Regulation of cathepsin B
Most malignant tumors show increased transcriptional activation of cathepsin B. More than a decade ago, Qian, et al. identified that increased expression of cathepsin B in B16a melanoma cells is due to a specific increase in the amount or activity of a transcriptional activator of the cathepsin B gene [50]. Later, the research group of Sloane, et al., found that more than one promoter could dir...
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 کاملExpression of lysosomal cathepsin B during calf myoblast-myotube differentiation. Characterization of a cDNA encoding bovine cathepsin B.
Expression of lysosomal cysteine proteinases was studied during fetal calf myoblast-myotube differentiation. Activities of cathepsin B and L, but not cathepsin H, increase during bovine myogenic differentiation. In fetal muscle, cathepsin B and L activities are 2-4-fold orders of magnitude lower than in cultured myoblasts. Active-site titrations of cathepsin B with E-64 nevertheless reveal simi...
متن کاملCathepsin B Gene Disruption Induced Leishmania donovani Proteome Remodeling Implies Cathepsin B Role in Secretome Regulation
Leishmania cysteine proteases are potential vaccine candidates and drug targets. To study the role of cathepsin B cysteine protease, we have generated and characterized cathepsin B null mutant L. donovani parasites. L. donovani cathepsin B null mutants grow normally in culture, but they show significantly attenuated virulence inside macrophages. Quantitative proteome profiling of wild type and ...
متن کاملCrystallization of recombinant rat cathepsin B.
A glycosylation-minus mutant of rat cathepsin B expressed in yeast has been purified and crystallized. X-ray diffraction data have been collected and molecular replacement for solving the structure is in progress. The space group for the recombinant rat cathepsin B was determined to be P2(1) with unit cell dimensions alpha = 62.2 A, b = 90.19 A, c = 47.07 A, and beta = 97.43 degrees. A unit cel...
