Abstract
O-Acetyl 1,3-propanediol serves as an acrolein proelectrophile in π-allyliridium-C,O-benzoate-catalyzed carbonyl allylations mediated by racemic α-substituted allylic acetates. Using the iridium catalyst modified by (R)-SEGPHOS, a variety of 3-hydroxy-1,5-hexadienes are formed with uniformly high levels of regio-, anti-diastereo-, and enantioselectivity.

Abstract
The first systematic study of catalytic enantioselective 1,2-additions to acrolein is described. Specifically, using allyl alcohol as a tractable, inexpensive acrolein proelectrophile, iridium-catalyzed acrolein allylation is achieved with high levels of regio-, anti-diastereo-, and enantioselectivity. This process delivers 3-hydroxy-1,5-hexadienes, a useful compound class that is otherwise challenging to access via enantioselective catalysis. Two-fold use of this method unlocks concise total syntheses of amphidinolide R (9 vs 23 steps, LLS) and amphidinolide J (9 vs 23 or 26 steps, LLS), which are prepared in fewer than half the steps previously possible, and the first total synthesis of amphidinolide S (10 steps, LLS).

Abstract
Characterization of the chemistry, structure, formation, and metabolism of DNA adducts has been one of the most significant contributions to the field of chemical toxicology. This work provides the foundation to develop analytical methods to measure DNA adducts, define their relationship to disease, and establish clinical tests. Monitoring exposure to environmental and endogenous toxicants can predict, diagnose, and track disease as well as guide therapeutic treatment. DNA adducts are one of the most promising biomarkers of toxicant exposure owing to their stability, appearance in numerous biological matrices, and characteristic analytical properties. In addition, DNA adducts can induce mutations to drive disease onset and progression and can serve as surrogate markers of chemical exposure. In this perspective, we highlight significant advances made within the past decade regarding DNA adduct quantitation using mass spectrometry. We hope to expose a broader audience to this field and encourage analytical chemistry laboratories to explore how specific adducts may be related to various pathologies. One of the limiting factors in developing clinical tests to measure DNA adducts is cohort size; ideally, the cohort would allow for model development and then testing of the model to the remaining cohort. The goals of this perspective article are to (1) provide a summary of analyte levels measured using state-of-the-art analytical methods, (2) foster collaboration, and (3) highlight areas in need of further investigation.

Abstract
Five hundred seventy CD-1 mice were divided equally by gender and assigned to three groups of 70 per gender and one group of 75 per gender. The first three groups were dosed via oral intubation at 0, 0.5, and 2.0 mg/kg/day while the larger groups were dosed at 4.5 mg/kg/day. Observations were made twice daily and blood smears taken at 12 and 18 months. All animals were sacrificed at 18 months; organs were weighed and examined grossly and microscopically. Treated animals showed decreased body weight gain and male mice demonstrated increased mortality, particularly at the high-dose level. Gross and microscopic lesions were not obviously dose dependent. In this study, acrolein was not shown to have oncogenic properties.

Abstract
Humans are continuously exposed to hazardous chemicals in the environment. These chemicals or their electrophilic metabolites can form adducts with genomic DNA, which can lead to mutations and the initiation of cancer. The identification of DNA adducts is required for understanding exposure and the etiological role of a genotoxic chemical in cancer risk. The analytical chemist is confronted with a great challenge because the levels of DNA adducts generally occur at <1 adduct per 10(7) nucleotides, and the amount of tissue available for measurement is limited. Ion trap mass spectrometry has emerged as an important technique to screen for DNA adducts because of the high level sensitivity and selectivity, particularly when employing multi-stage scanning (MS(n) ). The product ion spectra provide rich structural information and corroborate the adduct identities even at trace levels in human tissues. Ion trap technology represents a significant advance in measuring DNA adducts in humans. © 2016 by John Wiley & Sons, Inc.

Abstract
High density lipoproteins (HDL) are considered athero-protective, primarily due to their role in reverse cholesterol transport, where they transport cholesterol from peripheral tissues to the liver for excretion. The current study was designed to determine the impact of HDL modification by acrolein, a highly reactive aldehyde found in high abundance in cigarette smoke, on the cholesterol transport functions of HDL. HDL was chemically-modified with acrolein and immunoblot and mass spectrometry analyses confirmed apolipoprotein crosslinking, as well as acrolein adducts on apolipoproteins A-I and A-II. The ability of acrolein-modified HDL (acro-HDL) to serve as an acceptor of free cholesterol (FC) from COS-7 cells transiently expressing SR-BI was significantly decreased. Further, in contrast to native HDL, acro-HDL promotes higher neutral lipid accumulation in murine macrophages as judged by Oil Red O staining. The ability of acro-HDL to mediate efficient selective uptake of HDL-cholesteryl esters (CE) into SR-BI-expressing cells was reduced compared to native HDL. Together, the findings from our studies suggest that acrolein modification of HDL produces a dysfunctional particle that may ultimately promote atherogenesis by impairing functions that are critical in the reverse cholesterol transport pathway.

Abstract
OBJECTIVE Acrolein is a hazardous air pollutant. Tobacco smoke and indoor air pollution are the main causes of human exposure. Acrolein has been shown to cause cytotoxicity in the airways and induce inflammation and mucin production in pulmonary cells. We investigated whether acrolein caused cytotoxicity, induced inflammation or increased expression of mucin in immortalized human middle ear epithelial cell lines (HMEECs). METHODS Cytotoxicity following acrolein treatment was investigated using the MTT assay, flow cytometry, and Hoechst 33342 staining of HMEECs. We measured expression of inflammatory cytokines tumor necrosis factor (TNF)-α and cyclo-oxygenase (COX)-2 and the mucin gene MUC5AC using semi-quantitative real-time reverse transcriptase polymerase chain reaction (RT-PCR) and Western blotting. RESULTS Exposure to >50 μg/mL acrolein caused a decrease in cell viability. Acrolein induced apoptosis and necrosis at 50 μg/mL. Acrolein at 5-50 μg/mL increased expression of TNF-α and COX-2, as shown by RT-PCR and Western blotting. Acrolein exposure at 5-50 μg/mL for 2-24h increased MUC5AC expression, as determined by RT-PCR. CONCLUSION Acrolein decreased cell viability, induced an inflammatory response, and increased mucin gene expression in HMEECs. These findings support the hypothesis that acrolein, a hazardous air pollutant in tobacco smoke and ambient air, is a risk factor for otitis media.

