Established animal models have accelerated our understanding of the mechanisms involved in lifespan determination. However, more experimental animals are required to clarify the complex mechanisms behind the phenomena of aging and lifespan. In this study, we reported the variation of lifespan in nine distinct silkworm strains. Lifespan correlated significantly with BmFoxO gene expression in the...
The Autographa californica nucleopolyhedrovirus (AcMNPV) does not infect the silkworm and molecular studies on silkworm insusceptibility have not been performed. In cultured cells of the silkworm, the expression of viral genes has been reported. The expression of AcMNPV genes and their effect in vivo and in vitro was studied. In this study, the early gene, the ecdysteroid UDP-glucosyltransferas...
The domesticated silkworm, Bombyx mori Linn., a lepidopteran molecular model and an important economic insect that are emerging as an ideal molecular genetic resource for solving a broad range of biological problems. The silkworm, B. mori produces massive amount of silk proteins during the final stage of larval development. These proteins are stored in the middle silk gland and they are dischar...
The BTB domain is a conserved protein-protein interaction motif. In this study, we identified 56 BTB domain-containing protein genes in the silkworm, in addition to 46 in the honey bee, 55 in the red flour beetle, and 53 in the monarch butterfly. Silkworm BTB protein genes were classified into nine subfamilies according to their domain architecture, and most of them could be mapped on the diffe...
The Silkworm Knowledgebase (SilkDB) is a web-based repository for the curation, integration and study of silkworm genetic and genomic data. With the recent accomplishment of a approximately 6X draft genome sequence of the domestic silkworm (Bombyx mori), SilkDB provides an integrated representation of the large-scale, genome-wide sequence assembly, cDNAs, clusters of expressed sequence tags (ES...
To explore efficient of different gene transfer methods and to express human granulocyte-macrophage colony-stimulating factor (hGM-CSF) in silk glands of transgenic silkworm, a novel transgenic vector containing a hGM-CSF controlled by silkworm fibroin heavy chain gene promoter (Pfib-H) with a neomycin resistance gene (neo) driven by BmNPV (B. mori nucleopolyhedrovirus) immediate-early gene ie-...
Host-pathogen interactions are complex processes and it is a central challenge to reveal these interactions. Fungal infection of silkworm, Bombyx mori, may induce a variety of responsive reaction. However, little is known about the molecular mechanism of silkworm immune response against the fungal infection. To obtain an overview of the interaction between silkworm and an entomopathogenic fungu...
Some peptides that are highly conserved between insects and mammals have anti-tumor action. Screening for inhibitors of cell growth from animal fluids may provide useful clues to anti-tumor drugs. Inducers of autophagy also have anti-tumor activity. The current authors recently studied a protein found in silkworm hemolymph, Niemann-Pick disease type C2 (NPC2). This protein, which is highly cons...
The silkworm Bombyx mori is an economically important species. White muscardine caused by Beauveria bassiana is the main fungal disease in sericulture, and understanding the silkworm responses to B. bassiana infection is of particular interest. Herein, we investigated the molecular mechanisms underlying these responses in two silkworm strains Haoyue (HY, sensitive to B. bassiana) and Kang 8 (K8...
oral supplementation with potassium bromide (10, 20 and 40 ?g/ml) to fifth instar larvae of csr2, csr4 and csr2xcsr4 crossbreed races of the silkworm, bombyx mori resulted in a significant increase in the fat body glycogen in all the treated groups and in all the three races of the silkworm, b. mori. the fat body protein content was increased with 20 and 40 ?g/ml treated groups in csr2 and csr4...
