Extensive gene traffic, the process of genes leaving and arriving on the chromosome

Researchers at the University of Chicago have discovered there is extensive gene “traffic”—the process of genes leaving and arriving on the chromosome—on the mammalian X chromosome. They also have overturned a conventional theory about how genes evolved on the sex chromosome.

Scientists discover gene for Parkinson's disease

UCL scientists have discovered a new gene implicated in the early development of Parkinson's disease. In a study of families with early onset disease, Professor Nick Wood and colleagues at University College London's Institute of Neurology identified a novel gene which produces a malfunctioning protein that could pave the way for new treatments for Parkinson sufferers.

Genetic mutation raises interesting questions about the evolution of the Y chromosome

The names and dates comprising a family tree contain branches that can extend backward centuries in time. People use these diagrams to discover their ancestral origin. Scientists use them to study the genealogical origins of entire species, tracing evolutionary history down to changes in a single gene.

Autism gene discovered

Researchers at Mount Sinai School of Medicine are first to strongly link a specific gene with autism. While earlier studies have found rare genetic mutations in single families, a study published in the April issue of the American Journal of Psychiatry is the first to identify a gene that increases susceptibility to autism in a broad population.

The amount of female smokers rose by 600% in the 20th century

American women who smoke rose dramatically during the 20th century, resulting in a 600 percent increase by the year 2003 in the number of women who died of lung cancer. In the same period, the number of lung cancer deaths in men declined.

Bird flu in humans highlights vulnerability of people to emerging diseases

The occurrence of avian influenza in humans is a reminder of the vulnerability of people to an emerging pandemic, Mayo Clinic researchers warn in the current issue of Mayo Clinic Proceedings.

New research into Human Papilloma Virus (HPV) and Cervical Cancer

Cervical cancer is the second-most prevalent cancer in women and, despite encouraging improvements in screening leading to earlier detection, cervical cancer still kills many women every year. The risk of cervical cancer is increased by infection with certain types of human papilloma virus (HPV).

Surprises found In gene variation associated with schizophrenia

Approximately two percent of Caucasians have a gene segment variation that can cause a certain form of schizophrenia. Most people with the variation, known as a polymorphism, do not have the disease. A University of Iowa Health Care study reveals a good prognosis for people who do have this form of schizophrenia.

Protein kinase complex influences the outer layer of skin to control the eventual shape of the full-grown skeleton and skull

Continuing studies about an important regulatory protein kinase complex called I-kappa-B kinase (or IKK) have now shown that a subunit of IKK – IKK alpha – influences the outer layer of skin in developing mice to control the eventual shape of the full-grown skeleton and skull.

Molecular analyses of leukemia patients suggest strategies for better treatments

The cure rate for pediatric acute lymphoblastic leukemia (ALL) might continue to rise with improved use of conventional therapies. But even more effective and less toxic therapies based on genetic and pharmacogenetic studies might one day push the success rate close to 100 percent, according to an article published by investigators at St. Jude Children’s Research Hospital in the April 8 issue of the New England Journal of Medicine.

New research findings in study of Rett Syndrome

Rudolf Jaenisch of the Whitehead Institute of Biomedical Research in Cambridge, MA reports in the April 6, 2004 online issue of the Proceedings of the National Academy of Sciences that introduction of the MeCP2 protein into post-mitotic nerve cells of MeCP2 mutant mice rescues the symptoms of Rett Syndrome. This raises the possibility that neurons are functionally normal in a newborn child and that neural dysfunction manifests itself only later due to prolonged MeCP2 deficiency. If correct, therapeutic strategies aimed at preventing the onset of Rett symptoms could be initiated at birth.

Newly diagnosed breast cancer patients who test positive for BRCA1 and BRCA2 gene mutations are twice as likely as non-carriers to opt for a double mastectomy

Newly diagnosed breast cancer patients who test positive for BRCA1 and BRCA2 gene mutations are twice as likely as non-carriers to opt for a double mastectomy to reduce the risk of cancer in the opposite breast, according to the first large-scale study evaluating the impact of genetic counseling and testing on breast cancer treatment decisions.

The National Cancer Institute has awarded USC scientists $3.5 million for a study of the enzyme that faithfully copies our genetic information

The National Cancer Institute has awarded USC scientists $3.5 million for a study of the enzyme that faithfully copies our genetic information, enabling it to pass from one generation to the next. The grant will fund structural, biochemical and computer studies designed to reveal how the enzyme, DNA polymerase, makes so few mistakes.

Scientists have discovered that a non-genetic molecular process can effect cell behaviour

Genetic mutations, sudden, random and usually harmful changes to the structure of a gene, are only one factor that determines the ultimate fate of a cell. Chicago scientists have discovered that a non-genetic molecular process also can play a role, and that experimenters can influence this process in bacteria, they report in the April 1 issue of the journal Nature.

Research team has found a new way to streamline gene isolation to determine their functions

A single strand of plant or animal DNA may contain tens of thousands of genes, each programmed to produce a specific protein essential for the growth or survival of the organism. The challenge for geneticists is to isolate individual genes and determine their function -- a painstaking process often requiring years of laboratory trial and error.

Scientists find parallels between human speech and bird song which gives clues to human speech disorders.

The research by a team led by Stephanie White, UCLA assistant professor of physiological science, supports the theory that two genes shared by humans and songbirds, FoxP1 and FoxP2, may play a critical role in human speech, and speech disorders. The study is published March 31 in the Journal of Neuroscience.

Earlier detection of cancer with Transgenomic's WAVE(R) system

Transgenomic Inc. has announced that during the American Association of Cancer Research annual meeting currently underway in Orlando, several of its customers from major research institutions worldwide will present results in which the Company's WAVE System has played an important role.

Three of the world’s top women chemists visit UK to inspire young scientists

Three of the world’s top women chemists are visiting the UK this week (29 March - 2 April) to tour institutions and talk about their research with the aim of inspiring young scientists to emulate their achievements. The inaugural Rosalind Franklin International Lectureship Programme has been masterminded by Professor Susan Gibson, Imperial College London, who funded the initiative with her prize money from the Royal Society Rosalind Franklin Award.

Halting the development of certain pancreatic, ovarian, colon and lung cancers may be possible with new therapy

By investigating a single molecule that influences cell growth, a research group in the Purdue Cancer Center, including Brian S. Henriksen, has gained new insight into the chain of events that make some cancer cells divide uncontrollably, insight that may eventually lead to a way to break that chain, stopping cancer in its tracks. The molecule, known as Icmt, has a critical role in the development of Ras, an ordinarily beneficial protein that tells a cell to divide. The research group has determined how to inhibit Icmt's influence on Ras, without which the protein cannot develop effectively into an instigator of cell growth.
