In Paracentrotus lividus embryos, treatment with zinc ions induces the synthesis of the two major stress proteins with the same molecular weight as those induced by heat shock. The developmental stages responsive to zinc ion treatment are the same as those responsive to heat shock. However, zinc treatment induces a longer lasting synthesis of the stress proteins, and, unlike heat shock, does not induce thermotolerance and does not inhibit synthesis of the bulk proteins.

D000818 Animals Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

D015032 Zinc A metallic element of atomic number 30 and atomic weight 65.38. It is a necessary trace element in the diet, forming an essential part of many enzymes, and playing an important role in protein synthesis and in cell division. Zinc deficiency is associated with ANEMIA, short stature, HYPOGONADISM, impaired WOUND HEALING, and geophagia. It is known by the symbol Zn.
