Abstract
Metabolic reprogramming is a hallmark of cancer and the link between oncogenes activation, tumor supressors inactivation and bioenergetics modulation is well established. However, numerous carcinogenic environmental factors are responsible for early cancer initiation and their impact on metabolic reprogramming just starts to be deciphered. For instance, it was recently shown that UVB irradiation triggers metabolic reprogramming at the pre-cancer stage with implication for skin cancer detection and therapy. These observations foster the need to study the early changes in tissue metabolism following exposure to other carcinogenic events. According to the International Agency for Research on Cancer (IARC), tobacco smoke is a major class I-carcinogenic environmental factor that contains different carcinogens, but little is known on the impact of tobacco smoke on tissue metabolism and its participation to cancer initiation. In particular, tobacco-specific nitrosamines (TSNAs) play a central role in tobacco-smoke mediated cancer initiation. Here we describe the recent advances that have led to a new hypothesis regarding the link between nitrosamines signaling and metabolic reprogramming in cancer.

Effects of tobacco abuse on major chromosomal instability in human papilloma virus 16-positive oropharyngeal squamous cell carcinoma. Int J Oncol 2019; 55:527-535. [PMID: 31268157 DOI: 10.3892/ijo.2019.4826] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/12/2019] [Accepted: 05/31/2019] [Indexed: 11/05/2022] Open
Abstract
A substantial number of patients with oropharyngeal squamous cell carcinoma (OPSCC) have two oncogenic risk factors: Human papilloma virus (HPV) infection and tobacco use. These factors can be competitive or synergistic at the chromosomal and genomic levels, with strong prognostic and therapeutic implications. HPV16 has been shown in vitro to be a high‑risk HPV that induces low rates of chromosomal copy number alterations. However, chromosomal instability can be increased by smoking. Evaluating chromosomal instability in HPV‑positive patients according to their smoking status is therefore critical for assessing the prognosis and therapeutic impact. The aim of this study was to assess chromosomal instability in patients with HPV‑positive OPSCC according to smoking status. Chromosomal instability was investigated with array‑based comparative genomic hybridization (aCGH) in 50 patients with OPSCC. Differences in chromosomal alterations were examined according to the HPV and smoking status of the patients. HPV‑positive tumors (24/26 were HPV16‑positive) had fewer genomic aberrations (P=0.0082) and fewer breakpoints (P=0.048) than HPV‑negative tumors. We confirmed the association between HPV‑positive OPSCC and chromosomal losses at 11q. We verified the association between HPV‑negative OPSCC and losses at 3p and 9p and gains at 7q and 11q13. In the patients with OPSCC who were HPV‑positive, the total number of chromosomal aberrations per tumor was significantly higher in the group of patients who were smokers (P=0.003). However, the cytobands did not differ significantly according to the smoking status. On the whole, the data of this study may help to improve the stratification of HPV‑positive OPSCC patients and must be supplemented by next‑generation sequencing studies in order to describe the mutational and transcriptomic profiles of such patients according to smoking status.

Abstract
The tobacco-specific nitrosamine 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone (NNK) is the most potent risk factor among tobacco-related carcinogens in lung cancer progression and outcomes. Although genetic mutations and chromosome instability have been detected in NNK-induced lung tumors, the oncogenic mechanisms of NNK are not fully understood. Here, we show that NNK increases chromosomal instability by disrupting spindle microtubule (MT) attachment to the kinetochore (KT) and spindle dynamics. Mechanistically, NNK blocks the targeting of p53 to the centrosome during mitosis, leading to chromosome alignment defects in metaphase. Therefore, lung cancer cells with wild-type p53, such as A594 and H226B, are more resistant to the NNK treatment than p53-mutant lung cancer cells, such as A1299 and H226Br. Although NNK does not affect the levels or transcriptional activity of p53, the reduction of the p53 level at the centrosome exacerbates the NNK-induced chromosome alignment defect in A549 and H226B cells. Therefore, p53 protects against NNK-induced chromosome instability by modulating the function of centrosome-localized p53 and not by modulating transcriptional activity. We conclude that NNK may increase the risk of lung cancer progression and poorer outcomes in patients with p53 mutations by perturbing proper mitotic progression and chromosome integrity.

