Janine Ilagan received a postdoctoral fellowship from the Chromosome Metabolism and Cancer Training Grant. Janine proposed to determine how mutations affecting the protein components of the spliceosome contribute to blood disorders, including leukemias. Recently, RNA splicing factors were identified as common mutational targets in myelodysplastic syndromes and related disorders. These mutations directly implicate RNA splicing factors in tumorigenesis, but their functional consequences are unknown. Janine is determining how these mutations alter the normal roles of splicing factors, ultimately contributing to dysplastic hematopoiesis.
