Common drug to treat cancer reverses Alzheimer’s symptoms in mice

A drug commonly used to treat cancer can restore memory and cognitive function in mice that display symptoms of Alzheimer's disease, new UBC research has found.

Circulating tumor cells found to form clusters that cause breast cancer metastases

A new study reports that circulating tumor cells that exhibit the features of stem cells employ ICAM1 to enable the formation of CTC clusters.

Scientists find two proteins that pair up to build lifelines to cancer cells

In human cancer cell and mouse studies, researchers from Johns Hopkins Medicine have found that a set of proteins work in tandem to build supply lines that deliver oxygen and nutrients to tumors, enabling them to survive and grow.

Study uncovers key factors immune cells need to survive in the battle against cancer

A study headed by scientists at Massachusetts General Hospital unravels certain crucial factors required for the survival of immune cells in the fight against cancer.

Pushing organ-on-a-chip microdevices to new levels to improve ovarian cancer treatment

In the evolving field of cancer biology and treatment, innovations in organ-on-a-chip microdevices allow researchers to discover more about the disease outside the human body.

Stiffness of protein fibers plays a key role in controlling cell movement, study shows

A new study, led by University of Minnesota Twin Cities engineering researchers, shows that the stiffness of protein fibers in tissues, like collagen, are a key component in controlling the movement of cells.

Scientists provide insights on immune evasion of metastatic cancer cells in lymph nodes

Lymph nodes are critical to the body's immune response against tumors but paradoxically, cancer cells that spread, or metastasize, to lymph nodes can often avoid being eliminated by immune cells.

Study reveals the basis of oxygenation fluctuations in brain

The brain is supplied with sufficient nutrients and oxygen due to the blood flow; however, the oxygenation is likely to fluctuate distinctly and uniformly.

Experimental model reveals the protective role of antioxidants in neurodegenerative disorders

Researchers used a model to replicate the blood-brain barrier and successfully demonstrated how antibody guards the brain against inflammation.

Kirigami-inspired stent could deliver drugs to tubular organs

Inspired by kirigami, the Japanese art of folding and cutting paper to create three-dimensional structures, MIT engineers and their collaborators have designed a new type of stent that could be used to deliver drugs to the gastrointestinal tract, respiratory tract, or other tubular organs in the body.

Novel platform may lead to more improved gene therapies

Researchers from RCSI University of Medicine and Health Sciences have developed polypeptide-based materials that serve as effective vectors in delivering gene therapies.

Daily intake of fruits can lower risk of type 2 diabetes

Eating at least two serves of fruit daily has been linked with 36 percent lower odds of developing type 2 diabetes, a new Edith Cowan University (ECU) study has found.

Study shows why “the brain's memory center” is vulnerable to damage, degeneration

In a world first, scientists from the University of Sussex have recorded blood oxygen levels in the hippocampus and provided experimental proof for why the area, commonly referred to as 'the brain's memory center', is vulnerable to damage and degeneration, a precursor to Alzheimer's disease.

“Paralyzed” immune cells can be reactivated by drugs in IDH-mutant gliomas

Brain tumor cells with a certain common mutation reprogram invading immune cells. This leads to the paralysis of the body's immune defense against the tumor in the brain. Researchers from Heidelberg, Mannheim, and Freiburg discovered this mechanism and at the same time identified a way of reactivating the paralyzed immune system to fight the tumor.

New method can enable early detection and treatment of cerebral aneurysms

Cerebral aneurysms are malformations caused by abnormalities on the walls of blood vessels in the brain. When these blood vessels rupture, about 30% of the sufferers die on the spot, giving these the rightful label of 'ticking bombs in the head'.

Highly efficient method to identify the genetic “switches” that control gene expression

Scientists have created a high-throughput method to help explain and regulate gene expression for the treatment of diseases like beta-thalassemia and sickle cell disease.

Macrophages perform necessary damage-control function following tissue injury

Cardiovascular disease, the most common cause of death, is the result of oxygen deprivation as blood perfusion to affected tissue is prevented. To halt the development of the disease and to promote healing, re-establishment of blood flow is crucial.

Natural molecule can effectively block the binding of human antibodies to SARS-CoV-2

Researchers have found that a natural molecule can effectively block the binding of a subset of human antibodies to SARS-CoV-2. The discovery may help explain why some COVID-19 patients can become severely ill despite having high levels of antibodies against the virus.

POSTECH researchers bioengineer a novel drug-delivering adhesive patch platform

Blood vessels deliver nutrients and oxygen to each organ in our body. They are difficult to completely restore to their original conditions once damaged by myocardial infarction or severe ischemic diseases. This is because various angiogenic growth factors must be applied sequentially in order to restore the vascular structure.
