BUSM researcher finds link between brain signaling and renal function

05.06.2012
Boston University School of Medicine (BUSM) researchers recently uncovered a brain signaling pathway responsible for regulating the renal excretion of sodium. The findings appear in the Journal of the Federation of American Societies for Experimental Biology.

Hypertension, or chronic high blood pressure, affects one-third of adults, significantly increasing cardiovascular risk and mortality. Approximately 50 percent of hypertensive patients are salt-sensitive and exhibit an increase in blood pressure following salt-intake.

According to the researchers, little is known about the mechanisms acting in the brain to control the removal of dietary salt from the body through the kidneys. "Our data shows that changes in dietary sodium intake evoked natural site-specific changes in brain hypothalamic paraventricular nucleus (PVN) Gái2 protein levels," said Senior Author Richard Wainford, PhD, assistant professor of pharmacology and experimental therapeutics.

Wainford and his team explored the role of Gái2 signal transduction proteins in the brain pathways activated to regulate salt and water excretion and subsequently blood pressure. They identified a previously unknown role of PVN Gái2-subunit proteins as a central mechanism mediating the suppression of renal sympathetic nerve traffic to the kidneys and the renal excretion of sodium.

These data provide a target for new therapies that may improve cardiovascular and renal excretory function. This may help treat multiple disease states, such as salt-sensitive hypertension and congestive heart failure caused by elevated sodium intake.

This research was funded by the American Heart Association (AHA) and the National Heart Lung and Blood Institute (NHLBI).

Im Focus: Neutron star merger directly observed for the first time

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event

On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...

Im Focus: Breaking: the first light from two neutron stars merging

Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.

Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....

Im Focus: Smart sensors for efficient processes

Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).

When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...

Im Focus: Cold molecules on collision course

Using a new cooling technique MPQ scientists succeed at observing collisions in a dense beam of cold and slow dipolar molecules.

How do chemical reactions proceed at extremely low temperatures? The answer requires the investigation of molecular samples that are cold, dense, and slow at...

Im Focus: Shrinking the proton again!

Scientists from the Max Planck Institute of Quantum Optics, using high precision laser spectroscopy of atomic hydrogen, confirm the surprisingly small value of the proton radius determined from muonic hydrogen.

It was one of the breakthroughs of the year 2010: Laser spectroscopy of muonic hydrogen resulted in a value for the proton charge radius that was significantly...
