  • 실크는 우수한 광택, 촉감, 물성을 바탕으로 하여 인류에 있어 최고의 의류용 섬유로서 널리 이용되어 왔으며 최근에는 생체적합성 등을 활용한 의료용 및 생물공학용 소재로서 응용하고자 하는 연구가 활발히 진행 중에 있다[1-2]. 그러나 실크의 경우 누에로부터 얻어지는 천연섬유로서 합성섬유와는 달리 누에로부터 토사되면서 그 구조 및 형태가 결정되어 고정되는 단점을 안고 있어 의류용 및 산업용 분야로의 활용에 있어 한계가 있다. (중략)

  • We characterized embryo early gene (EEG)-704 promoter of the silkworm Bombyx mori, which is specifically regulated in the development stages. To determine core promoter region, 10 different partial mutant clones were tested by luciferase assay in Sf9 cells. About 1.5 kb promoter shows higher luciferase activity than constitutive promoter (BmA3). Interestingly, EEG-704 shares the same DNA sequences with BmHsp20.8 by the result of BLAST analysis; its expression is also increased under heat shock condition. Development of such promoter inducible, directly or indirectly in the developmental-stage, is very useful in making recombinant proteins in transgenic silkworms.

  • Current study was to investigate the potential effects of silkworm, Bombyx mori L. fermented with Bacillus subtilis (BFSP) and Aspergillus kawachii (AFSP) at the 5% (w/w) levels in Sprague-Dawley rats, which was intoxicated with 1% (w/w) orotic acid (OA) for 10 days. The rat group administered silkworm powder showed improvements in fatty liver condition. Consumption of fermented silkworm powder reduced triglyceride concentrations in the liver tissues and serum and increased the serum lipid concentrations to normal levels, thereby aiding in improving fatty liver conditions. These effects were more pronounced in the BFSP than that in SP or AFSP in orotic acid-induced hepatotoxicity and oxidative stress. Based on these results, fermented silkworms are considered to be a material with significant potential for development into a functional health food that can improve fatty liver conditions.
