Insulin-like hypoglycemic and immunological activities in honeybee royal jelly.
An aqueous extract of royal jelly from Apis mellifera produced hypoglycemia when injected into larvae of Manduca sexta. Application of specific radioimmunoassay to the partially-purified extract showed that royal jelly contains several insulin-like peptides, the major immunoreactive component of which has an apparent mol. wt similar to that of bovine insulin. These results suggest the existence...
متن کاملThe origin of the nucleic Acid bases found in the royal jelly of the honeybee.
The discovery that the royal jelly of the honeybee contains large quantities of nucleic acids raises the question, "Where do these nucleic acids come from?" A review of pertinent literature strongly suggests that the same mechanism is involved as in the case of the extrachromosomal DNA of amphibian oocytes.
متن کاملThe immunostimulatory effect of the recombinant apalbumin 1-major honeybee royal jelly protein-on TNFalpha release.
Apalbumin1 (Apa1) is the major royal jelly (RJ) and honey glycoprotein having various biological properties. We have previously demonstrated that Apa1 is a regular component of honey and honeybee pollen and stimulates macrophages to release tumor necrosis factor alpha (TNFalpha). The recombinant Apa1 (rApa1) and its four recombinant protein fragments derived on the basis of partial tryptic prod...
متن کاملIdentification of a Novel Hypocholesterolemic Protein, Major Royal Jelly Protein 1, Derived from Royal Jelly
Royal jelly (RJ) intake lowers serum cholesterol levels in animals and humans, but the active component in RJ that lowers serum cholesterol level and its molecular mechanism are unclear. In this study, we set out to identify the bile acid-binding protein contained in RJ, because dietary bile acid-binding proteins including soybean protein and its peptide are effective in ameliorating hyperchole...
