摘要: 目的 探讨肝细胞癌(HCC)组织中E2F转录因子8(E2F8)、蛋白激酶D1(PKD1)表达与临床病理特征、上皮间质转化(EMT)及预后的关系。方法 选取2018年10月至2021年10月保定市第二医院收治的89例原发性肝癌患者,取术中切除的癌组织和癌旁组织标本,采用免疫组化法检测E2F8、PKD1蛋白以及EMT相关指标(上皮钙黏蛋白、N-钙黏蛋白、波形蛋白)。E2F8、PKD1蛋白表达与EMT相关指标的相关性采用Spearman相关性分析。不同E2F8、PKD1蛋白表达HCC患者生存曲线采用Kaplan-Meier法绘制,Cox比例风险模型分析患者预后的影响因素。结果 与癌旁组织相比,癌组织E2F8蛋白(59.55% vs. 33.71%)、PKD1蛋白(52.81% vs. 25.84%)、N-钙黏蛋白(69.66% vs. 34.83%)、波形蛋白(65.17% vs. 30.34%)的阳性表达率增高(P<0.05);上皮钙黏蛋白(25.84% vs. 66.29%)的阳性表达率降低(P<0.05)。E2F8、PKD1蛋白表达与分化程度、CNLC分期、血管侵犯有关(P<0.05)。CNLC分期Ⅲa期、低分化、发生血管侵犯的HCC组织中,E2F8、PKD1蛋白阳性表达率更高(P<0.05)。HCC组织E2F8、PKD1蛋白表达与上皮钙黏蛋白表达呈负相关,与N-钙黏蛋白、波形蛋白表达呈正相关(P<0.05)。E2F8、PKD1蛋白阳性表达患者3年总生存率低于E2F8、PKD1蛋白阴性表达患者(45.28% vs. 60.61%、44.68% vs. 58.97%,P<0.05)。CNLC分期Ⅲa期、E2F8蛋白阳性表达、PKD1蛋白阳性表达是HCC患者预后不良的危险因素(P<0.05)。结论 HCC组织中,E2F8、PKD1蛋白阳性表达率增高与恶性临床病理特征及EMT密切相关,是患者预后不良的危险因素。

Abstract: Objective To investigate the relationship between E2F transcription factor 8 (E2F8) and protein kinase D1 (PKD1) expressions in hepatocellular carcinoma tissues and clinicopathological features, epithelial-mesenchymal transition (EMT) and prognosis. Methods 89 patients with primary liver cancer were admitted to Baoding Second Hospital from October 2018 to October 2021 were selected. The specimens of cancer tissues and adjacent tissues resected during operation were collected. E2F8, PKD1 protein and EMT related indicators [epithelial cadherins (E-cadherin), N cadherin (N-cadherin), vimentin (Vimentin)] were detected by immunohistochemical method. The correlation between E2F8, PKD1 protein expressions and EMT related indicators was analyzed by Spearman correlation analysis. Survival curves of hepatocellular carcinoma patients with different E2F8 and PKD1 protein expressions were drawn by Kaplan-Meier method, and the prognostic factors of patients with primary liver cancer were analyzed by Cox proportional risk model. Results Compared with adjacent tissues, the positive expression rates of E2F8 protein (59.55% vs. 33.71%), PKD1 protein (52.81% vs. 25.84%), N-cadherin protein (69.66% vs. 34.83%) and Vimentin protein (65.17% vs. 30.34%) in cancer tissues were increased (P<0.05), and the positive expression rates of E-cadherin protein (25.84% vs. 66.29%) were decreased (P<0.05).The E2F8 and PKD1 protein expressions were related to the degree of differentiation, CNLC stage and vascular invasion (P<0.05). The positive expression rates of E2F8 and PKD1 proteins in hepatocellular carcinoma tissues of CNLC stage Ⅲa, low differentiation and vascular invasion were higher (P<0.05). E2F8 and PKD1 protein expressions in primary liver cancer tissues were negatively correlated with E-cadherin protein,positively correlated with N-cadherin and Vimentin protein (P<0.05). The 3-year overall survival rate of patients with E2F8 and PKD1 protein positive expression was lower than those of patients with E2F8 and PKD1 protein negative expression (45.28% vs. 60.61%, 44.68% vs. 58.97%; P<0.05). CNLC stage Ⅲa, positive E2F8 protein expression and positive PKD1 protein expression were risk factors for poor prognosis in hepatocellular carcinoma patients (P<0.05). Conclusion The increased positive expression rates of E2F8 and PKD1 proteins in hepatocellular carcinoma are closely related to malignant clinicopathological features and EMT, which are risk factors for poor prognosis of hepatocellular carcinoma patients.
