Splice-acceptor site mutation in p53 gene of hu888 zebrafish line.

ABSTRACT: The p53 transcription factor is a key tumor suppressor and a central regulator of the stress response, which has been a subject of intense research for over 30 years. Recently, a zebrafish line which carries splice site mutation (G>T) in intron 8 of p53 gene (p53 (hu888) ), encoding the p53 paralogue, was developed (The Zebrafish Mutation Project). To uncover molecular effects of the mutation, we raised hu888 zebrafish line to adulthood and analyzed DNA, mRNA data, and protein levels of p53 to assess their potential contribution in molecular mechanisms of the mutant fish. To obtain zebrafish individuals homozygous for the point mutation, p53 (hu888) carriers were repeatedly incrossed but only heterozygous mutants (p53 (hu888/+) ) or p53-wild type hu888 zebrafish (p53 (+/+) ) were identifie
