CD34 and chronic myelogenous leukemia, BCR-ABL1 positive: To investigate transcription patterns related to the extended G1-phase observed in CP CML progenitors, Integrated System for Motif Activity Response Analysis (ISMARA) was completed on reads from CD34+ CP CML (n = 3) and NP (n = 3) samples subjected to RNA-seq and aligned to the GRCh37 reference genome using STAR (https://github.com/alexdobin/STAR).
