Can inhaled oxygen cause cancer?
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.

Potentially targetable signaling pathway generates slowly proliferating, chemo-resistant cancer cells
A signaling pathway responsible for the generation of slowly proliferating cancer cells, which are hard to eradicate with current treatments and thought to be a cause of subsequent disease relapse, has been reported in a Rapid Impact study published in Molecular Cancer Research, a journal of the American Association for Cancer Research.

'Survival' protein a target in drug-resistant non-Hodgkin lymphomas
Melbourne researchers have discovered that targeting a cell 'survival' protein could help treat some lymphomas, including those cancers with genetic defects that make them resistant to many existing therapies.

Researchers identify new gene mutations linked to colorectal cancer in African-Americans
Case Comprehensive Cancer Center researchers have identified new gene mutations unique to colon cancers in African Americans -- the population with the highest incidence and death rates of any group for this disease. This discovery -- namely, that colorectal cancers appear different on a molecular level in African-Americans -- offers new hope for these patients. With this groundbreaking knowledge, scientists now will seek to develop treatments to target the distinct nature of the disease in African-Americans.

Beyond prevention: Sulforaphane may find possible use for cancer therapy

Moffitt researchers discover mechanism leading to drug resistance, metastasis in melanoma
Moffitt Cancer Center researchers have discovered a mechanism that leads to resistance to targeted therapy in melanoma patients and are investigating strategies to counteract it. Targeted biological therapy can reduce toxicity and improve outcomes for many cancer patients, when compared to the adverse effects of standard chemotherapeutic drugs. However, patients often develop resistance to these targeted therapies, resulting in more aggressive cells that can spread to other sites or cause regrowth of primary tumors.

CNIO researchers discover 1 of the genetic pieces of bladder cancer
Notch genes protect against bladder cancer, whilst in other tumors they act as oncogenes. Researchers warn that drugs that deactivate Notch in a non-specific manner could increase the risk of developing bladder cancer. Bladder cancer is the fifth most frequent cancer among men in developed countries.

From sexual dysfunction to anxiety, many cancer survivors struggle with post treatment
Even decades after being cured, many cancer survivors face physical and mental challenges resulting from their disease and its treatment. From physical problems such as sexual dysfunction to anxiety about getting cancer again survivors continue to fight long after the actual disease is defeated. That's the conclusion of a study led by University of Central Florida social work professor Mary Ann Burg.

Researchers discover new therapeutic target for treatment of acute myeloid leukemia
A study by the Cancer Science Institute of Singapore at the National University of Singapore has found new interactions between two molecules involved in acute myeloid leukemia (AML), STAT3 and PRL-3, which may offer a new therapeutic target for cancer treatment. The scientists discovered that STAT3, a molecule which has the potential to cause cancer, associates with and regulates the levels of PRL-3, a gene which has been implicated in various types of cancers.

Mayo researchers find cancer biopsies do not promote cancer spread
A study of more than 2,000 patients by researchers at Mayo Clinic's campus in Jacksonville, Fla., has dispelled the myth that cancer biopsies cause cancer to spread. In the Jan. 9 online issue of Gut, they show that patients who received a biopsy had a better outcome and longer survival than patients who did not have a biopsy.

New study findings help physicians and patients determine prostate cancer risk
A discovery by researchers at Huntsman Cancer Institute shows that looking at whether a man's uncles and great-grandparents, among other second- and third-degree relatives, had prostate cancer could be as important as looking at whether his father had prostate cancer. A more complete family history would give physicians a new tool to decide whether or not a prostate-specific antigen test was appropriate.

Scientists illuminate mysterious molecular mechanism powering cells in most forms of life
A team led by structural biologists at The Scripps Research Institute has taken a big step toward understanding the intricate molecular mechanism of a metabolic enzyme produced in most forms of life on Earth. The finding concerns nicotinamide nucleotide transhydrogenase, an ancient evolutionary enzyme that is part of a process key to maintaining healthy cells and has also recently been linked to diseases such as diabetes and cancer.

Blood vessel lining cells control metastasis
Scientists from the German Cancer Research Center in Heidelberg and from the Medical Faculty Mannheim of Heidelberg University paved the way for an innovative combination therapy against metastases: They treated mice with a combination of a low-dose metronomic chemotherapy and an antibody against Ang-2, a regulatory protein of the blood vessel lining cells. The treated animals had significantly less metastases.

Candice C. Black, D.O., explained how her team confirmed the utility of ProExC, an existing antibody cocktail commonly used for pathology tests of the uterine cervix.
