SENP1 protein may provide a basis for future targeted cancer therapies

Researchers at the University of Texas M. D. Anderson Cancer Center have found a protein that enables cellular survival during periods of low oxygen, or hypoxia, which also is key for development of many kinds of cancer.

Discovery of master switch that regulates blood pressure

A team of Oregon Health & Science University researchers studying a rare form of hypertension has identified the mechanism by which they believe a protein complex in the kidney operates as a master switch that regulates blood pressure, a finding that has broad implications for the treatment of more common forms of hypertension.

Not just humans benefit from animal biotechnology

Laboratory animals are the source of major discoveries and breakthroughs in biology, not just in tackling disease but also unravelling fundamental molecular processes.

Researchers discover genes linking stress, high blood pressure, alcoholism and tobacco addiction

A team led by a Heart and Stroke Foundation researcher has uncovered a series of genes linking mental stress, high blood pressure, alcoholism and tobacco addiction.

Transgenics sped up

A new method of constructing artificial plant chromosomes from small rings of naturally occurring plant DNA can be used to transport multiple genes at once into embryonic plants where they are expressed, duplicated as plant cells divide, and passed on to the next generation -- a long-term goal for those interested in improving agricultural productivity.

X chromosomes and evolution

Researchers at the University of Rochester believe they have just confirmed a controversial theory of evolution.

Is there really a 'mommy' gene in women?

Basic principles of biology rather than women's newfound economic independence can explain why fewer of them are getting married and having children, and why the trend may only be temporary, says a Queen's researcher.

Study looks at mitochondrial variation in sperm traits and sperm competitive ability

University of Nevada, Reno researchers Jeanne and David Zeh of the Department of Biology have received a five-year, $650,000 grant from the National Science Foundation to investigate the effects of natural mitochondrial variation on sperm traits and sperm competitive ability.

JAK genes and cancer

Cancer-causing genes can work in more powerful and sneaky ways than have been realized.

The importance of gene regulation for common human disease

A new study published in Nature Genetics on Sunday 16 September 2007 show that common, complex diseases are more likely to be due to genetic variation in regions that control activity of genes, rather than in the regions that specify the protein code.

Selection on genes underlying schizophrenia during human evolution

Several genes with strong associations to schizophrenia have evolved rapidly due to selection during human evolution, according to new research in the Proceedings of the Royal Society B (Wednesday 5 September 2007).

Discovery suggests location of genes for breast density, a strong risk factor for breast cancer

Studying the DNA of 889 people, gene hunters at the Mayo Clinic and H. Lee Moffitt Cancer Centers have identified a region on chromosome 5p that is significantly associated with dense breast tissue, a known risk factor for breast cancer.

Brain areas that control attention thinnest in children with ADHD

Brain areas that control attention were thinnest in children with attention deficit hyperactivity disorder (ADHD) who carried a particular version of a gene in a study by the National Institutes of Health's (NIH) National Institute of Mental Health (NIMH).

The future of Alzheimer's disease research

Imagine the day when a routine visit to the family doctor includes a simple blood test to predict the risk for developing Alzheimer's disease (AD).

Women's HIV/AIDS conference delegates develop action plan to foster women's, girls' leadership in fight against disease

Delegates on Saturday at the close of the first International Women's Summit on Women's Leadership and HIV and AIDS in Nairobi, Kenya, released a 10-point action plan that aims to foster leadership roles of women and girls in the fight against HIV/AIDS, the Nation/AllAfrica.com reports.

Men and women with multiple sclerosis equally transmit the genetic risk of the disease to their children

The research contradicts the results of a recent study, which found affected fathers were more likely than affected mothers to transmit the risk of developing MS to their children.

Scoliosis gene found

Physicians have recognized scoliosis, the abnormal curvature of the spine, since the time of Hippocrates, but its causes have remained a mystery -- until now. For the first time, researchers have discovered a gene that underlies the condition, which affects about 3 percent of all children.

True nature of heterochromatin revealed

Not so long ago, the difficult-to-sequence, highly repetitive, gene-poor DNA found in regions of chromosomes known as heterochromatin was called "junk." Like dark matter in the universe, the true nature of heterochromatin was unknown.
