As a first step, we measured LTL and mtDNA copy number in 96 individuals for which a blood sample had been collected twice with an interval of 15 years.According to the intraclass correlation (ICC), we found very good stability over the time period for both measurements, with ICCs of 0.63 for LTL and 0.60 for mtDNA copy number. In the analysis of the entire study sample, we observed that longer LTL was strongly associated with increased risk of BC (OR 2.71, 95% CI 1.58-4.65, p = 3.07 × 10- 4 for highest vs. lowest quartile; OR 3.20, 95% CI 1.57-6.55, p = 1.41 × 10- 3 as a continuous variable). We did not find any association between mtDNA copy number and BC risk; however, when considering only the functional copies, we observed an increased risk of developing estrogen receptor-positive BC (OR 2.47, 95% CI 1.05-5.80, p = 0.04 for highest vs. lowest quartile).We observed a very good correlation between the markers over a period of 15 years. We confirm a role of LTL in BC carcinogenesis and suggest an effect of mtDNA copy number on BC risk. 000132793 536__ $$0G:(DE-HGF)POF3-313$$a313 - Cancer risk factors and prevention (POF3-313)$$cPOF3-313$$fPOF III$$x0 000132793 588__ $$aDataset connected to CrossRef, PubMed, 000132793 7001_ $$0P:(DE-He78)9c1a5b028ca0ab2ef3468a9266f81f63$$aBarrdahl, Myrto$$b1$$udkfz 000132793 7001_ $$aSantoro, Aurelia$$b2 000132793 7001_ $$aSeveri, Gianluca$$b3 000132793 7001_ $$aBaglietto, Laura$$b4 000132793 7001_ $$aOmichessan, Hanane$$b5 000132793 7001_ $$aTumino, Rosario$$b6 000132793 7001_ $$aBueno-de-Mesquita, H B As$$b7 000132793 7001_ $$aPeeters, Petra H$$b8 000132793 7001_ $$aWeiderpass, Elisabete$$b9 000132793 7001_ $$aChirlaque, Maria-Dolores$$b10 000132793 7001_ $$aRodríguez-Barranco, Miguel$$b11 000132793 7001_ $$aAgudo, Antonio$$b12 000132793 7001_ $$aGunter, Marc$$b13 000132793 7001_ $$aDossus, Laure$$b14 000132793 7001_ $$aKrogh, Vittorio$$b15 000132793 7001_ $$aMatullo, Giuseppe$$b16 000132793 7001_ $$aTrichopoulou, Antonia$$b17 000132793 7001_ $$aTravis, Ruth C$$b18 000132793 7001_ $$0P:(DE-He78)5323704270b6393dcea70186ffd86bca$$aCanzian, Federico$$b19$$udkfz 000132793 7001_ $$0P:(DE-He78)4b2dc91c9d1ac33a1c0e0777d0c1697a$$aKaaks, Rudolf$$b20$$eLast author$$udkfz 000132793 773__ $$0PERI:(DE-600)2041618-0$$a10.1186/s13058-018-0955-5$$gVol. 20, no. 1, p. 29$$n1$$p29$$tBreast cancer research$$v20$$x1465-542X$$y2018 000132793 909CO $$ooai:inrepo02.dkfz.de:132793$$pVDB 000132793 9101_ $$0I:(DE-588b)2036810-0$$6P:(DE-He78)9c1a5b028ca0ab2ef3468a9266f81f63$$aDeutsches Krebsforschungszentrum$$b1$$kDKFZ 000132793 9101_ $$0I:(DE-588b)2036810-0$$6P:(DE-He78)5323704270b6393dcea70186ffd86bca$$aDeutsches Krebsforschungszentrum$$b19$$kDKFZ 000132793 9101_ $$0I:(DE-588b)2036810-0$$6P:(DE-He78)4b2dc91c9d1ac33a1c0e0777d0c1697a$$aDeutsches Krebsforschungszentrum$$b20$$kDKFZ 000132793 9131_ $$0G:(DE-HGF)POF3-313$$1G:(DE-HGF)POF3-310$$2G:(DE-HGF)POF3-300$$3G:(DE-HGF)POF3$$4G:(DE-HGF)POF$$aDE-HGF$$bGesundheit$$lKrebsforschung$$vCancer risk factors and prevention$$x0 000132793 9141_ $$y2018 000132793 915__ $$0StatID:(DE-HGF)0200$$2StatID$$aDBCoverage$$bSCOPUS 000132793 915__ $$0StatID:(DE-HGF)0300$$2StatID$$aDBCoverage$$bMedline 000132793 915__ $$0StatID:(DE-HGF)0310$$2StatID$$aDBCoverage$$bNCBI Molecular Biology Database 000132793 915__ $$0StatID:(DE-HGF)0501$$2StatID$$aDBCoverage$$bDOAJ Seal 000132793 915__ $$0StatID:(DE-HGF)0500$$2StatID$$aDBCoverage$$bDOAJ 000132793 915__ $$0LIC:(DE-HGF)CCBYNV$$2V:(DE-HGF)$$aCreative Commons Attribution CC BY (No Version)$$bDOAJ 000132793 915__ $$0StatID:(DE-HGF)0100$$2StatID$$aJCR$$bBREAST CANCER RES : 2015 000132793 915__ $$0StatID:(DE-HGF)0199$$2StatID$$aDBCoverage$$bThomson Reuters Master Journal List 000132793 915__ $$0StatID:(DE-HGF)0110$$2StatID$$aWoS$$bScience Citation Index 000132793 915__ $$0StatID:(DE-HGF)0150$$2StatID$$aDBCoverage$$bWeb of Science Core Collection 000132793 915__ $$0StatID:(DE-HGF)0111$$2StatID$$aWoS$$bScience Citation Index Expanded 000132793 915__ $$0StatID:(DE-HGF)1110$$2StatID$$aDBCoverage$$bCurrent Contents - Clinical Medicine 000132793 915__ $$0StatID:(DE-HGF)9905$$2StatID$$aIF >= 5$$bBREAST CANCER RES : 2015 000132793 9201_ $$0I:(DE-He78)C055-20160331$$kC055$$lGenomische Epidemiologie$$x0 000132793 9201_ $$0I:(DE-He78)C020-20160331$$kC020$$lEpidemiologie von Krebserkrankungen$$x1 000132793 980__ $$ajournal 000132793 980__ $$aVDB 000132793 980__ $$aI:(DE-He78)C055-20160331 000132793 980__ $$aI:(DE-He78)C020-20160331 000132793 980__ $$aUNRESTRICTED
