Abstract
Under acidic and high temperature conditions, 5-hydroxymethylfurfural (5-HMF) converted from sugar further produces dimers (Compound II) and trimers (Compound III). The polymers were less reported, and sensitization effect of them was reported in this study. Compounds II and III induced the local and systemic anaphylaxis effect in passive cutaneous anaphylaxis mice model and activated RBL-2H3 cell inducing [Ca2+ ] mobilization, resulting in the release of β-hexosaminidase and histamine in vitro. The gene knockdown assay figured out that Compounds II and III induced degranulation through FcεRI. Further, Compounds II and III had a certain affinity with FcεRI by cell membrane chromatography and may combine on the "proline sandwich" structure indicated by molecular docking. All above suggested Compounds II and III can induce pseudo-allergic reaction through FcεRI in vivo and in vitro. Our work provides basic research to prove that the newly discovered 5-HMF transformants, Compounds II and III, induce pseudo-allergic reaction in vitro and in vivo through FcεRI, which is different pathway from 5-HMF. In foods with high sugar content, the sensitization of Compounds II and III needs more attention. In high-sugar foods and medicines, especially traditional Chinese medicine injections, the content of transformants needs to be detected.

Abstract
Sulfotransferase Family 1A Member 2 (SULT1A2) is a protein coding gene. Several studies have reported that SULT1A2 may have a chemical carcinogenic effect if expressed as a functional protein. The present study aimed to investigate the expression and potential role of SULT1A2 in bladder cancer (BC). Data from The Cancer Genome Atlas (TCGA) and Gene Expression Omnibus databases were used to analyze SULT1A2 expression in BC. In addition, reverse transcription-quantitative PCR and western blot analyses were performed to detect SULT1A2 expression in BC cells and tissues. Immunohistochemistry analysis was performed on 100 formalin-fixed, paraffin-embedded BC tissues and corresponding adjacent normal bladder tissues (ANBTs) to verify SULT1A2 expression and determine the clinical significance of SULT1A2 in BC. Gene set enrichment analysis (GSEA) was performed to determine the potential biological processes and internal molecular mechanisms. The results demonstrated that SULT1A2 was highly expressed in BC tissues compared with ANBTs. Furthermore, high SULT1A2 expression was significantly associated with the staging of BC. Analyses of TCGA datasets and BC tissue microarray indicated that high SULT1A2 expression was significantly associated with a favorable overall survival in patients with BC. In addition, GSEA revealed pathways, diseases and biological processes associated with SULT1A2. Taken together, the results of the present study suggest that SULT1A2 acts as an oncogene in BC, and thus may serve as a biomarker for tumor staging and prognosis in patients with BC.

Abstract
Nicotiana tabacum, Stemona japonica, and Cnidium monnieri are common plants that are widely used for their anti-parasitic properties. The purpose of this study was to evaluate the acaricidal activity of extracts from these plants against the brown dog tick, Rhipicephalus sanguineus. A composition analysis of crude extracts by GC-MS was conducted to discover compounds with acaricidal effects. The toxicity of extraction against the engorged nymphs of R. sanguineus was evaluated by an immersion test. The results showed that the crude extracts of S. japonica and C. monnieri in varying ratios, concentrations, and from different extraction methods, had a killing effect on R. sanguineus. Lethality reached 76.67% ± 0.04410 when using a 1:1 extract of S. japonica:C. monnieri in 75% ethanol with ultrasonic extraction; the crude extract was determined at a concentration of 0.5 g/mL. GC-MS results showed that osthole and 5-hydroxymethylfurfural (5-HMF) are the main components of the extract. These results suggested that ultrasound-assisted extraction (UAE) extracts contained acaricidal components acting against R. sanguineus, which may result in the development of effective extracts of S. japonica and C. monnieri as a source of low-toxicity, plant-based, natural acaricidal drugs.