Abstract
Tobacco usage is a major risk factor in the development, progression, and outcomes for lung cancer. Of the carcinogens associated with lung cancer, tobacco-specific nitrosamines 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone (NNK) is among the most potent ones. The oncogenic mechanisms of NNK are not entirely understood, hindering the development of effective strategies for preventing and treating smoking-associated lung cancers. Here, we introduce the NNK-induced lung cancer animal models in different species and its potential mechanisms. Finally, we summarize several chemopreventive agents developed from these animal models.

NNK, a tobacco-specific carcinogen, inhibits the expression of lysyl oxidase, a tumor suppressor. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2014; 12:64-82.

Abstract
A tobacco-specific carcinogen, 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone (NNK), is believed to contribute to the cancer burden in cigarette smokers. To evaluate NNK effects on the expression of lysyl oxidase (LOX), a tumor suppressor, we examined this enzyme at various levels in NNK-treated rat fetal lung fibroblasts (RFL6). Exposure of cells to NNK reduced levels of steady-states LOX mRNA and new transcript synthesis. NNK inhibited all LOX protein species in a dose-dependent manner. Although 300 µM NNK markedly decreased the level in the 46 kDa preproenzyme, under same conditions, there was no detectable amounts of the 50 kDa proenzyme and the 32 kDa mature enzyme suggesting NNK perturbing the LOX protein processing to its mature form. Moreover, NNK also suppressed LOX activities in conditioned media of treated cells. At the promoter level, NNK enhanced methylation of CpG, but decreased acetylation of histone H3 at the core promoter region of the LOX gene. These results indicated that transcriptional and translational processes of LOX are major targets for NNK. Thus, inactivation of tumor suppressor gene LOX may play a critical role in NNK carcinogenesis.

Abstract
IGFBP-3 is a tumor suppressor whose expression is frequently suppressed in lung cancer. NNK, the most potent tobacco carcinogen, enhanced cell proliferation of BEAS-2B normal lung epithelial cells and concomitantly suppressed IGFBP-3 expression through DNA methylation. Decreased IGFBP-3 expression and elevated levels of phospho-Akt, phospho-p65-NF-κB, and cyclin D1 were detected in tobacco carcinogen-induced tumorigenic derivatives of BEAS-2B. Overexpression of IGFBP-3 in NNKA, one of the derivatives, suppressed NF-κB activity and induced apoptosis, which was hindered by knocking-down of endogenous IGFBP-3R, an IGFBP-3 specific receptor. These results suggest that NNK inhibits IGFBP-3 expression to abrogate anti-tumor actions of the IGFBP-3/IGFBP-3R system in smoking-induced lung cancer.

Abstract
In the past two decades comparative genomic hybridization (CGH) and array CGH have become crucial and indispensable tools in clinical diagnostics. Initially developed for the genome-wide screening of chromosomal imbalances in tumor cells, CGH as well as array CGH have also been employed in genotoxicology and most recently in toxicogenomics. The latter methodology allows a multi-endpoint analysis of how genes and proteins react to toxic agents revealing molecular mechanisms of toxicology. This chapter provides a background on the use of CGH and array CGH in the context of genotoxicology as well as a protocol for conventional CGH to understand the basic principles of CGH. Array CGH is still cost intensive and requires suitable analytical algorithms but might become the dominating assay in the future when more companies provide a large variety of different commercial DNA arrays/chips leading to lower costs for array CGH equipment as well as consumables such as DNA chips. As the amount of data generated with microarrays exponentially grows, the demand for powerful adaptive algorithms for analysis, competent databases, as well as a sound regulatory framework will also increase. Nevertheless, chromosomal and array CGH are being demonstrated to be effective tools for investigating copy number changes/variations in the whole genome, DNA expression patterns, as well as loss of heterozygosity after a genotoxic impact. This will lead to new insights into affected genes and the underlying structures of regulatory and signaling pathways in genotoxicology and could conclusively identify yet unknown harmful toxicants.

