Abstract
As kinds of endocrine disruptors, organophosphate esters (OPEs) pollution in the environment had received increasing attention recently. Food and water intake were two important exposure pathways for OPEs. However, the studies about the potential association between OPEs and gastrointestinal cancer were limited. This study investigated the possible association between OPEs and gastrointestinal cancer. All cancer patients were diagnosed with gastrointestinal cancer from a Grade 3 A hospital in Wuhan, China, while the control group was non-cancer healthy persons. The results showed that 6 OPEs were found in the control samples, while 8 in the samples from patients with gastrointestinal cancer. The detection frequencies of OPEs in gastrointestinal cancer patients were significantly higher than those in the control group (p < 0.05 or p < 0.01), except for triethyl phosphate (TEP) and tris (methylphenyl) phosphate (TMPP) in the gastric cancer group. The concentrations of OPEs in the control group were significantly lower than those in the gastric cancer group and colorectal cancer group (p < 0.01). In the control group and gastrointestinal cancer group, TEP was the dominant pollutant. Correlation analysis found that concentrations of TEP, tris(2-chloroisopropyl) phosphate (TCIPP), triphenyl phosphate (TPHP), TMPP, tris(2-ethylhexyl) phosphate (TEHP), and 2-ethylhexyl diphenyl phosphate (EHDPP) were associated with gastric cancer (p < 0.01), and concentrations of TEP, TCIPP, TPHP, TMPP and TEHP were associated with colorectal cancer (p < 0.01). A cluster analysis divided the 34 patients with gastric cancer and 40 patients with colorectal cancer in four groups. The results showed that the elderly male patients with gastric cancer were more sensitive to the exposure of EHDPP, while the TEP exposure was more sensitive to the relatively young gastrointestinal cancer patients. These findings indicated that OPEs might play a role in developing gastrointestinal cancer.

New insights of CYP1A in endogenous metabolism: a focus on single nucleotide polymorphisms and diseases. Acta Pharm Sin B 2020; 10:91-104. [PMID: 31998606 PMCID: PMC6984740 DOI: 10.1016/j.apsb.2019.11.016] [Citation(s) in RCA: 49] [Impact Index Per Article: 12.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/04/2019] [Revised: 10/13/2019] [Accepted: 10/16/2019] [Indexed: 12/31/2022] Open
Abstract
Cytochrome P450 1A (CYP1A), one of the major CYP subfamily in humans, not only metabolizes xenobiotics including clinical drugs and pollutants in the environment, but also mediates the biotransformation of important endogenous substances. In particular, some single nucleotide polymorphisms (SNPs) for CYP1A genes may affect the metabolic ability of endogenous substances, leading to some physiological or pathological changes in humans. This review first summarizes the metabolism of endogenous substances by CYP1A, and then introduces the research progress of CYP1A SNPs, especially the research related to human diseases. Finally, the relationship between SNPs and diseases is discussed. In addition, potential animal models for CYP1A gene editing are summarized. In conclusion, CYP1A plays an important role in maintaining the health in the body.

Association between polymorphisms in the CYP1A1, CYP2E1 and GSTM1 genes, and smoking, alcohol and upper digestive tract carcinomas in a high-incidence area of northern China. Oncol Lett 2019; 18:1267-1277. [PMID: 31423187 PMCID: PMC6607096 DOI: 10.3892/ol.2019.10455] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/26/2018] [Accepted: 04/14/2019] [Indexed: 12/15/2022] Open
Abstract
Metabolic gene variants, smoking, and alcohol consumption are important upper digestive tract cancer (UDTC) risk factors. However, the gene-gene and gene-environment interactions remain unclear. A case-control study in a high incidence area for upper digestive tract cancer was conducted in China. DNA was extracted from buffy coat samples for PCR or PCR-restriction fragment length polymorphism. Smoking and alcohol drinking status was determined by questionnaires. Odds ratios (ORs) and 95% confidence intervals (CIs) were used to assess the associations. After adjusting for confounding factors, smoking increased esophageal cancer (EC), gastric cardia cancer (GCC) and gastric antral carcinoma (GAC) risk by 3.594, 4.658, and 3.999-fold, respectively. Alcohol consumption increased EC, GCC and GAC risk by 1.953, 2.442 and 1.765-fold, respectively. The cytochrome P4501A1 (CYP1A1) rs4646903 T>C polymorphism increased GCC risk, the cytochrome P4502E1 (CYP2E1) rs2031920 C>T polymorphism increased EC risk, while the GSTM1 null genotype decreased EC risk. An association existed between the following: CYP1A1 rs4646903 and smoking in EC, GCC and GAC; CYP1A1 rs4646903 and alcohol consumption in EC and GCC; CYP2E1 rs2031920 and smoking in EC, GCC and GAC and CYP2E1 rs2031920 and alcohol consumption in EC and GCC. No association was observed between CYP1A1 and CYP2E1. The glutathione S-transferase mu 1 (GSTM1) null genotype decreased EC risk (OR=0.510). Smoking/drinking are upper digestive tract cancer risk factors. The CYP1A1 rs4646903 and CYP2E1 rs2031920 polymorphisms were risk factors of GCC or EC, and the GSTM1 null genotype may serve a protective role against EC. The results of the present study indicated that gene-environment interactions increase the risk of UDTC.