Abstract
Here, we review current evidence pointing to the function of VDAC1 in cell life and death, and highlight these functions in relation to cancer. Found at the outer mitochondrial membrane, VDAC1 assumes a crucial position in the cell, controlling the metabolic cross-talk between mitochondria and the rest of the cell. Moreover, its location at the boundary between the mitochondria and the cytosol enables VDAC1 to interact with proteins that mediate and regulate the integration of mitochondrial functions with other cellular activities. As a metabolite transporter, VDAC1 contributes to the metabolic phenotype of cancer cells. This is reflected by VDAC1 over-expression in many cancer types, and by inhibition of tumor development upon silencing VDAC1 expression. Along with regulating cellular energy production and metabolism, VDAC1 is also a key protein in mitochondria-mediated apoptosis, participating in the release of apoptotic proteins and interacting with anti-apoptotic proteins. The involvement of VDAC1 in the release of apoptotic proteins located in the inter-membranal space is discussed, as is VDAC1 oligomerization as an important step in apoptosis induction. VDAC also serves as an anchor point for mitochondria-interacting proteins, some of which are also highly expressed in many cancers, such as hexokinase (HK), Bcl2, and Bcl-xL. By binding to VDAC, HK provides both metabolic benefit and apoptosis-suppressive capacity that offers the cell a proliferative advantage and increases its resistance to chemotherapy. VDAC1-based peptides that bind specifically to HK, Bcl2, or Bcl-xL abolished the cell’s abilities to bypass the apoptotic pathway. Moreover, these peptides promote cell death in a panel of genetically characterized cell lines derived from different human cancers. These and other functions point to VDAC1 as a rational target for the development of a new generation of therapeutics.

Abstract
Exocyclic DNA adducts, including 1,N(2)-propano-2'-deoxyguanosine derived from acrolein (AdG) and crotonaldehyde (CdG) and the three lipid peroxidation-related etheno adducts 1,N(6)-etheno-2'-deoxyadenosine (εdAdo), 3,N(4)-etheno-2'-deoxycytidine (εdCyt), and 1,N(2)-etheno-2'-deoxyguanosine (1,N(2)-εdGuo), play an important role in cancer formation and they are associated with oxidative-stress-induced DNA damage. Saliva is an easily accessible and available biological fluid and a potential target of noninvasive biomarkers. In this study, a highly sensitive and specific assay based on isotope dilution nanoflow LC-nanospray ionization tandem mass spectrometry (nanoLC-NSI/MS/MS) is developed for simultaneous detection and quantification of these five adducts in human salivary DNA. The levels of AdG, CdG, εdAdo, εdCyd, and 1,N(2)-εdGuo, measured in 27 human salivary DNA samples from healthy volunteers, were determined as 104 ± 50, 7.6 ± 12, 99 ± 50, 72 ± 49, 391 ± 198 (mean ± SD) in 10(8) normal nucleotides, respectively, starting with 25 μg of DNA isolated from an average of 3 mL of saliva. Statistically significant correlations were found between levels of εdAdo and εdCyd (γ = 0.8007, p < 0.0001), between levels of εdAdo and 1,N(2)-εdGuo (γ = 0.6778, p = 0.0001), between levels of εdCyd and 1,N(2)-εdGuo (γ = 0.5643, p = 0.0022), between levels of AdG and 1,N(2)-εdGuo (γ = 0.5756, p = 0.0017), and between levels of AdG and εdAdo (γ = 0.3969, p = 0.0404). Only 5 μg of DNA sample was analyzed for simultaneous quantification of these adducts. The easy accessibility and availability of saliva and the requirement for the small amount of DNA samples make this nanoLC-NSI/MS/MS assay clinically feasible in assessing the possibility of measuring 1,N(2)-propano-2'-deoxyguanosine and etheno adducts levels in human salivary DNA as noninvasive biomarkers for DNA damage resulting from oxidative stress and for evaluating their roles in cancer formation and prevention.

Abstract
Two stable isotope dilution assays were developed for the quantitation of acrolein in fats and oils using [(13)C(3)]-acrolein as the internal standard. First, a direct GC-MS headspace method, followed by an indirect GC-MS method using derivatization with pentafluorophenyl hydrazine, was established. Analysis of six different types of oils varying in their pattern of fatty acids showed significant differences in the amounts of acrolein formed after heating at various temperatures and for various times. For example, after 24 h at 140 °C, coconut oil contained 6.7 mg/kg, whereas linseed oil was highest with 242.3 mg/kg. A comparison of the results showed that the extent of acrolein formation seemed to be correlated with the amount of linolenic acid in the oils. Although the acrolein concentrations were lowered in all six oils after frying of potato crisps, linseed and rapeseed oil still contained the highest amounts of acrolein after frying. By applying both methods on different thermally treated fats and oils, nearly identical quantitative data were obtained.

Abstract
An integral membrane protein, Claudin 5 (CLDN5), is a critical component of endothelial tight junctions that control pericellular permeability. Breaching of endothelial barriers is a key event in the development of pulmonary edema during acute lung injury (ALI). A major irritant in smoke, acrolein can induce ALI possibly by altering CLDN5 expression. This study sought to determine the cell signaling mechanism controlling endothelial CLDN5 expression during ALI. To assess susceptibility, 12 mouse strains were exposed to acrolein (10 ppm, 24 h), and survival monitored. Histology, lavage protein, and CLDN5 transcripts were measured in the lung of the most sensitive and resistant strains. CLDN5 transcripts and phosphorylation status of forkhead box O1 (FOXO1) and catenin (cadherin-associated protein) beta 1 (CTNNB1) proteins were determined in control and acrolein-treated human endothelial cells. Mean survival time (MST) varied more than 2-fold among strains with the susceptible (BALB/cByJ) and resistant (129X1/SvJ) strains (MST, 17.3 ± 1.9 h vs. 41.4 ± 5.1 h, respectively). Histological analysis revealed earlier perivascular enlargement in the BALB/cByJ than in 129X1/SvJ mouse lung. Lung CLDN5 transcript and protein increased more in the resistant strain than in the susceptible strain. In human endothelial cells, 30 nM acrolein increased CLDN5 transcripts and increased p-FOXO1 protein levels. The phosphatidylinositol 3-kinase inhibitor LY294002 diminished the acrolein-induced increased CLDN5 transcript. Acrolein (300 nM) decreased CLDN5 transcripts, which were accompanied by increased FOXO1 and CTNNB1. The phosphorylation status of these transcription factors was consistent with the observed CLDN5 alteration. Preservation of endothelial CLDN5 may be a novel clinical approach for ALI therapy.

