Abstract:
Pesticides constitute a diverse class of chemicals used for the protection of agricultural products. Several lines of evidence demonstrate that organochlorine and organophosphate pesticides can cause malignant transformation of cells in in vitro and in vivo models. In the current minireview a comprehensive summary of recent in vitro findings is presented along with data reported from human population studies, regarding the impact of pesticide exposure on activation or dysregulation of oncogenes and tumor suppressor genes. Substantial mechanistic work suggests that pesticides are capable of inducing mutations in oncogenes and increase their transcriptional expression in vitro, whereas human population studies indicate associations between pesticide exposure levels and mutation occurrence in cancer-related genes. Further work is required to fully explore the exact mechanisms by which pesticide exposure affects the integrity and normal function of oncogenes and tumor suppressor genes in human populations.
Insights
Pesticide exposure, including organochlorine and organophosphate types, may lead to cell mutations and cancer. Research links pesticide use to oncogene and tumor suppressor gene damage in lab studies and human populations.
Area of Science:
- Environmental toxicology
- Molecular oncology
Background:
- Pesticides are widely used in agriculture.
- Organochlorine and organophosphate pesticides are linked to malignant cell transformation.
Purpose of the Study:
- To summarize recent in vitro and human population findings on pesticide exposure's impact on oncogenes and tumor suppressor genes.
- To explore the mechanisms of pesticide-induced cancer development.
Main Methods:
- Review of in vitro studies on cell transformation.
- Analysis of human population studies on pesticide exposure and cancer-related gene mutations.
Main Results:
- In vitro studies show pesticides can induce oncogene mutations and increase transcriptional expression.
- Human population studies suggest associations between pesticide exposure and mutations in cancer-related genes.
Conclusions:
- Pesticide exposure may disrupt the normal function of oncogenes and tumor suppressor genes.
- Further research is needed to elucidate the precise mechanisms in human populations.

Cancer-Critical Genes I: Proto-oncogenes
When the function of certain critical genes, especially those involved in cell cycle regulation and cell growth signaling cascades, gets disrupted, it upsets the cell cycle progression. Such cells with unchecked cell cycles start proliferating uncontrollably and eventually develop into tumors.

Cancer Therapies
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...
