Improved-resolution views of a zinc transporter protein deciphered

New, improved-resolution views of a zinc transporter protein deciphered at the U.S. Department of Energy's Brookhaven National Laboratory provide not just a structure but also a suggested mechanism for how cells sense and regulate zinc, an element that is essential for life, but which must be kept at a steady state to avoid problems like seizures, diabetes, and possibly Alzheimer's disease.

New method for detecting oxidative stress in tumor cells

The growth of cancerous tumors is fueled, at least in part, by the buildup of free radicals---highly reactive oxygen-containing molecules.

Cellular mechanosensory system may yield new insights for cancer therapy

Every moment, millions of a body's cells flawlessly divvy up their genes and pinch perfectly in half to form two identical progeny for the replenishment of tissues and organs - even as they collide, get stuck, and squeeze through infinitesimally small spaces that distort their shapes.

Lead exposure may result in cardiovascular mortality

Growing evidence shows that exposure to lead in the environment is associated with cardiovascular disease, including increased risk of hypertension. However, those studies have looked at lead concentrations in blood, not bone lead, a better indicator of cumulative lead exposure over time.

Iterative in situ click chemistry creates antibody-like protein-capture agents

Chemists at the California Institute of Technology (Caltech) and The Scripps Research Institute (SRI) have developed an innovative technique to create cheap but highly stable chemicals that have the potential to take the place of the antibodies used in many standard medical diagnostic tests. James R. Heath, Ph.D., principal investigator of the Nanosystems Biology Cancer Center at Caltech, one of eight Centers of Cancer Nanotechnology Excellence, and K. Barry Sharpless, Ph.D., SRI, and their colleagues describe the new technique in the journal Angewandte Chemie International Edition.

Specific targeting of brain tumors with an optical/magnetic resonance imaging nanoprobe across the blood-brain barrier

Earlier this year, researchers at the University of Washington reported that they had developed a toxin-nanoparticle combination that inhibits brain cancer invasion when added to tumor cells growing in culture.

Aptamer nanoflares for molecular detection in living cells

By combining a gold nanoparticle with a unique family of nucleic acids, researchers at Northwestern University have created a new type of intracellular reporting system that with a flash of light reveals the presence and quantity of a wide variety of biologically important molecules. These so-called nanoflares could provide cancer biologists with a highly sensitive method of tracking complex biochemical processes in real time without interfering with those processes.

New Promega GoTaq qPCR Master Mix features increased reliability

Now real-time PCR methods can detect even smaller changes and rare events with the new Promega GoTaq qPCR Master Mix. The new GoTaq qPCR Master Mix frequently delivers earlier cycle thresholds than SYBR Green I. The advanced functionality gives scientists both increased reliability and reproducibility compared to the performance of existing real-time reagent systems.

New molecular sensor could identify zinc-related diseases

Scientists have developed a new molecular sensor that can reveal the amount of zinc in cells, which could tell us more about a number of diseases, including type 2 diabetes. The research, published today in Nature Methods, opens the door to the hidden world of zinc biology by giving scientists an accurate way of measuring the concentration of zinc and its location in cells for the first time.