Abstract
Acrolein, a cell metabolic product and main component of cigarette smoke, reacts with DNA generating alpha-OH-PdG lesions, which have the ability to pair with dATP during replication thereby causing G to T transversions. We describe the solution structure of an 11-mer DNA duplex containing the mutagenic alpha-OH-PdG.dA base pair intermediate, as determined by solution nuclear magnetic resonance (NMR) spectroscopy and retrained molecular dynamics (MD) simulations. The NMR data support a mostly regular right-handed helix that is only perturbed at its center by the presence of the lesion. Undamaged residues of the duplex are in anti orientation, forming standard Watson-Crick base pairs alignments. Duplication of proton signals at and near the damaged base pair reveals the presence of two enantiomeric duplexes, thus establishing the exocyclic nature of the lesion. The alpha-OH-PdG adduct assumes a syn conformation pairing to its partner dA base that is protonated at pH 6.6. The three-dimensional structure obtained by restrained molecular dynamics simulations show hydrogen bond interactions that stabilize alpha-OH-PdG in a syn conformation and across the lesion containing base pair. We discuss the implications of the structures for the mutagenic bypass of acrolein lesions.

Abstract
Humans are exposed to acrolein and crotonaldehyde due to environmental pollution and endogenous lipid peroxidation. These aldehydes react with the 2'-deoxyguanosine moiety of DNA, forming the exocyclic 1,N2-propano-2'-deoxyguanosine adducts AdG and CdG. These adducts are mutagenic lesions, and they play an important role in cancer and neurodegenerative diseases. In this study, a highly sensitive and quantitative assay was developed for simultaneous detection and quantification of AdG and CdG isomers in human placenta and leukocyte DNA by isotope dilution nanoflow LC with nanospray ionization tandem mass spectrometry (nanoLC-NSI/MS/MS). The on-column detection limits (S/N > or = 3) of AdG and CdG were 15 and 8.9 amol, respectively. The quantification limits of AdG and CdG for the entire assay were 619 and 297 amol, respectively, corresponding to 9.8 and 4.7 adducts in 10(9) normal nucleotides, respectively, starting with 20 microg of DNA. Different enzyme hydrolysis methods were compared, and the optimal hydrolysis conditions were employed for the assay. Levels of AdG and CdG in human placental DNA (20 microg) were 108 and 26 in 10(8) normal nucleotides, respectively, with the respective relative standard deviation (RSD) of 2.6% and 3.1% (n = 3). Levels of AdG and CdG in 9 human leukocyte DNA samples were 78 +/- 23 (mean +/- SD) and 6.2 +/- 3.8 (mean +/- SD) in 10(8) normal nucleotides, respectively, starting from 30 microg of DNA. Using this assay, only 4-6 microg of DNA sample was subjected to this nanoLC-NSI/MS/MS system for analysis. Only 1-1.5 mL of blood is needed for measuring AdG and CdG levels in leukocyte DNA. Thus, it is clinically feasible using this highly sensitive assay to investigate the potential of using these adducts as noninvasive biomarkers for DNA damage resulting from acrolein and crotonaldehyde and to study their roles in cancer development and prevention.

Abstract
Acrolein and 4-hydroxy-2-nonenal (HNE) are byproducts of lipid peroxidation and are thought to play central roles in various traumatic injuries and disease states that involve cellular oxidative stress, for example, spinal cord trauma, diabetes, and Alzheimer's disease. In this review, we will discuss the chemical attributes of acrolein and HNE that determine their toxicities. Specifically, these aldehydes are classified as type 2 alkenes and are characterized by an alpha,beta-unsaturated carbonyl structure. This structure is a conjugated system that contains mobile pi-electrons. The carbonyl oxygen atom is electronegative and can promote the withdrawal of mobile electron density from the beta-carbon atom causing regional electron deficiency. On the basis of this type of electron polarizability, both acrolein and HNE are considered to be soft electrophiles that preferentially form 1,4-Michael type adducts with soft nucleophiles. Proteomic, quantum mechanical, and kinetic data will be presented, indicating that cysteine sulfhydryl groups are the primary soft nucleophilic targets of acrolein and HNE. This is in contrast to nitrogen groups on harder biological nucleophiles such as lysine or histidine residues. The toxicological outcome of adduct formation is not only dependent upon residue selectivity but also the importance of the targeted amino acid in protein function or structure. In attempting to discern the toxicological significance of a given adduct, we will consider the normal roles of cysteine, lysine, and histidine residues in proteins and the relative merits of corresponding adducts in the manifestations of diseases or toxic states. Understanding the molecular actions of acrolein and HNE could provide insight into many pathogenic conditions that involve initial cellular oxidative stress and could, thereby, offer new efficacious avenues of pharmacological defense.

Abstract
RATIONALE Induced mainly by cigarette smoking, chronic obstructive pulmonary disease (COPD) is a global public health problem characterized by progressive difficulty in breathing and increased mucin production. Previously, we reported that acrolein levels found in COPD sputum could activate matrix metalloproteinase-9 (MMP9). OBJECTIVES To determine whether acrolein increases expression and activity of MMP14, a critical membrane-bound endopeptidase that can initial a MMP-activation cascade. METHODS MMP14 activity and adduct formation were measured following direct acrolein treatment. MMP14 expression and activity was measured in human airway epithelial cells. MMP14 immunohistochemistry was performed with COPD tissue, and in acrolein- or tobacco-exposed mice. MEASUREMENTS AND MAIN RESULTS In a cell-free system, acrolein, in concentrations equal to those found in COPD sputum, directly adducted cysteine 319 in the MMP14 hemopexin-like domain and activated MMP14. In cells, acrolein increased MMP14 activity, which was inhibited by a proprotein convertase inhibitor, hexa-d-arginine. In the airway epithelium of COPD subjects, immunoreactive MMP14 protein increased. In mouse lung, acrolein or tobacco smoke increased lung MMP14 activity and protein. In cells, acrolein-induced MMP14 transcripts were inhibited by an epidermal growth factor receptor (EGFR) neutralizing antibody, EGFR kinase inhibitor, metalloproteinase inhibitor, or mitogen-activated protein kinase (MAPK) 3/2 or MAPK8 inhibitors, but not a MAPK14 inhibitor. Decreasing the MMP14 protein and activity in vitro by small interfering (si)RNA to MMP14 diminished the acrolein-induced MUC5AC transcripts. In acrolein-exposed mice or transgenic mice with lung-specific transforming growth factor-alpha (an EGFR ligand) expression, lung MMP14 and MUC5AC levels increased and these effects were inhibited by a EGFR inhibitor, erlotinib. CONCLUSIONS Taken together, these findings implicate acrolein-induced MMP14 expression and activity in mucin production in COPD.

