Methods: The following biomarkers were assessed in 207 predominantly healthy participants at baseline and after 4 months: MMF, TGF-beta, suPAR and clusterin. Results: Intraclass correlation coefficients (95\% CIs) ranged from good for TGF-beta (0.75 [95\% CI: 0.33-0.90]) to excellent for MMF (0.81 [95\% CI: 0.64-0.90]), clusterin (0.83 [95\% CI: 0.78-0.87]) and suPAR (0.91 [95\% CI: 0.88-0.93]). Measurement of TGF-beta was challenged by the large number of values below the detection limit. Conclusion: Single measurements of suPAR, clusterin and MMF could serve as feasible and reliable biomarkers of immune-inflammatory pathways in biomedical research.}, language = {en} } @misc{PonceSchererBoekstegersetal.2019, author = {Ponce, Carol Barahona and Scherer, Dominique and Boekstegers, Felix and Garate-Calderon, Valentina and Jenab, Mazda and Aleksandrova, Krasimira and Katzke, Verena and Weiderpass, Elisabete and Bonet, Catalina and Moradi, Tahereh and Fischer, Krista and Bossers, Willem and Brenner, Hermann and Sch{\"o}ttker, Ben and Holleczek, Bernd and Hveem, Kristian and Eklund, Niina and Voelker, Uwe and Waldenberger, Melanie and Bermejo, Justo Lorenzo}, title = {Arsenic and gallbladder cancer risk}, series = {International journal of cancer}, volume = {146}, journal = {International journal of cancer}, number = {9}, publisher = {Wiley}, address = {Hoboken}, issn = {0020-7136}, doi = {10.1002/ijc.32837}, pages = {2648 -- 2650}, year = {2019}, language = {en} } @article{HarmsScalbertZamoraRosetal.2019, author = {Harms, Laura M. and Scalbert, Augustin and Zamora-Ros, Raul and Rinaldi, Sabina and Jenab, Mazda and Murphy, Neil and Achaintre, David and Tj{\o}nneland, Anne and Olsen, Anja and Overvad, Kim and Aleksandrova, Krasimira}, title = {Plasma polyphenols associated with lower high-sensitivity C-reactive protein concentrations}, series = {British Journal of Nutrition}, volume = {123}, journal = {British Journal of Nutrition}, number = {2}, publisher = {Cambridge University Press}, address = {Cambridge}, issn = {0007-1145}, doi = {10.1017/S0007114519002538}, pages = {198 -- 208}, year = {2019}, abstract = {Experimental studies have reported on the anti-inflammatory properties of polyphenols. However, results from epidemiological investigations have been inconsistent and especially studies using biomarkers for assessment of polyphenol intake have been scant. We aimed to characterise the association between plasma concentrations of thirty-five polyphenol compounds and low-grade systemic inflammation state as measured by high-sensitivity C-reactive protein (hsCRP). A cross-sectional data analysis was performed based on 315 participants in the European Prospective Investigation into Cancer and Nutrition cohort with available measurements of plasma polyphenols and hsCRP. In logistic regression analysis, the OR and 95 \% CI of elevated serum hsCRP (>3 mg/l) were calculated within quartiles and per standard deviation higher level of plasma polyphenol concentrations. In a multivariable-adjusted model, the sum of plasma concentrations of all polyphenols measured (per standard deviation) was associated with 29 (95 \% CI 50, 1) \% lower odds of elevated hsCRP. In the class of flavonoids, daidzein was inversely associated with elevated hsCRP (OR 0 center dot 66, 95 \% CI 0 center dot 46, 0 center dot 96). Among phenolic acids, statistically significant associations were observed for 3,5-dihydroxyphenylpropionic acid (OR 0 center dot 58, 95 \% CI 0 center dot 39, 0 center dot 86), 3,4-dihydroxyphenylpropionic acid (OR 0 center dot 63, 95 \% CI 0 center dot 46, 0 center dot 87), ferulic acid (OR 0 center dot 65, 95 \% CI 0 center dot 44, 0 center dot 96) and caffeic acid (OR 0 center dot 69, 95 \% CI 0 center dot 51, 0 center dot 93). The odds of elevated hsCRP were significantly reduced for hydroxytyrosol (OR 0 center dot 67, 95 \% CI 0 center dot 48, 0 center dot 93). The present study showed that polyphenol biomarkers are associated with lower odds of elevated hsCRP. Whether diet rich in bioactive polyphenol compounds could be an effective strategy to prevent or modulate deleterious health effects of inflammation should be addressed by further well-powered longitudinal studies.}, language = {en} } @article{EichelmannSchulzeWittenbecheretal.2019, author = {Eichelmann, Fabian and Schulze, Matthias Bernd and Wittenbecher, Clemens and Menzel, Juliane and Weikert, Cornelia and di Giuseppe, Romina and Biemann, Ronald and Isermann, Berend and Fritsche, Andreas and Boeing, Heiner and Aleksandrova, Krasimira}, title = {Association of Chemerin Plasma Concentration With Risk of Colorectal Cancer}, series = {JAMA network open}, volume = {2}, journal = {JAMA network open}, number = {3}, publisher = {American Veterinary Medical Association}, address = {Chicago}, issn = {2574-3805}, doi = {10.1001/jamanetworkopen.2019.0896}, pages = {14}, year = {2019}, abstract = {IMPORTANCE Inflammatory processes have been suggested to have an important role in colorectal cancer (CRC) etiology. Chemerin is a recently discovered inflammatory biomarker thought to exert chemotactic, adipogenic, and angiogenic functions. However, its potential link with CRC has not been sufficiently explored. OBJECTIVE To evaluate the prospective association of circulating plasma chemerin concentrations with incident CRC. DESIGN, SETTING, AND PARTICIPANTS Prospective case-cohort study based on 27 548 initially healthy participants from the European Prospective Investigation Into Cancer and Nutrition (EPIC)-Potsdam cohort who were followed for up to 16 years. Baseline study information and samples were collected between August 23, 1994, and September 25, 1998. Recruitment was according to random registry sampling from the geographical area of Potsdam, Germany, and surrounding municipalities. The last date of study follow-up was May 10, 2010. Statistical analysis was conducted in 2018. MAIN OUTCOMES AND MEASURES Incident CRC, colon cancer, and rectal cancer. Baseline chemerin plasma concentrations were measured by enzyme-linked immunosorbent assay. CONCLUSIONS AND RELEVANCE This study found that the association between chemerin concentration and the risk of incident CRC was linear and independent of established CRC risk factors. Further studies are warranted to evaluate chemerin as a novel immune-inflammatory agent in colorectal carcinogenesis.}, language = {en} }
