Proximity to nearby muscle cells may make prostate cancer cells more likely to invade nearby tissues and spread to other organs, according to an early study by researchers at the National Institutes of Health.

In a study of fruit flies, NIH scientists suggested that the body’s immune system may play a critical role in the damage caused by aging brain disorders. The results are based on experiments in which the researchers altered the activity of Cdk5, a gene that preclinical studies have suggested is important for early brain development and may be involved in neurodegenerative diseases, such as ALS, Alzheimer’s and Parkinson’s disease.

An interdisciplinary team of three Virginia Tech faculty members affiliated with the Macromolecules Innovation Institute has created a drug delivery system that could radically expand cancer treatment options.
It’s one thing to detect sites in the genome associated with mental disorders; it’s quite another to discover the biological mechanisms by which these changes in DNA work in the human brain to boost risk. In their first concerted effort to tackle the latter, 15 collaborating research teams of the National Institutes of Health-funded PsychENCODE Consortium(link is external) leveraged statistical power gained from a large sample of about 2000 postmortem human brains.

Researchers at MIT, Draper, and Brigham and Women’s Hospital have designed an ingestible capsule that can be controlled using Bluetooth wireless technology. The capsule, which can be customized to deliver drugs, sense environmental conditions, or both, can reside in the stomach for at least a month, transmitting information and responding to instructions from a user’s smartphone.
In general, women who have had children have a lower risk of breast cancer compared to women who have never given birth. However, new research has found that moms don’t experience this breast cancer protection until many years later and may face elevated risk for more than 20 years after their last pregnancy.
Researchers at Stanford University, Palo Alto, California, have created a noninvasive technology that detects when nerve cells fire based on changes in shape. The method could be used to observe nerve activity in light-accessible parts of the body, such as the eye, which would allow physicians to quantitatively monitor visual function at the cellular level. The study was published in the journal Light: Science and Applications. The work was funded by the National Eye Institute, part of the National Institutes of Health.

Researchers have discovered that a hormone, fibroblast growth factor 21 (FGF21), is extremely elevated in mice with liver disease that mimics the same condition in patients with methylmalonic academia (MMA), a serious genomic disorder. Based on this finding, medical teams treating patients with MMA will be able to measure FGF21 levels to predict how severely patients’ livers are affected and when to refer patients for liver transplants. The findings also might shed light on more common disorders such as fatty liver disease, obesity and diabetes by uncovering similarities in how MMA and these disorders affect energy metabolism and, more specifically, the function of mitochondria, the cells’ energy powerhouses. The study, conducted by researchers at the National Human Genome Research Institute (NHGRI), part of the National Institutes of Health, was published Dec. 6 in JCI Insight.
Infants and toddlers in low-income, rural areas may be at higher risk for second- and third-hand smoke than previously reported, according to a study supported by the National Institutes of Health. Approximately 15 percent of children in the study tested positive for cotinine, a byproduct formed when the body breaks down nicotine, at levels comparable to those of adult smokers. About 63 percent of children in the study had detectable levels of cotinine, suggesting widespread exposure to smoke. The study appears in Nicotine & Tobacco Research.

An interim analysis of a large phase 3 clinical trial found that the combination of ibrutinib plus rituximab was superior to standard treatment for patients age 70 and younger with previously untreated chronic lymphocytic leukemia (CLL). The trial met its primary endpoint of an improvement in progression-free survival (the length of time patients live before their disease worsens). The combination also improved overall survival, the trial’s secondary endpoint. In general, patients in the ibrutinib–rituximab arm were less likely to experience serious side effects than those in the standard treatment arm. Until now, the standard treatment for previously untreated CLL has been a six-month course of FCR, which combines the chemotherapy drugs fludarabine and cyclophosphamide with rituximab.
