689 rows · NTP performs toxicology/carcinogenicity studies to address the gap in knowledge concerning the toxicity of substances in our environment. These studies are also performed to evaluate dose-response relationships between exposed and unexposed organisms and to determine if a substance elicits toxic effects and/or causes cancer in a biological system.

Carcinogen - Wikipedia

★ ★ ★ ★ ★

A carcinogen is any substance, radionuclide, or radiation that promotes carcinogenesis, the formation of cancer.This may be due to the ability to damage the genome or to the disruption of cellular metabolic processes. Several radioactive substances are considered carcinogens, but their carcinogenic activity is attributed to the radiation, for example gamma rays and alpha particles, which they ...

Carcinogenicity Study - NAMSA

★ ★ ★ ★ ☆

Carcinogenicity studies are performe to assess the potential of a device material to incite the growth of malignant cells. ISO describes carcinogenicity testing as the means “to determine the tumorigenic potential of devices, materials, and/or extracts to either a single or multiple exposures over a period of the total life-span of the test animal.”

In a previous carcinogenicity study using F344 rats, the incidences of Leydig cell tumors in the 100 and 500 ppm groups was significantly increased (Sunahara et al., 1993). In another study using SD rats, Leydig cell tumors were not found in rats treated with 3-MCPD for 72 weeks (Weisburger et al., 1981).

Carcinogenicity study of cholestyramine, an anti-hypercholesterolemic agent, was carried out by feeding B6C3F1 mice of both sexes with the pellet diet in which cholestyramine was admixed at the rates of 1.25, 2.5 and 5%. The animals were fed on the drug-admixed diet for 18 months and on a normal diet for subsequent 3 months.

Certain animal health features are monitored throughout the study, but the key assessment resides in the full pathological analysis of the animal tissues and organs when the study is terminated. Two endpoints in animal bioassays, carcinogenicity and chronic toxicity, can be combined to reduce animal use, as described in OECD TG 453.

Citoxlab carcinogenicity studies comply with international guidelines and regulations, such as EU (CPMP), ICH, FDA, EPA, JMHW, JMAFF and OECD. Recommended requirements are similar for all these guidelines, although for agrochemicals and industrial chemicals we can combine one of the carcinogenicity studies with a long-term chronic toxicity study.
