Although the B-cell translocation gene 1 (BTG1) plays an important role in apoptosis and negatively regulates cell proliferation, BTG1 expression in skin squamous cell carcinoma (SCC) has not been reported. In this study, we wanted to investigate the significance of BTG1 expression in SCC and adjacent tissues. The expression of BTG1 protein and mRNA in SCC tissues and adjacent tissues were detected by immunohistochemistry technique (IHC), Western blot and reverse transcriptase-polymerase chain reaction (RT-PCR). IHC staining showed that the positive expression rate of BTG1 protein in SCC tissues was 54.00%; and the positive rate was 90.50% in the adjacent tissues. Western blot showed that the expression of BTG1 protein in SCC tissues was significantly lower than that in the adjacent tissues (P<0.05). RT-PCR showed that the positive rate of BTG1 mRNA in SCC was 50.50%, which was significantly lower than that in adjacent tissues 89.00% (P<0.05). Both BTG1 mRNA and protein expression are related to tumor diameter, stage, tumor metastasis and the degree of tumor differentiation in SCC. Patients exhibiting lower BTG1 protein expression in the SCC tissues had a significantly shorter disease-specific survival rate. BTG1 protein expression, tumor diameter, tumors site and stage were independent factors affecting the overall survival of postoperative patients. Further, BTG1 overexpression inhibited A431 cell proliferation ability, while BTG silencing enhanced A431 cell proliferation ability. The lower expression of BTG1 in SCC may be associated with the occurrence, development and prognosis of SCC.

B细胞易位基因1(BTG 1)低表达在皮肤鳞状细胞癌中的预后意义

尽管 B 细胞易位基因 1 (BTG1) 在细胞凋亡中起重要作用并负调节细胞增殖,但尚未报道 BTG1 在皮肤鳞状细胞癌 (SCC) 中的表达。在这项研究中,我们想研究 BTG1 在 SCC 和邻近组织中表达的意义。采用免疫组化技术(IHC)、Western blot和逆转录-聚合酶链反应(RT-PCR)检测BTG1蛋白和mRNA在鳞状细胞癌组织及邻近组织中的表达。IHC染色显示BTG1蛋白在SCC组织中的阳性表达率为54.00%;邻近组织阳性率为90.50%。Western blot结果显示,BTG1蛋白在SCC组织中的表达显着低于邻近组织(P<0.05)。RT-PCR显示,SCC中BTG1 mRNA的阳性率为50.50%,明显低于邻近组织的89.00%(P<0.05)。BTG1 mRNA和蛋白表达均与SCC的肿瘤直径、分期、肿瘤转移和肿瘤分化程度有关。在 SCC 组织中表现出较低 BTG1 蛋白表达的患者具有明显较短的疾病特异性存活率。BTG1蛋白表达、肿瘤直径、肿瘤部位和分期是影响术后患者总生存期的独立因素。此外,BTG1 过表达抑制 A431 细胞增殖能力,而 BTG 沉默增强 A431 细胞增殖能力。BTG1在SCC中的低表达可能与SCC的发生、发展和预后有关。显着低于邻近组织的89.00%(P<0.05)。BTG1 mRNA和蛋白表达均与SCC的肿瘤直径、分期、肿瘤转移和肿瘤分化程度有关。在 SCC 组织中表现出较低 BTG1 蛋白表达的患者具有明显较短的疾病特异性存活率。BTG1蛋白表达、肿瘤直径、肿瘤部位和分期是影响术后患者总生存期的独立因素。此外,BTG1 过表达抑制 A431 细胞增殖能力,而 BTG 沉默增强 A431 细胞增殖能力。SCC中BTG1的低表达可能与SCC的发生、发展和预后有关。显着低于邻近组织的89.00%(P<0.05)。BTG1 mRNA和蛋白表达均与SCC的肿瘤直径、分期、肿瘤转移和肿瘤分化程度有关。在 SCC 组织中表现出较低 BTG1 蛋白表达的患者具有明显较短的疾病特异性存活率。BTG1蛋白表达、肿瘤直径、肿瘤部位和分期是影响术后患者总生存期的独立因素。此外,BTG1 过表达抑制 A431 细胞增殖能力,而 BTG 沉默增强 A431 细胞增殖能力。BTG1在SCC中的低表达可能与SCC的发生、发展和预后有关。SCC 的分期、肿瘤转移和肿瘤分化程度。在 SCC 组织中表现出较低 BTG1 蛋白表达的患者具有明显较短的疾病特异性存活率。BTG1蛋白表达、肿瘤直径、肿瘤部位和分期是影响术后患者总生存期的独立因素。此外,BTG1 过表达抑制 A431 细胞增殖能力,而 BTG 沉默增强 A431 细胞增殖能力。SCC中BTG1的低表达可能与SCC的发生、发展和预后有关。SCC 的分期、肿瘤转移和肿瘤分化程度。在 SCC 组织中表现出较低 BTG1 蛋白表达的患者具有明显较短的疾病特异性存活率。BTG1蛋白表达、肿瘤直径、肿瘤部位和分期是影响术后患者总生存期的独立因素。此外,BTG1 过表达抑制 A431 细胞增殖能力,而 BTG 沉默增强 A431 细胞增殖能力。SCC中BTG1的低表达可能与SCC的发生、发展和预后有关。肿瘤部位和分期是影响术后患者总生存期的独立因素。此外,BTG1 过表达抑制 A431 细胞增殖能力,而 BTG 沉默增强 A431 细胞增殖能力。BTG1在SCC中的低表达可能与SCC的发生、发展和预后有关。肿瘤部位和分期是影响术后患者总生存期的独立因素。此外,BTG1 过表达抑制 A431 细胞增殖能力,而 BTG 沉默增强 A431 细胞增殖能力。SCC中BTG1的低表达可能与SCC的发生、发展和预后有关。
