Mayo-led study finds smoking related to subset of colorectal cancers
Smoking puts older women at significant risk for loss of DNA repair proteins that are critical for defending against development of some colorectal cancers, according to research from a team led by Mayo Clinic scientists.

OHSU Cancer Institute researchers find connection between protein, prognosis in breast cancer
Oregon Health & Science University Cancer Institute researchers have found that a tumor protein present in an aggressive form of breast cancer is related to a poor prognosis.

Exercise may lead to faster prostate tumor growth
Prostate tumors grew more quickly in mice who exercised than in those who did not, leading to speculation that exercise may increase blood flow to tumors, according to a new study by researchers in the Duke Comprehensive Cancer Center and the Duke Prostate Center.

Penn researchers find targeted therapy combination overcomes treatment resistance in liver cancer
Researchers at the University of Pennsylvania School of Medicine and Abramson Cancer Center reported today at the annual meeting of the American Association for Cancer Research that combining two targeted therapies overcomes treatment resistance in liver cancer cell lines.

Vitamin D and calcium influence cell death in the colon, researchers find
Researchers at Emory University are learning how vitamins and minerals in the diet can stimulate or prevent the appearance of colon cancer.

In lab study, researchers find molecule that disrupts Ewing's sarcoma oncogene
Researchers at Georgetown University Medical Center have found a small molecule they say can block the action of the oncogene that causes Ewing's sarcoma, a rare cancer found in children and young adults.

Mouth may tell the tale of lung damage caused by smoking
Cells lining the mouth reflect the molecular damage that smoking does to the lining of the lungs, researchers at the University of Texas M.

Insects evolved radically different strategy to smell
Researchers at Rockefeller University and the University of Tokyo have joined forces to reveal that insects have adopted a strategy to detect odors that is radically different from those of other organisms -- an unexpected and controversial finding that may dissolve a dominant ideology in the field.

Kids with autism may have gene that causes muscle weakness
Some kids with autism may have a genetic defect that affects the muscles, according to research that will be presented at the American Academy of Neurology 60th Anniversary Annual Meeting in Chicago, April 12-19, 2008.

Jefferson scientists' discovery may help explain smoking-pancreatic cancer link
If lung cancer and heart disease aren't enough, cigarette smokers are also at higher risk for developing, among other things, pancreatic cancer.

Largest ever study of genetics of common disease just got bigger
DNA samples from 120,000 people are to be analysed in a £30 million follow up to last year's Wellcome Trust Case Control Consortium, the largest ever study of the genetics behind common diseases.

Older Australians at risk of sun-related skin cancer death
A new Western Australian study has revealed the mortality from nonmelanoma skin cancer, commonly considered less dangerous than melanoma, is affecting older Australians at a worrying rate.

Biomarkers allow doctors to match therapy to patient
Genetic variations ensure that no two people are exactly alike, nor are their cancers.

Stopping unwanted cell death: Implications for drug discovery
Researchers have established necrostatins as the first-in-class inhibitors of RIP1 kinase, a protein that can direct cells into necrotic death.

How what and how much we eat (and drink) affects our risk of cancer
A healthy diet and lifestyle protect against a wide range of diseases, and new research presented at the American Association for Cancer Research 2008 Annual Meeting, April 12-16, shows that cancer is no exception.

A genetic cause for iron deficiency
The discovery of a gene for a rare form of inherited iron deficiency may provide clues to iron deficiency in the general population -- particularly iron deficiency that doesn't respond to iron supplements -- and suggests a new treatment approach.
