To investigate 4-TU labelling kinetics in a novel zebrafish transgenic line (lf:UPRT). [Adult SLAM-Itseq]

To understand 4-TU labelling kinetics in a novel zebrafish transgenic line (lf:UPRT), we exposed adult lf:UPRT zebrafish (whereby animals have hepatocyte-specific uracil phosphoribosyltransferase expression) with 4-TU for 1, 3, 6 and 9 hours. We then dissected adult livers for SLAM-ITseq to determine the optimal 4-TU labelling time in our SLAM-ITseq workflow to allow us to study hepatocyte-specific nascent transcriptional changes. Comparative gene expression profiling analysis of SLAM-ITseq data for lf:UPRT animals exposed to 4-TU for different durations.
