Now Yale researchers have found a new inhibitor that in animal studies demonstrates greater potency against a wider variety of cancers, as well as against solid […]

Cardiovascular disease is often the result of blood vessels becoming clogged by plaques—buildups of fat, calcium, and other substances that may restrict blood flow. Not every plaque is created equal, however; some are more likely to induce a heart attack or stroke than others. Now a new three-dimensional imaging technique […]

According to a recent analysis of data from two major eye disease studies, adherence to the Mediterranean diet – high in vegetables, whole grains, fish, and olive oil – correlates with higher cognitive function. Dietary factors also seem to play a role in slowing cognitive decline. Researchers at the National […]

A study by Vanderbilt researchers has identified genomic alterations in early-stage adenocarcinomas of the lung that may indicate whether the lesions develop into aggressive tumors.

In the largest study to date of proteins related to Alzheimer’s disease, a team of researchers has identified disease-specific proteins and biological processes that could be developed into both new treatment targets and fluid biomarkers. The findings suggest that sets of proteins that regulate glucose metabolism, together with proteins related to […]

Immunotherapies have revolutionized treatment for people with a variety of cancers. But when given to those with triple-negative breast cancer (TNBC), a particularly aggressive form of the disease, less than 20% respond. “A big question in the field has been, Why are the rest not responding?” says Rumela Chakrabarti, an assistant […]

A new study identifies some of the most critical genes that may drive a rare but deadly liver cancer, providing a road map for developing drugs that target those genes. The cancer, fibrolamellar carcinoma, accounts for 1-5% of all liver cancers, and disproportionately affects children and young adults. By the […]

A pioneering study has shed new light on how a group of novel organelle-based disorders affect cells. The study led by Professor Michael Schrader from the University of Exeter, and featuring an international, multi-disciplinary team of scientists, has explored on peroxisome alterations and their contribution to the disease. Organelles are the functional units […]

A multidisciplinary team of researchers at the University of Illinois at Urbana-Champaign has developed tiny sensors that measure oxygen transport in bovine lung tissue. The study – which establishes a new framework for observing the elusive connection between lung membranes, oxygen flow and related disease – was published in the […]

Researchers trying to turn off a gene that allows cancers to spread have made a surprising U-turn. By making the gene overactive and functional in the hearts of mice, they have triggered heart cell regeneration. Since adult hearts cannot usually repair themselves once damaged, harnessing the power of this gene […]

Timing is everything. A fresh example supporting the old saying has been found in connection with the systems regulated by biological clocks. Research on circadian rhythms, our internal 24-hour patterns that affect sleep-wake and metabolic cycles, has shown that timing is key for human health. When our activities and internal […]

A new technique makes it possible to track changes in gene activity across a cell’s entire genome over time in more detail than has been possible before, researchers in Seattle report. “We hope this method will improve our understanding of normal cell physiology and as well as of cell dynamics […]

Lung cancer spreads to the brain in about one-quarter of patients with an advanced form of the disease. To date, radiation has been the only treatment option, but it comes with toxic side effects. Researchers at Yale Cancer Center (YCC) have found that the use of the checkpoint inhibitor pembrolizumab in […]

Autoimmunity, a condition in which the body’s immune system reacts with components of its own cells, appears to be increasing in the United States, according to scientists at the National Institutes of Health and their collaborators. In a study published in Arthritis and Rheumatology, the researchers found that the prevalence […]

For patients with malignant brain tumors, the prognosis remains dismal. With the most aggressive treatments available, patients are usually only expected to live about 14 months after diagnosis. This is because, chemotherapy, the most common form of treatment for cancer, is uniquely challenging for brain tumor patients. The delicate organ […]

This open access paper is an example of one of the less well known connections between processes of aging. Loss of efficiency of the cellular maintenance processes of autophagy is a characteristic of cells in old tissues. Here, researchers note that this dysfunction in the hematopoietic cells responsible for creating blood and immune […]

In most cell therapies, the transplanted cells do not survive for long, or in large numbers. They produce beneficial effects, such as reduced inflammation or enhanced regeneration, via signaling that changes the behavior of native cell populations. Considerable effort is going into finding ways to make cells used in therapy survive for […]

A prospective “PARP inhibitor” drug that has struggled to show effectiveness in clinical trials against cancers can be structurally modified to greatly increase its power to kill tumor cells, researchers from Penn Medicine report in Science. The team also showed that PARP inhibitor compounds can be “tuned” in the opposite […]
