Proteomic Analysis of the Royal Jelly and Characterization of the Functions of Its Derivation Glands in the Honeybee
To identify candidate royal jelly (RJ) proteins that might affect the physiologic status of honeybee colony members, we used shotgun …

Identification of Kakusei, a Nuclear Non-Coding RNA, as an Immediate Early Gene from the Honeybee, and Its Application for Neuroethological Study
The honeybee is a social insect that exhibits various social behaviors. To elucidate the neural basis of honeybee behavior, we detected …

Tolerance of Anhydrobiotic Eggs of the Tardigrade Ramazzottius Varieornatus to Extreme Environments
Tardigrades are tiny (less than 1mm in length) invertebrate animals that have the potential to survive travel to other planets because …

Detection of Neural Activity in the Brains of Japanese Honeybee Workers during the Formation of a Hot Defensive Bee Ball
Anti-predator behaviors are essential to survival for most animals. The neural bases of such behaviors, however, remain largely …

Two Novel Heat-Soluble Protein Families Abundantly Expressed in an Anhydrobiotic Tardigrade
Tardigrades are able to tolerate almost complete dehydration by reversibly switching to an ametabolic state. This ability is called …

Loss of Genes for DNA Recombination and Repair in the Reductive Genome Evolution of Thioautotrophic Symbionts of Calyptogena Clams
BACKGROUND: Two Calyptogena clam intracellular obligate symbionts, Ca. Vesicomyosocius okutanii (Vok; C. okutanii symbiont) and Ca. …

Suppression of the Immune Response Potentiates Tadpole Tail Regeneration during the Refractory Period
Regenerative ability varies depending on animal species and developmental stage, but the factors that determine this variability remain …

Inducible- and Constitutive-Type Transcript Variants of Kakusei , a Novel Non-Coding Immediate Early Gene, in the Honeybee Brain
We previously identified a novel non-coding immediate early gene, termed kakusei , from the honeybee (Apis mellifera) and used it as a …