Abstract
5-Hydroxymethylfurfural (5-HMF) is present in numerous carbohydrate-containing consumer products and is readily converted into two oligomers (II and III) by acid-catalyzed transformations. Previous studies have demonstrated various undesirable effects of 5-HMF at relatively high concentrations. In this study, we demonstrate that 5-HMF and its two oligomers exert neurotoxic effects in vivo and in vitro. All three substances blocked the proliferation of PC12 and HT22 cells at the S or G2-M phase in dose- and time-dependent manners. In addition, [Ca2+]i and reactive oxygen species levels were both significantly increased by treatment with these substances at 100 μM, individually, compared with the control group. Although no motor and cognitive deficits are observed, 5-HMF and III can induce anxiety- and depression-like behavior in adolescent mice at administered doses of 0.15 mg kg-1 and 1.5 mg kg-1in vivo, which are close to or less than the reported 24 h dietary intake of 5-HMF in humans. Together, our findings suggest the need for close monitoring of the content of these substances in food, as well as the need for studies on the effects of long-term exposure to them.

Abstract
Red meat is probably carcinogenic to humans (WHO/IARC class 2A), in part through heme iron-induced lipoperoxidation. Here, we investigated whether red meat promotes carcinogenesis in rodents and modulates associated biomarkers in volunteers, speculating that an antioxidant marinade could suppress these effects via limitation of the heme induced lipid peroxidation. We gave marinated or non-marinated beef with various degrees of cooking to azoxymethane-initiated rats, Min mice, and human volunteers (crossover study). Mucin-depleted foci were scored in rats, adenoma in Min mice. Biomarkers of lipoperoxidation were measured in the feces and urine of rats, mice, and volunteers. The organoleptic properties of marinated meat were tested. Fresh beef increased colon carcinogenesis and lipoperoxidation in rats and mice and lipoperoxidation in humans. Without an adverse organoleptic effect on meat, marinade normalized peroxidation biomarkers in rat and mouse feces, reduced peroxidation in human feces and reduced the number of Mucin-depleted foci in rats and adenoma in female Min mice. This could lead to protective strategies to decrease the colorectal cancer burden associated with red meat consumption. Cancer Prev Res; 11(9); 569-80. ©2018 AACR.

Abstract
The small molecule anticancer agent NSC-743380 modulates functions of multiple cancer-related pathways and is highly active in a subset of cancer cell lines in the NCI-60 cell line panel. It also has promising in vivo anticancer activity. However, the mechanisms underlying NSC-743380's selective anticancer activity remain uncharacterized. To determine biomarkers that may be used to identify responders to this novel anticancer agent, we performed correlation analysis on NSC-743380's anticancer activity and the gene expression levels in NCI-60 cell lines and characterized the functions of the top associated genes in NSC-743380–mediated anticancer activity. We found sulfotransferase SULT1A1 is causally associated with NSC-743380's anticancer activity. SULT1A1 was expressed in NSC-743380–sensitive cell lines but was undetectable in resistant cancer cells. Ectopic expression of SULT1A1 in NSC743380 resistant cancer cells dramatically sensitized the resistant cells to NSC-743380. Knockdown of the SULT1A1 in the NSC-743380 sensitive cancer cell line rendered it resistance to NSC-743380. The SULT1A1 protein levels in cell lysates from 18 leukemia cell lines reliably predicted the susceptibility of the cell lines to NSC-743380. Thus, expression of SULT1A1 in cancer cells is required for NSC-743380's anticancer activity and can be used as a biomarker for identification of NSC-743380 responders.

Abstract
Activating mutations of oncogenic RAS genes are frequently detected in human cancers. The studies in genetically engineered mouse models (GEMMs) reveal that Kras-activating mutations predispose mice to early onset tumors in the lung, pancreas, and gastrointestinal tract. Nevertheless, most of these tumors do not have metastatic phenotypes. Metastasis occurs when tumors acquire additional genetic changes in other cancer driver genes. Studies on clinical specimens also demonstrated that KRAS mutations are present in premalignant tissues and that most of KRAS mutant human cancers have co-mutations in other cancer driver genes, including TP53, STK11, CDKN2A, and KMT2C in lung cancer; APC, TP53, and PIK3CA in colon cancer; and TP53, CDKN2A, SMAD4, and MED12 in pancreatic cancer. Extensive efforts have been devoted to develop therapeutic agents that target enzymes involved in RAS posttranslational modifications, that inhibit downstream effectors of RAS signaling pathways, and that kill RAS mutant cancer cells through synthetic lethality. Recent clinical studies have revealed that sorafenib, a pan-RAF and VEGFR inhibitor, has impressive benefits for KRAS mutant lung cancer patients. Combination therapy of MEK inhibitors with either docetaxel, AKT inhibitors, or PI3K inhibitors also led to improved clinical responses in some KRAS mutant cancer patients. This review discusses knowledge gained from GEMMs, human cancer cells, and patient-related studies on RAS-mediated tumorigenesis and anti-RAS therapy. Emerging evidence demonstrates that RAS mutant cancers are heterogeneous because of the presence of different mutant alleles and/or co-mutations in other cancer driver genes. Effective subclassifications of RAS mutant cancers may be necessary to improve patients' outcomes through personalized precision medicine.

