LPIN1 and type 2 diabetes mellitus: Compared to the MC group, intervention with blueberry polyphenols resulted in varying degrees of decreased expression of the cell death-inducing DNA fragmentation factor-alpha-like effector a (Cidea), Cidec, Perilipin 4 (Plin4), Perilipin 5 (Plin5), lipin 1 (Lpin1) and lipin (Lpin2) genes in the livers of mice, indicating an improvement in hepatic lipid droplet formation and metabolic homeostasis in T2D mice.
