KDM1A and diffuse large B-cell lymphoma: Kaplan–Meier survival analysis revealed that the KDM1A low expression group (KDM1A-low) had a higher survival rate than that of the KDM1A high expression group (KDM1A-high) based on the data from Genomicscape website (http://www.genomicscape.com/), suggesting that high KDM1A expression in DLBCL tissues was associated with poor prognosis of patients (Fig. 1b).
