Discovered of gene mutations associated with hereditary neuralgic amyotrophy

In a significant advance toward understanding a perplexing and painful neurological disorder, an international team of researchers has discovered gene mutations associated with an inherited chronic pain and weakness syndrome known as hereditary neuralgic amyotrophy (also called HNA).

Gene responsible for Neuralgic Amyotrophy identified

Neuralgic Amyotrophy is a painful disorder of the peripheral nervous system. This heritable disease causes prolonged acute attacks of pain in the shoulder or arm, followed by temporary paralysis.

Researchers map genetic location that explains why certain blood pressure-lowering drugs aren't effective for some people

"The findings bring us a step closer to developing targeted therapies for patients with high blood pressure who might otherwise be started on medications that won't help," said lead author Sandosh Padmanabhan, Ph.D.

Mutations in the gene, called PIG-A may help identify individuals at high risk for cancer

A new study to detect an elevated rate of mutations in a gene on the X chromosome holds promise for developing a test that could identify individuals at risk for developing cancer.

Definitive multiple sclerosis linkage screen

A cluster of genes on chromosome six is the only one that plays a significant role in multiple sclerosis (MS), according to the most complete genetic study to date in the disorder, presented at the 130th annual meeting of the American Neurological Association in San Diego.

Gene mutation may increase the risk of prostate cancer up to three times in African-American

Researchers have identified a gene mutation that may increase the risk of prostate cancer up to three times in African-American men with a family history of the disease.

Suppression of FOXO1a gene might kill resistant alveolar rhabdomyosarcoma (ARMS) tumors

FOXO1a caused death of tumor cells in laboratory study by triggering expression of caspase-3, which blocks cell division and causes cells to undergo apoptosis, according to St. Jude.

Acute-leukemia sign may signal need for different therapy

A type of chromosome change that was thought to predict a good response to treatment in patients with acute myeloid leukemia (AML) might actually signal the need for a different therapy to achieve the best outcome.

Manic depression linked to two chromosomal regions in the human genome

An international team of 53 researchers has offered the most convincing evidence so far linking bipolar disorder, also known as manic depression, to two chromosomal regions in the human genome. The finding gives scientists refined targets for further gene studies.

Workshop - stem cells in reproduction and in the brain

"Once we have found the factors by which body cells can be re-programmed into stem cells, then therapeutic cloning might become superfluous," said Hans R. Scholer, director of the Max Planck Institute for Molecular Biomedicine in Munster, Germany, at an international scientific symposium on stem cell research in Kobe, Japan.

Nitric oxide could one day help women in their 30s and 40s remain fertile longer

Researchers have found that an important chemical compound, nitric oxide, appears to slow or reverse the aging of eggs in mouse ovaries. The finding suggests nitric oxide could one day help women in their 30s and 40s remain fertile longer and increase their chances of having healthy babies, the scientists say.

Human embryonic stem cell lines accumulate changes in their genetic material over time

The findings do not limit the utility of the cells for some types of research or for some future clinical applications, the researchers say, but draw attention to the need to closely monitor stem cell lines for genetic changes and to study how these alterations affect the cells' behavior.

Significant advance in the study of small ribonucleic acids

Scientists from the University of Delaware have made a significant advance in the study of small ribonucleic acids (RNAs), discovering 10 times more small RNAs in the plant Arabidopsis than previously had been identified. The advance is reported in the Sept. 2 issue of Science magazine.

Overall genome landscape between chimps and humans can be attributed to large segmental duplications

A study comparing the genomes of both humans and chimpanzees has found that much of the genetic difference between the two species came about in events called segmental duplications, in which segments of genetic code are copied many times in the genome.

Human Y chromosome stays intact while chimp Y loses genes

The human and the chimpanzee Y chromosomes went their separate ways approximately 6 million years ago. But ever since this evolutionary parting, these two chromosomes have experienced different fates, new research indicates.

New tool to help unravel the function of an elusive DNA structure

A Rensselaer researcher has developed a new tool to help unravel the function of an elusive DNA structure. The findings, which were presented today at the 230th national meeting of the American Chemical Society (ACS) in Washington, D.C., could lead to a better understanding of diseases such as cancer and diabetes.
