..., novel miR-26, which inhibits translation of the phosphofructokinase (PFK) gene by targeting the 3′ untranslated region (UTR) of pfk directly, thereby inhibiting molting and body length growth of the freshwater shrimp Neocaridina heteropoda . Lowering expression of pfk by RNA interference (RNAi) led...

... exposed at Drym contained no detectable copper or zinc. Granule formation appeared to be independent of exposure. Within the posterior caeca, granules have been associated with calcium storage during the crustacean molt, rather than in detoxification of trace metals. However, the granular copper burden...

...Kyle S. MacLea; Ali M. Abuhagr; Natalie L. Pitts; Joseph A. Covi; Brandon D. Bader; Ernest S. Chang; Donald L. Mykles SUMMARY Molt-induced claw muscle atrophy in decapod crustaceans facilitates exuviation and is coordinated by ecdysteroid hormones. There is a 4-fold reduction in mass accompanied...

...Jamie Baldwin; Sönke Johnsen SUMMARY In crustaceans with compound eyes, the corneal lens of each facet is part of the exoskeleton and thus shed during molting. Here we used an optomotor assay to evaluate the impact of molting on visual acuity (as measured by the minimum resolvable angle, α min...

... muscles when molting was induced by either eyestalk ablation (ESA) or multiple limb autotomy (MLA). However, the effect of molt induction was greater in the claw muscle. By late premolt, Gl-Mstn mRNA in the claw muscle decreased 81% and 94% in ESA and MLA animals, respectively, and was negatively...

...Jennifer R. A. Taylor; Jack Hebrank; William M. Kier SUMMARY Molting in crustaceans involves significant changes in the structure and function of the exoskeleton as the old cuticle is shed and a new one is secreted. The flimsy new cuticle takes several days to harden and during this time crabs rely...

...Sung Gu Lee; Brandon D. Bader; Ernest S. Chang; Donald L. Mykles SUMMARY Two eyestalk (ES) neuropeptides, molt-inhibiting hormone (MIH) and crustacean hyperglycemic hormone (CHH), increase intracellular cGMP levels in target tissues. Both MIH and CHH inhibit ecdysteroid secretion by the molting...

...Jennifer E. Bestman; Ronald Booker SUMMARY In the moth, Manduca sexta , anterior foregut motility is modulated during the larval–larval molts in order to control the timing of molting fluid (MF) ingestion. MF is the enzymatic mixture that destroys the outer cuticle so that it can be shed at the end...

...H.-W. Kim; E. S. Chang; D. L. Mykles SUMMARY Crustacean muscle has four calpain-like proteinase activities (CDP I, IIa,IIb and III) that are involved in molt-induced claw muscle atrophy, as they degrade myofibrillar proteins in vitro and in situ . Using PCR cloning techniques, three full-length...

...Jennifer E. Bestman; Ronald Booker SUMMARY We examined the role of the foregut in the resorption of molting fluid (MF)from the exuvial space during the last larval–larval molt of the moth Manduca sexta . In intermolt larvae, the activity of the foregut is characterized by robust peristaltic...
