Drosophila insulin-like peptides (dILPs) regulate part of the signaling pathway that helps keep organs growing in proportion during development.
A rare peek inside the subterranean home of the naked mole-rat
Telomeres are repetitive, noncoding sequences that cap the ends of linear chromosomes. They consist of hexameric nucleotide sequences (TTAGGG in humans) repeated hundreds to thousands of times. Telomeres protect the protein-coding sequences of DNA on
A transition-state mimic has the power to bind an enzyme at its tipping point as strongly as any available inhibitor and more strongly than most, preventing enzymatic activity. In order to replicate the structure of an enzyme’s transition state, whic
Vitamin D has a variety of actions in the body. It binds to the vitamin D receptor (VDR), which then binds to the retinoid X receptor (RXR) and activates the expression of numerous genes. Through this mechanism, vitamin D promotes calcium absorption
Normal pancreatic function depends on the precise flow of calcium within and into the acinar cells of the organ. When food is eaten, low concentrations of the pancreas-stimulating hormone cholecystokinin or of the neurotransmitter acetylcholine cause
In fewer than 15 years, nanomedicine has gone from fantasy to reality.
Looking for a more realistic way to study memory, we turned to place cells—a network of cells that record a rat’s memory of an environment. Each place cell would fire only when the rat was in one particular location in space, creating a map as the
Long-term potentiation (LTP), discovered in the 1970s, was later shown to be the molecular basis of memory. Since many diseases of aging affect memory, could memory formation and storage be altered by the same mechanisms in normal aging and diseased
