  • PNPLA3 1148M Variant Influences Circulating Retinol in Adults with Nonalcoholic Fatty Liver Disease or Obesity
  • 2015
  • In: Journal of Nutrition. - : Elsevier BV. - 0022-3166. ; 145:8, s. 1687-1691
  • Journal article (peer-reviewed)abstract
    • Background: Retinal is a lipid-soluble essential nutrient that is stored as retinyl esters in lipid droplets of hepatic stellate cells. Patatin-like phospholipase domain-containing 3 (PNPLA3), through its retinyl-palmitate lipase activity, releases retinol from lipid droplets in hepatic stellate cells in vitro and ex vivo. We have shown that the genetic variant 1148M (rs738409) reduces the PNPLA3 retinyl-palmitate lipase activity. Objective: The aim of the present genetic association study was to test whether overweight/obese carriers of the PNPLA3 148M mutant allele had lower circulating concentrations of retinal than individuals who are homozygous for the 1481 allele. Methods: PNPLA31148M (rs738409) was genotyped by Taqman assay in 76 overweight/obese individuals [BMI (kg/m(2))>= 25; mean +/- SD age: 59.7 +/- 11.4 y; male gender: 70%] with a histologic diagnosis of nonalcoholic fatty liver disease (NAFLD; namely the Milan NAFLD cohort) and in 413 obese men (BMI >= 30; mean SD age: 57.1 +/- 4.9 y) from the alpha-Tocopherol, (beta-Carotene Cancer Prevention (ATBC) Study. Serum concentrations of retinal and alpha-tocopherol were measured by HPLC in both cohorts. beta-Carotene concentrations in the ATBC study were measured by using HPLC. Results: The PNPLA3 148M mutant allele was associated with lower fasting circulating concentrations of retinal (beta = -0.289, P = 0.03) in adults with NAFLD (Milan NAFLD cohort). The PNPLA3148M mutant allele was also associated with lower fasting circulating concentrations of retinal in adults with a BMI >= 30 (ATBC study; [beta = -0.043, P = 0.041. Conclusion: We showed for the first time, to our knowledge, that carriers of the PNPLA3148M allele with either fatty liver plus obesity or obesity alone have lower fasting circulating retinol concentrations.

  • Genetically Determined Height and Risk of Non-hodgkin Lymphoma
  • 2020
  • In: Frontiers in Oncology. - : FRONTIERS MEDIA SA. - 2234-943X. ; 9
  • Journal article (peer-reviewed)abstract
    • Although the evidence is not consistent, epidemiologic studies have suggested that taller adult height may be associated with an increased risk of some non-Hodgkin lymphoma (NHL) subtypes. Height is largely determined by genetic factors, but how these genetic factors may contribute to NHL risk is unknown. We investigated the relationship between genetic determinants of height and NHL risk using data from eight genome-wide association studies (GWAS) comprising 10,629 NHL cases, including 3,857 diffuse large B-cell lymphoma (DLBCL), 2,847 follicular lymphoma (FL), 3,100 chronic lymphocytic leukemia (CLL), and 825 marginal zone lymphoma (MZL) cases, and 9,505 controls of European ancestry. We evaluated genetically predicted height by constructing polygenic risk scores using 833 height-associated SNPs. We used logistic regression to estimate odds ratios (OR) and 95% confidence intervals (CI) for association between genetically determined height and the risk of four NHL subtypes in each GWAS and then used fixed-effect meta-analysis to combine subtype results across studies. We found suggestive evidence between taller genetically determined height and increased CLL risk (OR = 1.08, 95% CI = 1.00-1.17, p = 0.049), which was slightly stronger among women (OR = 1.15, 95% CI: 1.01-1.31, p = 0.036). No significant associations were observed with DLBCL, FL, or MZL. Our findings suggest that there may be some shared genetic factors between CLL and height, but other endogenous or environmental factors may underlie reported epidemiologic height associations with other subtypes.

  • Circulating high sensitivity C reactive protein concentrations and risk of lung cancer : nested case-control study within Lung Cancer Cohort Consortium
  • 2019
  • In: The BMJ. - : BMJ Publishing Group Ltd. - 1756-1833 .- 0959-8138. ; 364
  • Journal article (peer-reviewed)abstract
    • Objectives To conduct a comprehensive analysis of prospectively measured circulating high sensitivity C reactive protein (hsCRP) concentration and risk of lung cancer overall, by smoking status (never, former, and current smokers), and histological sub-type.Design Nested case-control study.Setting 20 population based cohort studies in Asia, Europe, Australia, and the United States.Participants 5299 patients with incident lung cancer, with individually incidence density matched controls.Exposure Circulating hsCRP concentrations in prediagnostic serum or plasma samples.Main outcome measure Incident lung cancer diagnosis.Results A positive association between circulating hsCRP concentration and the risk of lung cancer for current (odds ratio associated with a doubling in hsCRP concentration 1.09, 95% confidence interval 1.05 to 1.13) and former smokers (1.09, 1.04 to 1.14) was observed, but not for never smokers (P<0.01 for interaction). This association was strong and consistent across all histological subtypes, except for adenocarcinoma, which was not strongly associated with hsCRP concentration regardless of smoking status (odds ratio for adenocarcinoma overall 0.97, 95% confidence interval 0.94 to 1.01). The association between circulating hsCRP concentration and the risk of lung cancer was strongest in the first two years of follow-up for former and current smokers. Including hsCRP concentration in a risk model, in addition to smoking based variables, did not improve risk discrimination overall, but slightly improved discrimination for cancers diagnosed in the first two years of follow-up.Conclusions Former and current smokers with higher circulating hsCRP concentrations had a higher risk of lung cancer overall. Circulating hsCRP concentration was not associated with the risk of lung adenocarcinoma. Circulating hsCRP concentration could be a prediagnostic marker of lung cancer rather than a causal risk factor.

  • A genome-wide association study identifies pancreatic cancer susceptibility loci on chromosomes 13q22.1, 1q32.1 and 5p15.33
  • 2010
  • In: Nature Genetics. - : Springer Science and Business Media LLC. - 1061-4036 .- 1546-1718. ; 42:3, s. 224-228
  • Journal article (peer-reviewed)abstract
    • We conducted a genome-wide association study of pancreatic cancer in 3,851 affected individuals (cases) and 3,934 unaffected controls drawn from 12 prospective cohort studies and 8 case-control studies. Based on a logistic regression model for genotype trend effect that was adjusted for study, age, sex, self-described ancestry and five principal components, we identified eight SNPs that map to three loci on chromosomes 13q22.1, 1q32.1 and 5p15.33. Two correlated SNPs, rs9543325 (P = 3.27 x 10(-11), per-allele odds ratio (OR) 1.26, 95% CI 1.18-1.35) and rs9564966 (P = 5.86 x 10(-8), per-allele OR 1.21, 95% CI 1.13-1.30), map to a nongenic region on chromosome 13q22.1. Five SNPs on 1q32.1 map to NR5A2, and the strongest signal was at rs3790844 (P = 2.45 x 10(-10), per-allele OR 0.77, 95% CI 0.71-0.84). A single SNP, rs401681 (P = 3.66 x 10(-7), per-allele OR 1.19, 95% CI 1.11-1.27), maps to the CLPTM1L-TERT locus on 5p15.33, which is associated with multiple cancers. Our study has identified common susceptibility loci for pancreatic cancer that warrant follow-up studies.