Abstract
The nitrosamine 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone (NNK), an important carcinogen found in tobacco products, causes lung cancer in genetically susceptible animals. In addition to mutations of the K-Ras gene, NNK has non-mutagenic effects that include alterations in gene expression and immunomodulation in the lung. Here we report the identification of two gene sets associated with NNK-induced pulmonary tumourigenesis. First, to identify genes involved in the susceptibility to NNK, we compared the lung transcriptomes of NNK-resistant C3H mice with that of the NNK-susceptible A/J mice, identifying differential expression of genes related to innate immunity and inflammation. Second, to identify gene expression induced by NNK, we compared the lung transcriptomes of C3H and A/J mice post-treatment. The Resistin-like alpha (Retnla) gene was highly upregulated in response to NNK only in susceptible mice. This gene product is known to recruit immune cells to the lung, and accumulation of CD45 positive cells in A/J lungs correlated with increased Retnla expression. Genetic susceptibility to NNK-induced lung tumourigenesis may relate in part to gene expression changes and alterations in the immune response to create a pro-tumourigenic environment, acting in concert with NNK's mutagenic effects.

Abstract
Iron overload has been associated with carcinogenesis in humans. Intraperitoneal administration of ferric nitrilotriacetate initiates a Fenton reaction in renal proximal tubules of rodents that ultimately leads to a high incidence of renal cell carcinoma (RCC) after repeated treatments. We performed high-resolution microarray comparative genomic hybridization to identify characteristics in the genomic profiles of this oxidative stress-induced rat RCCs. The results revealed extensive large-scale genomic alterations with a preference for deletions. Deletions and amplifications were numerous and sometimes fragmented, demonstrating that a Fenton reaction is a cause of such genomic alterations in vivo. Frequency plotting indicated that two of the most commonly altered loci corresponded to a Cdkn2a/2b deletion and a Met amplification. Tumor sizes were proportionally associated with Met expression and/or amplification, and clustering analysis confirmed our results. Furthermore, we developed a procedure to compare whole genomic patterns of the copy number alterations among different species based on chromosomal syntenic relationship. Patterns of the rat RCCs showed the strongest similarity to the human RCCs among five types of human cancers, followed by human malignant mesothelioma, an iron overload-associated cancer. Therefore, an iron-dependent Fenton chemical reaction causes large-scale genomic alterations during carcinogenesis, which may result in distinct genomic profiles. Based on the characteristics of extensive genome alterations in human cancer, our results suggest that this chemical reaction may play a major role during human carcinogenesis.

Abstract
Betel Quid (BQ) chewing independently contributes to oral, hepatic and esophageal carcinomas. Strong association of breast cancer risk with BQ chewing in Northeast Indian population has been reported where this habit is prodigal. We investigated genomic alterations in breast cancer patients with and without BQ chewing exposure. Twenty six BQ chewers (BQC) and 17 non BQ chewer (NBQC) breast cancer patients from Northeast India were analyzed for genomic alterations and pathway networks using SNP array and IPA. BQC tumors showed significantly (P<0.01) higher total number of alterations, as compared with NBQC tumors, 48±17% versus 32±25 respectively. Incidence of gain in fragile sites in BQC tumors were significantly (P<0.001) higher as compared with NBQC tumors, 34 versus 23% respectively. Two chromosomal regions (7q33 and 21q22.13) were significantly (p<0.05) associated with BQC tumors while two regions (19p13.3–19p12 and 20q11.22) were significantly associated with NBQC tumors. GO terms oxidoreductase and aldo-keto reductase activity in BQC tumors in contrast to G-protein coupled receptor protein signaling pathway and cell surface receptor linked signal transduction in NBQC tumors were enriched in DAVID. One network “Drug Metabolism, Molecular Transport, Nucleic Acid Metabolism” including genes AKR1B1, AKR1B10, ETS2 etc in BQC and two networks “Molecular Transport, Nucleic Acid Metabolism, Small Molecule Biochemistry” and “Cellular Development, Embryonic Development, Organismal Development” including genes RPN2, EMR3, VAV1, NNAT and MUC16 etc were seen in NBQC. Common alterations (>30%) were seen in 27 regions. Three networks were significant in common regions with key roles of PTK2, RPN2, EMR3, VAV1, NNAT, MUC16, MYC and YWHAZ genes. These data show that breast cancer arising by environmental carcinogens exemplifies genetic alterations differing from those observed in the non exposed ones. A number of genetic changes are shared in both tumor groups considered as crucial in breast cancer progression.

