Abstract/OtherAbstract:

Oxidation and inflammation are leading causes of nearly all chronic metabolic disorders, and play major roles in cardiovascular disease, cancer, and chronic age-dependent disease. High-density lipoprotein (HDL) and apolipoprotein (apo) A-I have strong antioxidant and anti-inflammatory properties in the plasma. Fructose-induced non-enzymatic glycation of apoA-I can lead to the production of dysfunctional apoA-I and HDL. To compare the physiologic effects of dysfunctional apoA-I and HDL, reconstituted HDL containing native apoA-I (nA-I) or glycated apoA-I (gA-I) was injected into zebrafish embryos in the presence of inflammatory molecules. Co-injection of reconstituted HDL containing VLDL and LDL gA-I (gA-I-rHDL) and lipopolysaccaride (LPS) resulted in acute embryo deaths, while rHDL containing nA-I (nA-I-rHDL) and LPS resulted in significantly enhanced survival. Co-injection of oxidized LDL (oxLDL) and nA-I-rHDL improved embryo survival, while co-injection of oxLDL and gA-I-rHDL aggravated inflammatory deaths. Furthermore, co-injection of oxLDL and HDL(2) (5 ng of protein) or HDL(3) (15 ng of protein) from the young group (22 ± 2 years old) showed significantly increased embryo survival compared with the same co-injection of HDL from the elderly group (71 ± 4 years old). In conclusion, our assay system provides a rapid and economic method to screen antioxidant and anti-inflammatory agents using zebrafish embryos. |
