Tobacco may trigger pancreatic cancer

A new study finds tobacco may act as an environmental trigger for patients with an inherited genetic predisposition to pancreatic cancer.

Autophagy may even provide a clue to the mythical fountain of youth

The cells of higher organisms have an internal mechanism for chewing up and recycling parts of themselves, particularly in times of stress, like starvation and disease. But nobody is quite sure yet whether this recently discovered process protects cells, or causes damage.

New understanding of the role viruses play in the development of autoimmune diseases

Researchers at the La Jolla Institute for Allergy & Immunology have added a significant milestone to scientific understanding of the role viruses play in the development of autoimmune diseases, such as diabetes.

Crystal structure of protein AIRs kinase uncovered

Cornell University researchers, who are trying to understand how proteins evolve and function by looking at their structural features, have uncovered the crystal structure of a protein involved in making the building blocks of DNA correctly.

Sperm cells grown in laboratory culture

A team of researchers working with cells from mice has overcome a technical barrier and succeeded in growing sperm progenitor cells in laboratory culture.

Long-term safety of transplanted pig cells to humans confirmed

Living Cell Technologies Limited has published a paper in the November issue of the Journal of Clinical Microbiology which demonstrates the long-term safety of transplanted insulin-producing pig islets in people with type 1 diabetes.

Genetic mutations could collectively raise bowel cancer risk

Cancer Research UK scientists at the University of Oxford have found that a number of genetic mutations could collectively raise bowel cancer risk, reporting their findings in the journal PNAS.

Urinary incontinence is passed down from mother to daughter

New research from the University of Bergen (UiB), Norway, shows that a woman who’s mother has urinary incontinence has a 30 percent greater chance for incontinence herself.

Gene regulated by need to process proteins linked to enlargement of protein processing factory

Part of a cellular mechanism that regulates the folding of new proteins into their proper shapes also includes a genetic response that enlarges the factory where both protein folding and packaging of proteins occurs.

The Human Fertilisation and Embryology Authority has issued a preimplantation genetic diagnosis (PGD) licence for inherited colon cancer

The Human Fertilisation and Embryology Authority has confirmed that it has issued a preimplantation genetic diagnosis (PGD) licence for Familial Adenomatous Polyposis Coli (FAP) to the Assisted Conception Unit at University College Hospital, London.

Reproductive hormones have effects on all of these stages of brain growth and development

Scientists are now uncovering increasing evidence that the brain not only responds to hormones produced by the reproductive system, but that these hormones-the so-called "female hormones," estrogen and progestin, and the "male" androgens, such as testosterone-play an important role in the development of differences between male and female brains.

Genetic link suggested in deaths from cardiac valve diseases

Deaths from cardiac valve diseases appear to run in families, suggesting a significant genetic component, according to a study published in Circulation: Journal of the American Heart Association.

An errant enzyme linked to bipolar disorder impairs awareness, perception and reasoning

The disturbed thinking, impaired judgment, impulsivity, and distractibility seen in mania, a destructive phase of bipolar disorder, may be traceable to overactivity of protein kinase C (PKC), suggests the study, funded by the National Institute of Mental Health (NIMH) and National Institute on Aging (NIA), and the Stanley Foundation.

Improved risk classification for patients with acute lymphoblastic leukemia offers hope for eliminating irradiation

Improved risk classification for patients with acute lymphoblastic leukemia (ALL), coupled with more intensive intrathecal chemotherapy for high risk patients and the use of a drug called dexamethasone, could one day permit physicians to omit irradiation as a part of routine treatment.

The microorganisms that normally live in the gut can increase body fat

The microorganisms that normally live in the gut can increase body fat, say researchers at Washington University School of Medicine in St. Louis. They found that gut microbes can open the "gates" fat uses to enter the body's fat cells.

First home-testing device for phenylketonuria (PKU) patients

Home-testing kits have made it easier for diabetics and hypertension patients to track their conditions, but such self-monitoring hasn’t been possible for people with phenylketonuria (PKU).

Grant to develop high speed DNA sequence reader

Sequencing of the human genome is one of the major scientific advances of our time. But with 3 billion base pairs, initial sequencing of the human genome took 11 years and cost $1 billion to complete in 2002. Today, it costs up to $50 million to sequence 3 billion base pairs.

Cellular enzyme represents a potential new target for developing improved HIV drugs

Scientists have discovered that a cellular enzyme helps ferry HIV genetic instructions out of the cell nucleus where they can then be translated into proteins to begin their most destructive work.

New role for a key protein involved in muscle contraction

Overturning a scientific stereotype, researchers at the University of Illinois at Chicago have discovered a new role for a key protein involved in muscle contraction and shown it is present not just in the cytoplasm of cells but in the nucleus as well.

Genetic evidence to support an inherited tendency to retain salt

Researchers at the University of Chicago have found genetic evidence to support the sodium-retention hypothesis, a controversial 30-year-old theory that the high rate of hypertension in certain ethnic groups is caused, in part, by an inherited tendency to retain salt.
