One of the major stress factors during space and high-altitude flight is the oxidative damage caused by the release of reactive oxygen intermediates (ROIs) in human tissues. ROIs are released in response to several stress factors including radiation in space. Since ROIs contribute to several pathological conditions, there has been a great interest in(More)
Human Rec2/Rad51L1 is a member of the Rad51 family of proteins. Although recombinase activity, typical of this family, could not be established, its overexpression in mammalian cells has been shown to cause a delay in G1. Moreover, since hsRec2/Rad51L1 has been found to be induced by both ionizing and UV irradiation, it is likely that hsRec2/Rad51L1 is(More)
To support the study of the effects of microgravity on biological systems, our group is developing and testing methods that allow the cultivation of C. elegans and S. cerevisiae in microgravity. Our aim is to develop the experimental means by which investigators may conduct peer reviewed biological experiments with C. elegans or S. cerevisiae in(More)
