Abstract
We explored the association between dietary manganese intake and the risk of liver cancer in 14,517 men and 21,583 women who participated in the Japan Collaborative Cohort Study for Cancer Risk Assessment. We assessed dietary manganese intake using a food frequency questionnaire and incident liver cancer by reviewing cancer registries. According to manganese intake, we estimated the liver cancer risk by Cox regression analyses. During the 513,657 person-year follow-ups within a median of 17.9 years of 36,100 participants, there were 239 incident cases of liver cancer. The multivariable hazard ratio (HR) (95% confidence interval [CI]; P-trend) for liver cancer risk in the highest vs. the lowest quintiles of dietary manganese intake was 0.56 (0.32-0.99; 0.04) in men and 1.16 (0.56-2.40; 0.79) in women; P-interaction = 0.06. The history of liver disease modified the observed association in men (P-interaction = 0.02), in which the multivariable HR (95%CI) of liver cancer risk comparing the highest vs. lowest quintiles of dietary manganese intake was 0.32 (0.14-0.74) in Japanese men without a history of liver disease, while it was 1.54 (0.62-3.79) in men with a history of liver disease. In conclusion, a higher dietary manganese intake was associated with a lower risk of liver cancer in men without a history of liver disease.

Abstract
The maternal epigenome may be responsive to prenatal metals exposures. We tested whether metals are associated with concurrent differential maternal whole blood DNA methylation. In the Early Autism Risk Longitudinal Investigation cohort, we measured first or second trimester maternal blood metals concentrations (cadmium, lead, mercury, manganese, and selenium) using inductively coupled plasma mass spectrometry. DNA methylation in maternal whole blood was measured on the Illumina 450 K array. A subset sample of 97 women had both measures available for analysis, all of whom did not report smoking during pregnancy. Linear regression was used to test for site-specific associations between individual metals and DNA methylation, adjusting for cell type composition and confounding variables. Discovery gene ontology analysis was conducted on the top 1,000 sites associated with each metal. We observed hypermethylation at 11 DNA methylation sites associated with lead (FDR False Discovery Rate q-value <0.1), near the genes CYP24A1, ASCL2, FAT1, SNX31, NKX6-2, LRC4C, BMP7, HOXC11, PCDH7, ZSCAN18, and VIPR2. Lead-associated sites were enriched (FDR q-value <0.1) for the pathways cell adhesion, nervous system development, and calcium ion binding. Manganese was associated with hypermethylation at four DNA methylation sites (FDR q-value <0.1), one of which was near the gene ARID2. Manganese-associated sites were enriched for cellular metabolism pathways (FDR q-value<0.1). Effect estimates for DNA methylation sites associated (p < 0.05) with cadmium, lead, and manganese were highly correlated (Pearson ρ > 0.86). DNA methylation sites associated with lead and manganese may be potential biomarkers of exposure or implicate downstream gene pathways.