Abstract
Acrolein is a cell metabolic product and a main component of cigarette smoke. Its reaction with DNA produces two guanine lesions γ-OH-PdG, a major adduct that is nonmutagenic in mammalian cells, and the positional isomer α-OH-PdG. We describe here the solution structure of a short DNA duplex containing a single α-OH-PdG lesion, as determined by solution NMR spectroscopy and restrained molecular dynamics simulations. The spectroscopic data show a mostly regular right-handed helix, locally perturbed at its center by the presence of the lesion. All undamaged residues of the duplex are in anti orientation, forming standard Watson–Crick base-pair alignments. Duplication of proton signals near the damaged site differentiates two enantiomeric duplexes, thus establishing the exocyclic nature of the lesion. At the lesion site, α-OH-PdG rotates to a syn conformation, pairing to its counter cytosine residue that is protonated at pH 5.9. Three-dimensional models produced by restrained molecular dynamics simulations show different hydrogen-bonding patterns between the lesion and its cytosine partner and identify further stabilization of α-OH-PdG in a syn conformation by intra-residue hydrogen bonds. We compare the α-OH-PdG•dC duplex structure with that of duplexes containing the analogous lesion propano-dG and discuss the implications of our findings for the mutagenic bypass of acrolein lesions.

Abstract
Lipid peroxidation products contribute to protein aggregation that occurs during oxidative stress in a number of degenerative disorders. Acrolein (ACR), a highly toxic lipid peroxidation aldehyde, is a strong cross-linking agent of cellular components such as proteins. To understand the mechanisms of oxidative stress-induced protein aggregation, this study characterized the ACR modification of chain B from bovine insulin by mass spectrometry. To identify the cross-linking sites, the ACR-treated peptide was digested with a protease and the resulting peptides were analysed by liquid chromatography-tandem mass spectrometry. Inter- and intra-molecular cross-linking adducts were identified between amino groups and the side chain of histidine in the peptide. These results indicated that the ACR-induced cross-links were accompanied by two reactions, namely Michael addition and Schiff base formation. In conclusion, the use of mass spectrometric techniques provided chemical evidence for protein cross-linking with ACR.

Abstract
Acrolein, an important industrial chemical and environmental contaminant, has been shown to interact with nucleic acids in vitro and in vivo. In this study, we examined the reactivity of acrolein towards thymidine and calf-thymus double- and single-stranded DNA in aqueous buffered solutions. LC-MS Analyses of the reaction mixture of acrolein with thymidine showed the formation of five structurally different adducts. The structures of the products were determined on the basis of mass spectrometry, UV absorbance, and (1)H- and (13)C-NMR spectroscopy. The adducts were identified as 3-(3-oxopropyl)thymidine (dT1), 3-[(tetrahydro-2,4-dihydroxypyran-3-yl)methyl]thymidine (dT2), 2-(hydroxymethyl)-5-(thymidin-3-yl)pent-2-enal (dT3), 3-hydroxy-2-methylidene-5-(thymidin-3-yl)pentanal (dT4), and 2-[(thymidin-3-yl)methyl]penta-2,4-dienal (dT5). The adducts dT2-dT5 were formed in reaction of dT1 with acrolein. In the reaction of acrolein with calf-thymus DNA, dT1 was the only adduct detected in the DNA hydrolysate.

Abstract
Acrolein, which is a highly reactive alpha,beta-unsaturated aldehyde generated by lipid peroxidation, can affect cells and tissues and cause various disorders. Increased levels of unsaturated aldehydes play an important role in the pathogenesis of a number of human diseases such as Alzheimer's disease, atherosclerosis and diabetes. Acrolein is a highly ubiquitous toxic environmental pollutant. Because of human exposure, there is a need for investigating the mechanisms involved in acrolein toxicity at the cellular and molecular levels. Acrolein can induce cell death by apoptosis, although the mechanisms are not entirely clear. The present study investigates whether mitogen-activated protein kinases (MAPKs) play a role in activation of apoptosis by acrolein. Our findings show that acrolein-mediated apoptosis is in fact MAPK-dependent in Chinese hamster ovary cells. The MAP family kinases, including ERK and p38 kinase, and the transcription factor c-Jun were all activated by phosphorylation after 1 h exposure to acrolein. Phosphorylation of ERK and p38 kinases and their blockade by an ERK inhibitor, U0126, or a p38 inhibitor, SB203580, respectively, suggested that activation of apoptosis by acrolein is ERK- and p38-dependent. Thus, blockade of ERK and p38 inhibited chromatin condensation, caspase-7 and -9 activation as well as ICAD cleavage induced by acrolein. JNK and AKT kinases seem to be implicated in survival pathways against acrolein insult, since their respective inhibitors, SP600125 and LY294002/Wortmannin switched the mode of cell death from apoptosis to total necrosis. Finally, acrolein induced phosphorylation of the pro-apoptotic factor p53 which is responsible for transcription of pro-apoptotic factors such as Bax and Fas ligand. These results provide new information demonstrating the implication of MAPKs and AKT in acrolein-induced apoptosis, and this information may be useful for understanding the pathogenesis of a number of tissue diseases and environmental toxicity in response to acrolein.

Abstract
Acrolein, a widely distributed environmental pollutant, reacts with dGuo in DNA to form two pairs of 1,N2-propano-dGuo adducts: (6R/S)-3-(2'-deoxyribos-1'-yl)-5,6,7,8-tetrahydro-6-hydroxypyrimido[1,2-a]purine-10(3H)one (alpha-OH-Acr-dGuo) and (8R/S)-3-(2'-deoxyribos-1'-yl)-5,6,7,8-tetrahydro-8-hydroxypyrimido[1,2-a]purine-10(3H)one (gamma-OH-Acr-dGuo). alpha-OH-Acr-dGuo is more mutagenic and mainly induces G --> T transversions. A recent study demonstrated that acrolein-DNA adducts are preferentially formed in p53 mutational hotspots in human lung cancer, but there are no reports on the presence of these adducts in the human lung. To directly investigate this question, we have developed a sensitive and specific liquid chromatography-electrospray ionization-tandem mass spectrometry (LC-ESI-MS/MS) method for the quantitative analysis of Acr-dGuo adducts in DNA. Our method is based on the enzymatic hydrolysis of DNA isolated from the human lung in the presence of [13C10,15N5]Acr-dGuo as internal standards. Acr-dGuo adducts are enriched from the hydrolysates by solid-phase extraction and analyzed by LC-ESI-MS/MS using selected reaction monitoring. The method is accurate and precise, and the identity of the adducts was confirmed by monitoring different transitions from the same parent ion and by carrying out reactions with NaOH and NaBH4, which produced N2-(3-hydroxypropyl)-dGuo or 1,N2-(1,3-propano)-dGuo from gamma-OH-Acr-dGuo and alpha-OH-Acr-dGuo, respectively. Thirty DNA samples from lung tissue were analyzed, and Acr-dGuo adducts were detected in all samples. Both alpha-OH- and gamma-OH-Acr-dGuo were observed in most of the samples; total adduct concentrations ranged from 16-209 adducts/109 nucleotides. These results demonstrate for the first time that both types of Acr-dGuo adducts are present in human lung DNA. There was no difference in adduct levels between current and ex-smokers. Collectively, the results support a plausible role for acrolein as one cause of p53 mutations in the human lung.

