Journal ArticleDOI

Mitochondrial DNA damage and dysfunction associated with oxidative stress in failing hearts after myocardial infarction.

TL;DR: It is hypothesized that ROS may induce mitochondrial DNA (mtDNA) damage, which leads to defects of mtDNA-encoded gene expression and respiratory chain complex enzymes and thus may contribute to the progression of left ventricular remodeling and failure after myocardial infarction.
Journal ArticleDOI

Four missense mutations identified in the protein S gene of thrombosis patients with protein S deficiency: effects on secretion and anticoagulant activity of protein S.

TL;DR: Results indicate that the Y595C and the K155E mutations are responsible for a secretion defect and a decreased anticoagulant activity of PS, respectively.
Journal ArticleDOI

The N-terminal region of the transmembrane domain of human erythrocyte band 3: Residues critical for membrane insertion and transport activity

TL;DR: It is found that the hydrophobic length of TM1 was critical for membrane insertion and that formation of a transport-active structure also depended on the presence of specific amino acid sequences in TM1.
Journal ArticleDOI

A case of congenital afibrinogenemia : Fibrinogen Hakata, a novel nonsense mutation of the fibrinogen γ-chain gene

TL;DR: Congenital afibrinogenemia due to a novel homozygous nonsense mutation of the fibrinagen gamma-chain gene, fibr inogen Hakata, was found in an 18-year-old Japanese girl who had received supplemental fibrInogen therapy since she was 4 months old.
