Dopamine Surge Reveals How Even for Mice, ‘There’s No Place Like Home’

“There’s no place like home,” has its roots deep in the brain. Using fiber photometry, scientists are the first to show that home evokes a surge of dopamine in mice that mimics the response to a dose of cocaine. The study demonstrates how dopamine rises rapidly in mice moved from a simple recording chamber to their home cage, but less so when they return to a cage not quite like the one they knew.

Ovarian Cancer Screening Study Focuses on Early Detection in Women at Low Risk

Atlantic Health System is enrolling women in a landmark study that uses a simple blood test for the CA-125 protein to screen women who are at low risk for ovarian cancer. The purpose of the clinical trial is to help determine whether this test can catch ovarian cancer early in women who would not normally be screened for it. Atlantic Health System hospitals are the only centers in the New York metro region to participate in the study, and have the third highest enrollment numbers in the nation.

Study Shows Promise for Non-Small Cell Lung Cancer Patients Who Require New Treatment Options

A new type of immunotherapy treatment for metastatic non-small cell lung cancer (NSCLC) is being tested by Missak Haigentz, Jr., MD, medical director of hematology and oncology for Atlantic Health System. Early results appear promising in this phase 1/2 clinical trial of ADXS-503 being developed by Advaxis, Inc., a new type of cancer therapy which targets “hotspot” mutations that commonly occur in specific cancer types, both by itself and in combination with immunotherapy Keytruda® (pembrolizumab), which is commonly used to treat this type of lung cancer. Dr. Haigentz and colleagues published early results of this study in conjunction with ASCO 2020, the world’s premier scientific meeting for clinical research in oncology.

Diagnostic Biomarkers Uncovered for Rare Kidney Cancer

Using next-generation RNA sequencing techniques, a team of scientists from the University of Michigan Rogel Cancer Center has uncovered the gene signature of chromophobe renal cell carcinoma (ChRCC) and have extensively tested the expression of three new biomarkers. The subtype is the third most common type of renal cell carcinoma, comprising about 5% of cases.

Better Biosensor Technology Created for Stem Cells

A Rutgers-led team has created better biosensor technology that may help lead to safe stem cell therapies for treating Alzheimer’s and Parkinson’s diseases and other neurological disorders. The technology, which features a unique graphene and gold-based platform and high-tech imaging, monitors the fate of stem cells by detecting genetic material (RNA) involved in turning such cells into brain cells (neurons), according to a study in the journal Nano Letters.

Painless Tape Strips Used to Detect Molecular Changes in Skin of Children with Eczema

In a study using non-invasive tape strips in young children with eczema (or atopic dermatitis), researchers found many molecular signs of immune dysfunction and skin changes that relate to disease activity. These signs (or biomarkers) were present even before eczema was visible and can be used to track disease activity over time. With more research, these biomarkers also may help predict response to medicine and development of conditions associated with eczema, such as asthma, other allergies, infections and even attention deficit hyperactivity disorder (ADHD). Findings were published in JAMA Dermatology.
