A panel of tests is commonly considered to comprehensively evaluate the ability of a chemical to induce …
The genotoxic substances induce damage to the genetic material in the cells through interactions with the DNA sequence and structure. For example, the transition metal chromium interacts with DNA in its high-valent oxidation state so to incur DNA lesions leading to carcinogenesis. The metastable oxidation … See more Genotoxicity is the property of chemical agents that damage the genetic information within a cell causing mutations, which may lead to cancer.

For both the DT40 parental cell line and its Rad54-/-mutant, the LD 50 of the solvent extracts increased with time during biological treatment (Fig. 5).
WebThe drugs used for the treatment and management of genotoxicity also act as anti- cancer agents, for example, alkylating agents, intercalating agents and enzyme inhibitors. Certain plant extracts such as flavonoids and ellagic acid are found to seize pharmacological activity and are being used as anti-mutagenic agents.
