Non-canonical functions of the tuberous sclerosis complex-Rheb signalling axis
The protein products of the tuberous sclerosis complex (TSC) genes, TSC1 and TSC2, form a complex, which inhibits the small G-protein, Ras homolog enriched in brain (Rheb). The vast majority of research regarding these proteins has focused on mammalian Target of Rapamycin (mTOR), a target of Rheb. Here, we propose that there are clinically relevant functions and targets of TSC1, TSC2 and Rheb, ...
متن کاملPaused RNA Polymerase II as a Developmental Checkpoint
The textbook view of gene activation is that the rate-limiting step is the interaction of RNA polymerase II (Pol II) with the gene's promoter. However, studies in a variety of systems, including human embryonic stem cells and the early Drosophila embryo, have begun to challenge this view. There is increasing evidence that differential gene expression often depends on the regulation of transcrip...
متن کاملControl of TSC2-Rheb signaling axis by arginine regulates mTORC1 activity.
The mammalian target of rapamycin complex 1 (mTORC1) is the key signaling hub that regulates cellular protein homeostasis, growth, and proliferation in health and disease. As a prerequisite for activation of mTORC1 by hormones and mitogens, there first has to be an available pool of intracellular amino acids. Arginine, an amino acid essential during mammalian embryogenesis and early development...
متن کاملNitrogen Regulates AMPK to Control TORC1 Signaling
BACKGROUND Cell growth and cell-cycle progression are tightly coordinated to enable cells to adjust their size (timing of division) to the demands of proliferation in varying nutritional environments. In fission yeast, nitrogen stress results in sustained proliferation at a reduced size. RESULTS Here, we show that cells can sense nitrogen stress to reduce target of rapamycin complex-1 (TORC1)...
متن کاملCopper signaling axis as a target for prostate cancer therapeutics.
Previously published reports indicate that serum copper levels are elevated in patients with prostate cancer and that increased copper uptake can be used as a means to image prostate tumors. It is unclear, however, to what extent copper is required for prostate cancer cell function as we observed only modest effects of chelation strategies on the growth of these cells in vitro. With the goal of...
