A proteomic view of butterfly morphogenesis

ABSTRACT: Insect metamorphosis is one of the most fascinating developmental processes in the natural world. Complete metamorphosis requires the breakdown and re-organization of larval tissues, and the coordinated construction and development of adult structures. The molecular events that achieve this transformation are however incompletely understood, and there is in particular a shortage of data describing changes in protein abundance that occur during the metamorphic journey. Here we provide data from a proteomic analysis of consecutive developmental stages of a laboratory butterfly as it develops from a caterpillar into an adult via pupation. This provides a dynamic reference dataset representing 2749 detected proteins. Statistical analysis identified 90 proteins changing significantly in abundance during metamorphosis, and functional interpretation highlights cuticle formation, apoptosis and autophagy during the pupal stages, and the up-regulation of respiration and energy metabolism upon emergence of the fully formed adult. A search for peptide phosphorylation modifications in the data identified three proteins with roles in muscle function suggesting developmental stage-dependent phosphorylation events.

Project description:To adapt to its changing dietary environment, the digestive tract is extensively remodeled from the embryo to the adult during vertebrate development. Xenopus laevis metamorphosis is an excellent model system for studying mammalian gastrointestinal development and is used to determine the genes and signaling programs essential for intestinal development and maturation. The metamorphosing intestine can be divided into four distinct developmental time points and these were analyzed with X. laevis microarrays. Due to the high level of conservation in developmental signaling programs and homology to mammalian genes, annotations and bioinformatics analysis were based on human orthologs. Clustering of the expression patterns revealed co-expressed genes involved in essential cell processes such as apoptosis and proliferation. The two largest clusters of genes have expression peaks and troughs at the climax of metamorphosis respectively. Novel conserved gene ontology categories regulated during this period include transcriptional activity, signal transduction, and metabolic processes. Interestingly, the induced genes associated with metamorphic climax correlated with the gene expression peaks observed around birth in the mouse intestine. Thus both mouse and amphibian, share similarities at the molecular levels for intestinal maturation and remodeling, which appears to be under the influence of increasing levels of circulating thyroid hormone. Moreover, our genome-wide analysis of the intestine during development identified larval/embryo- and adult-specific genes. Detailed analysis revealed 17 larval specific genes that may represent molecular markers for human colonic cancers, while many adult specific genes are associated with dietary enzymes. This global developmental expression study provides the first detailed molecular description of intestinal remodeling and maturation during postembryonic development, which should help improve our understanding of intestinal organogenesis and human diseases. This study significantly contributes towards our understanding of the dynamics of molecular regulation during development and tissue renewal, which is important for future basic and clinical research and for medicinal applications. Time series experiment through natural metamorphosis of intestine in Xenopus laevis. Biological replicates: 3 replicates for each stage of major change during amphibian metamorphosis (except in the climax where 2 bioogical replicates were used). Universal reference design was used instead of dye-swap design for 2-color hybridizations.
