Research may puzzle out HIV transmission by sexual contact

The virus that causes AIDS may undergo changes in the genital tract that make HIV-1 in semen different than what it is in the blood, according to a study led by researchers from the University of North Carolina at Chapel Hill.

Deficiencies in DNA loop formation can cause multiple diseases: Research

The genes that are responsible for maintaining each cell type form DNA loops that link control elements for these genes. This surprising genome structure is generated and reinforced by two essential protein complexes that bridge the loops and contribute to proper gene regulation.

New clues to molecular action of Alzheimer's drug memantine

Alzheimer's disease destroys brain cells and their connections (called synapses), causing memory loss and other cognitive problems that disrupt work, hobbies and daily life. Symptoms can be alleviated, in part, by the drug memantine (marketed in the United States as Namenda), which is currently FDA-approved to treat moderate-to-severe Alzheimer's disease and was, in part, developed by Stuart A. Lipton, M.D., Ph.D., Director of the Del E. Web Center for Neuroscience, Aging and Stem Cell Research at Sanford-Burnham Medical Research Institute (Sanford-Burnham).

Cluster-coated implant strengthens attachment of joint-replacement implant with bone

Researchers have developed an improved coating technique that could strengthen the connection between titanium joint-replacement implants and a patients' own bone. The stronger connection created by manipulating signals the body's own cells use to encourage growth could allow the implants to last longer.

Breast cancer accomplice discovered

Scientists have discovered an accomplice in breast cancer - a master control switch with the power to set off a cascade of reactions orchestrated by a cancer-causing gene (or oncogene) named Wnt1. This executive molecule and its modus operandi are reported in back-to-back papers featured on the cover of the August 15 issue of Cancer Research.

Rice receives Defense Threat Reduction Agency grant to develop genomic test for cultivated pathogens

Researchers at Rice University have won federal support to develop a genomic test that can quickly determine whether a disease outbreak is caused by a natural pathogen or one that was grown in a lab by terrorists.

Study finds abnormal expression of miRNAs can contribute to human diseases

Researchers at Tufts University School of Medicine and Tufts Medical Center have identified an RNA sequence that promotes increased numbers of specific microRNAs (miRNAs), molecules that regulate cell growth, development, and stress response. The discovery helps researchers understand the links between miRNA expression and disease, including heart disease and cancer. The findings are published in the August 13 issue of Molecular Cell.

High exposure to estrogens may cause gall bladder cancer: Research

A very aggressive disease with a poor prognosis, gallbladder cancer may be connected to higher exposure to estrogens, according to a group of researchers at the University of Houston (UH). Dr. Jan--ke Gustafsson, Robert A. Welch Professor in UH's biology and biochemistry department, described his team's findings in a paper titled "Estrogen-dependent gallbladder carcinogenesis in LXRβ-/- female mice" appearing in a recent issue of the journal Proceedings of the National Academy of Sciences, one of the world's most-cited multidisciplinary scientific serials.

Researchers find link between chronic inflammation and cancer

Virginia Commonwealth University Massey Cancer Center researchers have uncovered a new link between chronic inflammation and cancer. Although cancers do not always cause inflammation, chronic inflammation is known to help tumor cells grow.

Study reveals how galectin-3 carbohydrate-binding protein promotes angiogenesis

A new study describes how a carbohydrate-binding protein, galectin-3, promotes angiogenesis, the growth of new blood vessels. Targeting the protein, scientists identified two approaches that significantly reduced angiogenesis in mice. These discoveries, published online August 16 in The Journal of Experimental Medicine, may lead to novel treatments for diseases caused by excessive angiogenesis, including age-related macular degeneration, cancer, and diabetes.

Scientists find therapeutic potential of stem cells for acute lung injury

Researchers are reporting this week new study results they say provide further evidence of the therapeutic potential of stem cells derived from bone marrow for patients suffering from acute lung injury, one of the most common causes of respiratory failure in intensive care units.

Scientists develop new metabolite analysis technique for accurate ovarian cancer detection

Scientists at the Georgia Institute of Technology have attained very promising results on their initial investigations of a new test for ovarian cancer. Using a new technique involving mass spectrometry of a single drop of blood serum, the test correctly identified women with ovarian cancer in 100 percent of the patients tested. The results can be found online in the journal Cancer Epidemiology, Biomarkers, & Prevention Research.

Silence Therapeutics receives patent for RNA silencing method

Silence Therapeutics plc announces the issuance of United States patent 7,772,203, titled "Methods and Compositions for Controlling Efficacy of RNA Silencing," by the United States Patent and Trademark Office (USPTO). The issued patent generally claims methods of enhancing RNA silencing with a double stranded RNA interference (RNAi) agent. The patent's RNA silencing method claims include coverage for the administering of a pharmaceutical composition containing short interfering RNA (siRNA), micro RNA (miRNA), pre-miRNA or short hairpin (shRNA) molecules. Silence believes the proprietary structural modification techniques covered in this patent will play a key role in increasing the potential therapeutic efficacy of RNAi therapeutics.

Common soluble proteins become insoluble and form aggregates while aging: Study

In neurodegenerative diseases, clumps of insoluble proteins appear in patients' brains. These aggregates contain proteins that are unique to each disease, such as amyloid beta in Alzheimer's disease, but they are intertwined with small amounts of many other insoluble proteins that are normally present in a soluble form in healthy young individuals. For years, these other proteins were thought to be accidental inclusions in the aggregates, much as a sea turtle might be caught in a net of fish.Now, in a surprising new finding, researchers at the University of California, San Francisco, report that many of the proteins present as minor components of disease aggregates actually clump together as a normal part of aging in healthy individuals.

Spinal muscular atrophy may lead to cardiac dysfunction: Study

Along with skeletal muscles, it may be important to monitor heart function in patients with spinal muscular atrophy (SMA). These are the findings from a study conducted by Nationwide Children's Hospital and published online ahead of print in Human Molecular Genetics. This is the first study to report cardiac dysfunction in mouse models of SMA.
