Differential gene expression in the evolution of sex pheromone communication in New Zealand’s endemic leafroller moths of the genera Ctenopseustis and Planotortrix

Sex pheromone communication in moths has attracted the attention of evolutionary biologists due to the vast array of pheromone compounds used, addressing questions of how this diversity arose and how male reception has evolved in step with the female signal.

An annual cycle of gene regulation in the red-legged salamander mental gland: From hypertrophy to expression of rapidly evolving pheromones

Cell differentiation is mediated by synchronized waves of coordinated expression for hundreds to thousands of genes, and must be regulated to produce complex tissues and phenotypes. For many animal species, sexual selection has driven the development of elaborate male ornaments, requiring sex-specific differentiation pathways.

Báo cáo Y học: Boar salivary lipocalin Three-dimensional X-ray structure and androstenol/androstenone docking simulations

The X-ray structure of variant A of authentic boar salivary lipocalin (SAL), a pheromone-binding protein specifically expressed in the submaxillary glands of the boar, has been solvedandrefinedat 2.1 A ˚ resolution.The structuredisplays a classical lipocalin fold with a nine-stranded sandwiched bbarrel and anahelix.

Báo cáo khoa học: Pherokine-2 and -3 Two Drosophila molecules related to pheromone/odor-binding proteins induced by viral and bacterial infections

Drosophilais a powerful model system to study the regula-tory and effector mechanisms of innate immunity. To iden-tify molecules induced in the course of viral infection in this insect, we have developed a model based on intrathoracic injection of the picorna-like DrosophilaCvirus(DCV).We have used MALDI-TOF mass spectrometry to compare the hemolymph of DCV infected flies and control flies. By contrast with the strong humoral response triggered by injectionof bacteriaor fungal spores, we have identifiedonly one molecule induced in the hemolymph of virus infected flies....

Báo cáo khoa học: Puriﬁcation and characterization of pheromaxein, the porcine steroid-binding protein A member of the secretoglobin superfamily

Low molecular mass proteins are implicated in chemical communication throughout mammalian species, being involved in both perception and delivery of pheromonal compounds. In boars, pheromones are secreted in saliva to cause oestrous sows to take up the mating stance. These pheromones are the 16-androstene steroids, 5a-androsten-3a-ol and 5a-androsten-3-one. The submaxillary glands of boars contain a low molecular mass protein, pheromaxein, which is capable of binding these 16-androstene phero-mones. ...
