Natural (born) killer cells battle pediatric leukemia
Researchers at Children's Hospital Los Angeles have shown that a select team of immune-system cells can be multiplied in the lab, creating an army of natural killer cells that can be used to destroy leukemia cells.

Deaths rise with shift from in-hospital to outpatient procedures for urology surgeries
As hospitals have shifted an array of common urological surgeries from inpatient procedures to outpatient, potentially preventable deaths have increased following complications. Those were the primary findings of a new study led by Henry Ford Hospital researchers, who initially expected that improved mortality rates recently documented for surgery overall would also translate to commonly performed urologic surgeries. The opposite turned out to be true.

Extended support helps patients stay smoke-free after hospital discharge
A Massachusetts General Hospital study in the Aug. 20 issue of JAMA describes a program that increased the proportion of hospitalized smokers who successfully quit smoking after discharge by more than 70 percent. The system used interactive voice response technology to provide support and stop-smoking medication for three months after smokers left the hospital.

WSU researchers find crucial step in DNA repair
Scientists at Washington State University have identified a crucial step in DNA repair that could lead to targeted gene therapy for hereditary diseases such as 'children of the moon' and a common form of colon cancer. Such disorders are caused by faulty DNA repair systems that increase the risk for cancer and other conditions.

Older patients with limited life expectancy still receiving cancer screenings
A substantial number of older patients with limited life expectancy continue to receive routine screenings for prostate, breast, cervical and colorectal cancer although the procedures are unlikely to benefit them.

Myc inhibition is an effective therapeutic strategy against most aggressive brain tumors
The Myc protein plays a key role in the development of several tumor types and its inhibition could therefore prove an effective therapy against many different cancers. Previous studies by this same VHIO group successfully blocked Myc through expression of an inhibitor, resulting in the eradication of lung tumors in preclinical models.

New mouse model points to therapy for liver disease
In a paper published online in Cancer Cell, scientists at the University of California, San Diego School of Medicine describe a novel mouse model that closely resembles human NASH and use it to demonstrate that interference with a key inflammatory protein inhibits both the development of NASH and its progression to liver cancer.

Microchip reveals how tumor cells transition to invasion
A microscopic obstacle course of carefully spaced pillars enables researchers to observe cancer cells directly as they break away from a tumor mass and move more rapidly across the microchip. The device could be useful for testing cancer drugs and further research on the mechanics of metastasis. A paper describing research using the device is published in Nature Materials.

A shift in the code: New method reveals hidden genetic landscape
With three billion letters in the human genome, it seems hard to believe that adding or removing a base could have much of an effect on our health. Yet, such insertions and deletions can dramatically alter biological function. It is has been difficult to detect these mutations. Cold Spring Harbor Laboratory scientists have devised a new way to analyze genome sequences that pinpoints insertions and deletions in people with diseases such as autism, obsessive compulsive disorder, and Tourette syndrome.

NSAIDs benefit overweight breast cancer patients, study finds
Researchers have determined that postmenopausal overweight or obese breast cancer patients receiving hormone therapy as part of their treatment and who use nonsteroidal anti-inflammatory drugs such as aspirin or ibuprofen have significantly lower breast cancer recurrence rates and a sizable delay in time to cancer recurrence.

Aspirin may slow recurrence in breast cancer patients
New findings published in the journal Cancer Research reveal some postmenopausal overweight breast cancer patients who use anti-inflammatory drugs like aspirin or ibuprofen have significantly lower breast cancer recurrence rates. Anti-inflammatory use reduced the recurrence of ERα positive breast cancer by 50 percent and extended patients' disease-free period by more than two years. Research was performed at the Cancer Therapy & Research Center at the University of Texas Health Science Center San Antonio and University of Texas Austin.

Protein found to block benefits of vitamin A cancer therapy
Retinoic acid is a form of vitamin A that is used to treat and help prevent the recurrence of a variety of cancers, but for some patients the drug is not effective. The reason for this resistance was unclear until this week when researchers from Virginia Commonwealth University Massey Cancer Center demonstrated that a protein known as AEG-1 blocks the effects of retinoic acid in leukemia and liver cancer.

Immune cell discovery could help to halt cancer spread
Melbourne researchers have revealed the critical importance of highly specialized immune cells, called natural killer cells, in killing melanoma cells that have spread to the lungs. These natural killer cells could be harnessed to hunt down and kill cancers that have spread in the body. The team, from the Walter and Eliza Hall Institute, also found natural killer cells were critical to the body's rejection of donor bone marrow transplants and in the runaway immune response during toxic shock syndrome.
