Approach avoids potential toxicity Pacific Northwest National Laboratory and Washington State University researchers have developed a novel way to deliver drugs and therapies into cells at the nanoscale without causing toxic effects that have stymied other such efforts. The work could someday lead to more effective therapies and diagnostics for […]

Our DNA is under constant attack. The delicate molecule that contains our genetic information is extremely vulnerable to everything from environmental agents, such as radiation, to the chemicals in the air we breathe and the food we eat. Genome instability can lead to genetic disorders, chronic diseases and a predisposition […]

A handful of brain cells deep in the brain may play a surprising role in controlling women’s bone density, according to new research by UC San Francisco and UCLA scientists. In a study published in Nature Communications, researchers showed that blocking a particular set of signals from these cells causes female […]

During normal pregnancy, mothers always gain body weight within a proper range. However, many women worry that extra pounds put on during pregnancy will not be lost after childbirth and, in fact, past studies have shown that excessive gestational weight gain is associated with immediate postpartum weight retention. But in […]

Studying fruit flies, an international team led by Harvard Medical School researchers reports that it has uncovered one of the molecular roots of cachexia, a poorly understood and currently incurable muscle-wasting and fat-loss condition responsible for as many as one-third of cancer deaths. The findings, published online in Developmental Cell, suggest […]

The study was co-authored by Dr David Ellis from Lancaster University with Dr Ross McQueenie from the University of Glasgow, along with colleagues from the University of Aberdeen. In the largest […]

With the help of sponges inserted in the bloodstream to absorb excess drugs, doctors are hoping to prevent the dangerous side effects of toxic chemotherapy agents or even deliver higher doses to knock back tumors, like liver cancer, that don’t respond to more benign treatments. The “drug sponge” is an […]

It is often expected that as parents age, the children they once cared for will need to care for them. Expectations become less clear in non-traditional families and can be even murkier when the aging adult might be responsible for his or her situation. In a new study about responsibility […]

Scientists at UW Medicine’s Institute for Protein Design  have created a new protein that mimics the action of a key immune regulatory protein, interleukin 2 (IL-2).  IL-2 is a potent anticancer drug and an effective treatment for autoimmune disease, but its toxic side effects have limited its clinical usefulness. In a paper in […]

How does your garden grow? A paper published in the journal Nature gives scientists a deeper understanding of that very thing – the molecular mechanisms that cause plant tissues and organs to get larger and more complex after seeds germinate. Ross Sozzani, an NC State University plant biologist, is part of an […]

Our bodies hold roughly 14 trillion cells, each containing a nucleus with DNA measuring two meters long by 20 atoms wide. To fit inside each nucleus, DNA coils around specialized proteins. These spools of wrapped DNA inhibit gene regulatory proteins from binding to protein-coding stretches along the genome, which help […]

Pairing a novel personalized cancer vaccine with an established immunotherapy drug administered to patients in a new way, Harvard Medical School scientists at Dana-Farber Cancer Institute are testing a first-of-its-kind strategy aimed at improving outcomes for kidney cancer patients who are at high risk of recurrence following surgery. This two-pronged approach to […]

Lifestyle changes often follow a cancer diagnosis, both during treatment and after. Eating well is often the first step. And there is good reason for it. A healthy diet can help prolong life for cancer patients and cancer survivors, says University of Michigan Rogel Cancer Center member Suzanna Zick, N.D., MPH. Surveys show […]

Many breast cancer drugs block estrogen receptors inside cancer cells. Blocking the receptors early in disease progression staves off metastasis. But most patients with advanced disease eventually develop drug resistance, leaving doctors desperate for alternatives. Researchers from Case Western Reserve University School of Medicine, Argonne National Laboratory and the Lawrence […]

Cancer is a complex set of diseases that researchers are studying to improve therapy and develop prevention strategies. Although there is no single way to prevent cancer, oncologists agree that taking steps to mitigate risk is key. Experts at The Ohio State University Comprehensive Cancer Center – Arthur G. James […]

New research from The Ohio State University Comprehensive Cancer Center – Arthur G. James Cancer Hospital and Richard J. Solove Research Institute (OSUCCC – James) underscores the importance of genomic analysis of rare malignant tumors that are genetically unstable and have high numbers of gene mutations.
