PURPOSE
Actin-like 6A (ACTL6A), a regulatory subunit of the ATP-dependent chromatin-remodeling complex SWI/SNF, acts as an oncogenic factor. This study is aimed at evaluating the correlation between ACTL6A expression and clinicopathological parameters in pancreatic cancer (PC) patients.
METHODS
The differences of mRNA expression between PC tissues and normal pancreatic tissues were analyzed in public databases, and ACTL6A expression was then determined and confirmed in 60 paired tissue specimens using immunohistochemistry staining. The association analysis between ACTL6A expression and the clinicopathological characteristics was analyzed, as well as Kaplan-Meier survival analysis. Univariate and multivariate Cox analyses were performed to identify the prognostic factors in the overall survival (OS) of patients with PC.
RESULTS
The mRNA expression of Actl6a showed significantly higher in PC compared to normal controls (p < 0.05) from public databases. The score of immunohistochemistry staining further confirmed that ACTL6A expression was significantly upregulated in PC tissues (p < 0.001) through immunohistochemistry staining. High ACTL6A expression was associated with lymphovascular space invasion of PC. Kaplan-Meier analysis revealed that the high expression of ACTL6A was markedly associated with poor OS. Moreover, univariate and multivariate analysis demonstrated that ACTL6A acted as an independent risk factor for PC prognosis.
CONCLUSION
ACTL6A is upregulated in PC and acts as a risk factor for poor prognosis in patients with PC, and therefore clinicians could around it design preventive measures and individualized treatment to improve mortality in patients with PC.
目的
肌动蛋白样6A(ACTL6A)是ATP依赖性染色质重塑复合体SWI/SNF的一个调节亚基,作为一种致癌因子发挥作用。本研究旨在评估胰腺癌(PC)患者中ACTL6A表达与临床病理参数之间的相关性。
方法
在公共数据库中分析PC组织与正常胰腺组织之间mRNA表达的差异,然后使用免疫组织化学染色在60对组织标本中测定并确认ACTL6A表达。分析ACTL6A表达与临床病理特征之间的关联分析,以及Kaplan-Meier生存分析。进行单因素和多因素Cox分析以确定PC患者总生存期(OS)的预后因素。
结果
来自公共数据库的数据显示,与正常对照相比,PC中Actl6a的mRNA表达显著更高(p < 0.05)。免疫组织化学染色评分进一步证实,通过免疫组织化学染色,ACTL6A在PC组织中的表达显著上调(p < 0.001)。ACTL6A高表达与PC的淋巴血管间隙浸润有关。Kaplan-Meier分析显示,ACTL6A的高表达与较差的OS显著相关。此外,单因素和多因素分析表明,ACTL6A是PC预后的独立危险因素。
结论
ACTL6A在PC中上调,是PC患者预后不良的危险因素,因此临床医生可以围绕它设计预防措施和个体化治疗,以提高PC患者的死亡率。
