Abstract

Pancreatic adenocarcinoma (PAAD) is among the most aggressive malignancies and is associated with poor prognosis due to late diagnosis. This study analyzed RNA-Seq data from TCGA to identify differentially expressed genes (DEGs). A total of 418 DEGs were identified, with enrichment in immune-related processes. Network analysis identified hub genes including PTPN6, which showed significant association with patient survival. These findings highlight potential biomarkers and therapeutic targets.

Introduction

Pancreatic adenocarcinoma is one of the most lethal malignancies with a five-year survival rate below 10%. Advances in transcriptomics have enabled systematic identification of dysregulated genes and pathways. This study aims to identify DEGs and key molecular mechanisms involved in disease progression.

Materials and Methods

RNA-Seq data from TCGA-PAAD were analyzed using Bioconductor tools. Differential expression analysis was performed using glmLRT. Functional enrichment was conducted using ShinyGO, and protein interaction networks were analyzed using STRING and Cytoscape.

Results

A total of 418 DEGs were identified, including 410 upregulated and 8 downregulated genes. Enrichment analysis revealed immune-related pathways. Hub genes such as PTPN6 showed significant clinical relevance.

Discussion

The study highlights the importance of immune-related pathways in pancreatic cancer. PTPN6 was identified as a key prognostic marker, suggesting its potential role in disease progression.

Conclusion

This study provides insights into molecular mechanisms of pancreatic adenocarcinoma and identifies PTPN6 as a potential biomarker and therapeutic target.
