“…In contrast, Autúnez et al (2009) demonstrated that the mRNA levels of vitellogenin in N. ceranae infected worker bees significantly decreased after 7 days of infection. Vitellogenin is a female-specific glucolipoprotein yolk precursor synthesized in the fat body of abdomen (Byrne et al 1989). It plays an important function in immunity and longevity of worker honey bees (Amdam et al 2004).…”

-Nosema ceranae is a microsporidium parasite infecting honey bees worldwide. All colony members including workers, drones, and queens can become infected. In this study, we inoculated queens of age 1, 6, and 12 days post-adult emergence, with N. ceranae spores of different doses and allowed them to age an additional 12 days. The results indicated that younger queens were indeed more susceptible to N. ceranae inoculation than older queens. Moreover, this is the first report of the effects of N. ceranae inoculation on immune gene expression in queens of different ages. Our results demonstrated that the expression of genes related to the bee immunity apidaecin, eater, and vitellogenin in the gut and the remaining abdomen was different among queens of different ages when inoculated with N. ceranae. All three ages of queens inoculated by N. ceranae showed upregulation of apidaecin in gut tissue 6 days after inoculation, but only in queens aged 1 day post-emergence were the differences significant. However, transcript levels of eater were increased in all three ages of queens when sampled on day 12, and significant differences were obtained in queens inoculated at 6 and 12 days post-emergence. We clearly show that immune responses to N. ceranae changes as queen age and this knowledge may provide clues for understanding the ability of queens to resist infection by this gut parasite.Nosema ceranae / honey bee queen / Apis mellifera / supersedure / immunity

“…Previous studies have demonstrated that metal ions, such as calcium and iron play key roles in various biological progresses during embryonic development (Gündel et al, 2007;Montorzi et al, 1995;Taborsky, 1980), and lipids provide essential energy for developing embryos/larvae (Byrne et al, 1989;Gündel et al, 2007;Wallace and Jared, 1969). Therefore the down-regulation of these proteins may be responsible for the developmental toxicity observed.…”

“…In zebrafish, vtgs are encoded by a multiple genes and constitute the majority of yolk proteins (Gündel et al, 2007). Besides being amino acid sources, these proteins can bind to lipids, sugars, phosphates and metal ions and thus provide essential nutrients for embryonic development (Byrne et al, 1989;Gündel et al, 2007;Wallace and Jared, 1969). In order to maintain a regulated supply of nutrients and energy during embryonic development, the degradation of yolk proteins has to be effectively programmed (Gündel et al, 2007).…”

“…It is mainly expressed in the hepatopancreas, and trace amounts of transcript have been found in the ovary during vitellogenesis in P. trituberculatus (Byrne et al, 1989). Increased vitellogenin mRNA in the mature ovary of P. trituberculatus might be useful for ovary development.…”

“…Vitellogenin (Vg) is the precursor of vitellin, the major yolk protein stored in crustacean oocytes that provides free amino acids, lipids, carbohydrates, carotenoids, and minerals to the developing embryo and larva (Byrne et al, 1989). It is mainly expressed in the hepatopancreas, and trace amounts of transcript have been found in the ovary during vitellogenesis in P. trituberculatus (Byrne et al, 1989).…”

ABSTRACT. The swimming crab, Portunus trituberculatus, is an important marine animal and is widely cultured in China. In the present study, suppression subtractive hybridization was applied to identify the differentially expressed genes in the ovaries of mature and immature P. trituberculatus. One hundred and seventy six expressed sequence tag (ESTs) were identified, of which 100 were down-regulated, and 76 up-regulated. BLAST analysis identified 51 unigenes, of which 27 were down-regulated, and 24 up-regulated. Quantitative real-time reverse transcriptase polymerase chain reaction results indicated that the SSH technique is valuable in screening genes related to ovarian development. Genes identified in this study encoded proteins corresponding to a wide range of functions and included immune response protein, transcription initiation factor, metabolic proteins, chromosome, histone h3, ovarian development-related protein, and vitellogenin. In addition, 64 metabolic pathways were annotated in differentially expressed ESTs by using the Kyoto Encyclopedia of Genes and Genomes pathway. Four annotated pathways (oxidative phosphorylation, carbon metabolism, fatty acid degradation, and protein digestion and absorption) appeared to be involved in ovarian development. In ontology analysis, 5.83% of the cellular process genes in reverse subtraction cDNA library are involved in reproduction, and 5.88% involved in developmental process. In up-regulated genes, myosin II-expressed polehole-like protein; histone h3; ovigerous-hair stripping substance; peritrophin 48; and ovarian development-related protein appeared to be involved in ovarian development. Identification of differentially expressed genes in the mature and immature ovary of the swimming crab provides new insights for further studies on the mechanism underlying ovarian development in this species.