Abstract
Acrolein is a highly reactive alpha,beta-unsaturated aldehyde and is known to react with DNA forming exocyclic acrolein-deoxyguanosine adducts (Acro-dG). These aldehyde-DNA lesions may play a role in mutagenesis, carcinogenesis, and neurodegenerative diseases. In the present work, we described the development and evaluation of a highly sensitive and selective capillary liquid chromatography nanoelectrospray isotope dilution tandem mass spectrometry method for quantitatively analyzing Acro-dG in DNA hydrolysates. This was achieved by applying a stable isotope-labeled analogue Acro-dG-13C10,15N5 as an internal standard to the DNA to be analyzed and then hydrolyzing the DNA enzymatically to nucleosides. The acrolein-modified nucleosides were separated from normal nucleosides by capillary liquid chromatography and quantified by a high-capacity ion trap mass spectrometer in the MS/MS mode. The developed method achieved attomole-level sensitivity (limit of detection was 10 fg, 31 amol on column) for detection of pure Acro-dG adduct standards. The limit of quantification of Acro-dG adducts obtained in 10 mug of DNA hydrolysates was 1.5 fmol, which corresponded to 50 adducts/10(9) normal nucleosides. Application of this method to the analysis of Acro-dG adducts in acrolein (10-fold)-treated calf thymus DNA showed approximately 830 lesion/10(6) DNA nucleosides using as low as 50 ng of DNA. Application of this method to DNA samples (1-2 mug) isolated from brain tissues from Alzheimer's disease subjects and age-matched controls demonstrated 2800-5100 Acro-dG adducts/10(9) DNA nucleosides. Statistically significant differences (P < 0.05) in levels of Acro-dG between AD subjects and controls were observed in DNA isolated from the hippocampus/parahippocampal gyrus.

Abstract
The oxidation of spermidine or homospermidine with bovine serum amine oxidase (BSAO) was monitored in situ, using proton nuclear magnetic resonance spectroscopy in water with 10% D(2)O. NMR assignments were performed by spin decoupling and COSY spectra or by comparison with data from synthetic aminoaldehydes. The results represent the first in situ characterisation of the highly reactive aminoaldehydes and showed oxidation at the N(1) amino group of spermidine and homospermidine. Comparison of homospermidine with a variety of substrates revealed that among straight chain di- and polyamines both an aminopropyl group and two primary amino groups separated by seven (norspermidine) or eight (spermidine) carbon atoms were required for optimal substrate ability. However, highest activity was seen with the substrate N-(4-aminobutyl)hexahydropyrimidine, showing that the substrate channel of BSAO has a dual substrate preference, with moderately bulky substituents at the distal end of a diamine contributing equally well as an alkyl amino group. Cytotoxic investigations of a variety of substrates for BSAO, confirmed previous results, that cytotoxicity is primarily linked to polyamines encompassing the aminopropyl moiety. No acrolein was observed at any time during the oxidation showing that it reacts very fast with available amino groups forming a variety of derivatives.

Abstract
A sensitive and selective analytical method for the determination of acrolein in heated vegetable oils by liquid chromatographic separation with pulsed electrochemical detection is described. An optimized triple-step pulsed waveform, based on the formation/inhibition of PtOH species on the electrode surface, a consequence of the absence/presence of adsorbing analytes, is described for the sensitive detection of acrolein in acidic medium. Under these optimized experimental conditions the proposed analytical method allowed detection limits of 0.15 microM without pre- or postcolumn derivatization or tedious cleanup procedures. The proposed analytical method was successfully employed for the sensitive determination of acrolein in fresh and heated vegetable oils with good mean recoveries, selectivity, and analytical reproducibility.

Abstract
Emissions of low molecular weight aldehydes (LMWAs) from deep-frying of extra virgin olive oil, olive oil, and canola oil (control) were investigated at two temperatures, 180 and 240 degrees C, for 15 and 7 h, respectively. The oil fumes were collected in Tedlar bags and then analyzed by gas chromatography-mass spectrometry. Seven alkanals (C2-C7 and C9), eight 2-alkenals (C3-C10), and 2,4-heptadienal were found in the fumes of all three cooking oils. The generation rates of these aldehydes were found to be dependent on heating temperature, showing significant increases with increases in temperature. The LMWA emissions from both kinds of olive oils were very similar and were lower than those observed from canola oil under similar conditions. These results suggest that frying in any type of olive oil, independent of its commercial category, will effectively decrease the generation of volatile aldehydes in the exhaust. This fact is important because less expensive refined olive oil is usually used for deep-frying operations, whereas extra virgin olive oil is usually used as salad dressing.

Abstract
Acrolein, a representative carcinogenic aldehyde, that could be ubiquitously generated in biological systems under oxidative stress shows facile reactivity with a nucleophile such as a protein. In this study, to gain a better understanding of the molecular basis of acrolein modification of protein, we characterized the acrolein modification of a model peptide (the oxidized B chain of insulin) by electrospray ionization-liquid chromatography/mass spectrometry method and established a novel acrolein-lysine condensation reaction. In addition, we found that this condensation adduct represented the major antigenic adduct generated in acrolein-modified protein. To identify the modification site and structures of adducts generated in the acrolein-modified insulin B chain, both the acrolein-pretreated and untreated peptides were digested with V8 protease and the resulting peptides were subjected to electrospray ionization-liquid chromatography/mass spectrometry. This technique identified nine peptides, which contained the acrolein adducts at Lys-29 and the N terminus, and revealed that the reaction of the insulin B chain with acrolein gave multiple adducts, including an unknown adduct containing two molecules of acrolein per lysine. To identify this adduct, we incubated N(alpha)-acetyllysine with acrolein and isolated a product having the same molecular mass as the unknown acrolein-lysine adduct. On the basis of the chemical and spectroscopic evidence, the adduct was determined to be a novel pyridinium-type lysine adduct, N(epsilon)-(3-methylpyridinium)lysine (MP-lysine). The formation of MP-lysine was confirmed by amino acid analysis of proteins treated with acrolein. More notably, this condensation adduct appeared to be an intrinsic epitope of a monoclonal antibody 5F6 that had been raised against acrolein-modified protein.

