To elucidate the contribution of glutathione S-transferase (GST) and glutathione peroxidase (GPx) to the protection against oxidative stress in rat brain, we prepared GST and GPx from newborn rat liver, brain and cultured astrocytes, and investigated

A lysosomal type alpha-D-mannosidase was successfully purified by DEAE-Sephacel, Red-Amicon and Superdex 200 column chromatographies from porcine cauda epididymal fluid. The purified enzyme consisted of 63 and 51 kDa subunits at equimolar amounts. It

The cDNA encoding a mouse homologue of porcine epididymis-specific 135kDa alpha-D-mannosidase (MAN2B2, D28521) was cloned from the mouse testis cDNA library. It was found that 1018 amino acids were coded in its open reading frame, and 62% of the amin

The epididymis-specific glutathione peroxidase was purified from the porcine cauda epididymal fluid in order to analyze its enzymatic activity and roles in the epididymis. The purified protein was found to consist of four identical 23 kDa subunits. T

The proteins which are secreted from the restricted part of the epididymis are suggested to sustain sperm maturation. In porcine species, as the potential abilities of sperm for movement and fertilization greatly increase in the corpus epididymis, th

To investigate the function of antioxidant enzymes in intact cells, we examined the removal of extracellular H2O2 by cultured fibroblasts (IMR-90). H2O2 concentration dependence of the reaction rate was interpreted as that the process involves two ki

The synthesis of 23 kDa protein was enhanced when mouse peritoneal macrophages were exposed to oxidative agents such as hydrogen peroxide and menadione, or to sulfhydryl-reactive agents such as diethylmaleate, cadmium chloride and sodium arsenite. Af

Endothelin-1 (ET-1), a 21 amino-acid potent vasoconstrictor peptide, is produced from the biologically inactive intermediate big ET-1 via an endoproteolytic cleavage between Trp-21 and Val-22 by endothelin converting enzyme (ECE). cDNA sequence analy

Comparative studies of 45Ca(2+)-transport across the plasma membrane were performed using porcine caput, corpus and cauda epididymal sperm. The Ca(2+)-uptake is dependent on the presence of the substrates for respiration and is sensitive to verapamil

The uptake of L-cystine into cultured human umbilical vein endothelial cells was Na+ independent and inhibited competitively by glutamate. It is concluded that the uptake of cystine in endothelial cells is mediated by system x-c. The contents of glut
