the correlation between the expression of m6A-related genes and SCLC molecular subtype and tumor immune microenvironment (TIME). Furthermore, we utilized multiplex immunofluorescence (mIF) staining to validate the immune infiltration of SCLC patient tissue sections. Our study revealed that YTHDF2 is an independent prognostic factor, which high expression is associated with low overall survival rate in SCLC. Low expression of YTHDF2 in SCLC tumors may enhance the molecular subtype transition from neuroendocrine (NE) to non-neuroendocrine (non-NE) subtype. Low YTHDF2 expression was closely associated with high immune infiltration, immune checkpoints, and other immune-related molecular features. Additionally, mIF detection showed a correlation between the low expression of YTHDF2 and CD4 + T cells and CD8 + T cells. Taken together, YTHDF2 could serve as a potential prognostic biomarker negatively correlated with tumor immune infiltration in SCLC.
