Spermidine Enhances the Silk Production by Mulberry Silkworm
Polyamines are ubiquitous low molecular weight polycationic aliphatic amines involved in diverse cellular processes. Spermidine (Spd), a polyamine, has been proved to be crucial for cell survival in various organisms. Our study reports the effect of Spd on the growth of Bombyx mori. Silkworms showed improved silk gland weight and economic parameters in the fifth instar larval stage when treated...
متن کاملRegulation of ornithine decarboxylase activity by spermidine and the spermidine analogue N1N8-bis(ethyl)spermidine.
Polyamine biosynthesis in intact cells can be exquisitely controlled with exogenous polyamines through the regulation of rate-limiting biosynthetic enzymes, particularly ornithine decarboxylase (ODC). In an attempt to exploit this phenomenon as an antiproliferative strategy, certain polyamine analogues have been identified [Porter, Cavanaugh, Stolowich, Ganis, Kelly & Bergeron (1985) Cancer Res...
متن کاملCardiovascular adverse health effect of occupational exposure to Licorice dust
Introduction: Prolonged use of licorice is known to cause headaches hypertension cardiac arrhythmias edema lethargy shortness of breath sodium retention and loss of potassium in healthy people. However to best of authors' knowledge to date the potential adverse health effects of occupational inhalation exposure to licorice dust have not been examined. This study was therefore under look to ad...

متن کاملEnzymatic assay for spermidine.
The polyamine spermidine (NH,(CH&NH(CH&NH,) is widespread in nature. It is present in mammalian tissues (1, 2), plants (3), bacteria (47), ribosomes (6, 8), and bacteriophages (9-11). There are various methods for its identification, including steam distillation (12)) paper chromatography (13-18)) paper electrophoresis (14, 16, 17, 19), ion exchange chromatography (2, 5), gas chromatography (31...
