Article Mrna Decay Analysis in Drosophila Melanogaster: Drug-Induced Changes in Glutathione S-Transferase D21 Mrna Stability(Academic Press Inc., 2008) Akgül, Bünyamin; Tu, Chen-Pei D.We have established an in vivo system to investigate mechanisms by which pentobarbital (PB), a psychoactive drug with a sedative effect, changes the rate of decay of gstD21 mRNA (encoding a Drosophila glutathione S-transferase). Here we describe methods for the use of hsp70 promoter-based transgenes and transgenic lines to determine mRNA half-lives by RNase protection assays in Drosophila. We are able to identify and map putative decay intermediates by cRT-PCR and DNA sequencing of the resulting clones. Our results indicate that the 3′-UTR of gstD21 mRNA is responsive to PB by regulating mRNA decay and that the cis-acting element(s) responsible for the PB-mediated stabilization resides in a 59 nucleotide sequence in the 3′-UTR of the gstD21 mRNA (Akgül and Tu, 2007).
