background : 5-fluorouracil could lead to a decline in fertility in caenorhabditis elegans. the aim of this study was to describe the mechanisms underlying such an altered fertility phenotype and to illustrate the specific genes and path-ways that are involved in the related phenotypic changes in c. elegans. methods : we isolated total rna from the samples and used a new method called digital g...
Mitochondria have long been known to be critical for cell survival due to their role in energy metabolism. However, not until the mid-1990s did it become evident that mitochondria are also active participants in programmed cell death (PCD). This chapter focuses mainly on the role the mitochondria in mammalian cell death and cancer progression and therapy.
In a number of human cancers, NTN1 upregulation inhibits apoptosis induced by its so-called dependence receptors DCC and UNC5H, thus promoting tumor progression. In other cancers however, the selective inhibition of this dependence receptor death pathway relies on the silencing of pro-apoptotic effector proteins. We show here that a substantial fraction of human breast tumors exhibits simultane...
Along with ionotropic and metabotropic glutamate receptors, the cystine/glutamate antiporter x(c)(-) may play a critical role in CNS pathology. High levels of extracellular glutamate inhibit the import of cystine, resulting in the depletion of glutathione and a form of cell injury called oxidative glutamate toxicity. Here we show that a portion of the cell death associated with NMDA receptor-in...
The following review focuses on our current knowledge as to how the cell death regulatory machinery is activated to mediate irradiation-induced cell death. In particular, we will address recent developments related to the following questions: 1.) Which cell death regulatory genes mediate irradiation-induced cell death? 2.) What is the mechanism of irradiation-induced activation or suppression o...
