This study aimed to investigate the effect of C15orf48 in non-small cell lung cancer (NSCLC). Bioinformatics analyses were performed using Oncomine, The Cancer Genome Atlas (TCGA), Protein-Protein Interaction (PPI) networks, Gene Ontology (GO), Kyoto Encyclopedia of Genes and Genomes (KEGG), and Gene Set Enrichment Analysis (GSEA). Immunohistochemical staining was used to detect C15orf48 expression in tissue microarrays. Cellular assays, including CCK8, colony formation, wound healing, transwell migration, flow cytometry, and cell adhesion, were conducted to assess cell viability, proliferation, invasion, and apoptosis. A xenograft tumor model was used to examine tumor growth, and Western blotting was used to detect protein expression. C15orf48 expression was significantly upregulated in tumor tissues compared to normal tissues and was associated with poor prognosis. Knockdown of C15orf48 in A549 and H1299 cells reduced proliferation, invasion, and adhesion while increasing apoptosis. C15orf48 knockdown also inhibited tumor growth in vivo and was associated with immune cell infiltration. Although C15orf48 expression correlated with the epithelial-mesenchymal transition (EMT) score, no significant differences were observed. GSEA identified the NF-κB signaling pathway as a key pathway involved. Proteins PLAUR, IKBα, IL-1RN, ICAM1, and TMPRSS4 showed decreased expression in the shC15orf48 group compared to the shCtrl group.

As a result, patients were divided into three groups following the establishment of cut-off values for the neutrophil-to-lymphocyte ratio (NLR) (≥2.53 vs <2.53) and fibrinogen (≥4.55 vs <4.55) through receiver operating characteristic (ROC) curve analysis: F-NLR score 0 (low fibrinogen and low NLR), 2 (high fibrinogen and high NLR), or 1 (remaining patients). The F-NLR score was then identified as an independent risk factor for OS, CSS, and PFS (all P value <0.05) by multivariate regression analysis in both the training and validation cohorts. In addition, F-NLR-based nomograms for OS, CSS, and PFS were developed and evaluated using the concordance index (C-index) and calibration curves. The integration of the F-NLR into existing nomograms improved predictive accuracy compared to the use of nomograms without the F-NLR score.

The biological characteristics and radiosensitivity of EC cells following HYP treatment were evaluated through clone formation experiments, flow cytometry, scratch wound-healing assays, and transwell migration and invasion assays. Western blot analysis was performed to determine the levels of proteins associated with cell death and epithelial-mesenchymal transition (EMT), as well as to explore whether HYP interferes with the radiosensitivity of EC cells via the STAT3/AKT/ERK pathways. Finally, a subcutaneous graft tumor model was constructed to investigate the effects of HYP and X-ray treatments on in vivo tumor growth. The findings indicated a dose-dependent decrease in the survival rate of KYSE-150 and TE-1 cells following HYP treatment. HYP treatment also inhibited cell proliferation, invasion, migration, and EMT, while increasing the apoptotic rate and radiosensitivity of the cells. Notably, HYP suppressed the malignant progression of EC and enhanced radiosensitivity via the STAT3/AKT/ERK pathway. Moreover, HYP impaired the growth of EC tumors in mice, with the combined HYP and X-ray treatment exerting a stronger inhibitory effect.
