Correlation of NAT10 expression with clinical data and survival profiles in esophageal squamous cell carcinoma patients, and its impact on cell proliferation and apoptosis.

BACKGROUND: This study investigates the association between NAT10 expression and clinical parameters while assessing prognostic outcomes in esophageal squamous cell carcinoma (ESCC) patients. Furthermore, the study seeks to elucidate the functional role of NAT10 in neoplastic cell proliferation and apoptosis.

MATERIALS AND METHODS: NAT10 expression was assessed in ESCC tissue microarrays through immunohistochemistry (IHC) tests. We employed SPSS software to analyze the correlation between NAT10 staining data, clinical indicators, and their implications for patient prognosis. Small interference RNA (siRNA) was utilized to inhibit NAT10 expression in two esophageal cancer cell lines, TE-1 and KYSE150. Subsequently, we meticulously quantified and compared cellular proliferation and apoptotic ratios among experimental groups. NAT10, Ki67, and Caspase3 expression levels in different groups were evaluated using quantitative polymerase chain reaction (qPCR) and Western blot (WB) assays. Statistical analyses were conducted using GraphPad Prism software, with significance at p <0.05.

RESULTS: Our findings indicate that NAT10 is overexpressed in ESCC tissues and exhibits a significant correlation with tumor diameter and overall patient survival. Decreasing NAT10 expression led to the inhibition of tumor cell proliferation and the promotion of apoptosis. Furthermore, siRNA-mediated NAT10 inhibition resulted in the downregulation of Ki67 expression and the concomitant upregulation of Caspase3.

CONCLUSION: The observed overexpression of NAT10 in ESCC tissues is associated with larger tumor diameters and reduced patient survival. NAT10 appears to play a pivotal role in the progression of esophageal cancer by influencing cell proliferation and apoptosis. These findings suggest potential clinical implications, with Ki67 and Caspase3 potentially participating in this intricate molecular biological process.
