Trx knockdown in intestinal stem cells (ISCs) of Drosophila melanogaster

Male flies were crossed to virgins of genotype yw;esg-Gal4,UAS-GFP;tub-Gal80ts/Tm3,Sb. Progeny was collected and aged 3-4 days before shifting for 7 days to 29 degrees to induce RNAi expression. Guts were dissected for 2 biological replicates/condition, each containing 80-100 guts, dissociated and GFP-positive cells were FACS-sorted. RNA was isolated using the PicoPure RNA-isolation kit and libraries were generated. Sequencing was done by distributing the 4 libraries over 5 lanes on the Illumina HiSeq2000 platform. Two biological replicate samples for each of two groups before and after siRNA knockdown of Trx.
