Transcriptome analysis of adult wildtype and pdx1+/- zebrafish kidneys through next generation RNA sequencing

The pdx1 knockout zebrafish mutant has been established as an animal model of diabetic retinopathy. Due to a disturbed beta cell development these mutants develop hyperglycaemia leading to an activation of angiogenesis in the retina of larval and adult stages. This study addresses the questions if the pdx1 heterozygous mutant kidney is also affected by similar changes of the microvasculature and if the expression patterns of signaling pathways and mechanisms associated with the development of diabetic conditions are changed in these kidneys. For this purpose we performed RNA sequencing with the mRNA of total adult kidneys of heterozygous pdx1 mutants and their wildtype littermates. Overall design: RNA expression profiles of adult wildtype and heterozygous pdx1 mutant zebrafish kidneys
