| Summary |
Introduction Our previous study demonstrated that myc, mitochondrial oxidative phosphorylation, mTOR, and stemness were independently responsible for chemoresistance in AML. The current study aimed to further identify the potential mechanisms of chemoresistance of the “7+3” induction in AML using a single-cell RNA sequencing (scRNA-seq) approach. Methods Thirteen untreated de novo AML patients were enrolled and stratified into the complete remission (CR) (n = 8) and the non-CR (n = 5) groups. We used scRNA-seq to analyze the genetic profiles of 28950 AML cells from these 13 patients. A previously published bulk RNA-seq dataset validated our results. Results Chemoresistant AML cells had more premature accumulation in early hematopoiesis. The hematopoietic stem cell-like cells from the non-CR group expressed more leukemic stem cell markers (CD9, CD82, IL3RA and, IL1RAP) than those from the CR group. Besides, chemoresistant progenitor cells had impaired myeloid differentiation due to early hematopoiesis arrest. Importantly, the AML cells analyzed by the scRNA-seq and bulk RNA-seq honored comparable myeloid lineage cell fraction, which internally validated our results. Using the TCGA database, our analysis demonstrated that AML patients with a higher expression of chemoresistant genetic markers (IL3RA and IL1RAP had a worse overall survival (p < 0.01 for IL3RA; p < 0.05 for IL1RAP).
