12,13-diHOME protects against the age-related decline in cardiovascular function via attenuation of CaMKII.

ABSTRACT: Aging poses significant challenges to cardiovascular health necessitating novel therapeutic approaches. This study investigates the potential of the brown adipose tissue (BAT) derived lipokine 12,13-diHOME to mitigate age-induced impairments in cardiovascular function. Analysis of human and rodent plasma signaling lipids reveals a decline in 12,13-diHOME levels with age. Transplantation of BAT or sustained upregulation of 12,13-diHOME effectively preserved cardiac function in aged male and female mice. Bulk RNA-Seq of hearts from aged mice reveals significant increases in pathways involved in ER stress and fibrosis which were partially attenuated by BAT transplantation or sustained upregulation of 12,13-diHOME. Mechanistically, in vivo and in vitro models demonstrate that 12,13-diHOME alle
