We hypothesize that piRNAs exhibit oncofetal expression patterns and may contribute to lung cancer development. Through bioinformatics analysis, we identified distinct piRNA profiles in non-neoplastic, malignant, and fetal lung tissues. Among these, 37 piRNAs in LUAD and 46 piRNAs in LUSC displayed oncofetal expression, meaning they were present in tumor tissues but absent in adjacent normal lung tissue. These oncofetal piRNAs showed significant prognostic value in both LUAD and LUSC cohorts, with a specific signature of eight oncofetal piRNAs predicting high-risk patients in LUAD. We validated the robustness of this signature in a separate in-house cohort, which underscores its potential as a prognostic biomarker.

The expression data of circRNAs and mRNAs in endometrial tissues of IUA and normal controls were analyzed by RNA sequencing, and microRNAs (miRNAs) expression data was downloaded from GSE165321. Our analysis identified 44 differentially expressed (DE) circRNAs, 41 DEmiRNAs, and 640 DEmRNAs. A comprehensive circRNA-miRNA-mRNA network was constructed using Cytoscape.

A protein-protein interaction network for ceRNA-associated mRNAs was developed through the STRING database, highlighting potential hub genes.
