Fibroblast growth factor (FGF) 21 deficiency worsens lipid profiles and exacerbates inflammation in apolipoprotein (apo) E−/− mice. ApoE−/−FGF21−/− (DKO) and apoE−/− mice fed with standard chow were euthanized at 24 weeks after birth. Plasma samples were collected for measurement of triglycerides (TG; A), total cholesterol (TC; B), high-density lipoprotein (HDL; C), low-density lipoprotein (LDL; D), and very LDL (VLDL; E). F, The mRNA expression of intercellular adhesion molecule-1 (ICAM-1) vascular cell adhesion protein-1 (VCAM-1), tumor necrosis factor-α (TNFα), and monocyte chemotactic protein-1 (MCP-1) in aortic tissue, as well as (G–J) plasma levels of these proinflammatory chemokines and cytokines, were measured with real-time polymerase chain reaction and ELISA, respectively. n=6 to 7. Data are presented as dot plots with the line indicating the median. The Mann-Whitney U test was used for comparison of 2 groups.
