Apolipoprotein C-III-1 activates lysosomal sphingomyelinase in vitro.

Apolipoprotein (apo)C-III-1 from human very low density lipoprotein stimulates 14-fold the activity of lysosomal sphingomyelinase from human fibroblasts. At the sphingomyelin concentrations tested, maximal stimulation was obtained with 5 microM apoC-III-1 or apoC mixture. Apolipoproteins A-I, A-II, B, and C-I conferred little or no stimulation. Sphingomyelinase was stimulated 20-fold by lysopho...

Amyloid Triangles, Squares, and Loops of Apolipoprotein C-III

While a significant component of atherosclerotic plaques has been characterized as amyloid, the specific proteins remain to be fully identified. Probable amyloidogenic proteins are apolipoproteins (Apos), which are vital for the formation and function of lipoproteins. ApoCIII is an abundant protein implicated in atherosclerosis, and we show it forms a ribbonlike looped amyloid, strikingly simil...

Apolipoprotein C-III SstI genotypes modulate exercise-induced hypotriglyceridemia.

PURPOSE To investigate whether the efficacy of exercise as an antitriglyceridemic treatment was dependent on the apolipoprotein (apo) C-III SstI gene polymorphism. METHODS A subgroup of 100 Korean men, who were prescreened by genotypes (S1S1 = 40, S1S2 = 40, S2S2 = 20), participated in a 6-d moderate-exercise intervention using either a motor-driven treadmill or a cycle ergometer. Height and ...

Apolipoprotein C-III: understanding an emerging cardiovascular risk factor.

The concurrence of visceral obesity, insulin resistance and dyslipidaemia comprises the concept of the metabolic syndrome. The metabolic syndrome is an escalating problem in developed and developing societies that tracks with the obesity epidemic. Dyslipidaemia in the metabolic syndrome is potently atherogenic and, hence, is a major risk factor for CVD (cardiovascular disease) in these subjects...
