Researchers unravel mystery of NPM1 protein in acute myeloid leukemia

While it has long been recognized that mutated gene NPM1 plays an important role in acute myeloid leukemia, no one has determined how the normal and the mutated forms of the protein NPM1 function.

Study uncovers link between gut disruption and aging

A new study has shed light on how the disruption of commensal bacteria within the gut can affect the immune system and lead to age-related pathologies.

First bifacial molecule can invade double-stranded DNA or RNA

Carnegie Mellon University researchers have developed a synthetic molecule that can recognize and bind to double-stranded DNA or RNA under normal physiological conditions. The molecule could provide a new platform for developing methods for the diagnosis and treatment of genetic conditions.

New study provides deeper insight into chromosome segregation during mitosis

When a cell divides—a process known as mitosis—its chromosomes need to be separated and evenly distributed into the newly created daughter cells. Although this is known to be extremely complicated and to feature a range of cellular components, many of its details remain unclear, which has hampered efforts to develop treatments for when mitosis goes awry.

Gladstone scientists gain new insights into the aging brain

The protein klotho has been shown to promote longevity and counteract aging-related impairments. Having more klotho seems to allow for longer and healthier lives, whereas a depletion of this molecule accelerates aging and may contribute to age-related diseases.

Researchers discover how mitochondria deploy a powerful punch against disease-causing bacteria

The constant battle for dominance between disease-causing bacteria and our immune systems has led to the evolution of some crafty warfare tactics on both sides.

Study shows novel strategy to reduce breast cancer bone metastasis

Uncovering a novel mechanism that promotes growth of breast cancer bone metastasis has revealed a potential Achilles' heel for these cancer cells. Reported in the journal Cancer Cell, the study shows that interfering with this mechanism can reduce the risk of relapses in animal models.

Study shows how pneumococci challenge the immune system

Pneumococci are the most common cause of respiratory tract infections, such as otitis and sinusitis, as well as of severe infections like pneumonia and meningitis.

Kawasaki disease may be triggered by a combination of environmental factors

A new study has found that Kawasaki disease (KD) is not caused by one single factor but has multiple environmental triggers.

UCI researchers accelerate and simplify directed evolution bioengineering technique

In a process known as directed evolution, scientists reengineer biomolecules to find ones that perform beneficial new functions. The field is revolutionizing drug development, chemical engineering and other applications, but to realize its promise involves painstaking and time-consuming laboratory work.

Scientists uncover hidden estrogen receptors in epithelial breast cells

Estrogens are hormones that play central roles in the development and the physiology of the breast, but also are involved in breast cancer. Like all hormones, estrogens exert their biological effects by binding to dedicated receptors in the target cell.

Cells retain memory of chemical signals to which they are exposed

We all start out as a clump of identical cells. As these cells divide and multiply, they gradually take on distinct identities, acquiring the traits necessary to form, for instance, muscle tissue, bone, or nerves. A recent study from Rockefeller scientists offers new insight into how these cellular identities are cultivated over the course of development.

Bfr organizes symposia for research on viruses and antimicrobial resistance in food chain

Against this background, the German Federal Institute for Risk Assessment is organising two symposia dealing with microbial risks in food in November 2018: "Food-associated viruses" on 7 November and "Antimicrobial resistance in the food chain" on 8/9 November.

Researchers develop powerful method to solve structures of small molecules

Small molecules -- from naturally occurring metabolites and hormones to synthetic medicines and pesticides -- can have big effects on living things. But for scientists to understand how the molecules work and how to design beneficial ones, they need to know the precise arrangement of atoms and chemical bonds.
