Task: Question Generation
Input (English): Recent studies have suggested that apoprotein (apo) CI in very low-density lipoprotein (VLDL) plays an important role in causing hypertriglyceridemia independent of apo CIII, which is associated with coronary heart disease (CHD). Because the incidence of CHD is increased in diabetic patients and is even higher when diabetic nephropathy is developed, we measured apo CI levels in VLDL from type 2 diabetic patients, with various degree of nephropathy, and compared the results with those for healthy controls or nondiabetic patients with chronic renal failure (CRF).', 'This study enrolled healthy control subjects, type 2 diabetic patients with normoalbuminuria, microalbuminuria, overt proteinuria, and CRF on hemodialysis and nondiabetic hemodialysis patients. VLDL (density <1.006) was separated by ultracentrifugation. Then the apo CI, CIII, and B concentrations in VLDL were measured by enzyme-linked immunosorbent assay (ELISA).', 'The apo CI, CIII, and B concentrations in VLDL were respectively 3-, 2-, and 2-fold higher, respectively, in diabetic patients with overt proteinuria than in controls. Hemodialysis patients with diabetic nephropathy had levels of apo CI, CIII, and B in VLDL that were 2.6-, 2.7- and 2-fold higher, respectively, than those in controls. Nondiabetic hemodialysis patients also had a 2.7-fold higher level of VLDL apo CIII, whereas VLDL apo CI and VLDL apo B were not significantly increased. VLDL apo CI was significantly correlated with VLDL apo B independently of VLDL apo CIII level.
Output (English): Is very low-density lipoprotein-apoprotein CI increased in diabetic nephropathy : comparison with apoprotein CIII?
