Women with defects in lipoprotein metabolism may actually be able to bear children without complications

A group of Belgian researchers has determined that a pregnant woman's ability to metabolize fats is determined not only by her genes but by her baby's genes as well.

HapMap will give clues to many common diseases

Researchers say that they have completed a map that charts patterns of human genetic variation in the world population, to better understand human biology, evolution and how to diagnose diseases.

Lack of sex could be a signpost to extinction

Researchers from Imperial College London believe that when species become asexual they could be on their way to extinction.

Natural blood sugar level lowering compound could lead to new drugs to treat type 2 diabetes

A carbohydrate isolated from the liver lowers blood sugar levels after it is injected into diabetic rats, according to research carried out by a team of experts at the University of Virginia Health System (UVHS).

CSIRO's RNAi 'gene silencing' patents strengthened

The patent landscape for RNAi 'gene silencing' - including CSIRO's hairpin RNAi technology - has been significantly clarified following the resolution of several opposition and re-examination cases in Australia.

Mechanisms of evolution may be associated with disease

By comparing the human genome with that of the chimpanzee, man's closest living relative, researchers have discovered that chunks of similar DNA that have been flipped in orientation and reinserted into chromosomes are hundreds of times more common in primates than previously thought.

Study provides insight into cellular defenses against genetic mutation

With their latest discovery, researchers have significantly advanced the understanding of how human cells protect themselves from constant and potentially destructive changes in gene expression.

Gene therapy used to successfully treat heart failure

University of Pittsburgh investigators have for the first time used gene therapy to successfully treat heart failure and other degenerative muscle problems in an animal model that is genetically susceptible to a human muscular dystrophy.

Number of color-sensitive cones in the human retina differs dramatically among people

First-ever images of living human retinas have yielded a surprise about how we perceive our world.

Antisense molecules may hold promise in treating brain chemical problems such as Alzheimer's

Saint Louis University research shows a new class of drugs may hold promise in treating brain chemical problems such as Alzheimer's disease, says the principal investigator of research published in an early on-line version of Peptides.

Lack of gene expression associated with ovarian cancer

The expression of two specific genes is almost completely downregulated in ovarian cancer tumours. An extensive analysis of gene expression in ovarian cancer tumour cells has revealed this important finding, which should be an aid to early diagnosis.

Women satisfied with contralateral prophylactic mastectomy

Mayo Clinic researchers report that most women who have a contralateral (opposite to cancerous breast) prophylactic mastectomy (CPM) are satisfied and would elect this procedure again. Satisfaction with CPM was studied an average of 10 years after the procedure was done. The findings were published online Oct. 3 in the Journal of Clinical Oncology.

Faulty gene may identify those at risk of schizophrenia

Scientists believe they have discovered a genetic defect which could help explain the biological basis of schizophrenia.

Possible new directions for treatments for addiction to cocaine

Cocaine causes specific alterations in the brain's circuitry at a genetic level, including short-term changes that result in a high from the cocaine, as well as long-term changes seen in addiction, researchers from UT Southwestern Medical Center have found.

C. elegans, free-living soil nematodes, pave way for better anesthetics

Ten genes that may make patients more or less susceptible to a common anesthetic agent have been identified by researchers using tiny worms and sophisticated technology that eliminates the activity of individual genes.

Teens with missing part of a chromosome confirm genetic role in schizophrenia

A study in youth who are missing part of a chromosome is further implicating a suspect gene in schizophrenia.

Dopamine link to psychiatric and neurological disorders

A gene that regulates dopamine levels in the brain is involved in the development of schizophrenia in children at high risk for the disorder, say researchers at the Stanford University School of Medicine, Lucile Packard Children's Hospital and the University of Geneva.

Natural selection has played an important role in patterning the human genome

The most detailed analysis to date of how humans differ from one another at the DNA level shows strong evidence that natural selection has shaped the recent evolution of our species, according to researchers from Cornell University, Celera Genomics and Celera Diagnostics.

23 Oct 2005

Scientists discover molecular structure related to cell growth and cancer

Researchers discovered a special type of molecular structure that helps keep genes properly turned off until the structure is ejected from those genes in a regulated manner to help turn the genes on.

23 Oct 2005

Gene found only in men is altered by a chemical process, which is in turn linked to aggressive forms of melanoma

New scientific evidence that may shed light on why men are more likely than women to develop aggressive forms of skin cancer has been published in Carcinogenesis.
