A The hazard ratios of the LASSO selected 18 genes. B Kaplan–Meier curve for the overall survival (OS) of AML patients classified by the median of Gene-18 risk score. C Receiver-operating characteristic (ROC) curve of the Gene-18 risk score. D Kaplan–Meier curve for the overall survival (OS) of AML patients classified by the Gene-18 risk score in the validated set. E The correlation of circSPI1-regulated 18-gene risk score and circSPI1 expression. F Correlation matrix of circSPI1 and circSPI1-regulated 18 genes. RNA quantification analysis was performed on the transcriptomic data of AML patients with enough sequencing depth that enabled the identification of both linear SPI1 and circSPI1. The Pearson method was used to assess the correlations among circSPI1 and circSPI1-regulated genes. G The correlation of HSPA8 and circSPI1 expression. H Expression levels of HSPA8 were analyzed in AML patients and normal subjects. I Kaplan–Meier curve for the overall survival (OS) of AML patients with high or low HSPA8 expression levels. J HSPA8 was essential for the survival of AML cells. Normalized read counts of sgRNA in AML cells transfected with the CRISPR-cas9/sgRNA library before and after population doublings are shown.
