Given that {\textless}br{\textgreater}obesity strongly influences circulating protein levels, we investigated proteins {\textless}br{\textgreater}mediating the effects of obesity on coronary artery disease, stroke and type 2 {\textless}br{\textgreater}diabetes. By integrating two-step proteome-wide Mendelian randomization, {\textless}br{\textgreater}colocalization, epigenomics and single-cell RNA sequencing, we identified {\textless}br{\textgreater}five mediators and prioritized collagen type VI $\alpha$3 (COL6A3). COL6A3 levels {\textless}br{\textgreater}were strongly increased by body mass index and increased coronary artery {\textless}br{\textgreater}disease risk. Notably, the carboxyl terminus product of COL6A3, endotrophin, {\textless}br{\textgreater}drove this effect. COL6A3 was highly expressed in disease-relevant cell types {\textless}br{\textgreater}and tissues. Finally, we found that body fat reduction could reduce plasma {\textless}br{\textgreater}levels of COL6A3-derived endotrophin, indicating a tractable way to modify {\textless}br{\textgreater}endotrophin levels. In summary, we provide actionable insights into how {\textless}br{\textgreater}circulating proteins mediate the effects of obesity on cardiometabolic {\textless}br{\textgreater}diseases and prioritize endotrophin as a potential therapeutic target.}}, journal = {{Nature Genetics}}, volume = {57}, number = {2}, pages = {345--357}, }
