Plant oil suppresses viability of human prostate cancer cells

"This line of work dates back to the 1980s when the University of Wisconsin groups led by Drs. Charles Elson and Michael Gould discovered the anti-tumor activity of monoterpenes and soon after, sesqui- and di-terpenes." said Dr. Huanbiao Mo, senior author and professor in the Department of Nutrition and Food Sciences. These compounds, widely present in fruits, vegetables and grains, were found to be much more effective in suppressing the growth of tumor cells than that of normal cells. …

Oxygen – key to most life – decelerates many cancer tumors when combined with radiation therapy

In research examining tissue oxygenation levels and predicting radiation response, UT Southwestern scientists led by Dr. Ralph Mason reported in the June 27 online issue of Magnetic Resonance in Medicine that countering hypoxic and aggressive tumors with an "oxygen challenge" — inhaling oxygen while monitoring tumor response — coincides with a greater delay in tumor growth in an irradiated animal model…

Chemical probe confirms that body makes its own rotten egg gas, H2S, to benefit health

Hydrogen sulfide, or H2S, is normally toxic, but in small amounts it plays a role in cardiovascular health. In the new study, chemists developed a chemical probe that reacts and lights up when live human cells generate hydrogen sulfide, says chemist Alexander R. Lippert, Southern Methodist University, Dallas…

Komen breast cancer charity cancels walks in 7 US cities

Breast cancer charity Susan G. Komen for the Cure, which suffered a publicity backlash last year after it sought to cut funding to Planned Parenthood, said on Tuesday it was canceling fundraising walks next year in seven cities where money goals have not been met. The organization, which says it is the largest non-government funder of breast cancer research, said it was cutting three-day walks for 2014 in Phoenix, Boston, Chicago, Cleveland, Tampa Bay, San Francisco and Washington. The event will continue in seven other places. “The difficult decision to exit these markets was not made lightly, as we know this bold and empowering event has touched the lives of thousands of participants like you,” the Dallas-based group said in a message on its Facebook page. A Komen spokeswoman said in an email that participation in the three-day walks declined by 37 percent in the past four years, without specifying whether that was the number of participants or dollars raised. The group decided to remove the cities from next year's schedule that have not been meeting fundraising goals, the spokeswoman said. It was unclear what the group's fundraising targets were for the walks. Each participant is required to raise a minimum of $2,300 and walks about 60 miles over the three days. The charity sparked an outcry last year when it said it would cut funding to Planned Parenthood, a provider of birth control, abortion and other women's health services. Komen, which supports Planned Parenthood's efforts to provide access to breast-cancer screening, reversed that decision within days and said it would restore the funding. After the controversy, several of the group's leaders stepped down, and the group's founder, Nancy Brinker, stepped down as CEO, though she continued to hold a management role. Brinker founded the organization in 1982, two years after her sister, Susan G. Komen, died of breast cancer. Komen's signature event is the Race for the Cure, which includes 5 kilometers and marathon races as well as the walks. The group says the events involve more than 1.7 million participants each year. Komen will continue to hold walks in Atlanta, Dallas/Fort Worth, Michigan, Philadelphia, San Diego, Seattle and Minneapolis-St. Paul.source : http://www.foxnews.com/health/2013/06/05/komen-breast-cancer-charity-cancels-walks-in-7-us-cities/

Small molecule could have big impact on cancer

In a study published online May 28 in the journal Nature Communications, Ahn and his colleagues at UT Southwestern Medical Center describe the rational design of the molecule, as well as laboratory tests that show its effectiveness at blocking the cancer-promoting function of proteins called androgen receptors. Androgen receptors are found inside cells and have complex surfaces with multiple "docking points" where various proteins can bind to the receptor. …

Mapping the embryonic epigenome: How genes are turned on and off during early human development

After an egg has been fertilized, it divides repeatedly to give rise to every cell in the human body — from the patrolling immune cell to the pulsing neuron. Each functionally distinct generation of cells subsequently differentiates itself from its predecessors in the developing embryo by expressing only a selection of its full complement of genes, while actively suppressing others…
