Clinical significance of peroxiredoxin 2 in esophageal squamous cell carcinoma and its role in cell proliferation and apoptosis <i>in vitro,/i>
Abstract
Purpose: To evaluate the expression of peroxiredoxin 2 (PRDX2) and its clinical significance in esophageal squamous cell carcinoma (ESCC) and its effect on the proliferation and apoptosis of ESCC cells.
Methods: The expression of PRDX2 in clinical tissues (120 samples of tumor tissues compared to 20 samples of non-tumor tissues) was determined. The tissues were divided into high-expression group (n = 56) or low-expression group (n = 64) based on the level of PRDX2. Association between PRDX2 expression and clinicopathological features of patients was further analyzed. In vitro, si-NC and si- PRDX2 were transfected into ECA-109 cells, respectively, to determine the influences of PRDX2 on the function of ESCC cells. Quantitative real-time polymerase chain reaction (qRT-PCR) was used to determine the different expressions of PRDX2 in the clinical tissues.
Results: The results from qRT-PCR indicated that PRDX2 was upregulated in ESCC tissues compared to normal control. Correlation between the expression of PRDX2 and clinical pathological data revealed that the expression of PRDX2 showed correlation with tumor differentiation, size, and clinical tumor node metastasis (TNM) stage. Modulation of PRDX2 expression by transfecting si-PRDX2 in ESCC cell lines demonstrated effective regulation of cell proliferation and apoptosis. Specifically, it was observed that cell proliferation decreased, while cell apoptosis was increased.
Conclusion: Peroxiredoxin 2 is a novel factor that plays a significant role in ESCC progression, and constitutes a potential biomarker and therapeutic target for ESCC.
