Interaction between cell and virus provides scientists valuable insights into the development of safe viral vectors for use in oncology

When infected by a virus, a cell uses specific defense mechanisms developed in the course of a long evolution. Thus, it can activate enzymes that disrupt or prevent replication of the viruses within the cell.

Environment factors can interact with genetics to increase disease risk

New research shows that exposure to harmful chemicals and drugs during critical developmental periods early in life may actually "reprogram" the way certain genes respond to the female hormone estrogen. This genetic reprogramming may determine whether people with a genetic predisposition for a disease actually develop the disease.

Exposure to pharmaceutical estrogen during fetal development can permanently "reprogram" tissue in a way that determines whether tumors will develop in adulthood

Researchers at The University of Texas M. D. Anderson Cancer Center may have uncovered the reason why some people who are genetically predisposed to hormone-dependent cancers develop the disease as an adult, while others who are similarly susceptible don't.

New prognostic markers help identify risk of relapse

A recently completed clinical study has found new prognostic markers that may help clinicians identify those children with leukaemia who are at high risk of relapse and are most in need of intensified treatment to improve their chance of survival.

New gene linked to familial cancer

Scientists have identified a new gene that appears to be linked to a small but significant percentage of familial cancer cases – as well as seemingly randomly occurring malignancies.

Grapes inhibit cancer growth

Components in grapes, including some newly identified ones, work together to dramatically inhibit an enzyme crucial to the proliferation of cancer cells, say scientists at the University of Illinois at Urbana-Champaign.

Fasting every other day, while cutting few calories, may reduce cancer risk

New research at the University of California, Berkeley, raises such a possibility. It shows that healthy mice given only 5 percent fewer calories than mice allowed to eat freely experienced a significant reduction in cell proliferation in several tissues, considered an indicator for cancer risk.

Finding may open new horizons for understanding the initiation of chemically induced cancers

A team from the chemistry and biology departments of New York University, in collaboration with Memorial Sloan Kettering Cancer Center (MSKCC), has uncovered a conformational switch - a change in shape in a carcinogen-damaged DNA site - in tumor suppressor genes altered by a known cancer-causing chemical found in cigarette smoke.

Babies who weighed more at birth had higher rates of digestive and lymphatic cancers in adulthood

Medical experts have proposed associations between birth size and rates of adult cancer. To examine this hypothesis, researcher Valerie A. McCormack and colleagues at the London School of Hygiene & Tropical Medicine and the Universities of Uppsala and Stockholm investigated overall and site-specific cancer incidence in relation to birth characteristics in a Swedish population-based cohort.

Discovery of new compound known as SP-4-84 could lead to improved chemotherapy treatments

The discovery of a new compound by Michigan State University researchers could lead to improved chemotherapy treatments for different types of cancers – potentially with fewer side effects.

BMA Cymru Wales to petition parliament to ban smoking in public places unless Wales goes smoke free within 10 months

BMA Cymru Wales is seriously considering the possibility of petitioning Parliament for a ban in public places in Wales using the rarely used private bills procedure.

STAT3 protein could lead to new ways to prevent skin cancer

Scientists at The University of Texas M. D. Anderson Cancer Center have identified a protein that serves as a master regulator of skin cancer - a finding that could lead to new ways to prevent skin cancer before it starts.

The Bush Medicare Prescription has changed the identity of medical oncology

Under previous law, Medicare covered chemotherapy as well as radiation treatment for cancer patients, but did not pay for oral-dose anti-cancer drugs, unless they were available in both oral and injectable form.

Researchers have uncovered a specific signaling mechanism that contributes to the development of colorectal cancer

The discovery furthers the understanding of mechanisms that contribute to disease progression and provides new avenues for development of therapies for colorectal cancer.

New genetic mechanism has been identified linking diet to breast cancer

Experiments carried out by scientists at the Universitat Autònoma de Barcelona on experimentally induced breast cancer tumours in laboratory rats show that an excess of certain fats in the diet, commonly known as omega-6, accelerates breast cancer, increasing the malignancy of the disease.

Fish oils appear to reduce breast cancer risk

Researchers who found that fish oils appear to reduce breast cancer risk have now discovered that the oils may especially benefit women with particular genetic makeups.

HER-2 cell surface receptors tun on genes associated with carcinogenesis

Researchers at The University of Texas M. D. Anderson Cancer Center now have evidence that receptors found on tumors that were believed to function only on the surface of cells can actually switch on genes inside a cell's nucleus, thus promoting cancer development in two distinct ways.

Role of gene identified in development of tumours in children

Medical researchers from Children’s Cancer Institute Australia for Medical Research (CCIA) have made significant progress in understanding tumour initiation in the aggressive, debilitating childhood cancer, neuroblastoma

Childhood leukaemia significantly lower in Asia than in Western countries

The incidence of childhood leukaemia in Britain increased dramatically during the twentieth century. The increase has mainly affected the under-five age group, in whom the risk increased by more than 50 per cent during the second half of the century alone.

Experts consider evidence of link between the rise in childhood leukaemia and increased light at night

International experts will today consider the evidence for a link between the rise in childhood leukaemia and increased light at night at an international scientific conference in London.
