Royal Jelly Author. Testicular function was assessed in adult male rats treated with royal jelly (RJ) (1 mg/g body wt /day) and/or nicotine at a concentration of 0.005% that simulated the intake of nicotine by heavy smokers. Nicotine significantly lowered serum acid phosphatase and testosterone values and caused chronic inflammation of the testicular interstitium. On an RJ diet, normal reproductive functions were detected, although 50% of tests showed some tubules lined were sertoli cells only. RJ plus nicotine induced a severe decline in testosterone levels and acid phosphatase activity (55% and 26% of control respectively). Testes showed interstitial inflammation and some tubules lined with sertoli cells only (50%). Further investigations are needed to clarify the effects of different doses of RJ on testicular function.

Albert, S; Klaudiny, J (2007) MRJP9, an ancient protein of the honeybee MRJP family with non-nutritional function. Journal of Apicultural Research Vol. 46 (2) 99-104. DOI: 10.3896/IBRA.1.46.2.06 Major royal jelly proteins (MRJPs) form a subfamily within a larger Yellow/MRJP family of proteins. Whereas multiple Yellow-like proteins have been found in all insect genomes including honeybee, MRJPs seem to be restricted to honeybees. Eight MRJP proteins, termed MRJP1-8, have been characterized so far. We found that proteomic analyses of bee hypopharyngeal glands and venom sac identified proteolytic fragments of a protein, which might be a novel member of the MRJP family. Using this information and availability of honeybee genome, we cloned the corresponding cDNA and confirmed by sequencing that it encodes an uncharacterized MRJP9 protein. Interestingly, a cDNA coding for a relative of MRJP9 was found in paper wasp EST library. By phylogenetic analyses we show that MRJP9 is an ancient member of the MRJP family, which diverged prior to occurrence of nutritionally valuable nitrogen-rich repeat regions in MRJPs. Identification of MRJP9 in several bee organs, its comparatively low expression levels there, together with the existence of a MRJP-like protein in wasp indicate that it performs function(s) different from larval nutrition. A novel hypothesis on possible role of MRJP9 found in bee venom as a possible immunosensitizing factor contributing to allergy against royal jelly is discussed.

Albert, S. and Schmitz, J. (2002) Characterization of major royal jelly protein-like DNA sequences in Apis dorsata. Journal of Apicultural Research, 41(3-4), 75-82. The genome of A. dorsata was screened for the 2 major royal jelly protein coding sequences MRJP3 and MRJP5. With PCR primers originally designed for A. mellifera the presumably orthologous sequences in A. dorsata were amplified. Sequence analysis revealed high similarity between the 2 species. As already described for A. mellifera, an orthologous extensive repetitive region was found in the MRJP3 sequence of A. dorsata. The number of reiterated repetitive motifs is highly variable in different individuals, and is therefore well suited as a marker in population studies. The MRJP5 sequence region contains another repetitive region at the orthologous position described for A. mellifera. These findings indicate that the origin of the MRJP protein family can be dated back probably 22 million years to a common ancestor of the 2 Apis species. Accession date: 18 September 2003.

Al-Mufarrej, S. I. and El-Sarag, M. S. A. (1997) Effects of royal jelly on the humoral antibody response and blood chemistry of chickens. Journal of Applied Animal Research, 12(1), 41-47. 40 chickens were divided into 4 equal groups A, B, C and D, each consisting of 5 male and 5 female birds. At 8 weeks of age, the birds of groups B and C were treated each with 200 mg royal jelly (RJ), given orally or subcutaneously, respectively. Simultaneously, both groups, as well as group A were immunized with 0.2 ml of 10% sheep red blood cells (SRBC) suspension in PBS and re- immunized 10 days later with a second similar dose. Group D served as non-immunized control. Treatment with RJ increased antibody production against SRBC in groups B and C, as compared to group A. Blood cholesterol and potassium concentrations were reduced in RJ treated birds, while non-significant changes in concentrations of electrolytes and other blood constituents were recorded. It is concluded that RJ is an effective immunostimulant and that antibody production is more pronounced following subcutaneous administration compared with oral administration, and during secondary immunization compared with primary immunization.

Journal of Agricultural and Food Chemistry, 50(8), 2227-2230. Solid/liquid extraction for gravimetric determination showed similar reproduciblity and repeatability to those of the usual liquid/liquid extraction. For the most accurate results, sample size was 2.5 g royal jelly, and boiling and rinsing times were 20 and 40 min, respectively. Accession date: 9 June 2003. Call number: 638.178. Library code: Bc.

Aziza and Ibrahim, A. E. (2002) Genotoxic effect of diethylaminoethanol in mouse bone-marrow and germ cells. Bulletin of the National Research Centre (Cairo), 27(1), 73-84. When mouse somatic and germ cells were exposed to diethylaminoethanol, the percentage of chromosome abberations increased with increasing dosage. Therapy with royal jelly decreased the percentage of chromosome abberations and repeated therapy for 3 consecutive days decreased the percentage further. Accession date: 9 June 2003.

(2002) Apisimin, a new serine - valine-rich peptide from honeybee (Apis mellifera L.) royal jelly: purification and molecular characterization. FEBS Letters, 528(1/3), 125-129. doi:10.1016/S0014-5793(02)03272-6 A peptide named apisimin was found in royal jelly; N-terminal sequencing showed that this peptide corresponded to the sequence of a cDNA clone isolated from an expression cDNA library prepared from heads of nurse honey bees. No homology was found between the protein sequence of apisimin with a molecular mass of 5540.4 Da and sequences deposited in the Swiss-Prot database. The 54 amino acids of apisimin do not include Cys, Met, Pro, Arg, His, Tyr, and Trp residues. The peptide shows a well-defined secondary structure as observed by CD spectroscopy, and has the tendency to form oligomers. Isoelectrofocusing showed apisimin to be an acidic peptide.

Bilikova, K., Wu, G. and Simuth, J. (2001) Isolation of a peptide fraction form honeybee royal jelly as a potential antifoulbrood factor. Apidologie, 32(3), 275-283. A peptide fraction was isolated using dual dialysis under acidic conditions, and the N-terminal amino acid sequence of its major peptide was elucidated. The sequence corresponds to honey bee royalisin (mol wt 5523 Da) which has been shown to have antibacterial activity against some Gram-positive bacteria [AA 653/92]. Tests showed that the peptide fraction has an inhibitory effect on Paenibacillus larvae subsp. larvae, and on other Gram-positive bacteria, e.g. Bacillus subtilis and Sarcina lutea, and an antifungal effect on Botrytis cinerea. This is the first published evidence of an antibiotic effect of royalsin against a honey bee pathogen. Accession date: 25 April 2002. Call number: 638.121. Library code: Bj. Language: En, de, fr.

Bonomi, A. (2001) Royal jelly in the feeding of weaning pigs. Rivista di Suinicoltura, 42(4), 183-188. Original title: La gelatina reale nell'alimentazione dei suini in fase di svezzamento. The results of research on the use of freeze-dried royal jelly in weaning pig feeding are discussed. Royal jelly, added to mixed feeds at doses of 10, 20 and 30 ppm during a 42-day trial, improved weight gain (10.50%, 17.00% and 23.00%), the feed utilization (4.50%, 7.00% and 10.00%) and health of the pigs; mortality was reduced. The use of freeze-dried royal jelly at 30 ppm is recommended. Accession date: 10 December 2001. Call number: 638.178. Library code: wf. Language: It, en.
