AIM:To evaluate the association between genetic polymorphisms in CYP2E1, ALDH2 and ADH1B and the risk of esophageal squamous cell carcinoma (ESCC) in a high risk area of Gansu Province, in Chinese males. METHODS: A case-control study was conducted to investigate the genetic polymorphisms of these enzymes (CYP2E1 *c1/*c2, ALDH2 *1/*2 and ADH1B *1/*1 genotypes). A total of 80 esophageal cancer cases and 480 controls were recruited. RESULTS: Compared with controls, cases had a greater prevalence of heavier alcohol consumption (53.8% vs 16.2%) and a higher proportion of alcohol drinkers with > 30 drink-years (28.8% vs 13.5%). Heavier alcohol consumption and alcohol drinking with > 30 drink- years increased the risk of ESCC, with ORs (95% CI) of 3.20 (1.32-9.65) and 1.68 (0.96-3.21). CYP2E1 (*c1/*c1), ALDH2 (*1/*2) and ADH1B (*1/*1) genotype frequencies were higher among patients with squamous cell carcinomas, at a level close to statistical significance (P = 0.014; P = 0.094; P = 0.0001 respectively). There were synergistic interactions among alcohol drinking and ALDH2, ADH1B and CYP2E1 genotypes. The risk of the ESCC in moderate-to-heavy drinkers with an inactive ALDH2 encoded by ALDH2 *1/*2 as well as ADH1B encoded by ADH1B *1/*1 and CYP2E1 encoded by CYP2E1 *c1/*c1 was higher than that in the never/rare-to-light drinkers with an active ALDH2 (*1/*1 genotype) as well as ADH1B (*1/*2 + *2/*2) and CYP2E1 (*c1/*c2 + *c2/*c2) genotypes, with a statistically significant difference; ORs (95% CI) of 8.58 (3.28-22.68), 27.12 (8.52-70.19) and 7.64 (2.82-11.31) respectively. The risk of the ESCC in moderate-to-heavy drinkers with ALDH2 (*1/*2) combined the ADH1B (*1/*1) genotype or ALDH2 (*1/*2) combined the CYP2E1 (*c1/*c1) genotype leads to synergistic interactions, higher than drinkers with ALDH2 (*1/*1) + ADH1B (*1/*2 + *2/*2), ALDH2 (*1/*1) + CYP2E1 (*c1/*c2 + *c2/*c2) respectively , ORs (95% CI) of 7.46 (3.28-18.32) and 6.82 (1.44-9.76) respectively.

Yanting 621600 SichuanProvince China

AIM＂ TO evaluate the impact of alcohol dehydrogenase 2 （ADH2） and aldehyde dehydrogenase 2 （ALDH2） polymorphisms on esophageal cancer risk. METHODS;One hundred and ninety-one esophageal cancer patients and 198 healthy controls from Yanting County were enrolled in this study. ADH2 and ALDH2 genotypes were examined by polymerase-chain-reaction with the confronting-two-pair-primer （PCR-CTPP） method. Unconditional logistic regression was used to calculate the odds ratios （OR） and 95% confidence interval （95% CI）. RESULTS; Both ADH2＊1 allele and ALDH2＊1/＊2 allele showed an increased risk of developing esophageal cancer. The adjusted OR （95% CI） for ADH2＊1 allele compared with ADH2＊2/＊2 was 1.65 （95% CI = 1.02-2.68） and 1.67 （95% CI = 1.02-2.72） for ALDH2＊1/＊2 compared with ALDH2＊1/＊1. A significant interaction between ALDH2 and drinking was detected regarding esophageal cancer risk, the OR was 1.83 （95% CI = 1.13-2.95）. Furthermore, when compared with ADH2＊2/＊2 and ALDH2＊1/＊1 carriers, ADH2＊1 and ALDH2＊2 carriers showed an elevated risk of developing esophageal cancer among non-alcohol drinkers

AIM: To investigate the association between single nucleotide polymorphisms (SNPs) in the phosphatase and tensin homolog (PTEN) tumor suppressor gene and risk of colon cancer. METHODS: We utilized a population-based casecontrol study of incident colon cancer individuals (n= 421) and controls (n = 483) aged ≥ 30 years to conduct a comprehensive tagSNP association analysis of the PTEN gene. RESULTS: None of the PTEN SNPs were statistically significantly associated with colon cancer when controlled for age, gender, and race, or when additionally adjusted for other known risk factors (P > 0.05). Haplotype analyses similarly showed no association between the PTEN gene and colon cancer. CONCLUSION: Our study does not support PTEN as a colon cancer susceptibility gene.

