cuticle

  1. in both animals and plants, a thin noncellular layer secreted by the epidermis. In higher plants it covers all the exterior, except where stomata and lenticels occur, and prevents water loss (cuticularization). In many arthropods, it forms part of the EXOSKELETON and is composed of CHITIN and PROTEIN, with a calcareous element in CRUSTACEANS.
  2. the epidermal cells of vertebrates (the stratum corneum) that have been converted to KERATIN (as in hair, feathers, scales, nails, claws, hooves, horns, etc.), giving proofing against water loss, bacterial entry and ultraviolet light.

Hypotheses have been proposed, including that BPUs interfere with the formation of the cuticle due to an increase in chitinase activity (Ishaaya & Casida 1974, Merzendorfer & Zimoch 2003) or that of the chitin by activation of the proteolytic activity of chitin synthase (Leighton et al.
