What do one in five breast cancers have in common? Large amounts of a protein called HER2 (or human epidermal growth factor receptor 2). “Every healthy cell produces a normal amount of HER2, but HER2 is produced 10 to 20 times more in a cancer cell,” said Yehenew Agazie, an associate professor of biochemistry at the West Virginia University School of Medicine.

A team of researchers recently discovered a new aspirin polymorph that’s predicted to dissolve faster than current form I aspirin tablets, which would mean faster pain relief after ingestion. Greater dissolving efficiency also means that each tablet would require less of the compound. Chunhua (Tony) Hu, New York University, will present the painstaking story of aspirin IV alongside its structural definition at the 68th Annual Meeting of the American Crystallographic Association.
Phospholipases are enzymes that cleave the tail group off of phospholipids, which make up cell membranes. These tails, or free fatty acids, can go on to act as signaling molecules. Lysosomal phospholipase A2, or LPA2, is a phospholipase from the macrophages that protect the lung.
People with chronic kidney disease are at unusually high risk of also developing cardiovascular disease; in fact, a patient with non-dialysis kidney disease is more likely to die of heart failure than to develop end-stage kidney failure. However traditional atherosclerosis risk factors contribute less strongly to cardiovascular disease in chronic kidney disease patients than in subjects with intact kidney function.
Researchers at Georgia Institute of Technology have created a material derived from crab shells and tree fibers that has the potential to replace the flexible plastic packaging used to keep food fresh.
Many vaccines become ineffective when exposed to room temperature or heat. This challenge can prevent patients from accessing lifesaving immunizations and increase the risk of global pandemics. During the 68th Annual Meeting of the American Crystallographic Association, Jeremiah Gassensmith, University of Texas at Dallas, will describe his lab’s work developing metal-organic framework vaccines. This new biocompatible polymer framework “freezes” proteins inside vaccines. The proteins then dissolve when injected in human skin. This innovation could help health care providers transport and administer vaccines in remote areas with unreliable power.

The clinical trial will evaluate the use of the assay to aid in the differentiation of IBD from irritable bowel syndrome (IBS) when used in conjunction with other diagnostic testing.
Studying the photochemistry has shown that ultraviolet radiation can set off harmful chemical reactions in the human body and, alternatively, can provide “photo-protection” by dispersing extra energy. To better understand the dynamics of these photochemical processes, a group of scientists irradiated the RNA base uracil with ultraviolet light and documented its behavior on a picosecond timescale. They discuss their work this week in The Journal of Chemical Physics.

A biochemical engineer at Missouri University of Science and Technology has patented a method of removing these harmful elements from water and also from pharmaceutical formulations.Her goal: improve drug safety and increase access to clean drinking water in the developing world.
A stable cell line of Wolbachia-infected fruit fly cells turned out to be an invaluable tool for researchers seeking new drugs to treat river blindness and related diseases. That's because the parasitic worms that cause these diseases are actually dependent on Wolbachia bacteria living within their cells. Kill the Wolbachia, and the worms die.
A review of more than 200 studies reveals that olfactory receptors—proteins that bind to odors that aid the sense of smell—perform a wide range of mostly unknown functions outside the nose. The function of extra-nasal olfactory receptors has the potential to be used in the diagnosis and treatment of health conditions such as cancer.

The compound urea is currently the most popular nitrogen soil fertilizer. It’s a way to get plants the nitrogen they need to grow. There’s just one problem with urease: it works too well! New research suggests farmers may have a choice in how they slow the release of nitrogen, depending on their soil’s acidity.
Researchers from the University of Illinois at Chicago are the first to describe why CRISPR gene editing sometimes fails to work, and how the process can be made to be much more efficient.
Through x-ray crystallography and kinase-inhibitor specificity profiling, University of California San Diego School of Medicine researchers, in collaboration with researchers at Peking University and Zhejiang University, reveal that curcumin, a natural occurring chemical compound found in the spice turmeric, binds to the kinase enzyme dual-specificity tyrosine-regulated kinase 2 (DYRK2) at the atomic level. This previously unreported biochemical interaction of curcumin leads to inhibition of DYRK2 that impairs cell proliferation and reduces cancer burden.
How do insects survive harsh northern winters? Unlike mammals, they don’t have thick coats of fur to keep warm. But they do have antifreeze. Antifreeze proteins (AFPs) prevent ice from forming and spreading inside their bodies. The existence of these AFPs has been known for decades, but the mechanisms governing this unique survival technique have proven difficult to determine.
