[Role of zinc and other metals in the biological activity of the serum thymic factor (thymulin)]. 1981

M Dardenne, and J M Pleau, and P Lefrancier, and J F Bach

The serum thymic factor (FTS) used in synthetic or natural form, loses its biological activity after passage on a chelating agent, Chelex 100. Such activity is recovered after addition of zinc and, to a lesser degree, of certain other metals. FTS activation is secondary to zinc binding to the peptide. These results indicate the existence of two FTS forms: the first one, deprived of zinc and biologically inactive, the second one containing zinc and biologically active, for which we purpose to coin the name of thymulin.

UI	MeSH Term	Description	Entries
D008670	Metals	Electropositive chemical elements characterized by ductility, malleability, luster, and conductance of heat and electricity. They can replace the hydrogen of an acid and form bases with hydroxyl radicals. (Grant & Hackh's Chemical Dictionary, 5th ed)	Metal
D008810	Mice, Inbred C57BL	One of the first INBRED MOUSE STRAINS to be sequenced. This strain is commonly used as genetic background for transgenic mouse models. Refractory to many tumors, this strain is also preferred model for studying role of genetic variations in development of diseases.

D011485	Protein Binding	The process in which substances, either endogenous or exogenous, bind to proteins, peptides, enzymes, protein precursors, or allied compounds. Specific protein-binding measures are often used as assays in diagnostic assessments.	Plasma Protein Binding Capacity,Binding, Protein
D002614	Chelating Agents	Chemicals that bind to and remove ions from solutions. Many chelating agents function through the formation of COORDINATION COMPLEXES with METALS.

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.	Animal,Metazoa,Animalia
D013935	Thymic Factor, Circulating	A thymus-dependent nonapeptide found in normal blood. Stimulates the formation of E rosettes and is believed to be involved in T-cell differentiation.

D013951	Thymus Hormones	Humoral factors secreted by the thymus gland. They participate in the development of the lymphoid system and the maturation of the cellular immune response.	Thymic Hormones,Hormones, Thymic,Hormones, Thymus
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.
