Project description:Royal jelly has long been recognized as health food, with a high content of proteins. These proteins play important roles in honeybee caste and human health, but the proteomic analysis of those low-abundance proteins in royal jelly is always a challenge. Herein, we used the Osboren classification method to separate the royal jelly proteins of Xinjiang black bees, a sub-species of Apis mellifera mellifera, into various fractions. The globulin, ethanol-soluble protein and glutelin fractions were further separated by SDS-PAGE, and proteomic analysis was carried out by LC-MS/MS and searching against the NCBI database. A total of 63 proteins with definitive names were identified, in which 41 proteins were identified for the first time in royal jelly. The Osboren classification method combined with one-dimensional gel electrophoresis based proteomic analysis allows the identification of low-abundance proteins, and greatly extends the knowledge about the components and functions of royal jelly proteins.

Project description:Royal Jelly (RJ) is a product made by honey bee workers and is required for queen differentiation and accompanying changes in queen body size, development time, lifespan and reproductive output relative to workers. Previous studies have reported similar changes in Drosophila melanogaster in response to RJ. Here, we quantified viability, development time, body size, productivity, lifespan and genome wide transcript abundance of D. melanogaster reared on standard culture medium supplemented with increasing concentrations of RJ. We found that lower concentrations of RJ do induce significant differences in body size in both sexes; higher concentrations reduce size, increase mortality, shorten lifespan and reduce productivity. Increased concentrations of RJ also consistently lengthened development time in both sexes. RJ is associated with changes in expression of 1,581 probe sets assessed using Affymetrix Drosophila 2.0 microarrays, which were enriched for genes associated with metabolism and amino acid degradation. The transcriptional changes are consistent with alterations in cellular processes to cope with excess nutrients provided by RJ, including biosynthesis and detoxification, which might contribute to accelerated senescence and reduced lifespan.

Project description:MRJP-3 is an RNA binding protein that binds both double- and single-stranded RNA in vitro. To test whether i) MRJP-3 binds RNA in its natural environment, the royal jelly (RJ) and ii) to characterize its RJ RNA partners; a pull down followed by RNA-seq system was developed. MRJP-3 bound RNA was compared to total RJ RNA extracted from the same hive. To establish the system, we first incubated biotinylated MRJP-3, or biotinylated BSA in RJ and pulled the proteins out with strepavidin coated magnetic beads followed by RNA extraction and bioanalyzer profiling. MRJP-3 pull out was enriched for RNA compare to the BSA and just beads controls. The RNA population pulled down with MRJP-3 has similar profile to the total RJ RNA, further demonstrating the MRJP-3 has no affinity to a certain RNA species.

Project description:Vascular smooth muscle cells (VSMCs) are a major cell type of the arterial wall and their functionality is associated with blood pressure regulation. Although royal jelly (RJ) has reported effects on anti-hypertension, the mechanism of blood pressure regulation by major royal jelly protein 1 (MRJP1), the most abundant RJ protein, is still unknown. Therefore, mrjp1 gene was delivered into mouse VSMCs to investigate how MRJP1 influences the VSMC functionality by functional and proteomic analysis.The data here are the proteomic analysis of triplicated control and MRJP1 expressing VSMCs.

Project description:Intervention 1: Intervention group: 32 patients will be selected according to the inclusion criteria, using the available sampling method, who come in different work shifts and on different days of the week. After stating the objectives of the study in a meeting and obtaining consent from the patients, the patients enter the study. Demographic information of all participants will be recorded by the researcher. A training session will be held on how to store and use honey and royal jelly. Before receiving the third course of chemotherapy drug, blood parameters test (CBC) will be done and the answers will be recorded in the checklist. The MFI fatigue questionnaire will also be completed by the researcher before the intervention through an interview. Then, in the intervention group, royal jelly prepared from an accredited local apiary approved by the University of Medical Sciences, using cool boxes containing ice and maintaining the cold chain, will be provided to the patients at the time of the visit and they will be asked to finish Carry out the study of royal jelly and keep it in the refrigerator. 10 grams of natural honey containing one gram of royal jelly (10% concentration) will be consumed orally for five days in the morning on an empty stomach in the intervention group. Again, before receiving the next course of chemotherapy, blood parameters will be tested in the aforementioned laboratory. The questionnaire related to the measurement of fatigue will also be completed by the researcher before the start of the new course of chemotherapy through an interview. The data is then analyzed. Intervention 2: Control group: The number of 32 patients will be selected according to the inclusion criteria, using available sampling method, who come in different work shifts and on
Primary outcome(s): Blood cell count includes the count of white blood cells, red blood cells, hemoglobin and platelets, which will be evaluated according to laboratory results. Timepoint: After the end of the second round of chemotherapy, the intervention is carried out using royal jelly and placebo for five days. After two weeks from the end of the intervention, direct evaluation will be done by the researcher. Method of measurement: Counting blood cells using laboratory results (CBC).
Study Design: Randomization: Randomized, Blinding: Single blinded, Placebo: Used, Assignment: Parallel, Purpose: Supportive, Randomization description: To assign the samples to the study groups randomly, the design of random permutation blocks of two groups with blocks of four will be used, with 32 samples in group A (intervention group) and 32 samples in group B (intervention group) control) will be considered. Then the website https://www.sealedenvelope.com will be used to determine the required random blocks and their sequence. Sealed envelopes will be used for concealment. In this way, based on the sequence of randomly determined blocks, cards with the letters A and B that show the sequence of allocation will be placed inside the envelope. Then, an envelope will be opened for each participant in the study, and based on the card inside the envelope, the participant will be assigned to the control or intervention group, Blinding description: Sealed envelopes will be used for concealment.
