Honeybee egg size project-egg proteomics

ABSTRACT: Using the honey bee (Apis mellifera) as a model, we confirmed that honey bee queens actively adjust egg size in response to the number of workers: Queens lay smaller eggs in colonies with more worker bees than when in colonies with few workers. Reduced colony size also causes decreasing ovary weight but upregulation of energy production and protein processing in the ovaries. Complementary metabolomic and proteomic analyses of the produced eggs indicate that amino acid metabolism, cell development, and cell maturation processes are elevated in bigger eggs. Our study thus provides the first mechanistic insights into the adjustment of egg size in the honey bee, a model for complex social systems that demand integration of individual and collective life-history optimization.

Environmental variation selects for the adaptive plasticity of maternal provisioning. Even though developing honeybees find themselves in a protected colony environment, their reproductively specialized queens actively adjust their maternal investment, even among worker-destined eggs. However, the potentially adaptive consequences of this flexible provisioning strategy and their mechanistic basis are unknown. Under natural conditions, we find that the body size of larvae hatching from small eggs ...[more]

Proteomic portraits of egg quality in zebrafish (Danio rerio)

Project description:Humans and animals have problems producing eggs with high embryo developmental competence, but the causes of poor egg quality are usually unknown. This study delivered the first proteomic portraits of egg quality in zebrafish, a leading model for vertebrate development. Egg batches of good and poor quality, evidenced by embryo survival for 24 h, were used to create pooled or replicated sample sets subjected to different levels of fractionation before LC-MS/MS. Obtained spectra were searched against a custom zebrafish proteome database and detected proteins were annotated, categorized and quantified based on their normalized spectral counts. Manual and automated enrichment analyses were highly confirmative, showing that good and poor quality eggs have disparate proteomes. Proteins involved in protein synthesis, energy metabolism, and lipid metabolism, and certain vitellogenin products were strikingly underrepresented in poor quality eggs. Poor quality eggs also had significantly higher representation of proteins related to immune system and endosome/lysosome functioning, oncogenes, and apoptosis, as well as lectins and egg envelope proteins. Quantitative comparisons of highly abundant proteins revealed 9 candidate egg quality markers warranting further study. In conclusion, the zebrafish egg proteome appears to be linked to embryo developmental potential, a phenomenon that begs further investigation.

Ovulation suppression prevents the increase in egg aneuploidy with maternal age in mammals

Project description:Multiple mechanisms likely contribute to the increase in chromosome missegregation that leads to production of aneuploid eggs and fetuses at advanced maternal age. It is therefore considered unlikely that a single approach could prevent age-related egg aneuploidy. Here we show using three independent approaches that ovulation reduction is sufficient to prevent egg aneuploidy in aged mammals. To gain insights into the mechanism underlying the rescue in egg aneuploidy, we show that ovulation suppression correlates with retention of chromosomal Rec8-cohesin, implying that ovulations are linked to cohesin deterioration. Moreover, we discovered that ageing alters 3D chromatin organization by single-nucleus Hi-C (snHi-C). Extruded loops increase in size with age and this is retarded by ovulation reduction. We conclude that reducing ovulations leads to retention of chromosomal Rec8, which maintains interphase chromatin structure and promotes chromosome segregation and production of euploid eggs. Importantly, our data suggest that ovulation itself contributes to the maternal age effect. This work provides the first experimental evidence that progesterone treatment reduces egg aneuploidy and suggests that hormonal contraception can reduce the risk of trisomic pregnancies like Down’s syndrome at advanced maternal age.

Egg quality after natural and controlled ovulation

Project description:The present study aimed at studying the rainbow trout egg transcriptome using 9152-cDNA microarrays after natural or controlled ovulation. The analysis of egg transcriptome after natural or controlled ovulation led to the identification of 26 genes. We observed that both hormonal induction and photoperiod control of ovulation induced significant changes in the egg mRNA abundance of specific genes. We demonstrate that hormonal induction of ovulation has an impact on the egg mRNA abundance of specific genes even though the resulting effects on the developmental potential of the egg is so far unknown. In addition, we also identified 1 gene exhibiting a differential mRNA abundance in eggs of varying developmental potential. Keywords: Egg quality-dependent

Conserved Arabidopsis response to oviposition and crude egg extract treatment

Project description:Although a seemingly harmless developmental stage of herbivores, insect eggs trigger efficient plant defenses that include necrosis, callus formation, accumulation of ovicidal compounds and release of volatiles to attract egg predators. The large white butterfly Pieris brassicae deposits batches of 20-30 eggs onto Arabidopsis leaves, causing a large transcriptional reprograming that is drastically distinct from the expression profile triggered by larval feeding. Also, P. brassicae eggs induce localized cell death, accumulation of reactive oxygen species (ROS) and salicylic acid (SA), and expression of PTI-related genes, suggesting that egg-associated molecular patterns (EAMPs) activate a response that is similar to the response induced by microbial pathogens. We previously reported that a crude P. brassicae egg extract (EE, soluble fraction from crushed eggs) induced similar responses as oviposition, including ROS and SA accumulation, cell death and defense gene induction. In order to compare oviposition and EE treatment at the transcriptome level, we analyzed changes in transcipt abundance with P. brassicae EE or after natural oviposition. After 5 days, hundreds of genes were significantly upregulated by each treatment and their induction was highly similar between treatments. This conserved transcriptomic signature thus strongly supports our previous observations that oviposition and EE treatment trigger comparable responses in Arabidopsis.

Egg transcriptome reveals molecular signature to predict developmental success and novel maternal-effect genes

Project description:Good quality or developmentally competent eggs result in high survival of progeny. Previous research has shed light on factors that determine egg quality, however, large gaps remain. Initial development of the embryo relies on maternally-inherited molecules, such as transcripts, deposited in the egg, thus, they would likely reflect egg quality. We performed microarray analysis on zebrafish fertilized eggs of different quality from unrelated, wildtype couples to obtain a global portrait of the egg transcriptome to determine its association with developmental competence and to identify new candidate maternal-effect genes. Fifteen of the most differentially expressed genes (DEGs) were validated by quantitative real-time PCR. Gene ontology analysis showed that enriched terms included ribosomes and translation. In addition, statistical modeling using partial least squares regression and genetics algorithm also demonstrated that gene signatures from the transcriptomic data can be used to predict reproductive success. Among the validated DEGs, otulina and slc29a1a were found to be increased in good quality eggs and to be predominantly localized in the ovaries. CRISPR/Cas9 knockout mutants of each gene revealed remarkable subfertility whereby the majority of their embryos were unfertilizable.Our novel findings suggested that even in varying quality of eggs due to heterogeneous causes from unrelated wildtype couples, gene signatures exist in the egg transcriptome, which can be used to predict developmental competence. Further, transcriptomic profiling revealed two new potential maternal-effect genes that have essential roles in vertebrate reproduction.

Transcriptomic profiling of egg quality in seabass (Dicentrarchus labrax)

Project description:The aim of the project was to identify differently expressed genes in eggs of European seabass (Dicentrarchus labrax) characterized by different quality. In this way it was expected to identify genes possibly being a molecular indicator of egg quality in this species, which was never studied to date. For the study microarray analysis of over 26 thousand genes in 16 egg batches was performed. Additionally, for each egg batch biological quality was determined, what allowed to compare the gene expression profile with overall egg quality (divided into two groups representing ‘high’ and ‘low’ egg quality). The analysis allowed to identify 39 differently expressed genes between the two groups representing ‘high’ and ‘low’ egg quality. From those genes, expression level of 7 were verified by real-time qPCR which confirmed significant difference in expression in 5 of them.
