Acrolein mutagenicity relies on DNA adduct formation. Reaction of acrolein with deoxyguanosine generates α-hydroxy-1, N2-propano-2′-deoxyguanosine (α-HOPdG) and γ-hydroxy-1, N2-propano-2′-deoxyguanosine (γ-HOPdG) adducts. These two DNA adducts behave differently in mutagenicity. γ-HOPdG is the major DNA adduct and it can lead to interstrand DNA-DNA and DNA-peptide/protein cross-links, which may induce strong mutagenicity; however, γ-HOPdG can be repaired by some DNA polymerases complex and… 
Mechanism of Repair of Acrolein- and Malondialdehyde-Derived Exocyclic Guanine Adducts by the α-Ketoglutarate/Fe(II) Dioxygenase AlkB
This study provides a detailed mechanism by which three-carbon bridge exocyclic guanine adducts can be processed by AlkB and suggests an important role for the AlkB family of dioxygenases in protecting against the deleterious biological consequences of acrolein and MDA.
Toxicology and risk assessment of acrolein in food.
It is concluded that a health risk seems to be unlikely of acrolein exposure via food due to analytical difficulties and the lack of reliable content measurements, and rough estimates of ac rolein exposure in the range of a few μg/kg body weight/day.
Interaction of acrylamide, acrolein, and 5-hydroxymethylfurfural with amino acids and DNA.
This work reviews the interaction pathways of three toxins with amino acids and the cytotoxicity and changes after the digestion and absorption of resulting adducts and their interaction with DNA is also discussed.
Mechanisms Underlying Acrolein-Mediated Inhibition of Chromatin Assembly
It is reported that acrolein reacts with lysine residues, including lysines 5 and 12, sites important for chromatin assembly, on histone H4 in vitro and in vivo, and prevents these sites from physiological modifications.
Genotoxicity of lipid oxidation compounds
Molecular mechanisms of acrolein toxicity: relevance to human disease.
This review addresses the current understanding of each pathogenic mechanism of acrolein toxicity, with emphasis on the known and anticipated contribution to clinical disease, and potential therapies.
Acrolein measurement and degradation in Dulbecco’s Modified Eagle Medium: an examination of in-vitro exposure metrics
This work characterized the half-life of acrolein in culture medium to ascertain the plausible exposure window and demonstrated accelerated depletion over time at room temperature, and faster still at 37 °C.
Differences in susceptibility to inactivation of human aldehyde dehydrogenases by lipid peroxidation byproducts.
It was determined that, among the three most studied human ALDH isoforms, ALDH2 showed the highest catalytic efficiency for oxidation of acrolein, 4-hydroxy-2-nonenal (4-HNE), and malondialdehyde, and it was suggested that both binding sites, those for aldehyde and NAD(+) in AL DH2, are targets for the inactivation by lipid peroxidation products.
Thermally induced process-related contaminants: the example of acrolein and the comparison with acrylamide: opinion of the Senate Commission on Food Safety (SKLM) of the German Research Foundation (DFG).
First observations indicate that human exposure to AC may be higher than the exposure to AA, and current knowledge on formation, occurrence, exposure, metabolism, biological effects, toxicity, and carcinogenicity is low.


Mutagenesis by acrolein-derived propanodeoxyguanosine adducts in human cells.
Results indicate that the minor alpha-OH-PdG adduct is more genotoxic than the major gamma- OH-P dG, and experiments using a HeLa whole cell extract indicate that all three DNA adducts are not efficiently removed from DNA by base excision repair.
Comparative Evaluation of the Bioreactivity and Mutagenic Spectra of Acrolein-Derived α-HOPdG and γ-HOPdG Regioisomeric Deoxyguanosine Adducts
A comparative investigation has assessed the ability of each adduct to undergo secondary chemical reactions with biomolecules to form various cross-linked species, in vitro translesion DNA synthesis, and mutagenic properties, following replication in mammalian cells.
Mutagenicity and sequence specificity of acrolein-DNA adducts.
It is confirmed that Acr-dG adducts are mutagenic and support the hypothesis that acrolein is a major etiological agent for CS and cooking fume-related lung cancer.
Responses to the Major Acrolein-derived Deoxyguanosine Adduct inEscherichia coli *
Nucleotide excision repair, recombination repair, and highly accurate translesion synthesis combine to protect E. coli from the potential genotoxicity of this DNA adduct.
Lack of mutagenicity of acrolein-induced DNA adducts in mouse and human cells.
It is concluded that acrolein is not mutagenic to mouse and human fibroblasts, regardless of DNA repair capacity or methylation status of CpGs, possibly because of a highly accurate replication bypass of the induced lesions.
Comparative evaluation of the bioreactivity and mutagenic spectra of acrolein-derived alpha-HOPdG and gamma-HOPdG regioisomeric deoxyguanosine adducts.
Cellular replication and mutagenesis assays in COS-7 cells using single-stranded DNA containing a site specific alpha-HOPdG revealed that this adduct was significantly mutagenic, yielding a nearly identical frequency and spectrum of mutations as compared with the gamma-HopdG adduct.
Evaluation of the Mutagenic Potential of the Principal DNA Adduct of Acrolein*
Acrolein is produced extensively in the environment by incomplete combustion of organic materials, and it arises endogenously in humans as a metabolic by-product. Acrolein reacts with DNA at guanine
Error Prone Translesion Synthesis Past γ-Hydroxypropano Deoxyguanosine, the Primary Acrolein-derived Adduct in Mammalian Cells*
In vitro γ-HOPdG strongly blocks DNA synthesis by two major polymerases, pol δ and pol ε, and could be diminished by the addition of proliferating cell nuclear antigen, leading to highly mutagenic translesion bypass across this adduct.
Genotoxic mechanism for the major acrolein-derived deoxyguanosine adduct in human cells.
The authentic major adduct, gamma-OH-PdG, is less blocking to DNA synthesis and less miscoding than the modelAdduct, PdG.
Formation of cyclic deoxyguanosine adducts in Chinese hamster ovary cells by acrolein and crotonaldehyde.
Persistence studies showed that adduct levels were unchanged if the cells were cultured for 6 h before DNA isolation, and 32P-Postlabeling analysis confirmed the presence of adducts in crotonaldehyde-treated cells.
