Summary
This study investigated the genotoxic effects of cyfluthrin, a common insecticide. Cyfluthrin induced chromosomal aberrations and micronucleus formation in vitro and in vivo, indicating potential genotoxicity despite low animal toxicity.
Area of Science:
- Toxicology
- Genetics
- Environmental Science
Background:
- Cyfluthrin is a widely used synthetic pyrethroid insecticide with broad-spectrum activity and low animal toxicity.
- Limited data exists regarding the genotoxic potential of cyfluthrin, necessitating further investigation.
Purpose of the Study:
- To evaluate the in vitro and in vivo genotoxic effects of cyfluthrin.
- To assess cyfluthrin's potential to induce gene mutation, chromosomal aberrations, sister chromatid exchange, and micronucleus formation.
Main Methods:
- In vitro: Ames test, chromosomal aberration (CA), sister chromatid exchange (SCE), and micronucleus (MN) assays in human lymphocytes.
- In vivo: CA and cytotoxicity assays in rat bone-marrow cells following oral or intraperitoneal administration.
Main Results:
- Cyfluthrin did not significantly increase gene mutations or SCE frequency.
- Significant increases in CA and MN formation were observed in vitro after 48-hour treatment.
- In vivo, cyfluthrin significantly increased CA in rat bone-marrow cells across all tested doses and administration routes.
Conclusions:
- Cyfluthrin exhibits genotoxic potential, inducing chromosomal damage in vitro and in vivo.
- Cytotoxicity was observed in vitro and in vivo, particularly at higher concentrations and longer exposure times.
- Further research is warranted to fully understand the long-term genotoxic risks associated with cyfluthrin exposure.

01:25Mutagenicity and Carcinogenicity
Mutagenicity and carcinogenicity refer to the ability of drugs to cause genetic defects and induce cancer, respectively. The International Agency for Research on Cancer (IARC) classifies agents into four groups based on their carcinogenic potential. Group 1 agents are known human carcinogens; group 2A agents are probably carcinogenic to humans; group 3 agents lack data to support their role in carcinogenesis; and group 4 includes agents for which data support that they are not likely to be...
01:11Pharmacogenetics of Drug Targets: β₂-Adrenergic Receptors, Apo E, Thymidylate Synthase
Genetic polymorphisms in drug targets have emerged as critical determinants of interindividual variability in drug response and toxicity. Pharmacogenomic investigations increasingly focus on identifying these variations to personalize and optimize therapeutic interventions. A drug target may be a receptor, enzyme, or signaling protein involved in pharmacologic responses or disease-related pathways. While early pharmacogenetic studies focused primarily on drug metabolism, current research...
01:07Teratogenicity
The ability of a drug to produce structural deformations and functional abnormalities in the developing embryo or the fetus is called teratogenicity, and the drug producing this effect is known as a teratogen. Teratogenic effects include stillbirth, miscarriage, intrauterine growth restriction, and neurocognitive delay. A teratogen may affect the embryo at different stages of development, which is important in determining the type and extent of the damage. During blastocyst formation, the early...
01:24Drug Toxicity: Dose-Dependent Reactions
Drug toxicities can be stratified into pharmacological, pathological, or genotoxic based on their mechanisms. The incidence and severity of these toxicities generally increase with the drug's concentration in the body and exposure time.Pharmacological toxicity is evident when the therapeutic effects of drugs overshoot into adverse reactions in a predictable, dose-dependent manner. Central nervous system (CNS) depression from barbiturates is a classic example, with effects escalating from...
01:16In vitro Mutagenesis
To learn more about the function of a gene, researchers can observe what happens when the gene is inactivated or “knocked out,” by creating genetically engineered knockout animals. Knockout mice have been particularly useful as models for human diseases such as cancer, Parkinson’s disease, and diabetes.
