Tumor-targeting system uses cancer's own mechanisms to betray its location
- Details
- Category: Research
By hijacking a cancer cell's own metabolism, researchers have found a way to tag and target elusive cancers with small-molecule sugars. This opens treatment pathways for cancers that are not responsive to conventional targeted antibodies, such as triple-negative breast cancer.
How eating less can slow the aging process
- Details
- Category: Research
There's a multi-billion-dollar industry devoted to products that fight signs of aging, but moisturizers only go skin deep. Aging occurs deeper - at a cellular level - and scientists have found that eating less can slow this cellular process. Recent research published in Molecular & Cellular Proteomics offers one glimpse into how cutting calories impacts aging inside a cell. The researchers found that when ribosomes - the cell's protein makers - slow down, the aging process slows too.
Inducing an identity crisis in liver cells may help diabetics
- Details
- Category: Research
It is now possible to reprogram cells from the liver into the precursor cells that give rise to the pancreas by altering the activity of a single gene. A team of researchers at the Max Delbrück Center for Molecular Medicine in the Helmholtz Association (MDC) has now accomplished this feat in mice. Their results should make it feasible to help diabetic patients through cell therapy.
An alternative theory on how aspirin may thwart cancer
- Details
- Category: Research
Studies abound that point to a role for plain old aspirin in keeping deadly cancers at bay. While aspirin is not yet part of mainstream treatment for any cancer, it is recommended by the U.S. Preventive Services Task Force for certain adults to help prevent colorectal cancer. But researchers have puzzled over how exactly the "wonder drug" works to ward off cancer. Most think it has to do with the drug's inflammation-lowering effects.
Sex, drugs, and rock and roll chemistry in the brain
- Details
- Category: Research
The same brain-chemical system that mediates feelings of pleasure from sex, recreational drugs, and food is also critical to experiencing musical pleasure, according to a study by McGill University researchers published today in the Nature journal Scientific Reports.
Encouraging clinical results for an antibody drug to prevent or treat HIV
- Details
- Category: Research
A new biologic agent - the most potent of its kind so far - is showing early promise as part of a potential new strategy for treating HIV. The drug, known as 10-1074, may also offer a new way to prevent viral infection in people who are at high risk to acquire HIV, the virus that causes AIDS.
Nuts can inhibit the growth of cancer cells
- Details
- Category: Research
Roasted and salted, ground as a baking ingredient or fresh from the shell - for all those who enjoy eating nuts, there is good news from nutritionists at Friedrich Schiller University Jena (Germany). Their latest research shows that nuts can inhibit the growth of cancer cells.
