Figure Legend Snippet: Elevated TERF2 expression in AML patients and its correlation with clinicopathological features. (A) Transcriptional expression of TERF2 in AML analyzed using TCGA database. (B) TERF2 mRNA levels quantified by qRT-PCR in PBMCs from 50 AML patients and 35 healthy donors. (C) UMAP of single cells from an AML patient ( GSE116256 ), single-cell profiling reveals distinct expression patterns of TERF2 across cellular subpopulations in AML. (D) Heatmap depicting the average expression level of TERF2 across distinct cell types within the AML sample. (E) Univariate Cox proportional hazards regression analysis comparing survival outcomes between high- and low-TERF2 expression groups. (F) Prognostic accuracy of TERF2 evaluated using ROC curve analysis. (G) The predictive performance of the novel risk stratification model was evaluated through time-dependent ROC curve analysis, with AUC values calculated at 1-, 3-, and 5-year intervals to quantify sensitivity and specificity in AML prognosis. ***, P<0.001; ****, P<0.0001.
