Genome-wide Identification of Polycomb Target Genes Reveals a Functional Association of Pho with Scm in Bombyx mori

Project description:Polycomb group (PcG) proteins are involved in chromatin modifications for maintaining gene repression that play important roles in the regulation of gene expression, tumorigenesis, chromosome X-inactivation, and genomic imprinting in Drosophila melanogaster, mammals, and even plants. PcG proteins act together in three multimeric complexes, Polycomb repressive complex 1 (PRC1), Polycomb repressive complex 2 (PRC2), and Pleiohomeotic repressive complex (PhoRC), to repress transcription of the target genes. Here, we identified Polycomb target genes in Bombyx mori using genome-wide expression screening based on the knockdown of the BmSCE, BmESC, BmPHO, or BmSCM gene, which represent the distinct complexes. As a result, most genes were up-regulated after knocking down these four PcG genes, which indicated a potential epigenetic mechanism on the regulation of these genes expression by the PcG system. The further analysis of our data will provide some important information for the regulation mediated by PcG proteins in Bombyx mori.

Unique territorial and sub-chromosomal organization revealed in the holocentric moth Bombyx mori [ChIP-seq]

Project description:Genome organization in diverse eukaryotes follows conserved principles including the formation of chromosome territories (CT), chromatin compartments, and TADs. Here, we describe the 3D architecture of holocentric chromosomes in the silkworm Bombyx mori. At the genome-wide scale, B. mori chromosomes are highly territorial lacking any visible trans contact pattern. At the chromosomal scale, B. mori chromosomes segregate into three chromatin compartments: an active A and an inactive B as described in other eukaryotes, and a third type, X, with a unique contact pattern. Compartment X is strongly enriched for short-range interactions and depleted of long-range interactions, hosts a specific combination of genetic and epigenetic features and localizes towards the periphery of CT. Biophysical simulations reveal the necessity of the combined effects of affinity-based compartmentalization and activity-based loop extrusion to lead to the unique interaction patterns observed. Our analyses contribute to our understanding how chromosomes fold highlighting the evolutionary plasticity of 3D genome organization.

Microarray-based gene expression profiles of silkworm brains

Project description:Molecular genetic studies of Bombyx mori have led to profound advances in understanding the regulation of development. Bombyx mori brain, as a main endocrine organ, plays important regulatory roles in various biological processes. The microarray technology will allow the genome-wide analysis of gene expression patterns in silkworm brains. We reported microarray-based gene expression profiles in silkworm brains at four stages including V7, P1, P2 and P3. A total of 4,550 genes were transcribed in at least one selected stage. Of these, clustering algorithms separated the expressed genes into stable expressed genes and variable expressed genes. The results of the gene ontology (GO) and kyoto encyclopedia of genes and genomes (KEGG) analysis of stable expressed genes showed that the ribosomal and oxidative phosphorylation pathways were principal pathways. Secondly, four clusters of genes with significantly different expression patterns were observed in the 1,175 variable expressed genes. Thirdly, thirty-two neuropeptide hormones genes, nine neuropeptide-like precursor genes, and 117 cuticular protein genes were expressed in selected developmental stages. The present study deﬁned major characteristics of the transcriptional profiles in the brains of Bombyx mori at the specific development stages. Our data will provide abundant information that will be useful in future research.
