Washington, Sept 15 (ANI): In a novel study, scientists from University of North Carolina and the College of Arts and Sciences have identified a novel mechanism that triggers blood vessel growth.

They have found that vascular networks form and expand by “sprouting” similar to the way trees grow new branches.

The process allows fresh [...]

London, Sep 14 (ANI): British scientists have identified the master gene, called E4bp4, that causes blood stem cells to turn into disease-fighting ‘Natural Killer’ (NK) immune cells.

The discovery, by researchers at Imperial College London, UCL and the Medical Research Council’s National Institute for Medical Research, could one day help scientists boost the body’s production of [...]

London, Sept 14 (ANI): Having a second child within a year of the first birth can increase a woman’s risk of developing breast cancer, finds a new study.

The research, involving 30,000 women each of whom had produced five or more children, has shown that those with a gap of less than 12 month were 5.2 [...]

Washington, Sept 13 (ANI): Controlling pain and discomfort arising from cancer treatment can speed up recovery for children battling the disease, say researchers.

Experts at St. Jude Children’s Research Hospital suggest that tumours press on nerves, bones and organs; radiation can damage the skin and mucus membranes; and chemotherapy agents can cause harsh side effects.

Moreover, [...]

Washington, Sep 9 (ANI): A lung cancer oncogene, called PKCiota, is necessary for the proliferation of lung cancer stem cells, and turning it off could act as a key for the treatment of this deadly disease, according to scientists at the Mayo Clinic campus in Florida.

These stem cells are rare and powerful master cells that [...]

Washington, Sept 8 (ANI): A simple jab may soon help prevent prostate cancer, say researchers.

The research team from University of Utah and University of Columbia have identified a virus, known to trigger leukaemia, in malignant human prostate cancer cells.

The research team hopes that the virus, XMRV (Xenotropic murine leukemia virus-related virus), would open opportunities [...]

Washington, September 4 (ANI): American scientists have discovered a protein’s “Jekyll and Hyde” role in cancer development.

While the protein called FOXO3a is thought to protect against cancer development, researchers from [...]

Washington, September 2 (ANI): Johns Hopkins engineers have come up with a new computational method that can help scientists to sift through hundreds of genetic mutations to highlight the DNA changes that are most likely to promote cancer.

The computational method is called CHASM, short for Cancer-specific High-throughput Annotation of Somatic Mutations.

According to its inventors, the [...]

Washington, Aug 27 (ANI): Scientists in Switzerland have discovered a novel way to inhibit the growth of human colon cancer cells and preventing the disease from reaching advanced stages and the development of liver metastases.

The study shows that blocking the so-called Hedgehog-GLI pathway can prevent the growth of tumours, metastatic lesions and cancer stem cells, [...]

London, Aug 25 (ANI): British scientists have made a major breakthrough in search of a cure for breast cancer, and may develop a drug within two years to beat the life threatening disease.

Instead of looking at how [...]

Melbourne, Aug 24 (ANI): A team of Australian scientists has genetically modified human embryonic stem cells to glow red when they develop into premature red blood cells.

The breakthrough is seen as the next step in producing artificial blood.

Dr Andrew Elefanty at Monash University in Melbourne and his colleagues inserted specific genes that code for colour, [...]

Washington, Aug 14 (ANI): A new study, led by an Indian-origin scientist, has shown that obesity increases risk of prostate cancer recurrence for both blacks and whites.

Study’s lead author Jayakrishnan Jayachandran, M.D. a urologic oncology fellow at Prostate Medical Center, and colleagues examined the records of 1,415 men enrolled in the Shared Equal Access Regional [...]

Washington, August 14 (ANI): An Indian-origin researcher in Boston has announced the discovery of a chemical that works in mice to kill the rare, but aggressive, cells within breast that have the ability to seed new tumours.

Piyush Gupta, a researcher at the Broad Institute, points out that these cells, known as cancer stem cells, are [...]

Washington, Aug 13(ANI): American golfer Tiger Woods’ pursuit to win his third consecutive tournament and his first major of 2009 was hit by an injury scare while practicing at Hazeltine.

Woods, a four-time US PGA Championships winner, is 13-8 favourite with bookmakers to equal the record held jointly by Jack Nicklaus and Walter Hagen, who [...]

Washington, Aug 12 (ANI): Taking aspirin on a regular basis after being diagnosed with colon cancer has been found to reduce the chances of dying from the disease, reveals a new study.

Numerous prospective, observational studies have shown that regular aspirin use is linked to a lower risk of colorectal adenoma (a benign tumour) or cancer. [...]

London, Aug 11 (ANI): Scientists from University of Virginia have developed new light-emitting biomaterial that could improve tumour imaging.

The new material is an oxygen nanosensor that couples a light-emitting dye with a biopolymer and simplifies the imaging of oxygen-deficient regions of tumours. [...]

Washington, August 11 (ANI): Scientists at the University of Wisconsin-Madison have moved a step closer to transforming embryonic stem cells into a multipurpose medical tool, for they have successfully transformed these versatile cells into progenitors of white blood cells and into six types of mature white blood and immune cells.

The researchers agree that a clinical [...]

Washington, August 11 (ANI): A team of Thomas Jefferson University researchers in the U.S. have identified eight risk factors to predict whether a choroidal nevus-a benign, flat, pigmented growth inside the eye and beneath the retina-may develop into melanoma.

“There is strong interest for early detection of choroidal melanoma [a malignant growth], and its differentiation from [...]

Washington, August 10 (ANI): A new review suggests that limb-sparing surgery may not provide a bone cancer patient with a better quality of life than amputation.

Published in the journal Cancer, the analysis indicates that patients and physicians should rethink the pros and cons of limb-sparing surgery and amputation.

Patients with tumours of the bone or [...]

Washington, August 9 (ANI): Scientists in America have announced two significant advances in treating lung cancer.

Dr. Glen Weiss, from the Translational Genomics Research Institute (TGen) and Scottsdale Healthcare, made the announcements at the 13th World Conference on Lung Cancer in San Francisco.

The researcher is hopeful that the new findings will eventually help prevent lung [...]
