| Outline of Final Research Achievements |
In 126 non-diabetic volunteers, multivariable linear regression analysis showed serum apoL1 positively correlated with body mass index and triglyceride, and negatively correlated with HDL cholesterol. Circulating apoL1 significantly elevates in metabolic syndrome (MS) compared with non-MS, and positively associates with HOMA-IR, thus suggesting the involvement of apoL1 in dyslipidemia in MS. Next, FPLC analysis showed the significant increase of activated apoL1 in large HDL purified from MS subjects. ApoL1/HDL cholesterol ratio is inversely associated with serum oxidative metabolites. In 36 type 2 diabetic patients, serum apoL1 significantly increases in MS, with the negative association with urine 8OHdG/Cr ratio and urine albuminuria. In 59 chronic kidney disease patients, apoL1 showed the inverse correlation with urine L-FABP. Taken together, the increased activated apoL1 on HDL may be associated with anti-oxidative activity of HDL particles, which contributes to renoprotection.
