Project description:Using mRNA next generation sequencing, we analyze the transcriptome of Musca domestica embryos through five stages of early development: from syncytial blastoderm to dorsal closure stage.

Project description:Illumina HiSeq 2000 RNASeq was conducted on the mRNA fraction of three adult female Musca domestica strains. Two strains were the insecticide susceptible strains CS and aabys, which has five distinct recessive morphological markers, one on each of the five autosomes in M. domestica. The third strain was ALHF, which is a highly insecticide resistant strain obtained in Alabama. The reference transcriptome was generated de novo using Trinity. The coding trimmed sequences from Augustus were then used as the mapping reference for the individual FASTQ files from each strain. trace reads were mapped using RSEM to generate FPKM estimates. Gene expression levels were compared to the ALHF strain using EdgeR to identify genes that were downregulated in both aabys and CS.

Project description:To investigate how MdCht9 contribute to the development and digestion of Musca domestica, we silenced the chitinase gene 9 (MdCht9) by its dsRNA, while silenced the GFP as the control. Then we compared the differental expression genes between the test group and the control group.

Project description:Housefly (Musca domestica L.) associated microbiota changes continuously throughout the host life cycle
| PRJEB31063 | ENA
Project description:Using mRNA next generation sequencing, we analyze the transcriptome of Musca domestica embryos through five stages of early development: from syncytial blastoderm to dorsal closure stage. We select 100 embryos for five developmental stages: syncytial blastoderm, cellular blastoderm, gastrula, germ band extension and dorsal closure. A total of 10 samples of mRNA were obtained, represent two biological replicates for each stage.

Project description:Background: While the luminal microbiome composition in the human cervicovaginal tract has been defined, the presence and impact of tissue-adherent ectocervical microbiota remain incompletely understood. Studies of luminal and tissue-associated bacteria in the gastrointestinal tract suggest that they may have distinct roles in health and disease. Here, we performed a multi-omics characterization of paired luminal and tissue samples collected from a clinically well-characterized cohort of Kenyan women. Results: We identified a tissue-adherent bacterial microbiome, with a higher alpha diversity than the luminal microbiome, in which dominant genera overall included Gardnerella and Lactobacillus, followed by Prevotella, Atopobium, and Sneathia. About half of the L. iners dominated luminal samples had a corresponding Gardnerella dominated tissue microbiome. Broadly, the tissue-adherent microbiome was associated with fewer differentially expressed host genes than the luminal microbiome. Gene set enrichment analysis revealed that L. crispatus-dominated tissue-adherent communities were associated with protein translation and antimicrobial activity, whereas a highly diverse microbiome was associated with epithelial remodeling and pro-inflammatory pathways. Communities dominated by L. iners and Gardnerella were associated with low host transcriptional activity. Tissue-adherent microbiomes dominated by Lactobacillus and Gardnerella correlated with host protein profiles associated with epithelial barrier stability, and with a more pro-inflammatory profile for the Gardnerella-dominated microbiome group. Tissue samples with a highly diverse composition had a protein profile representing cell proliferation and pro-inflammatory activity. Conclusion: We identified ectocervical tissue-adherent bacterial communities in all study participants. These communities were distinct from cervicovaginal luminal microbiota in a significant proportion of individuals. This difference could possibly explain that L. iners dominant luminal communities have a high probability of transitioning to high diverse bacterial communities including high abundance of Gardnerella. By performing integrative multi-omics analyses we further revealed that bacterial communities at both sites correlated with distinct host gene expression and protein levels. The tissue-adherent bacterial community is similar to vaginal biofilms that significantly impact women’s reproductive and sexual health.
