Mechanism of EtO carcinogenesis
Absorption and distribution
The main route of exposure to EtO is through inhalation, since this toxic chemical is a gas. After inhalation, EtO reaches the bloodstream and can circulate quickly throughout the body, reaching multiple organs, including the bone marrow, lymphatic tissue, and breast tissue.
EtO reactivity and carcinogenicity
As an alkylating agent, EtO doesn't need metabolic activation to cause harmful effects. It reacts directly with the DNA, RNA, and proteins. Some of the toxic chemical is detoxified by enzymes, but significant amounts still escape this mechanism. After binding to DNA, EtO interferes with replication, and if the DNA's repair systems fail to correct the damage, the mutations persist.
Chromosomal damage and epigenetic alterations
Beyond mutations, EtO exposure also causes chromosomal aberrations, including sister chromatid exchanges, micronuclei formation, and abnormal chromosome numbers (aneuploidy). This genomic issue is linked to blood cancers such as leukemia and lymphoma. EtO may also cause epigenetic alterations that interfere with DNA repair genes and accelerate carcinogenesis.
