Women with non–invasive breast cancer carry the same mutations in two inherited breast/ovarian cancer genes as women diagnosed with invasive breast cancer

The inherited breast/ovarian cancer genes are BRCA1 and BRCA2, which are associated with an increased risk of breast and/or ovarian cancer. The results are part of a five–year study of a common form of early stage breast cancer called ductal carcinoma in situ (DCIS).

Scientists have identified a key network that prevents damage by oxygen radicals

Reactive oxygen species (ROS), or 'oxygen radicals', have been identified as major contributors to signs of premature aging, increased cancer prevalence linked to inflammation-associated syndromes and a variety of human diseases.

Mutations in newly discovered gene, NPHP5 cause Senior-Loken syndrome

Scientists at the University of Michigan Medical School have discovered a gene called NPHP5 and found mutations in this gene that cause a rare genetic disease called Senior-Loken syndrome. Children with this syndrome develop a type of cystic kidney disease called nephronophthisis, as well as a form of blindness called retinitis pigmentosa.

Discovery gives clinicians new targets for making existing therapies more effective and developing drugs to inhibit the growth of cancers

A team of researchers at the University of Alberta in Edmonton and the Samuel Lunenfeld Research Institute in Toronto have discovered how a key enzyme involved in repairing DNA is put together and how it works--a development that opens up new therapies for making cancer cells more vulnerable to attack.

Important advance in our understanding of colorectal cancer

An international team of medical scientists has made an important advance in our understanding of the second most fatal form of cancer in the industrialized world. Professor Jeremy R. Jass, who holds a Canada Research Chair in Gastrointestinal Pathology at McGill University in Montreal

Inherited traits and tumor mutations affect response to treatment of leukemia

The outcome of chemotherapy treatment for acute lymphoblastic leukemia (ALL) depends not only on the acquired genetic make-up of the leukemic cells, but on genes that children inherit from their parents. This study, from investigators at St. Jude Children's Research Hospital, is published in the online edition of Blood.

Researchers identify first known mutation to occur in lung cancer patients who have never smoked

Dr.Adi Gazdar, professor of pathology in the Nancy B. and Jake L. Hamon Center for Therapeutic Oncology Research and senior author of the study in today's issue of the Journal of the National Cancer Institute, explains that the findings may show why certain lung cancer patients respond dramatically to a specific form of targeted therapy while others have little or no response.

UK Government stockpiles anti-viral medicine Tamiflu from Roche

In an attempt to prevent the spread of the influenza pandemic birdflu the U.K. government will buy 200 million pounds ($384 million) worth of the anti-viral medicine Tamiflu from Roche, one of Switzerland's largest drug companies. The influenza pandemic could kill more than 50,000 people in the country.

Study describes the first known mutation to occur in lung cancer patients who have never smoked

Lung cancer patients who have never smoked are more likely than smokers to harbor one of two genetic mutations that researchers at UT Southwestern Medical Center have now linked to the disease.

Methylphenidate linked to chromosomal changes

In a small but startling preliminary new study, Texas researchers have found that after just three months, every one of a dozen children treated for attention deficit/hyperactivity disorder (ADHD) with the drug methylphenidate experienced a threefold increase in levels of chromosome abnormalities—occurrences associated with increased risks of cancer and other adverse health effects.

Scientists identify immune-system mutation

A team of Fox Chase Cancer Center scientists led by immunologist Dietmar J. Kappes, Ph.D., has identified the genetic mutation that keeps a mouse strain from developing white blood cells, or lymphocytes, called helper T cells. The report by Kappes and his colleagues appears in the Feb. 24 issue of Nature.

Early Alzheimer's disease may be precipitated by a neuron traffic jam

Early Alzheimer's disease may be precipitated by a “traffic jam” within neurons that causes swelling and prevents proper transport of proteins and structures in the cells, according to new studies by Howard Hughes Medical Institute researchers.
