Atmospheric oxygen may play role in lung carcinogenesis, new study suggests

The ancient physician/alchemist, Paracelsus, said: "The dose makes the poison." According to a new study published in PeerJ, even oxygen may fall prey to the above adage. While essential to human life, aspects of oxygen metabolism may promote cancer. Capitalizing on the inverse relationship of oxygen concentration with elevation, researchers found lower rates of lung cancer at higher elevations, a trend that did not extend to non-respiratory cancers, suggesting that carcinogen exposure occurs via inhalation.

Researchers identify mutations that destabilize DNA structure that turns a gene off

Researchers at the University of Louisville's James Graham Brown Cancer Center have identified for the first time mutations that destabilize a DNA structure that turns a gene off. These mutations occur at four specific sites in what is known as the "hTERT promoter" in more than 75 percent of glioblastomas and melanomas.

SIRT6 protein inhibits liver and colon cancers, but promotes skin cancer caused by ultraviolet light

A new study published in Cancer Research shows SIRT6—a protein known to inhibit the growth of liver and colon cancers—can promote the development of skin cancers by turning on an enzyme that increases inflammation, proliferation and survival of sun-damaged skin cells.

Sequencing the Asian liver fluke genome: an interview with Dr Neil Young

Opisthorchis viverrini is a parasitic flatworm (or liver fluke) endemic throughout Thailand, the Lao People’s Democratic Republic, Vietnam and Cambodia. Humans are infected with this parasite when they eat a fluke encysted in inadequately cooked/preserved freshwater fish.

Study shows new role for protein APC in suppressing colorectal cancer

A study recently published in the journal Carcinogenesis by researchers at the University of Kansas shows a new role for the protein adenomatous polyposis coli (APC) in suppressing colorectal cancer - the second-leading cause of cancer-related deaths in the U.S.

Viewpoints: Va. GOP's 'Medicaid charade'; Paul Ryan's health Rx for poverty; giving the sick unapproved drugs

Virginia lawmakers will convene in a special session next month to address the question of expanding Medicaid and, more broadly, the fact that hundreds of thousands of poor and disabled people in the state have no health insurance coverage. Democrats and some moderate Republicans have advanced a variety of ideas to tackle that problem. Conservative Republicans, who control the legislature in Richmond, have rejected those solutions while proposing no alternative. Does the GOP intend for the special session to be anything more than a charade at taxpayers' expense? (8/15).

Chemoprevention and colon cancer: an interview with Dr. John Letterio, Case Western Reserve University School of Medicine

The basic idea of cancer chemoprevention is to arrest or reverse the progression of premalignant cells towards full malignancy, using physiological mechanisms that do not kill healthy cells.

Research finding paves way for targeted approaches to treating cancer patients

Twelve years ago, UNC School of Medicine researcher Brian Strahl, PhD, found that a protein called Set2 plays a role in how yeast genes are expressed - specifically how DNA gets transcribed into messenger RNA. Now his lab has found that Set2 is also a major player in DNA repair, a complicated and crucial process that can lead to the development of cancer cells if the repair goes wrong.

Gene regulation responsible for normal breast tissue may also play role in cancer development

About one in eight women in the United States will contract breast cancer in her lifetime. Now new research from Tel Aviv University-affiliated researchers, in collaboration with Johns Hopkins University, has provided another tool to help women, clinicians, and scientists searching for a cure to the one of the most widespread yet incurable diseases on the planet.

Biologists show bioelectrical signals control tumors arising from cancer-causing genes, fatty acid

Developmental biologists at Tufts University, using a tadpole model, have shown that bioelectrical signals from distant cells control the incidence of tumors arising from cancer-causing genes and that this process is impacted by levels of a common fatty acid produced by bacteria found in the tadpole and also in humans.
