Abstract
- Acutemyeloidleukaemia(AML) is an illness of varied origin and unpredictable prognosis. Pyroptosis, a novel class of gasdermin-mediated programmed cell death (PCD), serves a critical function in anti-leukemia. But, the correlation between pyroptosis-related genes (PRGs) and AML prognosis is undetermined. Here, we obtained the RNA profile and matched clinical information of AML patients from the TCGA and GEO databases. 6 PRGs were identified to be strongly related to AML prognosis via univariate COX analysis. Next, the LASSO regression analysis was used to develop a PRG signature for AML prognosis, which was then employed for the stratification of patients into a low- (LR) or high-risk (HR) group. Kaplan-Meier analysis revealed that the HR group, but not the LR group, had worse prognosis. In addition, ROC curve analysis revealed that our prognotic model had good predictive value. Functional enrichment analysis indicated that the immune status was remarkably different between the two risk groups. In vitro experiments demonstrated that pyroptosis serves an essential function in anti-leukemia treatment. In summary, our newly developed model has good predictive value and can offer guidance into the precise estimation of AML prognosis and targeting pyroptosis is a potential therapeutic alternative for AML.
