      Baglietto, Laura; Ponzi, Erica; Haycock, Philip; Hodge, Allison; Bianca Assumma, Manuela; Jung, Chol-Hee; Chung, Jessica; Fasanelli, Francesca; Guida, Florence; Campanella, Gianluca; Chadeau-Hyam, Marc; Grankvist, Kjell; Johansson, Mikael; Ala, Ugo; Provero, Paolo; Wong, Ee Ming; Joo, Jihoon; English, Dallas R.; Kazmi, Nabila; Lund, Eiliv; Faltus, Christian; Risch, Angela; Barrdahl, Myrto; Sandanger, Torkjel M; Southey, Melissa C.; Giles, Graham G.; Johansson, Mattias; Vineis, Paolo; Polidoro, Silvia; Relton, Caroline L.; Severi, Gianluca (Journal article; Tidsskriftartikkel; Peer reviewed, 2016-09-15)
      DNA methylation changes are associated with cigarette smoking. We used the Illumina Infinium HumanMethylation450 array to determine whether methylation in DNA from pre‐diagnostic, peripheral blood samples is associated with lung cancer risk. We used a case‐control study nested within the EPIC‐Italy cohort and a study within the MCCS cohort as discovery sets (a total of 552 case‐control pairs). We ...

      Aim of the study: A vast majority of human malignancies are associated with ageing, and age is a strong predictor of cancer risk. Recently, DNA methylation-based marker of ageing, known as ‘epigenetic clock’, has been linked with cancer risk factors. This study aimed to evaluate whether the epigenetic clock is associated with breast cancer risk susceptibility and to identify potential epigenetics-based ...

      Introduction: Breast cancer in situ (BCIS) diagnoses, a precursor lesion for invasive breast cancer, comprise about 20 % of all breast cancers (BC) in countries with screening programs. Family history of BC is considered one of the strongest risk factors for BCIS.<p><p>Methods: To evaluate the association of BC susceptibility loci with BCIS risk, we genotyped 39 single nucleotide polymorphisms (SNPs), ...

    • Genetic variation in the ADIPOQ gene, adiponectin concentrations and risk of colorectal cancer: a Mendelian Randomization analysis using data from three large cohort studies 

      Nimptsch, Katharina; Song, Mingyang; Aleksandrova, Krasimira; Katsoulis, Michail; Freisling, Heinz; Jenab, Mazda; Gunter, Marc J.; Tsilidis, Konstantinos K.; Weiderpass, Elisabete; Bueno-De-Mesquita, Hendrik Bastiaan; Chong, Dawn Q.; Jensen, Majken K.; Wu, Chunsen; Overvad, Kim; Kühn, Tilman; Barrdahl, Myrto; Melander, Olle; Jirström, Karin; Peeters, Petra H.; Sieri, Sabina; Panico, Salvatore; Cross, Amanda J.; Riboli, Elio; van Guelpen, Bethany; Myte, Robin; Huerta, José María; Rodriguez-Barranco, Miguel; Quirós, José Ramón; Dorronsoro, Miren; Tjønneland, Anne; Olsen, Anja; Travis, Ruth; Boutron-Ruault, Marie-Christine; Carbonnel, Franck; Severi, Gianluca; Bonet, Catalina; Palli, Domenico; Janke, Jürgen; Lee, Young-Ae; Boeing, Heiner; Giovannucci, Edward L.; Ogino, Shuji; Fuchs, Charles S.; Rimm, Eric; Wu, Kana; Chan, Andrew T.; Pischon, Tobias (Journal article; Manuskript; Tidsskriftartikkel; Peer reviewed; Preprint, 2017-05-26)
      Higher levels of circulating adiponectin have been related to lower risk of colorectal cancer in several prospective cohort studies, but it remains unclear whether this association may be causal. We aimed to improve causal inference in a Mendelian Randomization meta-analysis using nested case–control studies of the European Prospective Investigation into Cancer and Nutrition (EPIC, 623 cases, 623 ...

    • Identifying and correcting epigenetics measurements for systematic sources of variation 

      Perrier, Flavie; Novoloaca, Alexei; Ambatipudi, Srikant; Baglietto, Laura; Ghantous, Akram; Perduca, Vittorio; Barrdahl, Myrto; Harlid, Sophia; Ong, Ken K; Cardona, Alexia; Polidoro, Silvia; Nøst, Therese Haugdahl; Overvad, Kim; Omichessan, Hanane; Dollé, Martijn; Bamia, Christina; Huerta, José María; Vineis, Paolo; Herceg, Zdenko; Romieu, Isabelle; Ferrari, Pietro (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-03-21)
      <i>Background</i>: Methylation measures quantified by microarray techniques can be affected by systematic variation due to the technical processing of samples, which may compromise the accuracy of the measurement process and contribute to bias the estimate of the association under investigation. The quantification of the contribution of the systematic source of variation is challenging in datasets ...

    • Mitochondrial DNA copy number variation, leukocyte telomere length, and breast cancer risk in the European Prospective Investigation into Cancer and Nutrition (EPIC) study 

      Campa, Daniele; Barrdahl, Myrto; Santoro, Aurelia; Severi, Gianluca; Baglietto, Laura; Omichessan, Hanane; Tumino, Rosario; Bueno-De-Mesquita, Hendrik Bastiaan; Peeters, Petra H.; Weiderpass, Elisabete; Chirlaque, Maria-Dolores; Rodríguez-Barranco, Miguel; Agudo, Antonio; Gunter, Marc; Dossus, Laure; Krogh, Vittorio; Matullo, Giuseppe; Trichopoulou, Antonia; Travis, Ruth C.; Canzian, Federico; Kaaks, Rudolf (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-04-17)
      <p><i>Background</i>: Leukocyte telomere length (LTL) and mitochondrial genome (mtDNA) copy number and deletions have been proposed as risk markers for various cancer types, including breast cancer (BC).</p> <p><i>Methods</i>: To gain a more comprehensive picture on how these markers can modulate BC risk, alone or in conjunction, we performed simultaneous measurements of LTL and mtDNA copy number ...
