Study looks at cardiometabolic risk, schizophrenia and antipsychotic treatment
The duration of psychiatric illness and treatment for patients after first-episode schizophrenia spectrum disorders appears to be associated with being fatter and having other cardiometabolic abnormalities.

Patient's dramatic response and resistance to cancer drug traced to unsuspected mutations
Patients with lethal thyroid cancer experienced response for 18 months on clinical trial of everolimus. Sequencing of the tumor before and after trials yielded information on why tumor responded to and eventually resisted treatment, identifying mutations that may help guide treatment of patients with cancers with similar mutations.

Fruit flies reveal features of human intestinal cancer
Researchers in Spain have determined how a transcription factor known as Mirror regulates tumor-like growth in the intestines of fruit flies. The scientists believe a related system may be at work in humans during the progression of colorectal cancer due to the observation of similar genes and genetic interactions in cultured colorectal cancer cells. The results are reported in the journal EMBO Reports.

Circulating tumor cells provide genomic snapshot of breast cancer
Tumor cells isolated from the blood of patients with triple negative breast cancer reveal similar cancer-driving mutations as those detected from standard biopsy, suggesting that circulating cells could one day replace tissue biopsies.

Testosterone promotes prostate cancer in rats

The 'cyberwar' against cancer gets a boost from intelligent nanocarriers
Cancer possesses special traits for cooperative behavior and uses intricate communication to distribute tasks, share resources, and make decisions. New Tel Aviv University research now offers additional insight into the lethal interaction between cancer cells and the immune system's communications network.

Live and let-7: MicroRNA plays surprising role in cell survival
Researchers at the University of California, San Diego School of Medicine have identified a microRNA molecule as a surprisingly crucial player in managing cell survival and growth. The findings, published in the Oct. 7 issue of Cell Metabolism, underscore the emerging recognition that non-coding RNAs -- small molecules that are not translated into working proteins -- help regulate basic cellular processes and may be key to developing new drugs and therapies.

Researchers find link between tobacco use and viral infection that causes oral cancers
Johns Hopkins scientists have shown a strong association between tobacco use or exposure and infection with oral human papillomavirus type 16, the sexually transmitted virus responsible for mouth and throat cancers worldwide. The numbers of such cancers have increased 225 percent in the United States over the past two decades.

Drug regimen enough to control immune disease after some bone marrow transplants
Johns Hopkins and other cancer researchers report that a very short course of a chemotherapy drug, called cyclophosphamide, not only can prevent a life-threatening immune response in some bone marrow transplant recipients, but also can eliminate such patients' need for the usual six months of immune suppression medicines commonly prescribed to prevent severe forms of this immune response. Patients receive cyclophosphamide for two days after their bone marrow transplant, in addition to two other chemotherapy drugs given before the transplant.

New at-risk group identified for gastrointestinal stromal tumors
Researchers at the University of California, San Diego School of Medicine have, for the first time, clearly defined the epidemiology of gastrointestinal stromal tumors, which occur primarily in the lining of the stomach and small intestine. One key finding: patients of Asian descent, who have not previously been identified as an at-risk population, are 1.5 times more likely than other patient groups to be diagnosed with this type of tumor.

Survival molecule helps cancer cells hide from the immune system
A new study shows that the molecule nuclear factor kappa B helps tumors grow by inhibiting the body's ability to detect cancer cells. The molecule suppresses immune surveillance mechanisms, including the production of cells that inhibit immune responses. The research suggests that cancer immune therapy might be improved if combined with NF-kB inhibitors, and it provides new details about interactions between cancer cells and non-cancer cells that assist tumor growth.

Link between breast implants and cancer under investigation
An international research group including Viennese pathologist Lukas Kenner has reviewed cases of possible association between breast implants and a form of lymphoma that may develop tumors at a later stage. The researchers conclude that breast implants can cause a new subtype of the rare yet malignant lymphoma known as ALCL. The research results have been published in the journal Mutation Research.

The skin cancer selfie
Melanoma is the fifth most common cancer type in the US, and it's also the deadliest form of skin cancer. If caught early enough though, it is almost always curable. The gigapixel camera, developed by a team at Duke University, is essential 34 microcameras in one and has a high enough resolution to zoom in to a tiny freckle making routine screenings available to a larger number of people at a fraction of the cost.
