Mind The Gap: A Comparative Approach For Fixing Volcker, Learning From Liikanen, And Using Vickers To Repair The U.S. Banking System, Rachel Sereix

Duke Journal of Constitutional Law & Public Policy Sidebar

After the 2008 financial crisis, Congress, courts, and international banking agencies alike determined that their current banking infrastructures were inadequate to prevent such crises in the future. The Dodd-Frank Wall Street Reform Acttried to solve the problem by reducing derivatives-related risk through legislative provisions that increased capital and liquidity requirements for all banks. Yet, banks continued to find means to subvert the system and Congress remained relatively silent on the issue after the passage of Dodd-Frank—failing to amend Dodd-Frank in any meaningful way. Looking towards European peers for guidance about how to reform the United States’ banking regime has often …

We conducted cohort- and race-specific epigenome-wide association analyses of mitochondrial deoxyribonucleic acid (mtDNA) copy number (mtDNA CN) measured in whole blood from participants of African and European origins in five cohorts (n = 6182, mean age = 57-67 years, 65% women). In the meta-analysis of all the participants, we discovered 21 mtDNA CN-associated DNA methylation sites (CpG) (P < 1 × 10-7), with a 0.7-3.0 standard deviation increase (3 CpGs) or decrease (18 CpGs) in mtDNA CN corresponding to a 1% increase in DNA methylation. Several significant CpGs have been reported to be associated with at least two risk factors (e.g. chronological age or smoking) for cardiovascular disease (CVD). Five genes [PR/SET domain 16, nuclear receptor subfamily 1 group H member 3 (NR1H3), DNA repair protein, DNA polymerase kappa and decaprenyl-diphosphate synthase subunit 2], which harbor nine significant CpGs, are known to be involved in mitochondrial biosynthesis and functions. For example, NR1H3 encodes a transcription factor that is differentially expressed during an adipose tissue transition. The methylation level of cg09548275 in NR1H3 was negatively associated with mtDNA CN (effect size = -1.71, P = 4 × 10-8) and was positively associated with the NR1H3 expression level (effect size = 0.43, P = 0.0003), which indicates that the methylation level in NR1H3 may underlie the relationship between mtDNA CN, the NR1H3 transcription factor and energy expenditure. In summary, the study results suggest that mtDNA CN variation in whole blood is associated with DNA methylation levels in genes that are involved in a wide range of mitochondrial activities. These findings will help reveal molecular mechanisms between mtDNA CN and CVD.
