半胱天冬酶1(CASP1)是一种编码多种与细胞死亡相关的蛋白质的基因。然而,CASP1在AML发病机制中的作用仍不清楚。在本研究中,对癌症与正常样本进行了详细分析,以探讨CASP1与白血病之间的关系。我们使用来自多个癌症基因数据库的测序数据来分析CASP1在白血病中的基因表达和调控网络。我们发现CASP1的mRNA表达水平在白血病细胞系中增加,特别是在急性髓细胞白血病(AML)中。然后,我们验证了CASP1在AML临床样本中的mRNA表达,并观察到CASP1在复发AML患者中的表达显著升高。CASP1高表达与预后不良相关,CASP1抑制可损害AML细胞的增殖。相关功能网络的鉴定表明,CASP1通过涉及林恩、LCK和E2F家族的途径调节细胞凋亡、免疫和炎症反应。这些发现表明CASP1可能参与了AML的发病机制,并确定CASP1作为预测AML患者预后的因素和作为治疗靶点。
Caspase1 (CASP1) is a gene that encodes multiple proteins related to cell death. Nevertheless, the function of CASP1 in the pathogenesis of AML is still unclear. In the present study, a detailed analysis of cancer versus normal samples was performed to explore the relationship between CASP1 and leukemia. We used sequencing data from multiple cancer gene databases to analyze the gene expression and regulatory network of CASP1 in leukemia. We discovered that mRNA expression levels of CASP1 are increased in leukemia cell lines, especially in acute myelocytic leukemia (AML). Then, we verified the mRNA expression of CASP1 in AML clinical samples and observed significantly higher expression of CASP1 in relapsed AML patients. High CASP1 expression was associated with poor prognosis and CASP1 inhibition could impair the proliferation of AML cells. Related functional network identification suggests that CASP1 regulates apoptosis, immune and inflammatory response via pathways involving LYN, LCK, and the E2F family. These findings suggest that CASP1 probably contributes to the pathogenesis, and identify CASP1 as a factor for predicting the prognosis and as a therapeutic target of AML patients.
