Urine actually helps a particular yeast stick to cells along the urinary tract

The finding might offer a new way to prevent or treat certain yeast and fungal infections, and the researchers' work also provides an unexpected new role for some proteins already known to help hungry yeast live longer.

Protein Mnd2 protects chromosome bonds

The protein Mnd2 inhibits premature separation of chromosomes during the formation of gametes. The now published discovery of this regulatory function may help to understand the origin of some common congenital chromosome defects.

Gene named ATBF1 may contribute to the development of prostate cancer

A gene named ATBF1 may contribute to the development of prostate cancer through acquired mutations and/or loss of expression, according to research at Emory University School of Medicine and its Winship Cancer Institute.

X-Chromosome has the big story!!

The human genome is said by some to be the "book of life," and the X-chromosome a large part of the the plot. A team of genome researchers have described the nature of this mysterious "chapter" in the DNA story.

Neuronal death and processing of Tau protein in Alzheimer’s Disease (AD)

In a research report recently published in the Journal of Alzheimer's Disease, published by IOS Press, a research group from the International School for Advanced Studies (ISAS\SISSA) in Trieste (Luisa Fasulo, Gabriele Ugolini e Antonino Cattaneo) showed that a processed form of tau protein induces neuronal death by apoptosis (programmed cell death) when expressed in cultured rat hippocampal neurons.

Gene identified that confers susceptibility to age-related macular degeneration

By combining the tools of high-throughput biology and statistical genetics, scientists at Rockefeller University, Yale University School of Public Health and the National Eye Institute have identified a gene that confers susceptibility to age-related macular degeneration (AMD), the most common cause of vision loss in the United Sates for those over 60.

DNA weak links may provide clues to cancer biology

The chromosomes of mammals, including humans, contain regions that are particularly prone to breaking under conditions of stress and in cancer. Now, new research by geneticists at Duke University Medical Center finds that yeast cells also contain such weak links in DNA and begins to reveal the molecular characteristics of these links that might help to explain them.

Gene for AMD has now been identified by researchers

Age-related macular degeneration (AMD) is a debilitating eye disease affecting about 15 million people in the United States.

Mouse gene shows new mechanism behind cardiac infarction in man

A gene that, in different variants, increases or decreases the level of atherosclerosis has been identified in mice. The corresponding human gene has been shown to play a role in the development of myocardial infarction.

Telomerase finding has major implications for cancer

UCLA biochemists have determined the three-dimensional structure of a major domain of telomerase, the enzyme that helps maintain telomeres - small pieces of DNA on the ends of chromosomes that act as protective caps - allowing DNA ends to be copied completely when cells are replicated.

Discovery gives clinicians new targets for making existing therapies more effective and developing drugs to inhibit the growth of cancers

A team of researchers at the University of Alberta in Edmonton and the Samuel Lunenfeld Research Institute in Toronto have discovered how a key enzyme involved in repairing DNA is put together and how it works--a development that opens up new therapies for making cancer cells more vulnerable to attack.

Abnormal brain structure tied to spatial, numerical thinking problems when children lack part of chromosome

Certain genetic diseases affect children's educational abilities in a distinctive pattern: impairing their numerical abilities more than their verbal skills. New research sheds light on this split in abilities by investigating how differences in brain structures may influence how the mind works.

Gene variant that may increase the risk of late-onset Alzheimer's disease

Researchers from the MassGeneral Institute for Neurodegenerative Disorders (MIND) have identified a gene variant that may increase the risk of late-onset Alzheimer's disease.

Scientists gain new insight into DiGeorge syndrome

A collaboration of European scientists has uncovered new insight into the most common chromosomal microdeletion syndrome in humans.

Methylphenidate linked to chromosomal changes

In a small but startling preliminary new study, Texas researchers have found that after just three months, every one of a dozen children treated for attention deficit/hyperactivity disorder (ADHD) with the drug methylphenidate experienced a threefold increase in levels of chromosome abnormalities—occurrences associated with increased risks of cancer and other adverse health effects.

Pollution exposure during pregnancy can cause chromosomal abnormalities in fetal tissues

A new study of newborns in New York City reveals that prenatal exposure to combustion-related urban air pollutants alters the structure of chromosomes (the carriers of genes) of babies in the womb.

Vaccine that boosts the immune response could improve the effect of conventional treatment for patients with chronic myeloid leukaemia

CML is caused by the breakage and swapping of chromosomes 9 and 22, which results in a shortened chromosome called the Philadelphia chromosome. Cells with the abnormal chromosome make a protein that encourages aberrant growth and division. Patients with CML can be treated with a drug called imatinib or interferon alfa.

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.

Novel genetic test helps detect mutations that may be missed by conventional DNA test

Researchers have identified a genetic test that when used with DNA testing would detect a higher number of genetic mutations in colorectal cancer patients, according to a study in the February 16 issue of JAMA, a theme issue on medical applications of biotechnology.

Angiogenesis inhibitor molecules defend against the development and spread of cancer

Research led by investigators at Beth Israel Deaconess Medical Center (BIDMC) helps explain how a group of angiogenesis inhibitor molecules serve as an important defense mechanism against the development and spread of cancer, offering key insights into why cancerous tumors grow at different rates among different individuals.
