PROTEIN ABSORPTION BY RENAL CELLS

Protein Absorption by Renal Cells

In vitro digestion by intact lysosomes was first demonstrated by Mego and McQueen (1965 a, 1967) using mouse liver preparations. More recently, similar observations have been made with other organisms and tissues, for instance with preparations of rat yolk sac (Williams et al, 1972) and frog and toad liver and kidney (Mego, 1971) . The mechanism of lysosomal protein digestion has been examined ...

Lytic Activities in Renal Protein Absorption Droplets

The digestive cycle following reabsorption of hemoglobin by cells of the proximal convoluted tubules in mouse kidney and the uptake of ferritin by glomerular mesangial cells in the kidney of normal and nephrotic rats were investigated by electron microscopical histochemical procedures. Mouse kidneys, sampled at closely spaced time points between 1 to 48 hours after intraperitoneal injection of ...

Renal tubular protein absorption in the rat.

Radioiodinated protein solutions, 20 nl in volume, were injected into surface proximal and distal convoluted tubules of the rat kidney. The unabsorbed fraction was collected in ureteral urine, and the percentage recovered was expressed as a function of the injection site. Recovery increased progressively from more distal sites of injection indicating absorption along the proximal tubule of huma...

Iron Absorption by Enzymically Isolated Leaf Cells'

The rate of Fe absorption by cells enzymically isolated from tobacco leaves is corre'ated with the age of the leaves from which the cells are derived4 The cells obtained from younger leaves absorb Fe more rapidly than those from older ones. Ca inhibits Fe and Mn absorption. Fe and Mn are mutually antagonitic in their absorption by leaf cells. Ca enhances the inhibition of Mn absorption by Fe, b...
