Stress granules ease the way for cancer metastasis

When cells are under duress, they curtail almost all protein synthesis and stash their mRNAs in stress granules. These structures help healthy cells, but they also allow tumor cells to survive harsh conditions. A protein named YB-1, which is overexpressed in many types of tumors, accumulates in stress granules, but researchers don’t know how YB-1 […]

Exercise linked to improved erectile, sexual function in men

While past studies have highlighted the relationship between better erectile function and exercise, African-American men have been underrepresented in this literature. “This study is the first to link the benefits of exercise in relation to improved erectile and sexual function in a racially diverse group of patients,” said Adriana Vidal, PhD, senior author of the […]

Experiments reveal key components of the body’s machinery for battling deadly tularemia

The team, led by Thirumala-Devi Kanneganti, Ph.D., a member of the St. Jude Department of Immunology, found key receptors responsible for sensing DNA in cells infected by the tularemia-causing bacterium, Francisella. Tularemia is a highly infectious disease that kills more than 30 percent of those infected, if left untreated. It can be readily transmitted by […]

Favorable 15-year survival outcomes for older prostate cancer patients with low-risk disease

Previous research by the study’s lead author Grace Lu-Yao, PhD, MPH, cancer epidemiologist at the Cancer Institute of New Jersey and professor of medicine at Rutgers Robert Wood Johnson Medical School, and colleagues examined 10-year outcomes for this population (JAMA, Vol. 302, No. 11). The 2009 research showed men diagnosed with prostate cancer beginning in […]

New insights into survival outcomes of Asian Americans diagnosed with cancer

“What we have found is that Asian Americans are an incredibly diverse group that cannot be indiscriminately combined together,” said Trinh, associate surgeon for the Division of Urology at BWH, faculty at the Center for Surgery and Public Health (CSPH) and lead author of the study. “With Asian Americans, there is important variation in socioeconomic […]

Precision medicine for adrenal cancer, study suggests

In a randomized phase 3 trial, adrenal cancer patients receiving the investigational drug linsitinib fared no better than patients receiving a placebo. But the researchers noticed a small subset of patients who had significant response and remained on the drug for an extended time. “While it was only a small subset of patients who responded to linsitinib, this remains very promising in the era of precision medicine,” says co-principle investigator Gary D. …

Early recall rates decline after second round of lung cancer screening

In the United States the National Lung Cancer Screening Trial (NLST) showed that annual lung cancer screening of high-risk individuals with LDCT reduces lung cancer mortality by 20% and overall mortality by 7%. There are now multiple lung cancer screening trials ongoing throughout the world, but one concern is the high number of early repeat scans for suspicious findings that are in fact not lung cancer. …
