Zebrafish as a model for study of disorders in pyrimidine nucleotide metabolism

Wang, Liya


Pyrimidine nucleotides are not only the building blocks of DNA and RNA but also participate in multiple cellular metabolic processes, including protein, lipid and polysaccharide biosynthesis. Pyrimidine nucleotides are synthesized by two distinct pathways-the de novo and salvage pathways. Disorders in pyrimidine nucleotide metabolism cause severe neurodegenerative disorders in human. For example, deficiency in thymidylate kinase, an essential enzyme in dTTP synthesis, causes severe microcephaly in human patients. Zebrafish mutants selected by insertion mutagenesis that results in inactive enzymes in pyrimidine metabolism showed also neurological and developmental disorders. In this work I have summarized current data on neurological and developmental disorders caused by defects in enzymes in pyrimidine nucleotide metabolism in zebrafish and compared to human. All these data suggest that zebrafish is a useful animal model to study pathogenic mechanism of neurological disorders due to defect in pyrimidine nucleotide metabolism.