Abstract
The food processing contaminants 2-amino-1-methyl-6-phenylimidazo[4,5-b]pyridine (PhIP), 5-hydroxymethylfurfural (HMF) and 2,5 dimethylfuran (DMF) are potentially both mutagenic and carcinogenic in vitro and/or in vivo, although data on DMF is lacking. The PHIP metabolite N-hydroxy-PhIP and HMF are bioactivated by sulfotransferases (SULTs). The substrate specificity and tissue distribution of SULTs differs between species. A single oral dose of PhIP, HMF or DMF was administered to wild-type (wt) mice and mice expressing human SULT1A1/1A2 (hSULT mice). DNA damage was studied using the in vivo alkaline single cell gel electrophoresis (SCGE) assay. No effects were detected in wt mice. In the hSULT mice, PhIP and HMF exposure increased the levels of DNA damage in the liver and kidney, respectively. DMF was not found to be genotoxic. The observation of increased DNA damage in hSULT mice compared with wt mice supports the role of human SULTs in the bioactivation of N-hydroxy-PhIP and HMF in vivo.

Abstract
The molecular characterization of various cancers has shown that cancers with the same origins, histopathologic diagnoses, and clinical stages can be highly heterogeneous in their genetic and epigenetic alterations that cause tumorigenesis. A number of cancer driver genes with functional abnormalities that trigger malignant transformation and that are required for the survival of cancer cells have been identified. Therapeutic agents targeting some of these cancer drivers have been successfully developed, resulting in substantial improvements in clinical symptom amelioration and outcomes in a subset of cancer patients. However, because such therapeutic drugs often benefit only a limited number of patients, the successes of clinical development and applications rely on the ability to identify those patients who are sensitive to the targeted therapies. Thus, biomarkers that can predict treatment responses are critical for the success of precision therapy for cancer patients and of anticancer drug development. This review discusses the molecular heterogeneity of lung cancer pathogenesis; predictive biomarkers for precision medicine in lung cancer therapy with drugs targeting epidermal growth factor receptor (EGFR), anaplastic lymphoma kinase (ALK), c-ros oncogene 1 receptor tyrosine kinase (ROS1), and immune checkpoints; biomarkers associated with resistance to these therapeutics; and approaches to identify predictive biomarkers in anticancer drug development. The identification of predictive biomarkers during anticancer drug development is expected to greatly facilitate such development because it will increase the chance of success or reduce the attrition rate. Additionally, such identification will accelerate the drug approval process by providing effective patient stratification strategies in clinical trials to reduce the sample size required to demonstrate clinical benefits.

Abstract
Considerable support exists for the roles of metabolism in modulating the carcinogenic properties of chemicals. In particular, many of these compounds are pro-carcinogens that require activation to electrophilic forms to exert genotoxic effects. We systematically analyzed the existing literature on the metabolism of carcinogens by human enzymes, which has been developed largely in the past 25 years. The metabolism and especially bioactivation of carcinogens are dominated by cytochrome P450 enzymes (66% of bioactivations). Within this group, six P450s--1A1, 1A2, 1B1, 2A6, 2E1, and 3A4--accounted for 77% of the P450 activation reactions. The roles of these P450s can be compared with those estimated for drug metabolism and should be considered in issues involving enzyme induction, chemoprevention, molecular epidemiology, interindividual variations, and risk assessment.
