Abstract:
:The brain neuropeptide prothoracicotropic hormone (PTTH) stimulates a rapid increase in ecdysteroid hormone synthesis that is accompanied by general and specific increases in protein synthesis, including that of a 70 kDa cognate heat shock protein (hsc 70). To further understand the possible roles of hsc 70, hsc 70 cDNA clones were isolated from a tobacco hornworm (Manduca sexta) prothoracic gland cDNA library. All sequenced clones were highly homologous to the Drosophila hsc 70-4 isoform. Manduca hsc 70 mRNA levels during the last larval instar exhibited a peak at the onset of wandering and a peak that coincided with the major pre-metamorphic peak of ecdysteroid synthesis. Manipulations of the glands' hormonal milieu showed that hsc 70 mRNA levels respond to 20-hydroxyecdysone, dibutyryl cAMP, PTTH and the JH analogue hydroprene. The protein and mRNA data suggest that hsc 70 could be involved in a negative feedback loop regulating assembly of the ecdysone receptor complex.
