Dr Rafat Siddiqui, from the Methodist Research Institute and Indiana University in Indianapolis, and his colleagues studied the effect of two Omega-3 fatty acids, docosahexaenoic acid ( DHA ) and eicosapentaenoic acid ( EPA ), combined with propofol on a breast cancer cell line in vitro. Omega-3 fatty acids such as DHA and EPA have a minimal effect on cancer cells when applied alone. Propofol is a potent anti-oxidant known to inhibit cancer cell migration by only 5-10%.

The results of the study show that propofol and DHA or EPA have a much more significant effect on cancer cells when used in combination, as conjugates, than when used alone. The conjugates inhibit cancer cell adhesion by 15% and 30% respectively, reduce cell migration by 50% and increase apoptosis by 40%.

"These results suggest that the novel propofol-DHA and propofol-EPA conjugates reported here may be useful for the treatment of breast cancer" conclude Siddiqui and colleagues.

Malignant cancer cells are highly invasive cells that have lost the ability to sense cues from their environment. As a result, they start dividing abnormally, migrate and accumulate into malignant tumours, in a process called metastasis, which is potentially life-threatening. The aim of anti-cancer drugs is therefore to prevent the cells from dividing abnormally and from spreading, to kill the cells, or to cause the cells to kill themselves.

Fatty acids are often attached to drugs, because they facilitate the absorption of the drugs by the cells. Siddiqui and colleagues explain that DHA and EPA might have had this effect on propofol. They add "It is possible that these conjugates provide a mechanism whereby propofol can be retained in cell membranes for a longer duration and therefore enhance its anticancer effects".

Omega-3 fatty acids, like those found in oily fish such as tuna, salmon, herring, sardines and mackerel, are already known to have many positive health benefits. They are commonly recommended for maintaining a healthy heart, as they are known to reduce cholesterol levels and thought to help prevent cardiovascular disease. Research suggests that Omega-3 may also protect against arthritis, lupus, and asthma and help people with biopolar disorder.

About the author:Mike Adams (aka the "Health Ranger") is a best selling author (#1 best selling science book on Amazon.com) and a globally recognized scientific researcher in clean foods. He serves as the founding editor of NaturalNews.com and the lab science director of an internationally accredited (ISO 17025) analytical laboratory known as CWC Labs. There, he was awarded a Certificate of Excellence for achieving extremely high accuracy in the analysis of toxic elements in unknown water samples using ICP-MS instrumentation. Adams is also highly proficient in running liquid chromatography, ion chromatography and mass spectrometry time-of-flight analytical instrumentation.

Adams is a person of color whose ancestors include Africans and Native American Indians. He's also of Native American heritage, which he credits as inspiring his "Health Ranger" passion for protecting life and nature against the destruction caused by chemicals, heavy metals and other forms of pollution.

Adams is the founder and publisher of the open source science journal Natural Science Journal, the author of numerous peer-reviewed science papers published by the journal, and the author of the world's first book that published ICP-MS heavy metals analysis results for foods, dietary supplements, pet food, spices and fast food. The book is entitled Food Forensics and is published by BenBella Books.

In his laboratory research, Adams has made numerous food safety breakthroughs such as revealing rice protein products imported from Asia to be contaminated with toxic heavy metals like lead, cadmium and tungsten. Adams was the first food science researcher to document high levels of tungsten in superfoods. He also discovered over 11 ppm lead in imported mangosteen powder, and led an industry-wide voluntary agreement to limit heavy metals in rice protein products.

In addition to his lab work, Adams is also the (non-paid) executive director of the non-profit Consumer Wellness Center (CWC), an organization that redirects 100% of its donations receipts to grant programs that teach children and women how to grow their own food or vastly improve their nutrition. Through the non-profit CWC, Adams also launched Nutrition Rescue, a program that donates essential vitamins to people in need. Click here to see some of the CWC success stories.

With a background in science and software technology, Adams is the original founder of the email newsletter technology company known as Arial Software. Using his technical experience combined with his love for natural health, Adams developed and deployed the content management system currently driving NaturalNews.com. He also engineered the high-level statistical algorithms that power SCIENCE.naturalnews.com, a massive research resource featuring over 10 million scientific studies.

Adams is well known for his incredibly popular consumer activism video blowing the lid on fake blueberries used throughout the food supply. He has also exposed "strange fibers" found in Chicken McNuggets, fake academic credentials of so-called health "gurus," dangerous "detox" products imported as battery acid and sold for oral consumption, fake acai berry scams, the California raw milk raids, the vaccine research fraud revealed by industry whistleblowers and many other topics.

Adams has also helped defend the rights of home gardeners and protect the medical freedom rights of parents. Adams is widely recognized to have made a remarkable global impact on issues like GMOs, vaccines, nutrition therapies, human consciousness.

In addition to his activism, Adams is an accomplished musician who has released over a dozen popular songs covering a variety of activism topics.
