Cathepsin B, the lysosomal thiol proteinase of calf liver.
Cathepsin B from calf liver was obtained by a method involving preparation of a lysosomal-mitochondrial pellet and treatment of this pellet with acetone. The material was extracted with an acid buffer, pH4.0, and then precipitated from the extract with acetone. The precipitate was dissolved in phosphate buffer, pH7.4, and subjected to gel filtration on Sephadex G-200 and G-100. The cathepsin B ...
متن کاملUbiquitin-protein conjugates accumulate in the lysosomal system of fibroblasts treated with cysteine proteinase inhibitors.
Mouse fibroblasts (3T3-L1 cells) accumulate detergent- and salt-insoluble aggregates of proteins conjugated to ubiquitin when incubated in the presence of inhibitors of lysosomal cysteine cathepsins, including E-64. These ubiquitin-protein conjugates co-fractionate with lysosomes on density gradients and are found in multivesicular dense bodies which by electron microscopy appear to be engaged ...
متن کاملIsolation of a cDNA clone for the human lysosomal proteinase cathepsin B.
The cysteine proteinase cathepsin B is one member of the lysosomal acid hydrolases. Based on the peptide sequence of rat liver cathepsin B, an oligonucleotide mixture containing 128 different 17-mers was synthesized and used as a probe to screen adult and fetal human liver cDNA libraries. A recombinant clone with a 1540-nucleotide insert was identified from the fetal library, and DNA sequence a...
متن کاملInvolvement of Lysosomal Labilisation and Lysosomal/mitochondrial Cross-Talk in Diclofenac Induced Hepatotoxicity
In this research, we investigated the cytotoxic mechanisms of one of the widely used pharmaceuticals that are regularly associated with the adverse effects on the liver, sometimes leading to acute liver failure, diclofenac. Diclofenac liver cytotoxicity was associated with reactive oxygen species (ROS) formation and lipid peroxidation which were inhibited by antioxidants and ROS scavengers, fer...
