Morphine blocks new blood vessel and tumor growth: Study

Current research suggests that taking morphine can block new blood vessel and tumor growth. The related report by Koodie et al, "Morphine suppresses tumor angiogenesis through a HIF1α/p38MAPK pathway," appears in the August 2010 issue of the American Journal of Pathology.

New study reveals potential role of TGF-β1 in kidney disease

Fibrosis in the kidney is one of the key causes of progressive renal failure. High levels of the inflammatory molecule TGF-β1 in the kidney tubules due to tissue damage can cause fibrosis as well as nephron degeneration, resulting in loss of kidney function. To clarify the mechanisms regulating TGF-β1-mediated renal fibrosis, Koesters et al expressed high levels of TGF-β1 in renal tubules of mice. Nephron degeneration in this system was mediated by decomposition of the tubular cells. These data suggest that TGF-β1 may play a novel role in cell death of renal cells, thus contributing to renal fibrosis.

New drug to treat chronic pain in SCD patients

A University of Minnesota Medical School research team led by Kalpna Gupta, Ph.D., has discovered that cannibinoids offer a novel approach to ease the chronic and acute pain caused by sickle cell disease.Using a mouse model of SCD, Gupta and University of Minnesota colleagues studied the pain mechanisms by observing animals that exhibited both musculoskeletal pain and temperature sensitivity, symptoms similarly experienced by humans with SCD. The team compared two classifications of drugs in their ability to manage pain sensed by the animals, the traditionally prescribed classification of drugs, opioids, with a new therapeutic approach, cannabinoids, a synthetic compound based on marijuana derivatives. Currently, the only approved treatment for management of severe pain in SCD is opioids.

Natural, needle-free vaccination against malaria

If mice are administered an antibiotic for three days and are simultaneously infected with malaria, no parasites appear in the blood and life-threatening disease is averted. In addition, the animals treated in this manner also develop robust, long-term immunity against subsequent infections. This discovery was made by the team headed by Dr. Steffen Borrmann from the Department of Infectious Diseases at Heidelberg University Hospital in cooperation with Dr. Kai Matuschewski of the Max Planck Institute for Infection Biology in Berlin. The scientists think that safe and affordable prophylaxis with antibiotics in residents of areas with high malaria transmission has the potential to be used as a natural "needle-free" vaccination against malaria.

Olig1 and Olig2 genes are associated with Down syndrome, scientists identify

Down syndrome is a well known cause of mental retardation and other medical problems, including early onset of Alzheimer disease. It has long been known that Down syndrome is associated with an individual having an additional copy of chromosome 21. Research findings reported in the July 18 advanced online publication of Nature Neuroscience have narrowed down the critical genetic elements responsible for some aspects of Down syndrome.

GABA disrupts working memory in neurofibromatosis type 1 patients

Imagine if your brain lost its working memory - the ability to hold and manipulate information in your mind's eye. That's the plight faced by millions of people with neurofibromatosis type 1, or NF1. The genetic condition affects one in 3,500 people and is the most common cause of learning disabilities.Now a UCLA research team has uncovered new clues about how NF1 disrupts working memory. Published in the July 12 online edition of Proceedings of the National Academy of Sciences, the findings suggest a potential drug target for correcting NF1-related learning disabilities.

Penn researchers reverse cognitive decline in fruit flies with Alzheimer's gene mutation

Investigators have found that fruit fly (Drosophila melanogaster) males -- in which the activity of an Alzheimer's disease protein is reduced by 50 percent -- show impairments in learning and memory as they age. What's more, the researchers were able to prevent the age-related deficits by treating the flies with drugs such as lithium, or by genetic manipulations that reduced nerve-cell signaling.

Pre-clinical study results of EVP-0015962 presented at AAICAD 2010

EnVivo Pharmaceuticals today announced at the Alzheimer's Association 2010 International Conference on Alzheimer's Disease results from its proprietary gamma-secretase modulator pre-clinical study. In a transgenic mouse model, EnVivo's EVP-0015962 reduced amyloid plaque buildup which is believed to be a cause of Alzheimer's disease, reversed behavioral deficits and reduced brain inflammation associated with Alzheimer's disease.

New research focuses on calcium channels in lysosome membrane

In cells, as in cities, disposing of garbage and recycling anything that can be reused is an essential service. In both city and cell, health problems can arise when the process breaks down.

JNK protein controls cell cycle, new study reveals

Put simply, a tumor is the result of out-of-control cell growth. To assure that the cell cycle - the cell's process of duplicating itself to make more cells - goes smoothly, a large network of proteins tells other proteins what to do and when to do it. When any of these layers of protein regulation fail, cell growth can get out of hand. A new study led by Ze'ev Ronai, Ph.D., associate director of Sanford-Burnham's National Cancer Institute-designated Cancer Center, reveals a new player in cell cycle control.

New research studies presented at Alzheimer's Association International Conference

The primary therapeutic target in Alzheimer's disease has been the beta amyloid peptide, which clusters outside cells in the brain to form sticky clumps known as plaques. Recently, more attention has been given to the tau protein, which aggregates inside the brain cells of people with Alzheimer's, forming neurofibrillary tangles. Precisely how these proteins interact in causing the disease is unclear.

Studies support association of physical activity, diet with maintaining cognitive ability, reducing dementia risk

Evidence from three long-term, large-scale studies supports the association of physical activity and certain dietary elements (tea, vitamin D) with possibly maintaining cognitive ability and reducing dementia risk in older adults, according to new research presented today at the Alzheimer's Association International Conference on Alzheimer's Disease 2010 in Honolulu, HI.
