Molecular thermometers on skin cells detect heat and camphor

... great need for new therapeutics. Indeed, several compounds that are currently under investigation for alleviating chronic pain target the action of a protein called TRPV1 (VR1), which is similar to TRPV3. Molecular Thermometers TRPV3 and TRPV1 are both proteins that belong to a class of molecules known as ...

To Stop Evolution: New Way Of Fighting Antibiotic Resistance Demonstrated By Scripps Scientists

...halted in its tracks by subjecting the bacteria to compounds that block LexA. Interfering with this protein ren...lution of resistance is under the control of LexA, compounds that block the protein might prolong the potency of existing antibiotics. Evolution -- Its not Like...

Newly Discovered 'Branding' Process Helps Immune System Cells Pick Their Fights

...oducts, they start putting out chemically unstable compounds such as nitric oxide and superoxide. Together, these compounds generate peroynitrate, a highly potent chemical that modifies many proteins. Unanue's group showed ...

Prescription Drug Patches Gaining Ground, Tackling New Therapies

...e capable of delivering sustained dosing of active compounds for several days in a smaller package. “The number of drug therapies being developed in patch form is expanding,?explains George Perros, Greystone Managing Director. “At the same time, improvements in patch esthetics and the success of existing presc...

Remote control flies? Fly behavior controlled by laser light

...a and Miesenböck caged the ATP with other chemical compounds that could be removed by the laser light. Miesenböck says one of the most difficult parts of the experiment was deciding which particular nerve cells to target with the remote control system. "To ascertain that the system actually worked, it wasn't ...

A hope for oil spill bioremediation

...al populations able to degrade polycyclic aromatic compounds such as phenanthrene or naphthalene, especially in those sites that had recently been restored after an important contamination episode. Authors concluded that, probably due to the contamination record of the past in that coast, indigenous population...

Computational Tool Predicts How Drugs Work In Cells, Advancing Efforts To Design Better Medicines

The ability to select and develop compounds that act on specific cellular targets has just gai...esses. Using this tool, drug developers can design compounds that will act on only desired gene and protein targets, eliciting therapeutic responses free of unwa...

Major new UNC-based drinking water study suggests pregnancy fears may be overstated

...nalyzed the data to see what effects the byproduct compounds might have had on pregnancy loss (miscarriage). T...itz said. The new work did suggest that brominated compounds and total organic halides at normal-range levels in purified drinking water might modestly increase ...

Natural tumor suppressor in body discovered by UCSD medical researchers

...professor of pharmacology. "Currently there are no compounds identified to directly stop Akt from causing cancer growth, once Akt signaling has been initiated." Scientists have known that Akt is critical in regulating cell growth and death, and that it is linked to some of the most common human cancers. Altho...

Enzyme's newly discovered role may make it target for arthritis treatment

...ement of integrins, an important group of adhesion compounds on the surface of neutrophils. "The way these integrins rearrange and cluster on the cell surface can send a signal back into the cell that modifies the cell's behavior, allowing it to do things like secrete inflammatory factors," Pham explains. "Th...
