C-terminal sequence of amyloid-resistant type F apolipoprotein A-II inhibits amyloid fibril formation of apolipoprotein A-II in mice

C-terminal sequence of amyloid-resistant type F apolipoprotein A-II inhibits amyloid fibril formation of apolipoprotein A-II in mice.

In murine senile amyloidosis, misfolded serum apolipoprotein (apo) A-II deposits as amyloid fibrils (AApoAII) in a process associated with aging. Mouse strains carrying type C apoA-II (APOA2C) protein exhibit a high incidence of severe systemic amyloidosis. Previously, we showed that N- and C-terminal sequences of apoA-II protein are critical for polymerization into amyloid fibrils in vitro. He...

Sequence determinants of amyloid fibril formation.

The establishment of rules that link sequence and amyloid feature is critical for our understanding of misfolding diseases. To this end, we have performed a saturation mutagenesis analysis on the de novo-designed amyloid peptide STVIIE (1). The positional scanning mutagenesis has revealed that there is a position dependence on mutation of amyloid fibril formation and that both very tolerant and...

The Effect of Training Type on Hepatic Gene expressions of Apolipoprotein A‐I, and Apolipoprotein A‐II among Male Wistar Rats

Introdaction: Lipid metabolism disorders, especially raised levels of cholesterol and triglycerides increases the risk of atherosclerosis. This study aimed to investigate the effect of training type including submaximal continuous and high-intensity interval training on hepatic gene expression of Apolipoprotein A‐I, and Apolipoprotein A‐II in male Wistar rats.   Materials & Methods: This exper...

Methionine oxidation induces amyloid fibril formation by full-length apolipoprotein A-I.

Apolipoprotein A-I (apoA-I) is the major protein component of HDL, where it plays an important role in cholesterol transport. The deposition of apoA-I derived amyloid is associated with various hereditary systemic amyloidoses and atherosclerosis; however, very little is known about the mechanism of apoA-I amyloid formation. Methionine residues in apoA-I are oxidized via several mechanisms in vi...