Abstract
The incidence of lung adenocarcinoma has been remarkably increasing in recent years due to the introduction of filter cigarettes and secondary-hand smoking because the people are more exposed to higher amounts of nitrogen oxides, especially 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone(NNK), which is widely applied in animal model of lung tumors. In NNK-induced lung tumors, genetic mutation, chromosome instability, gene methylation, and activation of oncogenes have been found so as to disrupt the expression profiles of some proteins or enzymes in various cellular signal pathways. Transgenic animal with specific alteration of lung cancer-related molecules have also been introduced to clarify the molecular mechanisms of NNK in the pathogenesis and development of lung tumors. Based on these animal models, many antioxidant ingredients and antitumor chemotherapeutic agents have been proved to suppress the NNK-induced lung carcinogenesis. In the future, it is necessary to delineate the most potent biomarkers of NNK-induced lung tumorigenesis, and to develop efficient methods to fight against NNK-associated lung cancer using animal models.

Abstract
Tobacco smoke consists of numerous carcinogens whose effect on lung tumor development includes the induction of mutations in key genes as well as the induction of chromosome instability (CIN). Consequently, carcinogen-induced mouse lung adenocarcinomas (LAC) display many more recurrent site- and chromosome-specific changes in DNA copy number compared with noninduced LAC. Here we identified the Adenylosuccinate synthetase 1 (Adss1) gene located on distal chromosome 12q as a focus of bi-allelic or homozygous deletion (HD) in LAC. HDs of Adss1 were detected in 10 out of 84 carcinogen-induced mouse primary LAC and mouse LAC cell lines. In only four of these cases did the deletions affect either Siva1 or Inverted-formin 2 (Inf2), which immediately flank the Adss1 locus, indicating that Adss1 is a selective target of deletion in LAC. Losses of Adss1 not meeting the quantitative threshold of HD were detected in 36 out of 84 (42.9%) of the mouse tumors and cell lines. A similar frequency of ADSS1 deletion was observed in human LAC cell lines, suggesting relevance in human lung cancer. Adss1 losses were also found to be significantly associated with a more extensive CIN phenotype in the primary mouse tumors. These results implicate ADSS1 inactivation as a novel somatic alteration in lung carcinogenesis, and suggest that its selective deletion in LAC may be triggered by CIN.

Abstract
Cigarette smoking has been investigated as a major risk factor for renal cell carcinoma (RCC). 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone (NNK) is one of the most abundant carcinogenic N-nitrosamines present in cigarette smoke. However, the association between repair capacity of NNK-induced DNA damage and RCC risk remains unknown. We used the comet assay to assess whether sensitivity to a NNK precursor 4-[(acetoxymethyl) nitrosamino]-1-(3-pyridyl)-1-butanone (NNKOAc) induced DNA damage, which partly reflects host sensitivity to NNK, was associated with increased risk of RCC in a population-based case-control study. The study included 95 RCC cases and 188 matched controls. Epidemiologic data were collected via in-person interview. Baseline and NNK-induced DNA damage in peripheral blood lymphocytes were measured using the comet assay and quantified by the Olive tail moment. The NNKOAc-induced median Olive tail moments were significantly higher in cases than in controls (2.27 versus 1.76, P = 0.002). Using the 75th percentile Olive tail moments of the controls as the cutoff point, we found that higher levels of NNKOAc-induced DNA damage were associated with a significantly increased risk of RCC [odds ratio, 2.06; 95% confidence interval, 1.17-3.61]. In quartile analysis, there was a dose-response association between NNKOAc-induced damage and risk of RCC (P for trend, 0.006). Our data strongly suggest that higher levels of NNKOAc-induced damage are associated with higher risks of RCC. Future studies with larger sample sizes are warranted to further investigate whether repair of NNKOAc-induced damage, as quantified by the comet assay, could be used as a predictive marker for RCC risk.
