Telomere length homeostasis responds to changes in intracellular dNTP pools.
Telomeres, the ends of linear eukaryotic chromosomes, shorten due to incomplete DNA replication and nucleolytic degradation. Cells counteract this shortening by employing a specialized reverse transcriptase called telomerase, which uses deoxyribonucleoside triphosphates (dNTPs) to extend telomeres. Intracellular dNTP levels are tightly regulated, and perturbation of these levels is known to aff...
متن کاملRecurrent stroke due to a novel voltage sensor mutation in Cav2.1 responds to verapamil.
BACKGROUND AND PURPOSE Familial hemiplegic migraine is characterized by recurrent migraine, hemiparesis, and ataxia. Causes may be mutations in calcium and sodium channels or in a subunit of the Na/K-ATPse. Migraine treatment with calcium channel blockers was only successful in some patients. Summary of Case- We describe a 6-year-old girl with recurrent ischemic strokes after minor head trauma ...

Background and Purpose—Familial hemiplegic migraine is characterized by recurrent migraine, hemiparesis, and ataxia. Causes may be mutations in calcium and sodium channels or in a subunit of the Na/K-ATPse. Migraine treatment with calcium channel blockers was only successful in some patients. Summary of Case—We describe a 6-year-old girl with recurrent ischemic strokes after minor head trauma a...
متن کاملPower changes how the brain responds to others.
Power dynamics are a ubiquitous feature of human social life, yet little is known about how power is implemented in the brain. Motor resonance is the activation of similar brain networks when acting and when watching someone else act, and is thought to be implemented, in part, by the human mirror system. We investigated the effects of power on motor resonance during an action observation task. ...
متن کاملStructural Mechanisms of Voltage Sensing in G Protein-Coupled Receptors
G-protein-coupled receptors (GPCRs) form the largest superfamily of membrane proteins and one-third of all drug targets in humans. A number of recent studies have reported evidence for substantial voltage regulation of GPCRs. However, the structural basis of GPCR voltage sensing has remained enigmatic. Here, we present atomistic simulations on the δ-opioid and M2 muscarinic receptors, which sug...
