Upstream and downstream of mTOR.
The evolutionarily conserved checkpoint protein kinase, TOR (target of rapamycin), has emerged as a major effector of cell growth and proliferation via the regulation of protein synthesis. Work in the last decade clearly demonstrates that TOR controls protein synthesis through a stunning number of downstream targets. Some of the targets are phosphorylated directly by TOR, but many are phosphory...
متن کاملMaking mesoderm-upstream and downstream of Xbra 219 Making mesoderm–upstream and downstream of Xbra
The mesoderm of the amphibian embryo is formed through an inductive interaction in which cells of the vegetal hemisphere of the embryo act on overlying equatorial cells. My laboratory is studying the Brachyury gene, which plays a key role in this interaction, being both necessary and sufficient for normal mesoderm formation. In this article I describe our attempts to understand how Xenopus Brac...
متن کاملTransfer of nitric oxide by blood from upstream to downstream resistance vessels causes microvascular dilation.
The discovery that hemoglobin, albumin, and glutathione carry and release nitric oxide (NO) may have consequences for movement of NO by blood within microvessels. We hypothesize that NO in plasma or bound to proteins likely survives to downstream locations. To confirm this hypothesis, there must be a finite NO concentration ([NO]) in arteriolar blood, and upstream resistance vessels must be abl...

متن کاملUpstream versus Downstream Implementation of Climate Policy
This chapter examines the tradeoffs of regulating upstream (e.g., coal, natural gas, and refined petroleum product producers) versus regulating downstream (e.g., direct sources of greenhouse gases (GHG)). In general, regulating at the source provides polluters with incentives to choose among more opportunities to abate pollution. This chapter develops a simple theoretical model that shows why t...
