Study of plant hormone could have far-reaching implications for cell biology and disease research A recent Van Andel Research Institute (VARI) study published in the journal Science investigating the molecular structure and function of an essential plant hormone could profoundly change our understanding of a key cell process, and might ultimately lead to the development of new drugs for a variety of diseases. The study builds on earlier work by the same team of investigators at VARI...

Luteolin is a flavonoid commonly found in fruit and vegetables. This compound has been shown in laboratory conditions to have anti-inflammatory, anti-oxidant and anti-cancer properties but results from epidemiological studies have been less certain. New research published in BioMed Central's open access journal BMC Gastroenterology shows that luteolin is able to inhibit the activity of cell signaling pathways (IGF and PI3K) important for the growth of cancer in colon cancer cells. Colon...

A receptor found on blood platelets whose importance as a potential pharmaceutical target has long been questioned may in fact be fruitful in drug testing, according to new research from Michigan State University chemists. A team led by Dana Spence of MSU's Department of Chemistry has revealed a way to isolate and test the receptor known as P2X1. By creating a new, simple method to study it after blood is drawn, the team has unlocked a potential new drug target for many diseases that...

New Findings Could Influence Design of Future Diabetes Treatments Using a blend of technologies, scientists from the Florida campus of The Scripps Research Institute have painted a new picture of how biochemical information can be transmitted through the modification of a protein. Previously, scientists believed that during the pairing of proteins and their binding partners (“ligands”), proteins modified their shape while ligands remained stable. The new study shows this...

Brain cancer is hard to treat: it´s not only strong enough to resist most chemotherapies, but also nimble enough to migrate away from radiation or surgery to regrow elsewhere. New research at the University of Colorado Cancer Center shows how to stop both. Specifically, cells signal themselves to survive, grow, reproduce, and migrate. Two years ago, researchers at the CU Cancer Center showed that turning off a family of signals made brain cancer cells less robust — it...

Control of a “blind” neuroreceptor with an optical switch When nerve cells communicate with one another, specialized receptor molecules on their surfaces play a central role in relaying signals between them. A collaborative venture involving teams of chemists based at Ludwig-Maximilians-Universität (LMU) in Munich and the University of California in Berkeley has now succeeded in converting an intrinsically “blind” receptor molecule into a...


Word of the Day
call-note
  • The call or cry of a bird or other animal to its mate or its young.
'Call-note' is newer than 'bird-call,' which originally referred to 'an instrument for imitating the note of birds' but now also refers to 'the song or cry of a bird.'
