本研究的目的是探讨密蛋白7(CLDN7)在唾液腺腺样囊性癌(SACC)中的表达及其在SACC细胞中的功能。我们通过免疫组织化学和蛋白质印迹测定了 SACC 肿瘤中的 CLDN7 表达,并评估了 CLDN7 表达与临床病理变量之间的关联。除此之外,我们通过RNAi构建了稳定转染的CLDN7敲低SACC-LM细胞系,并评估了其生物学行为变化(细胞活力、迁移和侵袭)。分析CLDN7与上皮间质转化(EMT)之间的相关性。此外,皮下肿瘤形成模型用于评估 CLDN7 敲低后 SACC-LM 细胞的致瘤性。本研究发现肿瘤组CLDN7表达低于正常唾液腺,且与淋巴结转移、复发、性别显着相关。 CLDN7敲低可以通过Wnt/β-catenin信号通路调节EMT来增加SACC的增殖和转移能力。此外,SACC中的CLDN7敲低促进了裸鼠的肿瘤生长。 CLDN7 通过灭活 SACC 中的 Wnt/β-catenin 信号传导来抑制细胞增殖和转移。因此,CLDN7 表达可能是识别 SACC 进展潜力的有用标记。
The aim of this study was to investigate claudin-7 (CLDN7) expression in salivary adenoid cystic carcinoma (SACC) and its function in SACC cells. We determined CLDN7 expression in SACC tumors via immunohistochemistry and western blotting and evaluated the association between CLDN7 expression and clinicopathologic variables. Besides this, we constructed a stably transfected CLDN7 knockdown SACC-LM cell line via RNAi and assessed its biological behavior changes (cell viability, migration, and invasion). The correlation between CLDN7 and epithelial-mesenchymal transition (EMT) was analyzed. Additionally, a subcutaneous tumor formation model was used to assess SACC-LM cells tumorigenicity after the CLDN7 knockdown. In the present study, we found the CLDN7 expression of tumor group was lower than that in normal salivary glands and was significantly correlated with lymph node metastasis, recurrence, and gender. CLDN7 knockdown could add the proliferation and metastasis ability of SACC by regulating EMT through Wnt/β-catenin signaling pathway. In addition, CLDN7 knockdown in SACC promoted tumor growth in nude mice. CLDN7 inhibits cell proliferation and metastasis by inactivating the Wnt/β-catenin signaling in SACC. Thus, CLDN7 expression might be a useful marker to identify the potential for progression in SACC.
