Homeostasis in vertebrates is tightly regulated by cell death as well as by cell proliferation. The death of cells during embryogenesis, metamorphosis, endocrine-dependent tissue atrophy, and normal tissue turnover is "programmed cell death", mediated by a process called "apoptosis". Cytotoxic T lymphocytes and natural killer cells kill the target cells by(More)
A halophilic and thermophilic isolate from the sand of Tottori Dune was found to produce a thermostable and halophilic leucine dehydrogenase (EC 1.4.1.9). It was identified to be a new strain of Bacillus licheniformis. The enzyme gene was cloned into Escherichia coli JM109 with a vector plasmid pUC18. The enzyme was purified to homogeneity from the clone(More)

Fas is a cell-surface protein belonging to the tumor necrosis factor (TNF) receptor family, whereas the Fas ligand (FasL) is a member of the TNF family. FasL binds to Fas, which results in target cell apoptosis. A family of cysteine proteases is sequentially activated to proceed the Fas-induced apoptosis, whereas Bcl-2 inhibits the process. FasL is(More)
Having originally researched the activities of the potent hematopeotic stimulator of bone-marrow cells, granulocyte colony stimulating factor, Shigekazu Nagata is better known for his work on apoptosis. Here, one of Japan's most renowned biomedical scientists outlines the path that has taken him full circle: from stimulating cells to grow, to finding out(More)
From a thermophilic bacillus a viologen dependent pyridine nucleotide oxidoreductase has been purified and partially characterized. Its apparent molecular weight is about 120000 consisting of two subunits of equal or very similar molecular weight. Per molecular weight of 120000 the enzyme contains 4 FAD. FMN or labile sulfur could not be detected. The(More)
