Prostate cancer now detectable by imaging-guided biopsy

Ground-breaking research by a UCLA team of physicians and engineers demonstrates that prostate cancer can be diagnosed using image-guided targeted biopsy.

Traditionally found only by blind biopsy, a procedure that dates from the 1980s, prostate cancer now appears detectable by direct sampling of tumor spots found using Magnetic Resonance Imaging (MRI) in combination with real-time ultrasound, according to the UCLA study released Dec. 10, 2012 early online for the January 2013 issue of The Journal of Urology®.

Targeted prostate biopsy has potential to improve diagnosis of prostate cancer

New York, NY, December 10, 2012 – Diagnosis of prostate cancer remains imperfect. Current methods of prostate biopsy are limited by over detection of slow-growing tumors and under detection of clinically relevant cancers. Investigators at the University of California-Los Angeles Department of Urology have found that a new technique of targeted biopsy in a clinic setting, using local anesthesia, may improve diagnosis and aid in selecting which patients are suitable for active surveillance and which need focal therapy (noninvasive techniques for destroying small tumors within the prostate).

'Commitment-phobic' adults could have mom and dad to blame

Afraid to commit to a relationship? According to new research from Tel Aviv University, it could be just one more thing to blame on your parents.

A study of the romantic history of 58 adults aged 22-28 found that those who avoid committed romantic relationships are likely a product of unresponsive or over-intrusive parenting, says Dr. Sharon Dekel, a psychologist and researcher at the Bob Shappell School of Social Work.

UCLA cancer scientists identify liposarcoma tumors that respond to chemotherapy

Liposarcoma, the most common type of sarcoma, is an often lethal form of cancer that develops in fat cells. It is particularly deadly, in part, because the tumors are not consistently visible with positron emission tomography (PET) scans that use a common probe called FDG and because they frequently do not respond to chemotherapy.

Study identifies potential new pathway for drug development

A newly found understanding of receptor signaling may have revealed a better way to design drugs. A study from Nationwide Children's Hospital suggests that a newly identified group of proteins, alpha arrestins, may play a role in cell signaling that is crucial to new drug development. The study appears in PLOS ONE.

Researchers identify therapeutic targets in neurofibromatosis

Neurofibromatosis-1 (NF1) is an inherited disorder caused by mutations in the NF1 gene that result in the formation of nervous tissue tumors (neurofibromas) in the skin, subcutaneous tissue, and the cranial and spinal root nerves. Additionally, NF1 patients are predisposed to juvenile myelomonocytic leukemia (JMML), myeloproliferative disorders, and malignant peripheral nerve sheath tumors (MPNST). NF1 encodes a protein that serves as a negative regulator of a signaling pathway composed of RAS, RAF, MEK, and ERK proteins, known as MAPK signaling cascades.

Brown fat transplants help mice lose weight

Brown fat is a specialized tissue in mammals that is used to generate heat (thermogenesis). While white fat is associated with increased body mass, brown fat is associated with a lower body mass index (BMI) and consumes large amounts of energy. Researchers have long been intrigued by the idea of brown fat transplant as a therapeutic tool to combat obesity. In this issue of the Journal of Clinical Investigation, researchers led by Laurie Goodyear at the Joslin Diabetes Center in Boston, performed brown fat transplants in mice to determine if this intervention could treat obesity.

Study identifies targeted molecular therapy for untreatable NF1 tumors

CINCINNATI – Researchers conducting a preclinical study in mice successfully used targeted molecular therapy to block mostly untreatable nerve tumors that develop in people with the genetic disorder Neurofibromatosis 1 (NF1).

Scientists from Cincinnati Children's Hospital Medical Center report their findings online Dec. 10 in the Journal of Clinical Investigation.

From fish to man: Research reveals how fins became legs

Vertebrates' transition to living on land, instead of only in water, represented a major event in the history of life. Now, researchers reporting in the December issue of the Cell Press journal Developmental Cell provide new evidence that the development of hands and feet occurred through the gain of new DNA elements that activate particular genes.

(Antibody) orientation matters

The orientation of antibody binding to bacteria can mean life or death to the bug, according to a study published in The Journal of Experimental Medicine on December 10th. These findings may help explain why these bacteria cause millions of localized infections, but more serious, systemic blood infections are rare.

To fight incurable metastatic breast cancer, resistance must be broken

One of the most frustrating truths about cancer is that even when a treatment works, it often doesn’t work for long because cancer cells find ways to resist. However, researchers reporting studies done in mice in the December 11, 2012, issue of Cancer Cell, a Cell Press publication, may have a way to stay one step ahead in the case of aggressive metastatic breast cancer.

The findings emphasize the importance of basic cancer biology for advancing treatments that are more effective and less toxic, the researchers say.

Joslin scientists: Brown adipose tissue beneficial for metabolism and glucose tolerance

BOSTON – December 10, 2012 – Joslin Diabetes Center scientists have demonstrated that brown adipose tissue (BAT) has beneficial effects on glucose tolerance, body weight and metabolism. The findings, which may lead to new treatments for diabetes, appear in the upcoming issue of the Journal of Clinical Investigation.

Internet use can reduce fatalistic view of cancer

Washington, DC (December 10, 2012) – Many Americans have fatalistic views on cancer prevention—they believe that getting cancer is a matter of luck or fate. Recent research, published in the Journal of Communication, found that people who use the internet to inquire about their health are more likely to have a positive outlook on cancer prevention and diagnosis.

Alcohol pricing policies save lives and increase profits, experts say

For immediate release – Dec. 10, 2012 (Toronto) – Setting minimum prices for alcohol increases health and economic benefits, say international experts, who met today for a seminar on alcohol pricing and public health.

The meeting — sponsored by the Centre for Addiction and Mental Health (CAMH), the Centre for Addictions Research of British Columbia (CARBC) and the Canadian Centre on Substance Abuse (CCSA) — focused on new analyses on Ontario and other provinces where minimum pricing policies have been implemented for a number of years.
