摘　　要：目的:探讨半胱氨酸酶抑制剂A(CSTA)在口腔鳞癌中的表达及其与临床病理特征的关系。方法:通过免疫组织化学染色、Western免疫印迹和实时定量PCR(qRT-PCR)检测CSTA的表达,通过Transwell迁移侵袭实验评估CSTA对口腔鳞癌细胞转移的促进作用。采用SPSS 25.0和GraphPad Prism 8.4.3软件进行数据分析。结果:CSTA在口腔鳞癌中的表达显著低于正常口腔黏膜上皮组织,其表达量与颈淋巴结转移(P=0.028)和肿瘤病理级别呈显著负相关(P=0.001),CSTA低表达的细胞倾向分布于肿瘤侵袭前缘;CSTA低表达组患者总生存期显著短于CSTA高表达组,CSTA过表达可在体外抑制口腔鳞癌细胞迁移与侵袭。结论:CSTA在调控口腔鳞癌颈淋巴转移过程中发挥重要作用,有望成为口腔鳞癌颈淋巴转移的潜在预测和治疗靶标。PURPOSE:To evaluate the expression of cystatin A(CSTA)in oral squamous cell carcinoma(OSCC),and its association with clinicopathological factors.METHODS:The expression of CSTA was examined using quantitative realtime PCR,immunohistochemistry,and Western blotting.Statistical analysis was performed to determine the association between CSTA expression and clinicopathological characteristics of patients with OSCC.The effect of CSTA on migration and invasion was evaluated using in vitro assays.The results were analyzed using SPSS 25.0 and GraphPad Prism 8.4.3 software.RESULTS:CSTA expression was significantly downregulated in primary OSCC tissues,and lower CSTA expression was significantly correlated with high tumor grade(P=0.001),cervical lymph node metastasis(P=0.028),and poor overall survival(P<0.001).CTSA overexpression inhibited OSCC cell migration and invasion in vitro.CONCLUSIONS:This study revealed that CSTA is a promising biomarker and therapeutic target with prognostic implications in patients with OSCC.CSTA may play an essential role in cervical lymph node metastasis and tumor differentiation.
