We next applied the RNA‐seq data to identify the cell cycle‐related genes that are involved in the cell cycle progression of BCP‐ALL cell lines and identified 10 genes, including HDAC2, CDC23, YWHAG, MAD2L1, CCNH, ANAPC7, CDC6, ANAPC5, ORC3, and RBX1, which were positively correlated with cell cycle progression. The gene discussed is CCNH; the disease is acute lymphoblastic leukemia.
