Increase in Vitamin E tied to fewer in utero deaths

Manipulating the in utero environment may alter the onset of cancers that appear later in the lives of mammals, according to a new University of Toronto study published in the journal Carcinogenesis.

C-reactive protein helps identify progressive precancerous lesions in the lung

C-reactive protein (CRP), a biomarker for inflammation in the blood, can help to identify individuals whose abnormal precancerous lesions will advance closer to invasive lung cancer.

Oddly shaped DNA can cause DNA breaks in mammalian cells

When otherwise normal DNA adopts an unusual shape called Z-DNA, it can lead to the kind of genetic instability associated with cancers such as leukemia and lymphoma, according to a study by researchers at The University of Texas M. D. Anderson Cancer Center.

Vitamin D could provide beneficial treatment to prostate cancer

Vitamin D can inhibit the spread of prostate cancer cells by limiting the activity of two specific enzymes, University of Rochester Medical Center scientists report.

FDA affirms safety of Aspartame

The Calorie Control Council has stated that a rat study conducted by Italy's Ramazzini Institute is totally contradictory to the extensive scientific research and regulatory reviews conducted on aspartame. The U.S. Food & Drug Administration (FDA) has said they are not recommending any changes in the use of aspartame.

Scientists have determined the detailed structure of an essential piece of the telomerase enzyme

Scientists have determined the detailed structure of an essential piece of the telomerase enzyme, an important contributor to the vast majority of human cancers. Understanding the physical shape of the protein has led to a better understanding of how it acts to immortalize cells - and should help scientists design broadly effective cancer drugs.

Exploiting biology's own chemical toolbox...

Exploiting biology's own chemical toolbox, researchers have developed a new technique that will allow them to modify specific sequences within a DNA molecule. The approach will not only help reveal the impact of biochemical alterations to DNA, but could have far-reaching implications for DNA-based medical diagnosis and nanobiotechnology.

Cellular clues to vitamin A resistance in lung cancer

Vitamin A deficiency has been associated with the development of lung cancer in laboratory studies. However, clinical trials of natural and synthetic derivatives of vitamin A, called retinoids, for the prevention of lung cancer have been largely unsuccessful in the general population.

Gene found only in men is altered by a chemical process, which is in turn linked to aggressive forms of melanoma

New scientific evidence that may shed light on why men are more likely than women to develop aggressive forms of skin cancer has been published in Carcinogenesis.

Gene B-myb essential in preventing tumors

A new study has confirmed that research done with zebrafish may be able to play a critical role in learning about the genetic basis of cancer and the mutations that can lead to it - and identified one gene in particular, B-myb, whose function is essential to preventing tumors.

African-American women with mitochondrial DNA variant are at increased risk of breast cancer

African-American women who carry the 10398A mitochondrial DNA allele are 60 percent more likely to develop invasive breast cancer than African-American females without that genetic marker, according to research published in the September 1 issue of "Cancer Research."

MiRNA is opening up a whole new way of understanding carcinogenesis

Scientists mining vast, largely unexplored regions of the human genome have identified a small handful of mini-molecules that play a major role in the development of cancer and perhaps many other diseases.

Omega-6 fatty acids promote the growth of prostate tumor cells in the laboratory

A study conducted at the San Francisco VA Medical Center (SFVAMC) has demonstrated that omega-6 fatty acids such as the fat found in corn oil promote the growth of prostate tumor cells in the laboratory.

$4.7million grant for research on neuroblastoma

Significant funding from Australia's National Health and Medical Research Council will enable researchers at Children’s Cancer Institute Australia (CCIA) for Medical Research to make progress on the treatment of one the most aggressive, drug-resistant childhood cancers - neuroblastoma - over the next five years.

Studies explore genetic interactions between two well-known tumor suppressor proteins, PTEN and TSC2

Two papers in the August 1 issue of Genes & Development explore the genetic interactions between two well-known tumor suppressor proteins, PTEN and TSC2.

Detection levels of deadly form of melanoma remains the same

Despite campaigns promoting early detection and increased awareness of melanoma (skin cancer) the proportion of the most aggressive and deadly form of melanoma remains the same, according to an article in the June issue of Archives of Dermatology, one of the JAMA/Archives journals.

Incorporating human papillomavirus testing into cervical cancer screening will provide health benefits at a reasonable cost

Incorporating testing for human papillomavirus (HPV) DNA into cervical cancer screening has the potential for improving health benefits at a reasonable cost in France, Italy, the Netherlands, and the United Kingdom, according to a new study in the June 15 issue of the Journal of the National Cancer Institute.

Harmful chemicals may reprogram gene response to estrogen

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.

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.
