Multiple phosphorylation of ribosomal protein S6 and specific protein synthesis are required for prothoracicotropic hormone-stimulated ecdysteroid biosynthesis in the prothoracic glands of Manduca sexta.

TL;DR: This review concerns three aspects of ecdysteroidogenesis: how the brain neuropeptide prothoracicotropic hormone initiates a transductory cascade in cells of the protharacic gland, which results in an increased rate of ecdysone biosynthesis and a series of reactions only now being understood because of the use of a combination of classical biochemistry and molecular genetics.

TL;DR: It is shown that vitellogenin is a source for the proteinaceous royal jelly that is produced by the hive bees, which suggests that the evolution of a brood-rearing worker class and a specialized forager class in an advanced eusocial insect society has been directed by an alternative utilization of yolk protein.

TL;DR: It is demonstrated that, in Drosophila, nutrition modifies the timing of development by acting on the prothoracic gland, which secretes the molting hormone ecdysone, which extends the duration of growth and increases animal size.

TL;DR: The cysteines involved in intra- and intermonomer cross-linking of bombyx prothoracicotropic hormone (PTTH) are conserved in the Antheraea and Samia sequences, suggesting very similar folding patterns.

TL;DR: This assay is very reproducible and rapid with the dye binding process virtually complete in approximately 2 min with good color stability for 1 hr with little or no interference from cations such as sodium or potassium nor from carbohydrates such as sucrose.

TL;DR: Using an improved method of gel electrophoresis, many hitherto unknown proteins have been found in bacteriophage T4 and some of these have been identified with specific gene products as mentioned in this paper.

TL;DR: The selective blockade of the p70 S6 kinase activation cascade by the rapamycin–FKBP complex implicates this signalling pathway in the regulation of T cell entry into S phase.

TL;DR: The pathways for mitogen-stimulated S6 phosphorylation are discussed and members of each family have been cloned.
