Honeybee brain - Brain Membrane Proteome and Phosphoproteome Reveal Molecular Basis Associating with Nursing and Foraging Behaviors of Honeybee Workers

ABSTRACT: he brain is a vital organ in regulating complex social behaviors of honeybees including learning and memory. Knowledge of how brain membrane proteins and their phosphorylation underlie the age-related behavioral polyethism is still lacking. We presented the first comprehensive profiling and comparison of brain membrane proteome and phosphoproteome across different ages of adult worker bees in two strains of honeybee (Apis mellifera ligustica): Italian bee (ITB) and royal jelly bee (RJB), a line selected for increased RJ outputs over 4 decades.

The brain is a vital organ in regulating complex social behaviors of honeybees including learning and memory. Knowledge of how brain membrane proteins and their phosphorylation underlie the age-related behavioral polyethism is still lacking. A hitherto age-resolved brain membrane proteome and phosphoproteome were reported in adult worker bees from two strains of honeybee (Apis mellifera ligustica): Italian bee (ITB) and Royal Jelly bee (RJB), a line selected from ITB for increased RJ outputs ove ...[more]

Project description:Honeybee brain has distHoneybee brain has distinct anatomical and functional regions, knowledge on molecular underpinnings of sub-organ to achieve the distinct neural function and the difference between the eastern and western honeybees are still missing. Here, the proteomes of three sub-organs of eastern and western honeybee brains were compared. Mushroom bodies (MBs) and optical lobes (OLs) may by employed similar proteome architectures to drive their domain-specific neural activity in both bee species. In MBs, protein metabolism and Ca2+ transmembrane transport are the key role players in driving the learning and memory by modulating the synaptic structure and signal transduction to consolidate memory trace. In OLs, ribonucleoside metabolism and energy production play major roles to underpin visual system by maintaining G-protein cycle and membrane electrical charge potential. However, in antennal lobes (ALs), it has evolved distinct proteome settings to prime the olfactory learning and memory in two bee species. In ALs of Apis cerana cerana (Acc), actin cytoskeleton organization is key for plasticity of glomeruli and intracellular transport to sustain the olfactory signaling. Whereas, in ALs of Apis mellifera ligustica (Aml), hydrogen and hydrogen ion transport are vital to support olfactory process by supplying energy and maintaining molecule transport. Noticeably, in ALs of Acc, the exclusively enriched functional groups acting as second messenger and neurontransmitter of signal transduction, and the enhanced protein metabolism to regulate the plasticity of synaptic structure for formation of memory, suggest that Acc may have evolved a better sense of smell than that of Aml. Our first proteome data is helpful as starting point for further analysis of neural activity in brain sub-area of honeybee and other insects.inct anatomical and functional regions, knowledge on molecular underpinnings of sub-organ to achieve the distinct neural function and the difference between the eastern and western honeybees are still missing.

Project description:The honeybee brain is comprised of a nervous system that sufficiently regulates this life transition. Knowledge about how protein phosphorylation functions in regards to the neurobiological activities in the honeybee brain to drive the age-specific labor division is still lacking. Protein phosphorylation, the most common post-translational modification (PTM), is a key switch for rapid on-off control of signaling cascades that regulate cell differentiation and development, enzyme activity and metabolic maintenance in living cells. A fundamental mechanism for regulating signaling network and protein activity is the covalent PTM of serine (Ser), threonine (Thr), and tyrosine (Tyr) residues with phosphate. Fortunately, because of advances in phosphopeptide enrichment and improvements in mass spectrometry (MS) instrumentation and methods, phosphoproteomics has enabled large-scale identification of protein phosphorylation sites and phosphorylation networks in biological samples. Although the proteome has been mapped in the brain of nurse and forager bees, knowledge about age-specific effects of phosphorylation regulation on proteins in the honeybee brain is still lacking. Moreover, information in regards to the honeybee phosphoproteome is also very limited. Only very recently, in-depth phosphoproteomics analyses of protein phosphorylation networks in the hypopharyngealgland of the honeybee have been reported. Although the phosphoproteome analyses during the development of brood and salivary glands has been reported, only very limited proteins were phosphorylated and phosphorylation sites of those phosphoproteins were not assigned. Therefore, a comprehensive characterization of phosphoproteomics and changes in the brains of nurse and forager bees is key to understand the phosphorylation events underlying age-specific physiology to achieve the completion of biological missions in this well-organized social community of the honeybee. Honeybee (A. m. ligustica) colonies used for sampling were raised at the apiary of the Institute of Apicultural Research, Chinese Academy of Agricultural Science, Beijing. Newly emerged (<12 h after emergence) worker bees were marked on their thoraxes and placed back into the colonies to develop and then the marked nurse and forager bees were collected on days 10 and 20, respectively. There were 150 bees sampled from each of the five colonies which have queens at the same age. In brief, for each time point, worker bees were sampled from five colonies, and pooled all samples for further analysis. This procedure was repeated three times, so that we finally ended up with three independent biological replicates per time point, each consisting of 150 honeybees. Then their brains were dissected, and the brain samples were pooled and stored at −80 °C for further analysis. All the colonies were managed with almost identical population, food, and brood during the nectar flow of chaste berry (Vitexnegundo L.) in June.
