UPC develops new system for electroporation of cell cultures

Researchers from the Polytechnic University of Catalonia have developed a technique that improves and cuts the cost of a technique called electroporation, which involves opening pores in cell membranes using an electric field to introduce substances like drugs and DNA. Current methods are aggressive and expensive whereas the new system manages to apply low voltage electroporation with a small printed circuit board, which costs less than a Euro per unit and does not damage cells.

APOBEC3B enzyme plays a key role in breast cancer

Researchers at the University of Minnesota have uncovered a human enzyme responsible for causing DNA mutations found in the majority of breast cancers. The discovery of this enzyme - called APOBEC3B - may change the way breast cancer is diagnosed and treated.

Tat-beclin 1 shows promise against infections, neurodegenerative disorders and cancer

UT Southwestern Medical Center scientists have synthesized a peptide that shows potential for pharmaceutical development into agents for treating infections, neurodegenerative disorders, and cancer through an ability to induce a cell-recycling process called autophagy.

Single gene therapy session can cure diabetes

Researchers from the Universitat Aut-noma de Barcelona (UAB), led by F-tima Bosch, have shown for the first time that it is possible to cure diabetes in large animals with a single session of gene therapy. As published this week in Diabetes, the principal journal for research on the disease, after a single gene therapy session, the dogs recover their health and no longer show symptoms of the disease.

Studies to identify molecular causes and preventive and therapeutic strategies for Parkinson's

On the fourth floor of Wichita State University's McKinley Hall, biochemistry professor Kandatege Wimalasena and his group of doctoral and undergraduate students are hard at work researching Parkinson's disease (PD) - the second-most common neurodegenerative disease, affecting 1 to 2 percent of people older than 60.

Oleuropein aglycone reduces inflammation associated with intestinal ischemia and reperfusion

Here's another reason why you should include olive oil in your diet: A new research report published in the Journal of Leukocyte Biology suggests that at least one compound in olive oil significantly reduces intestinal ischemia (restricted blood supply) and the resulting reperfusion injury (tissue damage caused when blood supply returns).

Nitric oxide shuts down brain's repair mechanisms

Nitric oxide, a gaseous molecule produced in the brain, can damage neurons. When the brain produces too much nitric oxide, it contributes to the severity and progression of stroke and neurodegenerative diseases such as Alzheimer's. Researchers at Sanford-Burnham Medical Research Institute recently discovered that nitric oxide not only damages neurons, it also shuts down the brain's repair mechanisms.

PET with 11C-PIB can positively visualize amyloid deposits in the heart

While amyloid imaging may now be most associated with detecting plaques in the brain, it has the potential to change the way cardiac amyloidosis is diagnosed. According to first-of-its-kind research published in the February issue of The Journal of Nuclear Medicine, positron emission tomography (PET) with 11C-PIB can positively visualize amyloid deposits in the heart.

Cells lose ability to defend against transposons as they age

Even in our DNA there is no refuge from rogues that prey on the elderly. Parasitic strands of genetic material called transposable elements - transposons - lurk in our chromosomes, poised to wreak genomic havoc. Cells have evolved ways to defend themselves, but in a new study, Brown University researchers describe how cells lose this ability as they age, possibly resulting in a decline in their function and health.

Investigators use genome analysis to eliminate lifetime drug prescription in two children

Using genome-wide analysis, investigators at the Sainte-Justine University Hospital Research Center and the University of Montreal have potentially eliminated a lifetime drug prescription that two children with a previously unknown type of adrenal insufficiency had been receiving for 14 years.

Two new methods could accelerate development of improved antisense drugs

Powerful antisense drugs that target disease-associated genes to block their expression can be used to treat a broad range of diseases. Though antisense therapy has been proven effective, challenges remain in ensuring that the drugs reach their intended targets.

PKCζ protein plays a critical role in regulating tumor metabolism

Cancer cells need food to survive and grow. They're very good at getting it, too, even when nutrients are scarce. Many scientists have tried killing cancer cells by taking away their favorite food, a sugar called glucose. Unfortunately, this treatment approach not only fails to work, it backfires-glucose-starved tumors actually get more aggressive.

Scientists identify specific p53 pocket that can be targeted by cancer-fighting drugs

UC Irvine biologists, chemists and computer scientists have identified an elusive pocket on the surface of the p53 protein that can be targeted by cancer-fighting drugs. The finding heralds a new treatment approach, as mutant forms of this protein are implicated in nearly 40 percent of diagnosed cases of cancer, which kills more than half a million Americans each year.

Scientists review damage-control in metabolism

In this week's issue of the prestigious journal Nature Chemical Biology, scientists Carole Linster (University of Luxembourg), Emile Van Schaftingen (Louvain University), and Andrew D. Hanson (University of Florida, Gainesville) review an important, but so far neglected, part of metabolism, namely metabolite damage-control.
