... to a longer ecdysis cycle and smaller individuals. This phenotype was mirrored in shrimps injected with novel miR-26 agomirs, but the opposite phenotype occurred in shrimps injected with novel miR-26 antagomirs (i.e. the ecdysis cycle was shortened and body length was increased). After injection of 20...

...Y. Zilberstein; J. Ewer; A. Ayali SUMMARY In insects, continuous growth requires the periodic replacement of the exoskeleton during the moult. A moulting insect displays a stereotypical set of behaviours that culminate in the shedding of the old cuticle at ecdysis. Moulting is an intricate process...

... of a neuroendocrine system to stimulate ecdysis, the behaviors used to shed the old cuticle at the culmination of each molt. Here we show that two evolutionarily conserved transcription factor genes, the basic helix-loop-helix (bHLH) gene dimmed ( dimm )and the basic-leucine zipper (bZIP) gene cryptocephal ( crc...

... of the frontal ganglion (FG), a small ganglion of approximately 35 neurons that lies anterior to the brain on the dorsal surface of the foregut ( Fig. 1 ; Miles and Booker, 1994 ). In order to determine whether the foregut plays a role in the resorption of the MF prior to ecdysis, we examined molting larvae...

... that the first ecdysis is important for establishing the barrier to TEWL. We found that skin resistance to TEWL increases twofold following the first postnatal ecdysis, corresponding with a roughly twofold increase in thickness and deposition of lamellar lipids in the mesos layer, the site of the skin...

Surgical experiments involving the transection of the nerve cord or removal of parts of the brain showed that the proctodeal nerve activity...
