Transcriptome analysis of the epidermis of the purple quail-like (q-lp) mutant of silkworm, Bombyx mori

Project description:A new purple quail-like (q-lp) mutant found from the plain silkworm strain 932VR has pigment dots on the epidermis similar to the pigment mutant quail (q). In addition, q-lp mutant larvae are inactive, consume little and grow slowly, with a high death rate and other developmental abnormalities. Pigmentation of the silkworm epidermis consists of melanin, ommochrome and pteridine. Silkworm development is regulated by ecdysone and juvenile hormone. In this study, we performed RNA-Seq on the epidermis of the q-lp mutant in the 4th instar during molting, with 932VR serving as the control. The results showed 515 differentially expressed genes, of which 234 were upregulated and 281 downregulated in q-lp. BLASTGO analysis indicated that the downregulated genes mainly encode protein-binding proteins, membrane components, oxidation/reduction enzymes, and proteolytic enzymes, whereas the upregulated genes largely encode cuticle structural constituents, membrane components, transport related proteins, and protein-inding proteins. Quantitative reverse transcription PCR was used to verify the accuracy of the RNA-Seq data, focusing on key genes for biosynthesis of the three pigments and chitin as well as genes encoding cuticular proteins and several related nuclear receptors, which are thought to play key roles in the q-lp mutant. We drew three conclusions based on the results: 1) melanin, ommochrome and pteridine pigments are all increased in the q-lp mutant; 2) more cuticle proteins are expressed in q-lp than in 932VR, and the number of upregulated cuticular genes is significantly greater than downregulated genes; 3) the downstream pathway regulated by ecdysone is blocked in the q-lp mutant. Our research findings lay the foundation for further research on the developmental changes responsible for the q-lp mutant.

Gene expression of abnormal uric acid synthesis animal model of silk worm Bombyx mori.

Project description:Uric acid (UA) is the final product of purine metabolism and plays an important role as a physiological antioxidant. In recent years, several different groups have reported a correlation between decreased UA in Parkinson’s disease (PD) and clinical progression and stage of PD. However, little is known about the molecular mechanisms of decreased UA under oxidative stress. We used our systematic functional annotation pipeline for silkworm genes to identify a novel UA metabolic pathway regulator under oxidative stress in a UA metabolism mutant silkworm Bombyx mori model. Gene expression was measured in 3day of fifth instar larvae of abnormal uric acid synthesis Bombyx mori mutant of op.

Microarray-based Gene Expression Analysis in the Silkworm Bombyx mori After Parasitization by Tachinid Flies

Project description:We identified genes regulated by parasitization of the silkworm Bombyx mori by three tachinid parasitoid species, Exorista japonica, Drino inconspicuoides and Pales pavida, using oligonucleotide microarrays. The numbers of genes and their intensity of expression varied with the species of parasitoid, within silkworm hemocytes and fat body. Bombyx mori hemocyte, silkgland and fat body samples parasitizated by Exorista japonica, Drino inconspicuoides and Pales pavida were prepared. Gene expression was compared in these two groups: control and parasitized.

Identify potential maternal genes of Bombyx mori using Digital Gene Expression Profiling

Project description:Maternal genes present in mature oocytes and play a crucial role in the early development of the silkworm. Although maternal genes have been widely studied in many species, there are limited research in Bombyx mori. High-through experimental technology provides a practical way for genome-wide study. Here we show a transcriptome study on silkworm eggs. Unfertilized eggs from five different stages of early development were used for detecting the change situation of gene expression. The expressed genes showed different patterns over time. Maternal genes were annotated according to homology analysis with Drosophila melanogaster. In our result, more than a half expressed maternal genes were fall into four expression patterns and showed downward trend over time. The function annotation of material genes showed that they were related to transcription factor activity, growth factor activity, nucleic acid binding, RNA binding, ATP binding, ion binding and so on. In additional, twenty-two gene clusters including material genes were identified from 18 scaffolds. Altogether, we plotted a profile for maternal genes of Bombyx mori using digital gene expression profiling method. It will provide a base for mother-specific signature research and improve the understanding of early development of silkworm.
