New substance can replace nucleoside thymidine in DNA biosynthesis

Interactions of biological macromolecules are the central bases of living systems. Biological macromolecules are synthesized in living cells by linking many small molecules together. Naturally occurring macromolecules include genetic materials (DNA) and proteins. A detailed understanding of the synthesis of these macromolecules in whole animals is a basic requirement for understanding biological systems, and for the development of new therapeutic strategies.

Aethlon Hemopurifier can capture Nef protein exosomes linked with HIV

Aethlon Medical, Inc., the pioneer in developing therapeutic filtration devices to address infectious disease and cancer, announced today that researchers have discovered that the Aethlon Hemopurifier is able to capture particles known as Nef protein exosomes, which contribute to the progression of human immunodeficiency virus (HIV) infection to acquired immunodeficiency syndrome.

Researchers identify interactive pathway that regulates cancer metastasis

Finding ways to counteract or disrupt the invasive nature of cancer cells, called "metastasis," has been a long-term goal of cancer researchers. Now, researchers at Moffitt Cancer Center in Tampa, Fla., have identified an interactive pathway that regulates metastases in some cancers that may be vulnerable to chemical targeting in order to prevent cancer cell proliferation and tumor growth.

People with myotonic muscular dystrophy more likely to develop cancer

People who have the most common type of adult muscular dystrophy also have a higher risk of getting cancer, according to a paper published today in the Journal of the American Medical Association.

Vorinostat in addition to chemotherapy drugs improves remission rates in AML patients

Adding a drug that activates genes to frontline combination therapy for acute myeloid leukemia resulted in an 85 percent remission rate after initial treatment, researchers at The University of Texas MD Anderson Cancer Center reported at the 53rd Annual Meeting of the American Society of Hematology.

New exercise and memory study for Parkinson's disease patients

Researchers from the University of Maryland School of Medicine and the Baltimore VA Medical Center have launched a study of exercise and computerized memory training to see if those activities may help people with Parkinson's disease prevent memory changes. The type of memory that will be examined is known as "executive function;" it allows people to take in information and use it in a new way.

Matrix protein tenascin C regulates astrocyte development

How astrocytes, certain cells of the nervous system, are generated was largely unknown up to now. Bochum's researchers have now investigated what influence the cell environment, known as the extracellular matrix, has on this process.

Scientists identify gene mutation behind Waldenstrom's macroglobulinemia

Scientists at Dana-Farber Cancer Institute have identified a gene mutation that underlies the vast majority of cases of Waldenstrom's macroglobulinemia, a rare form of lymphoma that has eluded all previous efforts to find a genetic cause.

DNA sequencing identifies new altered genes that drive CLL

The most comprehensive search to date of DNA abnormalities in chronic lymphocytic leukemia (CLL) has unearthed several new altered genes that drive this common blood cancer, a finding that could potentially help doctors predict whether an individual patient's disease will progress rapidly or remain indolent for years, say scientists from Dana-Farber Cancer Institute and the Broad Institute.

Brain atrophy is evident in Parkinson's patients with MCI

Atrophy in the hippocampus, the region of the brain known for memory formation and storage, is evident in Parkinson's disease (PD) patients with cognitive impairment, including early decline known as mild cognitive impairment (MCI), according to a study by researchers in the Perelman School of Medicine at the University of Pennsylvania.

Scientists identify A2bAR as possible new therapeutic target against atherosclerosis

Researchers from Boston University School of Medicine (BUSM) have identified for the first time the A2b adenosine receptor (A2bAR) as a possible new therapeutic target against atherosclerosis resulting from a diet high in fat and cholesterol.

Research describes advantages of new vaccine adjuvant

New research from the laboratory of Dr. Elizabeth Leadbetter at the Trudeau Institute may lead to a whole new class of vaccines. Dr. Leadbetter's lab has discovered new properties of a potential vaccine adjuvant that suggest it could be useful for enhancing protection against a number of different infections.

Study demonstrates that bone marrow and PBSC result in similar patient survival

Patients who receive a blood stem cell transplant from a donor outside of their family to treat leukemia and other blood diseases are more likely to have graft failure but less likely to experience graft-versus-host disease if the transplanted blood cells come directly from a donor's bone marrow, rather than from circulating peripheral blood stem cells (PBSCs), according to new research.

Scientists pinpoint protein that allows GBM to invade healthy brain tissue

Scientists have pinpointed a protein that allows brains tumors to invade healthy brain tissue, according to work published this week in the Journal of Experimental Medicine.

Researchers discover how bloodstream malaria infection manipulates immune system

University of Iowa researchers and colleagues have discovered how malaria manipulates the immune system to allow the parasite to persist in the bloodstream. By rescuing this immune system pathway, the research team was able to cure mice of bloodstream malaria infections.

New high-alcohol-seeking mice mimics human consumption patterns

A line of laboratory mice developed by a researcher from the School of Science at Indiana University-Purdue University Indianapolis drinks more alcohol than other animal models and consumes it in a fashion similar to humans: choosing alcohol over other options and binge drinking.

Scientists discover how intestinal tract influences B cells to prevent infection

Researchers at the University of Toronto have found an explanation for how the intestinal tract influences a key component of the immune system to prevent infection, offering a potential clue to the cause of autoimmune disorders like rheumatoid arthritis and multiple sclerosis.

Scientists create antigenic myeloma peptide 'cocktail'

Scientists at Dana-Farber Cancer Institute have created a "cocktail" of immune-stimulating peptides they believe could provoke the body's defenses to attack multiple myeloma in its early "smoldering" phase and slow or prevent the blood cancer.