Abstract
Acrolein is a representative carcinogenic aldehyde found ubiquitously in the environment and formed endogenously through oxidation reactions, such as lipid peroxidation and myeloperoxidase-catalyzed amino acid oxidation. It shows facile reactivity toward DNA to form an exocyclic DNA adduct. To verify the formation of acrolein-derived DNA adduct under oxidative stress in vivo, we raised a novel monoclonal antibody (mAb21) against the acrolein-modified DNA and found that the antibody most significantly recognized an acrolein-modified 2' -deoxyadenosine. On the basis of chemical and spectroscopic evidence, the major antigenic product of mAb21 was the 1,N6-propano-2' -deoxyadenosine adduct. The exposure of rat liver epithelial RL34 cells to acrolein resulted in a significant accumulation of the acrolein-2' -deoxyadenosine adduct in the nuclei. Formation of this adduct under oxidative stress in vivo was immunohistochemically examined in rats exposed to ferric nitrilotriacetate, a carcinogenic iron chelate that specifically induces oxidative stress in the kidneys of rodents. It was observed that the acrolein-2' -deoxyadenosine adduct was formed in the nuclei of the proximal tubular cells, the target cells of this carcinogenesis model. The same cells were stained with a monoclonal antibody 5F6 that recognizes an acrolein-lysine adduct, by which cytosolic accumulation of acrolein-modified proteins appeared. Similar results were also obtained from myeloperoxidase knockout mice exposed to the iron complex, suggesting that the myeloperoxidase-catalyzed oxidation system might not be essential for the generation of acrolein in this experimental animal carcinogenesis model. The data obtained in this study suggest that the formation of a carcinogenic aldehyde through lipid peroxidation may be causally involved in the pathophysiological effects associated with oxidative stress.

Abstract
Acrolein, a representative carcinogenic aldehyde that could be ubiquitously generated in biological systems under oxidative stress, shows facile reactivity with the epsilon-amino group of lysine to form N(epsilon)-(3-formyl-3,4-dehydropiperidino)lysine (FDP-lysine) as the major product (Uchida, K., Kanematsu, M., Morimitsu, Y., Osawa, T., Noguchi, N., and Niki, E. (1998) J. Biol. Chem. 273, 16058-16066). In the present study, we determined the electrophilic potential of FDP-lysine and established a novel mechanism of protein thiolation in which the FDP-lysine generated in the acrolein-modified protein reacts with sulfhydryl groups to form thioether adducts. When a sulfhydryl enzyme, glyceraldehyde-3-phosphate dehydrogenase, was incubated with acrolein-modified bovine serum albumin in sodium phosphate buffer (pH 7.2) at 37 degrees C, a significant loss of sulfhydryl groups, which was accompanied by the loss of enzyme activity and the formation of high molecular mass protein species (>200 kDa), was observed. The FDP-lysine adduct generated in the acrolein-modified protein was suggested to represent a thiol-reactive electrophile based on the following observations. (i) N(alpha)-acetyl-FDP-lysine, prepared from the reaction of N(alpha)-acetyl lysine with acrolein, was covalently bound to glyceraldehyde-3-phosphate dehydrogenase. (ii) The FDP-lysine derivative reacted with glutathione to form a GSH conjugate. (iii) The acrolein-modified bovine serum albumin significantly reacted with GSH to form a glutathiolated protein. Furthermore, the observation that the glutathiolated acrolein-modified protein showed decreased immunoreactivity with an anti-FDP-lysine monoclonal antibody suggested that the FDP-lysine residues in the acrolein-modified protein served as the binding site of GSH. These data suggest that thiolation of the protein-bound acrolein may be involved in redox alteration under oxidative stress, whereby oxidative stress generates the increased production of acrolein and its protein adducts that further potentiate oxidative stress via the depletion of GSH in the cells.

Abstract
This paper investigated the components, especially aldehydes, in the fume condensates from four kinds of cooking oil using ultraviolet (UV) spectrometry and gas chromatography-mass spectrometry (GC-MS). It was observed that there was a great change of the UV absorption spectra from the results of the unheated oil to the results of the fume after heat treatment (190-200, 230-240, and 270-280 degrees C). There was a strong peak within the wavelength range of 260-270 nm in each condensate sample. From the GC-MS results, it was tentatively deduced that there were some 2,4-dialkylenaldehydes and other conjugated compounds in the condensates. The results showed there were large amounts of hexanal and 2-heptenal in the cooking oil fume and that the total aldehyde peak areas of the condensates from four kinds of oil were around 30-50% of the total peak area at 270-280 degrees C.

Abstract
Acrolein, which is a highly reactive formaldehyde generated by lipid peroxidation, can affect skin and cause various disorders. The effect of exposure of human keratinocytes to acrolein on cell surface-oriented signal transduction into cells was examined. Incubation of human keratinocytes with a relatively low concentration (50 microM) of acrolein caused a prompt and selective induction of tyrosine phosphorylation of the epidermal growth factor receptor (EGFR) as a 180-kDa molecule during the period from 5-30 min after the start of incubation. This early event was followed by an increase in the density and number of phosphotyrosine-containing proteins during the period from 60-120 min after the start of incubation. The catalytic activity of EGFR as measured by the levels of autophorphorylation and phosphorylation of an exogenously added substrate, casein, in in vitro kinase assay, greatly increased as early as 1 min after the start of incubation and then decreased gradually 30 min later. MAP family kinases, including ERK, JNK, and p38 kinase, and the potentially downstream transcription factor c-Jun were all promoted for phosphorylation/activation during a period of 5-30 min. Selective prompt phosphorylation/activation of EGFR followed by phosphorylation of MAP family kinases and c-Jun and their blockade by a specific EGFR inhibitor, AG1478, suggested that activation of EGFR is the major, and possibly single, cell surface element for intracellular signal transduction in acrolein-treated cells. Incubation of human keratinocytes with 50 microM of acrolein induced atypical apoptosis with morphologic apoptotic features with low-grade oligonucleoside-sized DNA fragmentation. Partial inhibition of such a cytopathic effect of acrolein on human keratinocytes by preincubation with AG1478 suggests the involvement of an EGFR-mediated signal pathway for atypical apoptosis. These results provide new information on acrolein-induced cell surface-oriented signal transduction to human keratinocytes, and this information may be useful for understanding the pathogenesis of a number of skin diseases in response to environmental acrolein and acrolein-generating ultraviolet irradiation.

