Dividing stem cells can give rise to two types of daughter cells; self-renewing cells that have virtually the same properties as the parent cell, and differentiating cells that will eventually form part of a tissue. The Caenorhabditis elegans germ line serves as a model to study how the balance between these two types of daughter cells is maintained. A(More)
Glycerol-3-phosphate acyltransferase (GPAT) catalyzes the initial step in the synthesis of all glycerolipids. It is the committed and rate-limiting step and is redundant in Saccharomyces cerevisiae, mammals, and plants. GPAT controls the formation of lipid intermediates that serve not only as precursors of more-complex lipids but also as intracellular(More)
Ascorbate (reduced vitamin C) is required for bone formation. We have shown previously that both the osteoblast-like cell line ROS 17/2.8 and primary cultures of rat calvarial cells possess a saturable, Na(+)-dependent uptake system for L-ascorbate (J Membr Biol 111:83-91, 1989). The purpose of the present study was to investigate the specificity of this(More)
