Tomatoes may harbour cancer cure

Tomatoes may harbour cancer cureWashington, Aug 21 : Turning up the heat on red tomatoes while processing, can boost the garden staple’s disease-fighting power, say a group of researchers, who added that the effect may help fight cancer and other chronic diseases.

The research team found that turning up the heat while processing tomatoes increases the absorption of lycopene molecules found in the veggie, which are linked to the prevention of the deadly diseases.

Scientists identify cancer signatures

Scientists identify cancer signaturesWashington, Aug 16 : Researchers from Children''s Hospital Boston and Harvard University claim to have uncovered the trends in cancer gene expression in the developmental stages of various human tissues.

The team led by Isaac S Kohane performed a comprehensive comparison of genes expressed in early developmental stages of various human tissues and those expressed in different cancers affecting these tissues.

Nanotubes to deliver knockout punch to cancer sans side effects

Cancer CellsWashington, August 15: Stanford University researchers in the U. S. have devised a way to improve chemotherapy’s effectiveness against cancer, and reduce its side effects.

The researchers say that they have found out how to get a higher proportion of a given dose of medications into tumour cells, to avoid “spillovers” that can kill the healthy cells.

Breast cancer breakthrough may hold hopes for millions

Breast CancerLondon, Aug 13: Breast cancer patients have been given a new hope in the war against the deadly disease.

The British researchers have announced a dramatic progress in a technique, which can stop the growth of tumours.

According to the researchers, patients could soon benefit from a unique combination of drug treatments, which has proved highly successful in fighting cancer in trials on mice.

Switching off cancer comes closer to reality

Washington, August 9 : Australian scientists have found a novel way to inactivate a molecule called Gab2, a key player in the molecular processes that trigger breast cancer and certain forms of leukaemia.

Professor Roger Daly, a researcher at the Garvan Institute of Medical Research, points out that this molecule operates downstream of a major breast cancer oncogene, HER2, the target of the drug Herceptin.

He says that blocking signals to and from Gab2 may prevent it from fulfilling its role in cell proliferation.

Broccoli juice helps Brit beat bladder cancer!

London, July 21: A daily glass of broccoli juice can protect against bladder cancer, swears a 79-year old Brit who beat the disease by downing the drink everyday.

Ray Wiseman was diagnosed with bladder cancer five years ago, and survived the condition with just half a tumbler broccoli juice daily.

“If I’d had my bladder removed five years ago — as was suggested — I’d have been vulnerable to many infections and wouldn’t be here,” The Sun quoted him as saying.

“But the broccoli has stopped any spread of the cancer.

Scientists try to trace the history of cancer development

Washington, July 17: Weizmann Institute scientists have devised a way to reconstruct a cell’s ‘family tree’, and applied the technique to trace the history of the development of cancer.

The researchers say that they have thus far calculated the age of the tumour, and characterized its growth pattern.

They believe that cell lineage studies of cancer may someday lead them to the root of cancer.

Cancer survival varies widely between countries

London, July 17: A global analysis has shown that cancer survival rate varies widely among different countries

The worldwide analysis of 31 countries in 5 continents found that black men and women are less likely to survive cancer than white men and women in the United States.

The CONCORD study involved analysis of people suffering from cancers of the breast (women), colon, rectum and prostate.

The team found that the USA has the highest 5-year survival rate for prostate cancer.

How vitamin A promotes cancer growth

Washington, July 16: A new study from Georgetown University Medical Centre has found that vitamin A can push breast cancer cells to form blood vessel, thus promoting tumour growth in patients.

The researchers found that vitamin A, when applied to breast cancer cells, triggers genes that can push stem cells embedded in a tumour to morph into endothelial cells.

These cells can then build blood vessels to link up to the body''s blood supply, promoting further tumour growth.

Be active to reduce your chances of developing cancer

Melbourne, July 10 : Individuals who’re active physically are less likely to develop cancer than their sedentary counterparts, says a new research.

The study, led by the Japanese health ministry, surveyed around 80,000 men and women between the ages 45 to 74 living in nine Japanese prefectures.

The research found that the men in the most active group of people surveyed had 13 per cent less risk of developing cancer compared with the least active group, and women in the most active group had a 16 per cent lower risk than their sedentary counterparts.
