摘要
研究目的本研究旨在探讨ADAM12（A disintegrin and metalloproteinase domain 12）在结直肠癌（CRC）组织和细胞中的表达和调控机制：下载并分析 TCGA 和 GSE68468 数据集中 ADAM12 的表达水平。收集重庆大学江津医院2017年4月至2019年12月的石蜡保存标本，通过免疫组化检测ADAM12的表达。利用结直肠癌细胞株（SW480、HCT116）进行细胞实验，选择ADAM12高表达的细胞进行沉默实验，利用CCK-8检测细胞增殖能力，利用划痕实验和Transwell侵袭实验检测各组细胞的迁移能力。用 Western blot 检测 EMT 标记（E-cadherin、N-cadherin、Vimentin、Twist）和 Wnt/β-catenin 标记（β-catenin、GSK-3β、p-GSK-3β、C-MYC、MMP-7）。我们构建了裸鼠 CRC 肿瘤模型，并通过免疫组化和 Western blot 验证了 ADAM12 对 EMT 和 Wnt/β-catenin 的影响：生物信息学研究表明，ADAM12表达的增加与患者的预后密切相关。免疫组化显示，ADAM12的升高与血管侵犯（p < 0.05）、神经侵犯（p < 0.01）、淋巴结转移（p < 0.01）和TNM分期（p < 0.001）相关。细胞功能实验显示，ADAM12过表达组增强了CRC细胞的增殖和迁移。过表达 ADAM12 后，N-cadherin、Vimentin 和 Twist 的表达增加，而 E-cadherin 的表达减少（p < 0.01）。Wnt/β-catenin相关蛋白：β-catenin、p-GSK-3 β、C-MYC和MMP-7的表达增加（p < 0.01），而Wnt/β-catenin抑制剂MSAB能对抗ADAM12对CRC细胞EMT的影响。裸鼠皮下肿瘤形成实验结果表明，与对照组相比，ADAM12能促进肿瘤生长并诱导EMT：结论：ADAM12的过表达通过Wnt/β-catenin信号轴控制CRC的EMT，从而促进肿瘤的侵袭和转移。
The Emerging Role of ADAM 12 Regulates Epithelial-mesenchymal Transition by Activating the Wnt/β-catenin Signaling Pathway in Colorectal Cancer.
Objective: The objective of this study is to investigate the expression and regulatory mechanisms of A disintegrin and metalloproteinase domain 12 (ADAM12) in colorectal cancer (CRC) tissues and cells.
Methods: Download and analyze the expression levels of ADAM12 in the TCGA and GSE68468 datasets. Collect paraffin-preserved specimens from the Chongqing University Jiangjin Hospital from April 2017 to December 2019 and detect the expression of ADAM12 through immunohistochemistry. Cell experiments were conducted using colorectal cancer cell lines (SW480, HCT116), and cells with high expression of ADAM12 were selected for silencing experiments, and cell proliferation ability using CCK-8, and migration ability of cells in each group using scratch assay and Transwell invasion assay. The EMT markers (E-cadherin, N-cadherin, Vimentin, Twist) and the Wnt/β-catenin markers (β-catenin, GSK-3β, p-GSK-3β, C-MYC, MMP-7) were detected using western blot. We construct a nude mouse CRC tumor model and validate the effect of ADAM12 on EMT and Wnt/β-catenin through immunohistochemistry and Western blot.
Results: Bioinformatics showed that increased expression of ADAM12 was strongly correlated with patient prognosis. Immunohistochemistry showed that elevated ADAM12 was associated with vascular invasion (p < 0.05), neurological invasion (p < 0.01), lymph node metastasis (p < 0.01), and TNM staging (p < 0.001). Experiments on cell function revealed that the ADAM12 overexpression group augmented CRC cells' proliferation and migration. After overexpression of ADAM12, the expression of N-cadherin, Vimentin, and Twist increased, while the expression of E-cadherin decreased (p < 0.01). The expression of Proteins related to Wnt/β-catenin: β-catenin, p-GSK-3 β, C-MYC and MMP-7 increased (p < 0.01), and Wnt/β-catenin inhibitor MSAB can counteract the effect of ADAM12 on EMT in CRC cells. The subcutaneous tumor formation experiment results in nude mice showed that ADAM12 promoted tumor growth and induced EMT compared to the control group.
Conclusion: ADAM12 overexpression through the Wnt/β-catenin signal axis controls the EMT of CRC to promote invasion and metastasis.