Abstract
Toxic medium chain length alkanals, alkenals, and 4-hydroxyalkenals that are generated during lipid peroxidation are potential substrates for aldehyde dehydrogenase (ALDH) isoforms. We have developed transgenic cell lines to examine the potential for either human ALDH1A1 or ALDH3A1 to protect against damage mediated by these toxic aldehydes. Using crude cytosols from stably transfected cell lines, these aldehydes were confirmed to be excellent substrates for ALDH3A1, but were poorly oxidized by ALDH1A1. Expression of ALDH3A1 by stable transfection in V79 cells conferred a high level of protection against growth inhibition by the medium-chain length aldehyde substrates with highest substrate activity, including hexanal, trans-2-hexenal, trans-2-octenal, trans-2-nonenal, and 4-hydroxy-2-nonenal (HNE). This was reflected in a parallel ability of ALDH3A1 to prevent depletion of glutathione by these aldehydes. Expression of hALDH3 completely blocked the potent induction of apoptosis by HNE in both V79 cells and in a RAW 264.7 murine macrophage cell line, consistent with the observed total prevention of HNE-protein adduct formation. Structure-activity studies indicated that the rank order of potency for the contributions of HNE functional groups to toxicity was aldehyde >/=C2=C3 double bond>>C4-hydroxyl group. Oxidation of the aldehyde moiety of HNE to a carboxyl by ALDH3A1 expressed in stably transfected cell lines drastically reduced its potency for growth inhibition and apoptosis induction. In contrast, ALDH1A1 expression provided only moderate protection against trans-2-nonenal (t2NE), and none against the other six-nine carbon aldehydes. Neither ALDH1A1 nor ALDH3A1 conferred any protection against acrolein, acetaldehyde, or chloroacetaldehyde. A small degree of protection against malondialdehyde was afforded by ALDH1A1, but not ALDH3A1. Paradoxically, cells expressing ALDH3A1 were 1.5-fold more sensitive to benzaldehyde toxicity than control V79 cells. These studies demonstrate that expression of class 3 ALDH, but not class 1 ALDH, can be an important determinant of cellular resistance to toxicity mediated by aldehydes of intermediate chain length that are produced during lipid peroxidation.

Abstract
The reduced form of glutathione (GSH) is a well-known antioxidant, while there have been few reports indicating the contribution of glutathione to protection of Escherichia coli cells from the lethal effect of oxidative damage. Here, we report that depletion of glutathione causes hypersensitivity of E. coli to acrolein, the structurally simplest alpha, beta-unsaturated aldehyde derived from lipid peroxide-degradation, and that GSH can chemically react with acrolein in vitro thus reducing its toxicity. We further demonstrated that acrolein inactivates glutathione oxidoreductase followed by depletion of glutathione, probably as a part of the toxic effect of acrolein. These results suggested that GSH contributes to cellular defense against the toxic effects.

Abstract
Lipoprotein peroxidation, especially the modification of apolipoprotein B-100, has been implicated to play an important role in the pathogenesis of atherosclerosis. However, there have been few detailed insights into the chemical mechanism of derivatization of apolipoproteins during oxidation. In the present study, we provide evidence that the formation of the toxic pollutant acrolein (CH2=CH-CHO) and its conjugate with lysine residues is involved in the oxidative modification of human low density lipoprotein (LDL). Upon incubation with LDL, acrolein preferentially reacted with lysine residues. To determine the structure of acrolein-lysine adduct in protein, the reaction of acrolein with a lysine derivative was carried out. Employing Nalpha-acetyllysine, we detected a single product, which was identified to be a novel acrolein-lysine adduct, Nalpha-acetyl-Nepsilon-(3-formyl-3,4-dehydropiperidino )lysine. The acid hydrolysis of the adduct led to the derivative that was detectable with amino acid analysis. It was revealed that, upon in vitro incubation of LDL with acrolein, the lysine residues that had disappeared were partially recovered by Nepsilon-(3-formyl-3, 4-dehydropiperidino)lysine. In addition, we found that the same derivative was detected in the oxidatively modified LDL with Cu2+ and that the adduct formation was correlated with LDL peroxidation assessed by the consumption of alpha-tocopherol and cholesteryl ester and the concomitant formation of cholesteryl ester hydroperoxide. Enzyme-linked immunosorbent assay that measures free acrolein revealed that a considerable amount of acrolein was released from the Cu2+-oxidized LDL. Furthermore, metal-catalyzed oxidation of arachidonate was associated with the formation of acrolein, indicating that polyunsaturated fatty acids including arachidonate represent potential sources of acrolein generated during the peroxidation of LDL. These results indicate that acrolein is not just a pollutant but also a lipid peroxidation product that could be ubiquitously generated in biological systems.

Abstract
Acrolein is a highly toxic, reactive, and irritating aldehyde that occurs as a product of organic pyrolysis, as a metabolite of a number of compounds, and as a residue in water when used for the control of aquatic organisms. It is an intermediate in the production of acrylic acid, DL-methionine, and numerous other agents. Its major direct use is as a biocide for the control of aquatic flora and fauna. It is introduced to the environment from a variety of sources, including organic combustion such as automobile exhaust, cigarette smoke, and manufacturing and cooking emissions, as well as direct biocidal applications. Organic combustion from both fixed and mobile sources is the significant source of acrolein in the atmosphere; it represents up to 8% of the total aldehydes generated from vehicles and residential fireplaces and 13% of total atmospheric aldehydes. This reactive aldehyde also occurs in organisms as a metabolite of allyl alcohol, allylamine, spermine, spermidine, and the anticancer drug cyclophosphamide, and as a product of UV radiation of the skin lipid triolein. Furthermore, small amounts are found in foods; when animal or vegetable fats are overheated, however, large amounts are produced. Most human contact occurs during exposure to smoke from cigarettes, automobiles, industrial processes, and structural and vegetation fires. Besides cigarette smoke, occupational exposures are a common mode of human contact, particularly in industries that involve combustion of organic compounds. Firefighters, in particular, are exposed to extremely high levels during the extinguishment and overhaul phases of their work. Water may contain significant levels of the herbicide. It has been found in paper mill and municipal effluents at 20-200 micrograms/L, and at 30 micrograms/L as far as 64 km downstream from the point of application. The USEPA-recommended water quality criteria for freshwater are only 1.2 micrograms/L (24-hr avg) and 2.7 micrograms/L (maximum ceiling). Acrolein is highly reactive, and intercompartmental transport is limited. However, it is eliminated from aqueous environments by volatilization and hydration to beta-hydroxypropanal, after which biotransformation occurs, with a half-life of 7-10 d. The Koc for acrolein is 24, and it is not likely to be retained in soil; activated carbon adsorbs only 30% from solution. Thus, the aldehyde is either leached extensively in moist soil or volatilizes quickly from dry soil. It is eliminated from air by reaction with .OH (half-life, 0.5-1.2 d), NOx (half-life, 16 d), and O3 (half-life, 59 d), as well as by photolysis and wet deposition. As expected from its high water solubility, bioaccumulation is low. Acrolein is highly toxic by all routes of exposure. The respiratory system is the most common target: exposure causes localized irritation, respiratory distress, pulmonary edema, cellular necrosis, and increased susceptibility to microbial diseases. Additionally, acute inhalation studies verify that it is a severe respiratory irritant that affects respiratory rates. Respiratory rate depression may have a protective effect by minimizing vapor inhalation, thereby explaining the subadditive effect of acrolein when combined with the other toxic combustion by-products CO and HCHO. Liquid contact with the skin and eyes causes severe irritation, opaque or cloudy corneas, and localized epidermal necrosis, but no allergic contact dermatitis. The cardiovascular system is affected, resulting in increased blood pressure, platelet aggregation, and quick cessation of beating in perfused rat hearts. It may also inhibit mitochondrial oxidative phosphorylation in the myocardium. Acute LD50s and LC50s are low. Levels are 7-46 mg/kg and 18-750 mg/m3, respectively, in rats; aquatic organisms are affected above 11.4 micrograms/L.(ABSTRACT TRUNCATED)

