Phospholipid of the Rat Glomerular Basement Membrane
Phospholipids were found to be a constant component of rat glomerular basementmembrane preparations. The concentration fell during preparation of basement membrane by sonication of whole glomeruli, but then remained constant despite continued sonication. The proportions of the individual phospholipids were different from those of whole renal tissue or of isolated glomeruli. The basement-membran...
متن کاملGlomerulopathy in rats with streptozotocin diabetes. Accumulation of glomerular basement membrane analogous to human diabetic nephropathy
Glomeruli from streptozotocin-diabetic and age-matched nondiabetic rats were quantitatively isolated by a differential sieving technique. The insoluble glomerular basement membranes were purified following sonic disruption in the presence of proteolytic inhibitors. The yield of glomeruli and of glomerular basement membrane relative to the amount of renal cortex and the body weight of the animal...
متن کاملEffects of Aminoguanidine on Glomerular Basement Membrane Thickness and Anionic Charge in a Diabetic Rat Model
We investigated the effect of aminoguanidine (AG) administration on GBM thickness, glomerular heparan sulfate (HS) content, and urinary albumin and HS excretion in diabetic rats. After induction of diabetes, female Wistar rats were divided into 2 groups: Group AGDM (n = 11) received 1 g/L aminoguanidine bicarbonate in drinking water, group DC (n = 12) was given only tap water. Control rats rece...
متن کاملBovine Glomerular Basement Membrane
The collagenous domain of bovine glomerular basement membrane was excised in soluble form by limited pepsin digestion and characterized. The domain amounts to approximately 25% of the whole membrane by weight. The constituent polypeptides were studied using several electrophoresis systems and amino acid analysis. The electrophoresis systems used were a combination of agarose and polyacrylamide...
متن کاملGlomerular Basement Membrane
The noncollagenous domain hexamer of collagen IV from bovine glomerular basement membrane was further investigated to determine the types of collagen chain from which subunits M2*b and M3 are derived. M2*b was shown to be a shorter form, containing 9 fewer residues, of M2*a which was previously established as the noncollagenous domain of a third chain, a3, of collagen IV (Saus, J., Wieslander, ...
