Ferroptosis: The Initiation Process of Lipid Peroxidation in Muscle Food
AntioxidantsAnimal slaughtering causes the cessation of oxygen delivery and that of nutrients such as cystine, glucose and others to muscle cells. In muscle cells, the changes in oxygen level and pH cause mitochondria, the endoplasmic reticulum, xanthine oxidase and

Activities of Cytosolic Glutathione Peroxidase and Phospholipid Hydroperoxide Glutathione Peroxidase in Rat Salivary Glands [PDF]
ラット唾液腺における細胞質型グルタチオンペルオキシダーゼ(cGPx)とリン脂質ヒドロペルオキシドグルタチオンペルオキシダーゼ(PHGPx)の分布を検討した。三大唾液腺のうち、顎下腺と舌下腺では高いcGPx活性が認められたが、耳下腺では他の唾液腺の約30%の活性であった。cGPxは主として細胞質画分に分布した。一方、PHGPx活性は顎下腺、耳下腺、舌下腺の順に高い活性を示した。舌下腺のPHGPx活性はcGPx活性とは異なり、他の唾液腺よりかなり低かった。PHGPx活性は細胞質画分、ミトコンドリア画分 ...

Identification of cDNAS encoding plastid-targeted glutathione peroxidase [PDF]
A cDNA was isolated from pea leaf RNA which encodes a phospholipid hydroperoxide glutathione peroxidase (PHGPX; E.C. 1.1.1.1.9). The N-terminal section of this PHGPX encodes a recognisable chloroplast transit peptide. Efficient import in vitro of the pre-

The selenoenzyme phospholipid hydroperoxide glutathione peroxidase
Biochimica Et Biophysica Acta - General Subjects, 1985The reduction of membrane-bound hydroperoxides is a major factor acting against lipid peroxidation in living systems. This paper presents the characterization of the previously described 'peroxidation-inhibiting protein' as a 'phospholipid hydroperoxide glutathione peroxidase'. The enzyme is a monomer of 23 kDa (SDS-polyacrylamide gel electrophoresis).

Physiological role of phospholipid hydroperoxide glutathione peroxidase in mammals [PDF]
bchm, 2007 Abstract The redox enzyme phospholipid hydroperoxide glutathione peroxidase (PHGPx) has emerged as one of the most significant selenoenzymes in mammals, corroborated by early embryonic lethality of PHGPx null mice. PHGPx is one of five selenium-dependent glutathione peroxidases and the second glutathione peroxidase to be discovered in ...

Testis Glutathione Peroxidase and Phospholipid Hydroperoxide Glutathione Peroxidase Activities in Aminoguanidine-Treated Diabetic Rats [PDF]
Archives of Biochemistry and Biophysics, 2000 Severe steroidogenic and spermatogenic alterations are reported in association with diabetic manifestations in humans and experimental animals. This study was planned to determine whether oxidative stress is involved in diabetes-induced alterations in the testes. Diabetes was induced in male rats by injection of 50 mg/kg of streptozotocin (STZ).

Distribution of phospholipid hydroperoxide glutathione peroxidase (PHGPx) in rat testis mitochondria
Biochimica Et Biophysica Acta - Biomembranes, 1994The distribution of phospholipid hydroperoxide glutathione peroxidase (PHGPx) in isolated rat testis mitochondria was investigated, using a reverse sucrose density gradient centrifugation procedure for the separation of the inner and outer membranes and the contact sites between the two membranes. The results indicate that PHGPx is largely localized in
