[Lead and cadmium toxicity in established mammalian cell lines]. 1978

Y Skreb, and V Habazin-Novak, and N Hors

Lead and cadmium toxicity was evaluated in three mammalian cell lines (tumour : HeLa, transformed : XC and normal : NRK) by means of the modifications of the 3H-TdR incorporation rate in the nucleus of the treated cells. The three cell lines showed different degrees of sensitivity. Sensitivity depended on the line, metal, its concentration and duration of incubation. Cadmium was found to be at least five times more toxic than lead except at low concentration. The normal cell line was more sensitive to cadmium and less sensitive to lead than other lines.

UI MeSH Term Description Entries
D007700 Kinetics The rate dynamics in chemical or physical systems.
D007854 Lead A soft, grayish metal with poisonous salts; atomic number 82, atomic weight 207.2, symbol Pb.
D002104 Cadmium An element with atomic symbol Cd, atomic number 48, and atomic weight 112.41. It is a metal and ingestion will lead to CADMIUM POISONING.
D002460 Cell Line Established cell cultures that have the potential to propagate indefinitely. Cell Lines,Line, Cell,Lines, Cell
D004247 DNA A deoxyribonucleotide polymer that is the primary genetic material of all cells. Eukaryotic and prokaryotic organisms normally contain DNA in a double-stranded state, yet several important biological processes transiently involve single-stranded regions. DNA, which consists of a polysugar-phosphate backbone possessing projections of purines (adenine and guanine) and pyrimidines (thymine and cytosine), forms a double helix that is held together by hydrogen bonds between these purines and pyrimidines (adenine to thymine and guanine to cytosine).

D004261 DNA Replication The process by which a DNA molecule is duplicated. Autonomous Replication,Replication, Autonomous,Autonomous Replications,DNA Replications,Replication, DNA,Replications, Autonomous,Replications, DNA
D006367 HeLa Cells The first continuously cultured human malignant CELL LINE, derived from the cervical carcinoma of Henrietta Lacks. These cells are used for, among other things, VIRUS CULTIVATION and PRECLINICAL DRUG EVALUATION assays. Cell, HeLa,Cells, HeLa,HeLa Cell
D013936 Thymidine A nucleoside in which THYMINE is linked to DEOXYRIBOSE. 2'-Deoxythymidine,Deoxythymidine,2' Deoxythymidine
