Scientists pinpoint central elements of cell division

Scientists at Warwick Medical School have uncovered the molecular process of how cells are by-passing the body's inbuilt 'health checkpoint' with cells that carry unequal numbers of chromosomes that have a higher risk of developing cancer.

Inhibiting Notch signalling makes hormone-receptor positive cells dependent on estrogen

Within many hormone-receptor positive breast cancers lives a subpopulation of receptor-negative cells - knock down the hormone-receptor positive cells with anti-estrogen drugs and you may inadvertently promote tumor takeover by more dangerous, receptor-negative cells.

Researchers discover key enzymes that are critical for sperm function

Compared to most other cells in an organism, sperm undergo a radical transformation to become compact and mobile delivery systems for paternal DNA. Even though sperm looks and moves quite differently across species, SF State researcher Diana Chu and colleagues now say that there are at least a few key enzymes that are critical for sperm development and mobility in species as different as mice and nematode worms.

PSTC, FNIH Biomarkers Consortium launch clinical study to improve detection of kidney injury

The Foundation for the National Institutes of Health (FNIH) Biomarkers Consortium announced today the launch of a two-year clinical study aiming to advance the acceptance of new biomarkers designed to detect drug-induced kidney injury in clinical trials.

Study supports existence of metastable frequency-band-dependent scaffold of brain connectivity

Over the past two decades, the increased ability to analyze relationships among neural structures has provided novel insights into brain function. Most network approaches, how-ever, focus on static representations of the brain's physical or statistical connectivity.

No evidence of increased breast cancer risk for non-carriers of genetic mutations

Mothers, sisters and daughters from breast cancer families with known genetic mutations do not all share the same high risk of developing the disease, according to a new international study involving the University of Melbourne.

TERE1 gene mutation also contributes to invasive bladder cancer

Research conducted by Dr. Jayne S. Weiss, Professor and Chair of Ophthalmology at LSU Health Sciences Center New Orleans, and colleagues has found that a defect in a gene involved in a rare disease of the cornea also contributes to the progression of invasive bladder cancer.

NIH-funded project to discover biomarkers for type 2 diabetes

Arizona State University will lead a four-year, $5 million expanded initiative sponsored by the National Institutes of Health to discover proteins, or biomarkers, to help predict cardiovascular disease and to assess potential new treatments in people with type 2 diabetes.

Age is no longer a barrier to allogeneic stem cell transplantation

Age alone no longer should be considered a defining factor when determining whether an older patient with blood cancer is a candidate for stem cell transplantation. That's the conclusion of the first study summarizing long-term outcomes from a series of prospective clinical trials of patients age 60 and over who were treated with the mini-transplant, a "kinder, gentler" form of allogeneic (donor cell) stem cell transplantation developed at Fred Hutchinson Cancer Research Center.

Health risk associated with harmful substances in food may be underestimated

Mice are often used to test whether substances in food are harmful to humans. This requires that mice and humans metabolise substances in the same way. Humans have certain enzymes in more parts of the body than mice. The health risk associated with harmful substances in food may therefore be underestimated.

Researchers identify small-molecule drug candidates for many metabolic conditions

A new discovery by Californian scientists may lead to a pharmaceutical breakthrough for a wide range of illnesses that involve the hydration of cells that line the inner surfaces of our body's organs and tissues. In a new report appearing in the FASEB Journal, the researchers describe how they used high-throughput screening to identify small-molecule drug candidates which help cells bypass defective channels that normally move salt and water through cell membranes.

First study to evaluate mycoestrogens in young girls

Puberty is a time in a girl's life considered highly sensitive to stimulation by the hormone estrogen and a critical window during which estrogen exposure could greatly influence the risk of breast cancer later in life. An early onset of puberty also has been consistently shown in studies to increase the risk of breast cancer.

Elevated body temperature helps certain types of immune cells to work better

With cold and flu season almost here, the next time you're sick, think twice before taking something for your fever. That's because scientists have found more evidence that elevated body temperature helps certain types of immune cells to work better.

Johns Hopkins breast cancer researcher wins BioMaryland LIFE Prize

A Johns Hopkins breast cancer researcher is the recipient of a $50,000 award designed to encourage rapid translation of her basic research on biomarkers into a commercially available test that could predict the best treatment options for some women with breast cancer.

Young microenvironment rejuvenates old stem cells

Old stem cells can be rejuvenated by being placed in a young microenvironment, research from The University of Texas Health Science Center San Antonio shows. This raises the possibility that patients' own stem cells may one day be rescued and banked to treat their age-related diseases.

Birth control shot may impair a person's memory

The birth control shot Depo Provera offers a convenient alternative for women who don't want to remember to take a daily pill. Ironically, research from Arizona State University has shown the shot actually may impair a person's memory.

Protective response to starvation may promote heart failure

A protective response to starvation may promote heart failure, according to a study just published in Cell Metabolism. Two proteins that team up to conserve energy when food is scarce also limit energy production in the heart—a situation that can prove fatal when the heart is stressed and in need of an energy boost.
