Use of alkylated proteins in the monitoring of exposure to alkylating agents. 1984

P B Farmer, and E Bailey, and J B Campbell

Measurement of reaction products of alkylating agents with proteins has been used as a monitor of in-vivo exposure to over 30 such compounds. Doses in animals exposed to directly-acting alkylating agents (e.g., methyl methanesulfonate, ethylene oxide) are directly related to the production of alkylated amino acids in haemoglobin. The erythrocyte dose of alkylating agent, calculated from the extent of haemoglobin alkylation, is in some cases related to liver and extra-hepatic DNA doses; thus, detection of alkylation of haemoglobin may be taken as an indication of a reaction at the carcinogenic target site.

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
D011506 Proteins Linear POLYPEPTIDES that are synthesized on RIBOSOMES and may be further modified, crosslinked, cleaved, or assembled into complex proteins with several subunits. The specific sequence of AMINO ACIDS determines the shape the polypeptide will take, during PROTEIN FOLDING, and the function of the protein. Gene Products, Protein,Gene Proteins,Protein,Protein Gene Products,Proteins, Gene

Dose Response Relationship, Drug,Dose-Response Relationships, Drug,Drug Dose-Response Relationship,Drug Dose-Response Relationships,Relationship, Drug Dose-Response,Relationships, Drug Dose-Response
D004784 Environmental Monitoring The monitoring of the level of toxins, chemical pollutants, microbial contaminants, or other harmful substances in the environment (soil, air, and water), workplace, or in the bodies of people and animals present in that environment. Monitoring, Environmental,Environmental Surveillance,Surveillance, Environmental
D006454 Hemoglobins The oxygen-carrying proteins of ERYTHROCYTES. They are found in all vertebrates and some invertebrates. The number of globin subunits in the hemoglobin quaternary structure differs between species. Structures range from monomeric to a variety of multimeric arrangements. Eryhem,Ferrous Hemoglobin,Hemoglobin,Hemoglobin, Ferrous
D006801 Humans Members of the species Homo sapiens. Homo sapiens,Man (Taxonomy),Human,Man, Modern,Modern Man
D000418 Albumins Water-soluble proteins found in egg whites, blood, lymph, and other tissues and fluids. They coagulate upon heating. Albumin
D000477 Alkylating Agents Highly reactive chemicals that introduce alkyl radicals into biologically active molecules and thereby prevent their proper functioning. Many are used as antineoplastic agents, but most are very toxic, with carcinogenic, mutagenic, teratogenic, and immunosuppressant actions. They have also been used as components in poison gases. Alkylating Agent,Alkylator,Alkylators,Agent, Alkylating,Agents, Alkylating
D000478 Alkylation The covalent bonding of an alkyl group to an organic compound. It can occur by a simple addition reaction or by substitution of another functional group. Alkylations
