Prostate Cancer Treatment Might Help Some Glioblastoma Patients

Anti-androgens are known to increase the effectiveness of radiation therapy for prostate cancer patients, helping to slow the rate at which cancer can repair DNA damage caused by the treatment. Could the same strategy work against glioblastoma, an aggressive brain cancer that quickly grows resistant to radiation? Research led by […]

Should we sequence newborns’ DNA? The answer is complicated, study finds

Many adults seek genetic counseling or opt to send samples of their saliva to different companies, to find out if the specific patterns in their DNA may put them at higher risk for developing the disease. But many doctors and scientists — including National Institutes of Health Director Francis Collins […]

Immunotherapy-resistant cancers eliminated in mouse study

Immunotherapy has revolutionized cancer treatment by stimulating the patient’s own immune system to attack cancer cells, yielding remarkably quick and complete remission in some cases. But such drugs work for less than a quarter of patients because tumors are notoriously adept at evading an immune assault. A new study in […]

Brain’s Ability to Rewire Itself is Connected to Gene Expression

From birth, the normal human brain rewires itself in response to sensory stimulation from the outside world. To put it simply, it does this by strengthening the connections between certain brain cells through a junction called a synapse. The brain’s ability to change in this way is known as synaptic […]

Plant-based meat lowers some cardiovascular risk factors compared with red meat

A diet that includes an average of two servings of plant-based meat alternatives lowers some cardiovascular risk factors compared with a diet that instead includes the same amount of animal meat, Stanford Medicine scientists found. Swapping out red meat for plant-based meat alternatives can lower some cardiovascular risk factors, according […]

New Molecular Signaling Mechanism Determining Repair Pathways of DNA Double-Strand Breaks

A research team of Prof. Bae Jee-hyeon of College of Pharmacy and Prof. Lee Kang-seok, Kim Keun-pil and Kim Han-yong of Department of Life Science has identified a molecular signaling mechanism that determines the repair pathways of DNA double-strand breaks (DSB) causing serious damage to genomes. The research results were […]

Aging memories may not be ‘worse,’ just ‘different’

“Memory is the first thing to go.” Everyone has heard it, and decades of research studies seem to confirm it: While it may not always be the first sign of aging, some faculties, including memory, do get worse as people age. It may not be that straightforward. Zachariah Reagh, assistant […]

SFU chemist’s new process fast-tracks drug treatments for viral infections and cancer

Discovering antiviral and anticancer drugs will soon be faster and cheaper thanks to new research from SFU chemist Robert Britton and his international team. For the past 50 years, scientists have used manmade, synthetic, nucleoside analogues to create drug therapies for diseases that involve the cellular division and/or the viral […]

What Factors Help Predict Who Will Keep Their Memory into Their 90s?

Why do some people stay sharp into their 90s, even if they have the amyloid plaques in the brain that are associated with Alzheimer’s disease? And why do others reach their 90s without ever developing any plaques? These questions are explored in a new study published in the July 22, […]

Blood test could predict who will benefit from immunotherapy, researchers find

A test that detects changing levels of tumour fragments in the blood may be an easy, non-invasive and quick way to predict who will benefit from immunotherapy, University of Toronto researchers say. Immunotherapy can shrink tumours and prolong survival for patients for whom other treatments have failed. But it only helps […]
