Cancerous tumors need nutrients to grow, so they secrete factors promoting new blood-vessel formation to feed themselves. Researchers have long known that cells in low-oxygen environments at the center of the tumor send out these factors, but a new study by University of Illinois researchers found that stemlike cells at […]

Researchers at University of California San Diego School of Medicine report that a single infusion of wildtype hematopoietic stem and progenitor cells (HSPCs) into a mouse model of Friedreich’s ataxia (FA) measurably halted cellular damage caused by the degenerative disease. The findings, published in the journal Science Translational Medicine, suggest a […]

As cells with a propensity for cancer break down food for energy, they reach a fork in the road: They can either continue energy production as healthy cells, or shift to the energy production profile of cancer cells. In a new study published Monday (Oct. 23, 2017) in the journal Nature […]

A new therapy that uses blood-vessel-lining cells to regenerate damaged tissue has the potential to treat liver cirrhosis, Weill Cornell Medicine scientists demonstrate in new research. The small-scale animal study, published in the journal Radiology, was a test of the basic feasibility of the cell delivery technique and not designed to […]

A sharp rise in the number of women seeking BRCA genetic testing to evaluate their risk of developing breast cancer was driven by multiple factors, including celebrity endorsement, according to researchers at the University of Georgia. “BRCA testing and counseling provide important information on the risk of developing breast and […]

Seventy-two new genetic variants that contribute to the risk of developing breast cancer have been identified by a major international collaboration involving hundreds of researchers worldwide. Of these variants, reported today in the journals Nature and Nature Genetics, 65 are common variants that predispose to breast cancer and a further seven predispose specifically […]

A human gene called p53, which is commonly known as the “guardian of the genome,” is widely known to combat the formation and progression of tumors. Yet, mutant forms of p53 have been linked to more cases of human cancer than any other gene. Investigating core mechanisms of how cancer cells […]

A framed, black-and-white photo of Dr. Janko Nikolich-Zugich rests on a bookshelf in his office. He is seen in profile, head bent, a pen tucked into the pocket of his lab coat. Nikolich-Zugich is at work at his lab bench at New York's Memorial Sloan Kettering Cancer Center. Twenty-five years after […]

Breast cancer cells recycle ammonia, a waste byproduct of cell metabolism, and use it as a source of nitrogen to fuel tumor growth, report scientists from Harvard Medical School in the journal Science. The findings, published online ahead of print on Oct. 12, show that the presence of ammonia accelerates proliferation […]

Following a successful clinical trial involving Dana-Farber Cancer Institute and Brigham and Women's Hospital, the first chimeric antigen receptor (CAR) T-cell therapy for adult cancers was approved by the Food and Drug Administration (FDA) today. Dana-Farber/Brigham and Women's Cancer Center, the only facility in the northeast to be part of the clinical […]

Siteman Cancer Center at Barnes-Jewish Hospital and Washington University School of Medicine in St. Louis is one of the first centers nationwide to offer a new immunotherapy that targets certain blood cancers. Newly approved by the Food and Drug Administration (FDA) for types of advanced non-Hodgkin lymphoma in adults, the CAR-T […]

A new study published in Nature Communicationsreveals that it is possible to repurpose the function of different mature cells across the body — and harvest new tissue and organs from these cells. The research tracks the transformation of genetically manipulated cells into melanocytes, which are responsible for the production of skin […]

Scars may fade, but the skin remembers. New research from The Rockefeller University reveals that wounds or other harmful, inflammation-provoking experiences impart long-lasting memories to stem cells residing in the skin, teaching them to heal subsequent injuries faster. These stem cells, which replenish the skin’s outer layer take their cue […]

Some people may have mild memory problems without an increased risk of Alzheimer‘s. However, it is one of the factors that may reveal that a possibility to develop this disease is high. A new study lead by the University of Birmingham has shown that delayed response to written word could […]

A new study published in Nature, conducted by an alliance between industry and academia involving the University of Liverpool, highlights a new approach to targeting key cancer-linked proteins, thought to be ‘undruggable’. The majority of cancers have a faulty or inactive gene, p53, which allows them grow out of control. The […]

A drug isolated from a marine pest holds promise for treating some of the world’s nastiest diseases, and researchers would love to find out just how effective it is – if only they could get their hands on more. As it stands, the world’s supply of the chemical is down […]

Researchers at MIT have developed a synthetic gene circuit that triggers the body’s immune system to attack cancers when it detects signs of the disease. The circuit, which will only activate a therapeutic response when it detects two specific cancer markers, is described in a paper published in the journal Cell. […]

People who have a healthier diet throughout their adult lives are more likely to be stronger and fitter in older age than those who don’t, according to a new study led by the University of Southampton. Scientists from the University’s Medical Research Council Lifecourse Epidemiology Unit (MRC LEU), in partnership with colleagues […]

A rare cancer in patients with breast implants may be on the rise, but not all patients and physicians may be aware of the risks associated with the procedure, according to a group of Penn State College of Medicine researchers. Breast implant-associated anaplastic large cell lymphoma — or BIA-ALCL — […]

Menopause causes metabolic changes in the brain that may increase the risk of Alzheimer’s disease, a team from Weill Cornell Medicine and the University of Arizona Health Sciences has shown in new research. The findings, published in PLoS One, could help solve a long-standing mystery about Alzheimer’s: namely, why women get […]

A Food and Drug Administration warning against a tool used to break up fibroid tissue during laparoscopic surgeries has led to a shift toward more invasive surgeries for hysterectomies for women with uterine fibroids, according to a new study by researchers at UCSF Health. The authors say this shift could […]

Many people with Parkinson‘s disease eventually develop dementia as disease progresses. While it is incurable, doctors do have tool to help manage the condition and improve the quality of life, if dementia signs are noticed early. Now scientists from UCL have developed a new 'Cats-and-Dogs' test to predict dementia among […]

A discovery in Marina Guenza's UO chemistry lab, published in a major physics journal, is already being tapped by outside scientists working on a new medical treatment for tuberculosis.
