Genzyme begins gene transfer trial for peripheral arterial disease

Genzyme Corporation announced today that the first patient has been treated in a new phase 2 clinical trial examining the safety and effectiveness of locally delivered gene transfer for patients with peripheral arterial disease.

Scientists have regenerated a damaged optic nerve

This achievement, which occurred in laboratory mice and is described in the March 1, 2005 issue of the Journal of Cell Science, holds great promise for victims of diseases that destroy the optic nerve, and for sufferers of central nervous system injuries.

Protein called CK2 plays a deadly role in colorectal carcinoma

A protein called CK2 plays a deadly role in colorectal carcinoma by blocking the ability of these tumors to activate a natural self-destruct mechanism that would clear this cancer from the body. This finding, by researchers at St. Jude Children's Research Hospital, is currently published in the online edition of Oncogene.

Cutting edge technology identifies genes that are involved in the development of Alzheimer's disease

Phoenix-Researchers at the Translational Genomics Research Institute (TGen) and Kronos Science Laboratories, an affiliate of Phoenix-based Kronos Optimal Health Company, have initiated a study with unprecedented power to identify genes that are involved in the development of Alzheimer's disease, the most common form of disabling memory and thinking problems in older persons.

Researchers have identified a protein called HIF-2a, which is important in retina formation

Hoping to prevent blindness in premature babies, UT Southwestern Medical Center researchers have identified a protein that responds to oxygen levels in cells and tissues and also affects the developing eye.

Scientists have replicated hepatitis C virus (HCV) in the laboratory

For the first time, scientists have replicated hepatitis C virus (HCV) in the laboratory. The ability to replicate HCV in cell culture will allow researchers to better study the life cycle and biology of this virus and to test potential antiviral compounds, which may lead to new therapies for the liver disease that results from infection with HCV.

Differing forms of taste genes mean that we all live in our own unique taste world

A study published in the February 22 issue of Current Biology confirms the influential role of genetics in determining the wide range of human sensitivity to taste, ultimately impacting how we each perceive the world in a slightly different way.

Secreted signaling protein called Wnt10b secret to new drugs for preventing or treating osteoporosis

Leaping tall buildings in a single bound may be out of the question, but the genetically engineered "supermice" in Ormond MacDougald's laboratory at the University of Michigan Medical School are definitely stronger than average.

Why some lung cancers stop responding to the drugs erlotinib (Tarceva) and gefitinib (Iressa)

Researchers at Memorial Sloan-Kettering Cancer Center (MSKCC) have found an explanation for why some lung cancers stop responding to the drugs erlotinib (Tarceva) and gefitinib (Iressa).

Crystallized molecular machine reveals possible new paths for treating diseases

The crystallized form of a molecular machine that can cut and paste genetic material is revealing possible new paths for treating diseases such as some forms of cancer and opportunistic infections that plague HIV patients.

New clues to amyloidoses

Familial amyloid polyneuropathy (FAP), a hereditary disease characterised by abnormal deposits of insoluble protein in the organs, results from a mutation in a single gene (the transthyretin or TTR gene). Nevertheless, disease incidence and age of onset can vary significantly between patients what have always puzzled scientists.

Lack of collagen increases likelihood of osteoarthritis

Duke University Medical Center researchers have found that joints whose cartilage lacks a specific type of collagen will develop osteoarthritis – the so-called "wear-and-tear" form of the disease – at a greatly accelerated rate.

Americans support appropriate use of reproductive genetic testing

A majority of Americans believes it is appropriate to use reproductive genetic testing to avoid having a child with a life-threatening disease, or to test embryos to see if they will be a good match to provide cells to help a sick sibling, a new report of the Genetics and Public Policy Center reveals.

Genetic signature that can identify breast cancer patients at high risk of distant recurrence

Researchers have discovered a genetic signature that can identify breast cancer patients at high risk of distant recurrence, reporting their results in this week’s issue of The Lancet.

Studies reveal methods viruses use to sidestep immune system

A series of studies by researchers at UT Southwestern Medical Center sheds light on the mechanisms used by viruses to thwart a host's immune defenses and may aid in the development of more effective drugs to fight hepatitis C and West Nile viruses, as well as the flu and the common cold.

GenoMed files gene patents

GenoMed has filed a patent application on two additional genes linked to common cancers. These genes are the third and fourth identified as a result of GenoMed's research in 2005 to date. They have the potential to improve the outcomes for those individuals afflicted with these cancers.

Separating chromosomes improves genetic test results

A new process that helps unmask genetic mutations by separating chromosomes so they can be studied individually may improve the diagnostic yield of some genetic tests, according to findings of a Colon Cancer Family Registry study published today in the Journal of the American Medical Association.

Single gene variant may increase a man's risk of prostate cancer by 50%

In 2001, Mount Sinai researchers published a study in Science that showed that a gene, known as KLF6, fails to function properly in at least 50 to 60 percent of all prostate cancers. This was the first single gene shown to be responsible for the majority of cases of this disease, which affects approximately 200,000 men each year.

Antigens produced by the Epstein Barr virus may provide an ideal target for cancer therapy

A typically innocuous virus found in 90 percent of people worldwide is the key to a new treatment for a cancer particularly common in North Africa and Southeast Asia.

Nanoscale mechanism to externally control the function and action of a protein

"We can switch a protein on and off, and while we have controlled a specific protein, we believe our approach will work with virtually any protein," said Giovanni Zocchi, assistant professor of physics at UCLA, member of the California NanoSystems Institute and leader of the research effort. "This research has the potential to start a new approach to protein engineering."
