Glucose metabolism and mRNA expression of related metabolic genes in CN-AML patients with low and high PRSs. (A) Heat map showed 6 serum metabolite biomarkers between low and high PRS groups. (B) Heat map showed changes in the expression of genes involved in glucose metabolism of low and high PRS groups. Shades of red and green represented high or low expression (see color scale). Each column represented a patient with low PRS (denoted by deep pink bar) or a patient with high PRS (denoted by deep sky blue bar).
