Abstract:
In previous studies, we have discovered a significant correlation between cGMP-dependent protein kinase I antisense RNA 1 (PRKG1-AS1) and the prognosis of lung adenocarcinoma (LUAD). Through analysis of The Cancer Genome Atlas (TCGA) database and expression data from non-small cell lung cancer tissues and cells, we found that PRKG1-AS1 is overexpressed in LUAD tissues. High expression of PRKG1-AS1 is associated with poor prognosis in LUAD patients. Cox regression analysis revealed that PRKG1-AS1 is an independent factor affecting the prognosis of LUAD. Gene Set Enrichment Analysis (GSEA) results indicated that PRKG1-AS1 might participate in various cancer-related biological processes and signaling pathways, including immune response. Furthermore, our study demonstrated that knockdown of PRKG1-AS1 expression inhibited proliferation and metastasis in LUAD. Correlation analysis between PRKG1-AS1 and protein-coding genes (PCGs) revealed a positive correlation between PRKG1-AS1 and dickkopf-1 (DKK1). Downregulation of PRKG1-AS1 led to decreased expression of DKK1, which is highly expressed in LUAD and is associated with poor prognosis. In summary, our findings suggest that PRKG1-AS1 may function as an oncogene contributing to the development of LUAD and holds significant prognostic value.
