objective: oxidative stress that damages proteins result in aging and age related diseases. the aim of this study is to determine the effect of tocotrienol rich fraction (trf) on the expression of proteins in oxidative stress-induced caenohabditis elegans (c.elegans) which has homologous genes to humans. methods: the worms were treated with trf prior to, after and continuously in separate group...

Proteinase A and proteinase B, two vacuolar enzymes in Saccharomyces cerevisiae, are synthesized as larger precursors with apparent molecular weights of approximately 52,000 and 42,000, respectively. These precursor molecules are processed to their mature forms of 42,000 molecular weight for proteinase A and 33,000 molecular weight for proteinase B. In the presence of tunicamycin, an inhibitor ...

An important goal for the investigation of the proliferation of mammalian cells is to establish a fully defined condition for culturing them in vitro. Here, we report establishment of a fully defined culture condition that supports the primary culture of normal c-kit+IL-7 receptor (IL-7R)+ B precursor cells without the aid of stromal cell lines. This defined culture condition contains IL-7, the...
