Dual role of lncRNA OTUD6B-AS1 in immune evasion and ferroptosis resistance: A prognostic and therapeutic biomarker in breast cancer.

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: Long non-coding RNAs (lncRNAs) have emerged as pivotal regulators in tumorigenesis and therapeutic resistance. This study investigates the prognostic significance and dual biological functions of lncRNA OTUD6B-AS1 in breast cancer (BC), focusing on its roles in immune evasion and ferroptosis resistance. Methods: Multi-omics data from The Cancer Genome Atlas (TCGA), Gene Expression Omnibus (GEO), and lncRNA databases (AnnoLnc2, LncACTdb 3.0) were integrated to analyze OTUD6B-AS1 expression, clinical relevance, and molecular networks. Experimental validations included co-culture assays with CD8 Results: OTUD6B-AS1 exhibited significant overexpression across multiple cancers, particularly in breast cancer (BC), where elevated levels strongly correlated with poor prognosis. Its expression was closely associated with key clinical indicators (T/N/M stage, ER/PR/HER2 status), prompting the development of a nomogram prognostic model with high clinical applicability. Genomic analysis revealed frequent amplification of OTUD6B-AS1 and co-occurrence of PIK3CA mutations. Co-expression and ceRNA networks highlighted its interaction with RNA degradation pathways. Notably, OTUD6B-AS1 was associated with immune evasion by regulating PD-L1 and CD8 Conclusion: In conclusion, OTUD6B-AS1 serves as a biomarker in BC, driving immune evasion and ferroptosis resistance. Targeting OTUD6B-AS1 may enhance immunotherapy efficacy and overcome chemoresistance, offering novel therapeutic avenues.
