Cathepsin L and cathepsin B mediate reovirus disassembly in murine fibroblast cells.
After attachment to receptors, reovirus virions are internalized by endocytosis and exposed to acid-dependent proteases that catalyze viral disassembly. Previous studies using the cysteine protease inhibitor E64 and a mutant cell line that does not support reovirus disassembly suggest a requirement for specific endocytic proteases in reovirus entry. This study identifies the endocytic proteases...
متن کاملMutant cells selected during persistent reovirus infection do not express mature cathepsin L and do not support reovirus disassembly.
Persistent reovirus infections of murine L929 cells select cellular mutations that inhibit viral disassembly within the endocytic pathway. Mutant cells support reovirus growth when infection is initiated with infectious subvirion particles (ISVPs), which are intermediates in reovirus disassembly formed following proteolysis of viral outer-capsid proteins. However, mutant cells do not support gr...
متن کاملCathepsin B trafficking in thyroid carcinoma cells
BACKGROUND The cysteine peptidase cathepsin B is important in thyroid physiology by being involved in prohormone processing initiated in the follicle lumen and completed in endo-lysosomal compartments. However, cathepsin B has also been localized to the extrafollicular space in thyroid cancer tissue, and is therefore suggested to promote invasiveness and metastasis in thyroid carcinomas through...
متن کاملEffects of Endurance Training on the Expression of Cathepsin B (CTSB) and Cathepsin L (CTSL) genes in the Adipose Tissue of Mice with a High-Fat Diet
Introduction: In high-fat diet-induced obesity, the levels of cathepsin L (CTSL) and cathepsin B (CTSB) increase in adipocytes, resulting in insulin resistance in the adipose tissue. In this study, the preventive effect of endurance training on the gene expression of CTSL and CTSB was investigated in the adipose tissue of mice with a high-fat diet. Materials and Methods: Twenty-one male mice (a...
متن کاملThe Cathepsin B-Selective Inhibitors CA-074 and CA-074Me Inactivate Cathepsin L Under Reducing Conditions
The inhibitor CA-074 and its membrane-permeable derivative CA-074Me have been widely employed to study the biological function of cathepsin B. These compounds have been described as selective inactivators of cathepsin B with barely detectable action on other cathepsins. However, in this study it is demonstrated that CA-074 and CA-074Me also inactivate cathepsin L in the presence of the thiol re...
