Cadmium exposure can cause progression of aggressive breast cancer

Studies by researchers at Dominican University of California show that breast cancer cells become increasingly aggressive the longer they are exposed to small concentrations of cadmium, a heavy metal commonly found in cosmetics, food, water and air particles.

Exposure to arsenic can turn normal stem cells into cancer stem cells

Researchers at the National Institutes of Health have discovered how exposure to arsenic can turn normal stem cells into cancer stem cells and spur tumor growth. Inorganic arsenic, which affects the drinking water of millions of people worldwide, has been previously shown to be a human carcinogen.

Metformin prevents primary liver cancer in animal models

Metformin, a drug widely used to treat Type II diabetes, may help to prevent primary liver cancer, researchers at the University of Maryland Marlene and Stewart Greenebaum Cancer Center report in the April 2012 issue of Cancer Prevention Research.

Study demonstrates molecular mechanisms of cadmium-induced prostate cancer

A recent study conducted at Marshall University may eventually help scientists develop new treatments for prostate cancer, the most common malignancy in American men.

Insight into relationship between two types of suppressors in cancerous tumors

The University of Kentucky has announced that Dr. Daret St. Clair, the James Graham Brown Endowed Chair and professor of toxicology, has published the first comprehensive study that provides insight into the relationship between two types of suppressors in cancerous tumors. The results will enhance the understanding of transcriptional mechanisms in carcinogenesis.

OGF-OGFr axis discovery provides new insights into ovarian cancer

Researchers at The Pennsylvania State University College of Medicine, Hershey, Pennsylvania have discovered that the presence and integrity of the opioid growth factor receptor (OGFr), which mediates the inhibitory action of opioid growth factor (OGF) on cell proliferation, is a key to understanding the progression and treatment of human ovarian cancer.

IKBKE protein plays two roles in tobacco-related NSCLC

Researchers at Moffitt Cancer Center in Tampa, Fla., have discovered that the immune response regulator IKBKE (serine/threonine kinase) plays two roles in tobacco-related non-small cell lung cancers. Tobacco carcinogens induce IKBKE and, in turn, IKBKE induces chemotherapy resistance.

Study shows grape seed extract kills head and neck squamous cell carcinoma cells

Nearly 12,000 people will die of head and neck cancer in the United States this year and worldwide cases will exceed half a million.

Cocoa can help prevent onset of colon carcinogenesis

A new study on living animals has shown for the first time that eating cocoa (the raw material in chocolate) can help to prevent intestinal complaints linked to oxidative stress, including colon carcinogenesis onset caused by chemical substances.

Exposure to metformin may decrease risk of cancer

In 2005, news first broke that researchers in Scotland found unexpectedly low rates of cancer among diabetics taking metformin, a drug commonly prescribed to patients with Type II diabetes. Many follow-up studies reported similar findings, some suggesting as much as a 50-per-cent reduction in risk.

Four or more coffees reduce risk of womb cancer

According to a new study drinking four or more cups of coffee a day may reduce risk of developing endometrial cancer or womb cancer by almost 25 per cent.

Silibinin stops spread of lung cancer in mice

Tissue with wound-like conditions allows tumors to grow and spread. In mouse lung cancer cells, treatment with silibinin, a major component of milk thistle, removed the molecular billboards that signal these wound-like conditions and so stopped the spread of these lung cancers, according to a recent study published in the journal Molecular Carcinogenesis.

Alcohol consumption in earlier and later adult life associated with increased risk of breast cancer

Consumption of 3 to 6 alcoholic drinks per week is associated with a small increase in the risk of breast cancer, and consumption in both earlier and later adult life is also associated with an increased risk, according to a study in the November 2 issue of JAMA.

AICR recommends intake of cancer-fighting foods

Colleen Spees has always been interested in the role that diet played in disease, and set her sights on a career where she would counsel patients and train future dietitians. With multiple family members diagnosed with various types of cancer, Colleen decided to make the transition from clinical professional and nutrition educator to research scientist.

University of Kentucky receives Department of Defense grant for lung cancer study

The University of Kentucky's Dr. Susanne Arnold and colleagues were awarded a grant by the Department of Defense to study potential environmental reasons for the high lung cancer rates in Eastern Kentucky.

Biologists identify mechanism of H. pylori that damages DNA of gastric mucosal cells

The stomach bacterium Helicobacter pylori is one of the biggest risk factors for the development of gastric cancer, the third most common cause of cancer-related deaths in the world.

Chromatin might have another life as direct signaling molecule

Chromatin - the intertwined histone proteins and DNA that make up chromosomes - constantly receives messages that pour in from a cell's intricate signaling networks: Turn that gene on. Stifle that one. But chromatin also talks back, scientists at The University of Texas MD Anderson Cancer Center report today in the journal Cell, issuing orders affecting a protein that has nothing to do with chromatin's central role in gene transcription - the first step in protein formation.

Largest ever molecular-genetic study of ependymomas of the cerebellum

Ependymomas are the second most frequent type of malignant brain tumor in children. Ependymoma develops from precursor cells of the tissue that lines the hollow cavities of the brain. Therapy results of ependymoma vary immensely: While in some patients tumor growth comes to a standstill after surgery and radiotherapy, in other children the disease rapidly takes a severe course.

Carcinogenesis is just another form of speciation, proposes new theory

Cancer patients may view their tumors as parasites taking over their bodies, but this is more than a metaphor for Peter Duesberg, a molecular and cell biology professor at the University of California, Berkeley.

Beta HPV prophylactic strategies may have a positive impact on prevention of NMSC

Non-melanoma skin cancer is the most common form of malignancy in adult Caucasian populations, with more than a million cases recorded each year in the USA alone.
