Like most types of cancer, leukemia can be caused by mutations in various genes that regulate cell division, differentiation and apoptosis. In hematological cancers, approximately 30-50 genes have been identified that are recurrently mutated. In individual patients 3-10 mutations may be found that together induce full malignant transformation of blood forming cells leading to leukemia. Different combinations of mutations may be found in different patients, which is associated with a heterogeneous response to therapy and different survival probability. Recently, it was found that also within the tumor, genetic heterogeneity can be detected. In an individual patient, distinct leukemic clones may be present at the same time that share mutations, but also harbor clone-specific aberrations. Preliminary studies have shown that these different clones may respond differently to therapy.
In this project we will study clonal evolution in leukemia and MDS before, during and after therapy using next generation sequencing techniquesThe different subclones will be isolated, and studied for stem-cell characteristics in cellular culture systems, as well as molecular characteristics like gene expression (RNA-seq), and epigenetic alterations (histone modifications and DNA-methylation). Better insight in the genes that cause leukemia, and the effect on clonal expansion and response to therapy should lead to better treatment schedules and better survival rates for these patients. This research will be embedded in the RIMLS research institute and the Radboud Research Theme “Cancer Development and immune Defense”.
