  • Gap junctions are membrane channels that directly connect the cytoplasm of neighboring cells, allowing the exchange of ions and small molecules. Two analogous families of proteins, the connexins and innexins are the channel-forming molecular vertebrates and invertebrates, respectively. Here, we present the molecular cloning and sequences analysis of novel innexiins, Binx2, expressed during Bombyx mori embryonic development. (omitted)

  • Apolipophorin III (apoLp-III) is a protypical exchangeable apolipoprotein that is abundant in hemolymph of many insect species. Its function lies in the stabilization of low-density lipophorin particles (LDLp) crossing the hemocoel in phases of high energy consumption to deliver lipids from the fat body to the flight muscle cells. But, recent studies with naive Galleria mellonella-apoLp-III gave first indications of an unexpected role of that protein in insect immune activation (Niere et al., 1999). (omitted)

  • All of the commercial silkworm races spread to farmhouses are hybrid of first generation, therefore distinction of sex of parent races is essential. But the existing sexual method which distinguish sex by outer sexual characteristics have many problems such as need of skilled worker and excessive efforts for distinction of sex. So more simple and accurate method fur distinction of sex is needed. (omitted)

  • Overproduction of transforming growth factor (TGF)-$\beta$l has been implicated in the pathogenesis of fibrotic diseases. TGF-$\beta$l plays a crucial role in the accumulation of extracellular matrix (ECM) in human and experimental glomerular diseases. However, it remains unclear whether inhibition of TGF- $\beta$l overproduction would suppress TGF- $\beta$l induced ECM accumulation. To inhibit the overproduction of TGF- $\beta$l in experimental glomerulonephritis induced by anti-Thy 1.1 antibody, we introduced antisense oligodeoxynucleotides (ODN) fur TGF- $\beta$l into the nephritic kidney by the HVJ-liposome-mediated gene transfer method.

  • Trichoptera, or caddisflies, comprise one of the major aquatic insect orders. Like Lepidoptera, caddisflies are capable of spinning silk from specially modified salivary glands, and the diversity of ways this silk is used probably accounts for the success of the order as a whole. These utilize silk to construct both larval and pupal shelters, often incorporating materials from the environmental among the silk thread. In this study, we try to find and characterize novel type genes that should be translated to major component protein of aquatic silk. (omitted)

  • Suil (suppressors of initiator codon mutations) is a component of the translation initiation complex which plays an important role in ribosomal recognition of the initiator codon. Here we report the complete cDHA sequence of Bmobyx mori analogy of the Anopheles gambiae suil translation initiation factor gene and expressions of each organ. (omitted)