Abstract
The influence of mus201 and mus308 mutants on acrolein mutagenicity was analyzed with the Drosophila melanogaster sex-linked recessive lethal test (SLRL), using the maternal approach, to further study the mechanisms of action of this chemical. The hypermutability indices obtained were 2.59 for mus201 and 0.52 for mus308 conditions. Statistical analysis indicates that whereas part of the acrolein-induced lesions are repaired by excision mechanism, as expected for a cyclic agent, there is no demonstrable influence of the mus308 locus on the mutagenicity of this chemical.

Abstract
Protein adducts are used as markers of chemical exposure. Determination of the clearance rate of these adducts from the blood circulation will provide the time frame for their measurement. Radioactive albumin was prepared biosynthetically by repeated intraperitoneal injections of L-[4,5-3H]lysine to a rat. After an affinity purification, an aliquot of this native [3H-lysine]albumin was adducted with 5 mM acrolein. Both the native albumin (A-treated group) and the albumin-acrolein adduct (AAA-treated group) were intravenously injected to separate groups of rats, and the clearance of radioactivity from the plasma was measured as a function of time. At the end of the experiment (33 h after the injection), radioactivity in the whole plasma, and in homogenates of liver, kidney and spleen and their trichloroacetic acid(TCA)-soluble and -insoluble fractions in both A- and AAA-treated groups, was measured. The results, at the initial 11 h after the injection, showed that the radioactivity was cleared from the circulating plasma more rapidly in the AAA-treated group (32% of the injected radioactivity remained) than the A-treated group (52%). At 33 h after the injection, 22% of the injected radioactivity remained in the plasma in the AAA-treated group as compared to 32% in the A-treated group. The whole homogenates of liver and kidney and their corresponding TCA-soluble fractions showed higher radioactivity in the AAA-treated group as compared to the A-treated group. However, the TCA-insoluble fractions from livers and kidneys of the AAA-treated group showed lower radioactivity as compared to the A-treated group. These results indicated that the albumin-acrolein adduct was removed more rapidly from the circulation than the native albumin, and degraded more rapidly by the liver and kidney. There was no preferential removal or degradation of the adducted albumin by the spleen.

Abstract
1. Trypanosoma brucei brucei-infected mouse models treated with a new antibiotic, reuterin, showed reduction of the levels of parasitemia and prolonged survival of the mice. 2. Cures of the parasitemia were observed in groups of mice treated with combinations of reuterin and suramin or melarsoprol. 3. Reuterin administered in combination with bleomycin or DL-alpha-difluoromethylornithine showed temporary remission of the parasitemia in groups of mice.

Abstract
Previous metabolic studies in rats have suggested in vivo formation of the acrolein-glutathione (acrolein-GSH) adduct following administration of the highly reactive alpha, beta-unsaturated aldehyde acrolein. Early studies by several investigators demonstrated that similar compounds such as alpha, beta-unsaturated aldehyde-cysteine adducts have toxic (carcinostatic) activity against Ehrlich ascites tumor cells implanted in mice. The current studies investigated the in vivo toxicity associated with the acrolein-GSH adduct in the male Sprague-Dawley rat. The 1:1 acrolein-GSH adduct was synthesized and characterized by physical-chemical methods. Rats given the acrolein-GSH adduct intravenously at 0.5 or 1 mmol/kg developed nephrotoxicity characterized by glucosuria, proteinuria, elevation in serum urea nitrogen, and gross and histologic changes of the kidney. The toxicity was not affected by pretreatment of rats with pyrazole, an alcohol dehydrogenase inhibitor; disulfiram, an inhibitor of aldehyde dehydrogenases; or probenecid, a renal organic anion transport inhibitor. Administration of a similar but nonaldehydic glutathione conjugate, S-n-propylglutathione, did not result in nephrotoxicity in the rat. The nephrotoxicity induced by the acrolein-GSH adduct was inhibited by acivicin, a gamma-glutamyl-transpeptidase inhibitor. These results indicate that the acrolein-GSH adduct requires processing through the first step of the renal mercapturic acid synthesis pathway to be activated to a toxic species.

Abstract
Forty-eight dogs were separated into four groups of six males and six females. Acrolein (0.1% aqueous) was administered in gelatin capsules to three of these groups at dosing levels of 0.1, 0.5 and 1.5 mg kg-1 day-1 based on results of a range-finding study. After 4 weeks, the high dose was increased to 2 mg kg-1 day-1. The fourth group received deionized water in the same number of gelatin capsules as the high-dose group. Dosing was 7 days per week for 53 weeks. Blood and biochemical measurements were made pretest and at 3-month intervals thereafter. At termination, all dogs were subjected to full necropsy and histological examination. The major test effect noted was frequent vomiting after dosing. This was observed to be dose-dependent and the frequency decreased with time, indicating an adaptive effect. One mid-dose female died during the test and was diagnosed as having died of severe bronchial pneumonia, probably a result of vomitus aspiration. Serum albumin, calcium and total protein values were depressed in high-dose animals throughout the study. Some variability in red blood cell parameters and coagulation times were noted but the significance of these effects was not obvious.
