RNA-Seq of Notch-stimulated overgrowing Drosophila melanogaster wing imaginal discs

ABSTRACT: Aim: mRNA profile of larval wing imaginal discs of Drosophila melanogaster to study the cooperation between Notch activation and loss of epithelial polarity (scrib mutation) during neoplastic growth. Results: The combination of Notch activation and scribble mutation (NS) results in mRNA expression changes that, while partly overlapping with Notch only (N), and with scrib mutation only (S), are unique to the combination

Su(H) ChIP-on-chip of Notch-stimulated overgrowing Drosophila melanogaster wing imaginal discs

Project description:Aim: Su(H) chromatin occupancy profiling by ChIP on larval wing imaginal discs of Drosophila melanogaster to study the cooperation between Notch activation and loss of epithelial polarity (scrib mutation) during neoplastic growth. Results: The combination of Notch activation and scribble mutation (NS) does not lead to a general redeployment of Su(H) binding as compared to individual conditions (Notch only (N), and scrib mutation only (S))

Single-cell RNA sequencing of Drosophila wing discs harboring the scrib mutant clones in combination with RasV12, YkiS168A or NAct signals.

Project description:It has long been proposed that cell competition functions to remove precancerous clones. A classical model is the removal of polarity-deficient clones such as the scribble (scrib) mutant clones in Drosophila imaginal discs. The activation of Ras, Yki or Notch signaling robustly reverses the scrib mutant clonal fate from elimination to tumorous growth. Using single-cell transcriptomics techniques to profile wing imaginal discs harboring the scrib mutant clones in combination with different signals, we found that a critical converging point downstream of Ras, Yki and Notch signals is the upregulation of Upd2, which is necessary to promote tumorous growth. Unexpectedly, while Upd2 is not required for cell survival per se, Upd2-deficient clones are efficiently wiped out from epithelia, indicating that Upd2 is a previously unrecognized cell competition factor.

Single-cell transcriptomic analysis of the scrib mutant 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.

Quantitative Analysis of Wild Type and scrib mutant Drosophila wing imaginal discs Transcriptomes at different time points

Project description:Purpose: There are two goals of this study. Firstly, we want to figure out the transcriptomic differences between control and scrib¹ mutant wing imaginal discs. Secondly, we aim to investigate the transcriptomic changes as the scrib¹ mutant tumor develop over time. Methods: Total RNA was used to generate cDNA libraries and 150bp paired-end sequencing on Illumina HiSeq platform were performed by Novogene. Cleaned raw reads were mapped to the reference genome using STAR and counts are generated by featuresCounts available in Subread package. Count normalization was performed using edgeR.

RNA-seq of Drosophila melanogaster wing imaginal discs during L3 stage

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.

Genome -wide profile of SMRTER binding in Drosophila wing imaginal discs

Project description:Several co-repressors interact directly with the DNA-binding protein CSL [Su(H) in Drosophila] and are proposed to keep target genes silenced in the absence of Notch activity. To investigate co-repressor activity in the context of this well defined signalling pathway, we analysed the genome-wide binding profile of the best-characterized CSL co-repressor in Drosophila, Hairless, in Kc cells and in wing imaginal discs. The binding profile in wing discs of a second CSL interacting repressor, SMRTER, was also analysed. There was significant overlap between Hairless and Su(H), both in Kc cells and in wing discs, where they were predominantly found in chromatin with active enhancer marks. The Hairless complex was widely present at some Notch regulated enhancers in the wing disc,but no binding was detected at others, indicating that it is not essential for silencing per se. Analysis of target enhancers confirmed differential requirements for Hairless. SMRTER binding significantly overlapped with Hairless, rather than complementing it, and many enhancers were apparently co-bound by both factors. Our analysis indicates that the actions of Hairless and SMRTER gate the enhancers to Notch activity and to Ecdysone signalling respectively, to ensure that the appropriate levels and timing of target gene expression are achieved.
