Project description:During the last larval stage (L3) of Drosophila melanosgaster development, wing imaginal discs undergo tremendous growth and initiate differentiation programs. This transcriptomic time course aims at uncovering the the genes that are temporally regulated during the L3 in wing imaginal discs to regulate the dynamics of growth and differentiation.
Project description:We report the changes in chromatin accessibility associated with regeneration in wing imaginal discs at two developmental timepoints during L3. Wing discs were ablated using tissue-specific expression of the pro-apoptotic gene eiger at an early timepoint (day 7) when the discs retain high regenerative capacity and at a late time point (day 9) when regenerative capacity has significantly declined. ATAC-seq was performed on these discs after 40 hr of ablation and compared to identically staged unablated discs. We detect 14,142 open chromatin peaks after merging overlapping peaks from 3 biological repeats of all 4 conditions. Of these, 349 change significantly (log2fc>0.5, p<0.1) either opening or closing upon damage in early L3 discs, while only 55 open or close in late L3 discs. We describe two consequential groups of peak changes, those that are damage responsive (DR) in early L3 (222 peaks) and those that are maturity silenced (MS), open in early damaged L3 and closed in late damaged L3 (729 peaks). 28 peaks fall in the overlap of these two groups.
Project description:Screening for binding partners of the splicing factor SmD3 and changes in interaction upon depletion of the protein Ecdysoneless (Ecd) in the nubbin domain of third-instar larval wing imaginal discs.
Project description:Two pcm null alleles (pcm14 and pcm15) were sequenced alongside respective wild-type controls (wild-type 1 and wild-type 2). Each genotype was replicated 3 times. Read depth was 12-17 million reads per replicate. Total RNA was prepared from Drosophila L3 larval wing imaginal discs.
Project description:Investigation of intratumor heterogeneity in the scrib¹ mutant wing imaginal discs. Method: Staged scrib¹ wing imaginal discs were dissected and transferred to DPBS. The wing imaginal discs were dissociated in 0.25% Trypsin-EDTA solution at 37 ℃ for 10 min. Cells were then washed in DPBS and passed through 35μm filter before library preparation. Construction of 10x single cell libraries and sequencing on Illumina platform were performed by Novogene.
Project description:We investigated the effect on mRNA expression in Drosophila melanogaster wing imaginal discs following the knockdown of the 3'-5' exoribonuclease Dis3L2.
Project description:We investigated the effect on miRNA expression in Drosophila melanogaster wing imaginal discs following the knockdown of the 3'-5' exoribonuclease Dis3.
Project description:We report here the transcriptomic analysis of Drosophila melanogaster wing imaginal discs from third instar female larvae mutant for corto (cortoL1/corto420) The reference line was the w1118 genetic background of the mutant lines.
