Loss of Antp function in Drosophila flight muscle precursors : RNAi in larval wing disc-associated myoblasts

Project description:Muscle development and diversity require a large number of spatially and temporally regulated events controlled by transcription factors (TFs). Drosophila has long stood as a model organism to study myogenesis due to the highly conserved key TFs involved at all stages of muscle development, from specification to differentiation. While many studies focused on the diversification of Drosophila larval musculature, how distinct adult muscle types are generated is much less characterised. Here, we identify a novel essential regulator of Drosophila thoracic flight muscle development, the Hox TF Antennapedia (Antp). Correcting a long standing misconception that flight muscle development occurs without the input of Hox TFs, we show that Antp intervenes at several stages of adult flight muscle development, from the establishment of the progenitor pool in the embryo to myoblast differentiation in the early pupa. Furthermore, the precisely regulated clearance of Hox at the pupal stage in the developing indirect flight muscle fibers is required to allow for stretch-activated fibrillar muscle fate diversification that sets these flight muscles apart from all other adult tubular muscle types.

Wing imaginal disc spatial expression

Project description:Wing imaginal discs were dissected to generate body wall and wing/hinge fragments. Targets from three biological replicates of each were generated and the expression profiles were determined using Affymetrix Drosophila Genechip 1 arrays. Comparisons between the sample groups allow the identification of genes with localized expression patterns. Keywords = Drosophila, wing disc, spatially restricted transcripts Keywords: repeat sample

Single-cell transcriptomics of the Drosophila wing disc reveals instructive epithelium-to-myoblast interactions

Project description:In both vertebrates and invertebrates, generating a functional appendage requires interactions between ectoderm-derived epithelia and mesoderm-derived cells. To investigate such interactions, we used single-cell transcriptomics to generate a temporal cell atlas of the Drosophila wing disc from two developmental time points. Using these data, we visualized gene expression using a multi-layered model of the wing disc and catalogued ligand-receptor pairs that could mediate signaling between epithelial cells and adult muscle precursors (AMPs). We found that localized expression of the FGF ligands, Thisbe and Pyramus, in the disc epithelium regulates the number and location of the AMPs. In addition, Hedgehog ligand from the epithelium activates a specific transcriptional program within adjacent AMP cells, defined by AMP-specific targets Neurotactin and midline, that is critical for proper formation of direct flight muscles. More generally, our annotated temporal cell atlas provides an organ-wide view of potential cell-cell interactions between epithelial and myogenic cells.

Gene expression changes in Su(H) induced wing disc hyperplasia

Project description:The outcome of Notch activation of proliferation depends on cellular context. In Drosophila wing discs Notch pathway overactivation results in hyperplasia. To understand the mechanisms we have used genomic strategies to indetify the Notch-S(H) target genes directly regulated in wing disc hyperplasia. These data are the results from expression profiling the RNAs from hyperplastic wing discs overexpressing Su(H). Direct comparison of Giant third instar lavae wing imaginal disc (UAS-GFP:Su(H) expressed by the patched[559.1]-Gal4 driver) vs control (UAS-NLS-GFP expressed by the patched[559.1]-Gal4 driver). 3 Biological replicates, the 3rd replicate was performed as a dye-swap.

Su(H) bound regions in Nicd induced wing-disc hyperplasia

Project description:The outcome of Notch activation on proliferation depends on cellular context. In Drosophila wing discs Notch activation causes hyperplasia despite having localized inhibitory effects on proliferation. To understand the underlying mechanisms we have used genomic strategies to identify the Notch-Su(H) target genes directly activated during wing disc hyperplasia. These data are the results from ChIP-Chip experiments to identify genomic regions occupied by Su(H) in hyperplastic Nicd-expressing Drosophila wing discs.
