Apoptosis is programmed cell death, the body's normal method of disposing of damaged, unwanted, or unneeded cells.

Protein that protects the body from tissue damage also increases the risk of tumors

You win some, you lose some. A protein that protects the body from tissue damage also increases the risk of tumors, according to a study conducted at Washington University School of Medicine in St. Louis. Moderate reduction of the protein level protects against tumor formation but increases susceptibility to tissue injury.

Strawberries most effective at inducing cancer cell death

Strawberries may be the most effective of the five most commonly consumed berries at inducing cancer cell death, according to a recent study conducted at the UCLA Center for Human Nutrition.

Arf gene prevents excessive growth of blood vessels in the developing eye

A gene better known for its role in preventing cancer also plays a key role in the developing embryo, where the gene prevents excessive growth of blood vessels, according to investigators at St. Jude Children's Research Hospital.

Biological breakthrough that could offer new hope in the fight against liver cancer

Professor John Mayer and Dr Simon Dawson, in collaboration with colleagues at Japan's Kyoto University, have discovered the function of a new liver oncoprotein - or cancer causing protein - which could be the first step to finding effective new treatments for the deadly illness.

New research suggests that accumulation of amyloid-beta peptides in cerebral blood vessels causes vascular damage in Alzheimer's disease

New research suggests that accumulation of amyloid-â peptides in cerebral blood vessels, as opposed to the brain itself, may be a more important pathological mediator of Alzheimer's disease. Two independent yet related articles describe such findings in the August issue of The American Journal of Pathology.

New molecular insights may one day lead to opportunities to stave off old age

Delving deep into the molecular subtleties of a strain of mice engineered to age rapidly, scientists have found that an accumulation of genetic mutations prompts a cascade of programmed cell death that seems to underpin the aging process.

Curcumin has potent anticancer powers

Curcumin, a spice commonly used in curries and other south Asian cooking, blocks a key biological pathway needed for development of melanoma and other cancers, say researchers from the University of Texas M. D. Anderson Cancer Center.

Good news for curry wallahs, ingredient helps fight cancer

In good news for curry wallahs, researchers are saying that a compound that makes curry yellow could help fight skin cancer.

Study is the first to show that there are mechanisms in place for the immune system to identify cancer cells

A study undertaken by biologists at the University of California, Berkeley, has found that damage to a cell's DNA sets off a chain reaction that leads to the increased expression of a marker recognized by the body's immune system.

Cancer cells may be able to avoid destruction by anti-vascular and anti-angiogenesis agents

Cancer cells may be able to avoid destruction by anti-vascular and anti-angiogenesis agents through a cellular stress response that activates a pro-survival protein called GRP78, according to researchers from the Keck School of Medicine of the University of Southern California.

Researchers find enzyme vital for controlling the early stages of cell death

Researchers at UT Southwestern Medical Center have found an enzyme vital for controlling the early stages of cell death - a beneficial and normal process when it works right, but malignant in a variety of cancers when it malfunctions.

Pomegranate juice may help babies resist brain injuries from low oxygen

Expectant mothers at risk of premature birth may want to consider drinking pomegranate juice to help their babies resist brain injuries from low oxygen and reduced blood flow, a new mouse study from Washington University School of Medicine in St. Louis suggests.

Study causes big shift in how we think about p53 gene

The cellular cascade of molecular signals that instructs cells with fatally damaged DNA to self-destruct pivots on the p53 tumor suppressor gene. If p53 is inactivated, as it is in over half of all human cancers, checks and balances on cell growth fail to operate, and body cells start to accumulate mutations, which ultimately may lead to cancer.

AAV2 has great potential to be developed as an anti-cancer agent

Six days is all it takes for a common, non-disease-causing virus to kill cervical, breast, prostate and squamous cell cancer cells in laboratory cultures, according to Penn State College of Medicine researchers.

Women who have a special genetic profile can conceive spontaneously after the age of 45 years

Dr. Neri Laufer, from the Hadassah University Hospital, Jerusalem, Israel, told the conference that his team's work to identify a specific gene expression profile linked to later fertility would help understanding of the ageing process, as well as enabling the development of better treatments for infertility in older patients.

Cockroach holds secret of women's fertility

The suggestion that a woman’s reproductive history may affect her ability to have children in the future has been a puzzle to scientists for years.

Researchers use RNAi libraries to identify regulators of apoptosis and chemoresistance

Using targeted RNA interference, or RNAi libraries, researchers at Harvard Medical School describe the first large-scale classification of kinase and phosphatase gene families on the basis of their role in apoptosis and cell survival. This study appears in the June issue of Nature Cell Biology.

MicroRNAs play an important role in human cancer

Over the past few years, scientists have discovered that a new class of genetic regulators called "microRNAs" influences normal human growth and development. Now, researchers have found that microRNAs also play an important role in human cancer. The findings are published in today's issue of the journal Nature (June 9).

New study shows tiny RNAs intimately associated with cancer

In discoveries that may open a new chapter in understanding and diagnosing cancer, Howard Hughes Medical Institute (HHMI) investigators and their colleagues have established that tiny microRNAs provide a novel genetic route to the initiation of some forms of cancer.
