New pathway identified by which cancer cells grow and survive

Cancerous tumors are wildly unfavorable environments. Struggling for oxygen and nutrients while being bombarded by the body's defense systems, tumor cells in fact require sophisticated adaptations to survive and grow.

Nanorods of gold blast tumor cells

Researchers have shown how tiny "nanorods" of gold can be triggered by a laser beam to blast holes in the membranes of tumor cells, setting in motion a complex biochemical mechanism that leads to a tumor cell's self-destruction.

Researchers working on the development of drugs to limit neuronal death

Neurons die en masse when the spinal cord is injured or when a person suffers a stroke. Researchers of the Max Delbrueck Center for Molecular Medicine (MDC) Berlin-Buch, Germany, and of Aarhus University, Denmark, have unraveled the molecular mechanism which causes the death not only of damaged neurons, but also of healthy nerve cells.

Important insights into blood vessel formation

Researchers have identified a molecular pathway that plays a critical role in the growth of blood vessels.

Six years advance warning of Alzheimer's

One of the most distressing aspects of Alzheimer's disease is the difficulty in determining whether mild memory problems are the beginning of an inevitable mental decline.

Obese people six times more likely to develop oesophageal cancer

Rates of oesophageal cancer have been rising rapidly, and in some countries, they have risen faster than those of every other major cancer, say the authors.

Gene may hold key to future cancer hope

Scientists may have discovered a new way of killing tumours in what they hope could one day lead to alternative forms of cancer treatments.

Re-educating immune system cells slows tumour growth

Immune system cells recruited by cancers to help them grow and spread could be 're-educated' to attack the tumours instead of aiding them, Cancer Research UK scientists announced at the National Cancer Research Institute (NCRI) Conference in Birmingham today (Wednesday).

Ozone impairs the body's immune system

According to a new study not only does air pollution exacerbate heart problems but it also impairs the body's immune system.

Early stage drug shows promise against cancer cells from young patients

A new drug has shown promising pre-clinical activity against cells from several types of children's cancers, scientists reveal at the National Cancer Research Institute Conference in Birmingham today (Tuesday).

Inhaled ozone impairs the body's first line of defense

As policy makers debate what levels of ozone in the air are safe for humans to breathe, studies in mice are revealing that the inhaled pollutant impairs the body's first line of defense, making it more susceptible to subsequent foreign invaders, such as bacteria.

Loss of TDP-43 gene found to be related to age-related neurological disorders

Researchers at Mayo Clinic in Jacksonville have discovered how loss of a gene can lead to accumulation of toxic proteins in the brain, resulting in a common dementia, and they say this mechanism may be important in a number of age-related neurological disorders.

Discovery of new pathway causing cell death related to frontotemporal dementia and ALS

Scientists have discovered a link between a mutated gene and a protein found in dead brain cells of people who suffer from a form of dementia and other neurological disorders.

Mutation of the COX2 gene can double or treble a woman's risk of ovarian cancer

Researchers in Portugal have discovered that a specific mutation of the COX2 gene seems to play a role in the onset of ovarian cancer, increasing women's susceptibility to developing the disease.

Manipulating immune response provides new approach to liver failure

If the results of the animal study can be applied in human patients, the approach may be able to keep patients alive until donor organs become available or to support liver function until the organ can regenerate itself, eliminating the need for a transplant.

Novel strategy to tackle acute myelogenous leukemia

A novel strategy to hopefully beat into oblivion one of the most aggressive forms of acute myelogenous leukemia combines the strengths of some of the newest leukemia agents, researchers say.

Molecular fingerprint of breast cancer drug resistance can predict response to treatment

A way of predicting which patients will respond well to treatment with a common chemotherapy drug used in breast cancer was unveiled at the European Cancer Conference (ECCO 14).

Acute loss of intestinal CD4+ T cells is not predictive of SIV virulence

A sudden loss of T cells -- white blood cells crucial to the immune system -- is not the trigger for the onset of AIDS, according to a study published in the September 2007 issue of the Journal of Immunology by a team of researchers at Tulane National Primate Research Center.

Scientists decipher mechanism behind antimicrobial 'hole punchers'

In the battle against bacteria, researchers have scored a direct hit.

21 Sep 2007

Process of necrosis redefined in landmark study

A new study led by investigators from the University of Pittsburgh School of Medicine demonstrates that the process of necrosis, long thought to be a chaotic, irreversible pathway to cell death, may actually be triggered as part of a regulated response to stress by a powerful protein, SRP-6, that can potentially halt necrosis in its path.
