Abstract
ETS1, a member of the large ETS domain family of transcription factors, plays a role in the progression of many types of carcinoma. ETS1 expression has been linked to a more favorable prognosis in renal cell carcinoma. The objective of this study was to assess the predictive significance of ETS1 in individuals suffering from clear cell renal cell carcinoma (ccRCC). The correlation between ETS1 expression and ccRCC was analyzed. Data on ETS1 and clinical information for ccRCC patients were obtained from the Cancer Genome Atlas database and analyzed using R software. Then, we presented validation results using RT-qPCR (quantitative reverse transcription PCR). The receiver operator characteristic (ROC) curves were generated using the pROC software package to determine the cutoff values for ETS1. Additionally, the ImmuneScore, StromalScore, and ESTIMATEScore were calculated using the ESTIMATES algorithm. The connection between ccRCC and ETS1 was investigated using enrichment analysis based on Gene Oncology and the Kyoto Encyclopedia of Genes and Genomes. The tumor immunity estimation resource (TIMER) and the integrated repository portal for tumor-immune system interactions (TISIDB) databases were utilized to analyze the association between ETS1 expression and immune cell infiltration in ccRCC. The impact of ETS1 on the survival of ccRCC patients was evaluated using the PrognoScan database. We evaluated the Tumor Mutation Burden (TMB) value between the two sets of samples with high and low ETS1 expression, as well as the differences in gene mutations between the two groups. The mRNA expression of ETS1 in ccRCC was higher compared to normal tissues. Results showed a significant positive correlation between elevated ETS1 expression levels and improved overall survival (OS), disease-specific survival (DSS), and progression-free survival (PFS), with a P < 0.05. Furthermore, high ETS1 expression levels were closely linked to early tumor stage and prolonged survival time. TMB in the ETS1-high expression group was significantly less than that in the ETS1-low expression group. Downregulation of ETS1 expression correlated with poor prognosis and immune infiltration in ccRCC, further suggesting that ETS1 may be a biomarker for better prognosis in ccRCC patients.