Imatinib mesylate(IM) has dramatically improved the outcomes of gastrointestinal stromal tumor(GIST) patients. However, the clinical responses of IM may considerably vary among single individuals. This study aimed to investigate the influences of genetic polymorphisms of drug-metabolizing enzyme(CYP3A4), transporters(ABCB1, ABCG2), and nuclear receptor(Pregnane X Receptor(PXR, encoded by NR1I2)) on IM plasma levels and related adverse reactions in Chinese GIST patients. A total of 68 Chinese GIST patients who have received IM 300–600 mg/day were genotyped for six single nucleotide polymorphisms(SNPs)(CYP3A4 rs2242480;ABCB1 rs1045642;ABCG2 rs2231137;NRI12 rs3814055, rs6785049, rs2276706), and the steady-state IM trough plasma concentrations were measured by a validated HPLC method. There were statistically significant variances in the steady-state IM trough plasma concentrations(from 272.22 to 4365.96 ng/m L). Subjects of GG in rs2242480, T allele carriers in rs1045642 and CC in rs3814055 had significantly higher steady-state IM dose-adjusted trough plasma concentrations. Subjects of CC in rs3814055 had significantly higher incidence rate of edema. The genetic polymorphisms of rs2242480, rs1045642, rs3814055 were significantly associated with IM plasma levels, and the genetic variations of rs3814055 were significantly associated with the incidence rate of edema in Chinese GIST patients. The current results may serve as valuable fundamental knowledge for IM therapy in Chinese GIST patients.

Mycophenolate mofetil（MMF） is an immunosuppressive drug used with organ transplant recipients. The active metabolite of MMF is mycophenolic acid（MPA）, which has considerable interpatient variability in its pharmacokinetics. genetic variants may be important in this variability. This study evaluated genetic variants affecting MPA metabolism in Chinese renal transplant recipients. A retrospective study of 408 Chinese renal transplant recipients receiving MMF as an immunosuppressive drug was conducted. Eleven single nucleotide polymorphisms（SNPs） of UGT1 A9, UGT1 A8, UGT2 B7, ABCC2, ABCG2, and SLCO1 B3 were genotyped with the high resolution melting assay. Associations between each SNP and MPA concentration/dose ratio（C0/D） were analyzed using different genetic models. Pearson correlation was used to analyze associations between C0/D and clinical factors. UGT2 B7 rs7662029 genotype was associated with MPA C0/D using a dominant（p = 0.024） and an additive model（p = 0.028）. ABCC2 rs717620 genotype was associated with C0/D using a recessive model（p = 0.043）. Using the additive model, SNP-SNP interactions were identified（p = 0.002） between ABCC2 rs717620 and UGT1 A9 rs2741049 with similar interactions（p = 0.002） between ABCC2 rs717620 and UGT1 A8 rs1042597. Age, weight, hematocrit, hemoglobin, albumin and direct bilirubin were significantly associated with MPA C0/D. UGT2 B7 rs7662029 and ABCC2 rs717620 might be SNPs that affect MPA pharmacokinetics in Chinese renal transplant recipients. SNP-SNP interactions and clinical factors may have significant effects on MPA metabolism.

AIM: To investigate roles of genetic polymorphisms in non-alcoholic fatty liver disease (NAFLD) onset, severity, and outcome through systematic literature ***: The authors conducted both systematic and specific searches of PubMed through December 2015 with special emphasis on more recent data (from 2012 onward) while still drawing from more historical data for background. We identified several specific genetic polymorphisms that have been most researched and, at this time, appear to have the greatest clinical significance on NAFLD and similar hepatic diseases. These were further investigated to assess their specific effects on disease onset and progression and the mechanisms by which these effects ***: We focus particularly on genetic polymorphisms of the following genes: PNPLA3, particularly the p. I148M variant, TM6SF2, particularly the p. E167K variant, and on variants in FTO, LIPA, IFNλ4, and iron metabolism, specifically focusing on HFE, and HMOX-1. We discuss the effect of these genetic variations and their resultant protein variants on the onset of fatty liver disease and its severity, including the effect on likelihood of progression to cirrhosis and hepatocellular carcinoma. While our principal focus is on NAFLD, we also discuss briefly effects of some of the variants on development and severity of other hepatic diseases, including hepatitis C and alcoholic liver disease. These results are briefly discussed in terms of clinical application and future potential for personalized ***: polymorphisms and genetic factors of several genes contribute to NAFLD and its end results. These genes hold keys to future improvements in diagnosis and management.
