UNC researchers create new research tool to help crack the histone code

University of North Carolina scientists have created a new research tool, based on the fruit fly, to help crack the histone code. This research tool can be used to better understand the function of histone proteins, which play critical roles in the regulation of gene expression in animals and plants.

Study shows low-dose oral iron supplementation after blood donation reduces hemoglobin recovery time

Among blood donors with normal hemoglobin levels, low-dose oral iron supplementation, compared with no supplementation, reduced the time to recovery of the postdonation decrease in hemoglobin concentration in donors with low or higher levels of a marker of overall iron storage (ferritin), according to a study in the February 10 issue of JAMA.

Scientists identify new cellular pathway affected in cystinosis

Scientists at The Scripps Research Institute have identified a new cellular pathway that is affected in cystinosis, a rare genetic disorder that can result in eye and kidney damage.

Andor Zyla sCMOS Camera enables instantaneous imaging of neuronal activity across whole organism for the first time

The speed, resolution and sensitivity of the Andor Zyla sCMOS camera has allowed the Vaziri research group in Vienna, Austria, to simultaneously image neuronal activity across an entire organism for the first time.

TAU researchers identify novel genetic mutation as source of specific rare disease

Rare diseases -- those that affect fewer than one in 200,000 people -- are often identified early in life. Some 30 percent of children afflicted by these "orphan diseases" do not live to see their fifth birthday. While the U.S. Orphan Drug Act of 1983 was written into law to promote research on the topic, the cost of identifying the source and progression of these diseases remains prohibitive for many families.

Experimental Ebola virus medication shows promise in monkeys

An experimental medication that targets a protein in Ebola virus called VP24 protected 75% of a group of monkeys that were studied from Ebola virus infection, according to new research conducted by the U.S. Army, in collaboration with Sarepta Therapeutics, Inc.

University of Tokyo researchers reveal how TLR9 binds to pathogen DNA

University of Tokyo researchers have elucidated how Toll-like receptor 9 (TLR9) binds to pathogen DNA, activating the innate immune system. This discovery is vital for the design of new antiviral, antibacterial, allergy and other drugs targeting TLR9.

New NIH grant to help restore function after spinal cord injury

Restoring function after spinal cord injury, which damages the connections that carry messages from the brain to the body and back, depends on forming new connections between the surviving nerve cells. While there are some delicate surgical techniques that reconnect the nerves, researchers are also looking at ways to restore the connections themselves at a cellular level.

Psychedelic drug prevents allergic asthma in mouse model

Research led by Charles Nichols, PhD, Associate Professor of Pharmacology and Experimental Therapeutics at the LSU Health New Orleans School of Medicine, has found that a psychedelic drug, (R)-DOI, prevents the development of allergic asthma in a mouse model.

New research provides hope for treating stroke using HUCBCs

Researchers have known that transplanted human umbilical cord cells (HUCBCs) can have a restorative effect on the brain and brain function following a stroke. However, just how the cells exert their therapeutic effects has not been clear. Now, a research team from the University of South Florida using animal models of stroke has found that the HUCBCs are most beneficial in preventing neuron loss when the Akt signaling pathway is activated by secretions from the HUCBCs and that Akt activation subsequently impacts a specific gene involved in reducing inflammation.

Japanese researchers explore use of bone marrow transplants to treat hypophosphatasia

Recent research carried out by a team of researchers in Japan has investigated the use of bone marrow transplants (BMTs) to treat hypophosphatasia (HPP). In this study, the researchers carried out BMT for two infants with HPP in combination with allogenic (other-donated) mesenchymal stem cell transplants (MSCTs). The allogenic MSC donors were a parent of the infant.

Scientists find that collagen 'cross-links' can determine tumor's ability to grow and spread

When skyscrapers go up, contractors rely on an infrastructure of steel beams and braces. Some cancers grow the same way, using a biological matrix from which the tumor can thrive and spread.

Drugs designed to target NHE9 protein could help fight glioblastoma

Applying lessons learned from autism to brain cancer, researchers at The Johns Hopkins University have discovered why elevated levels of the protein NHE9 add to the lethality of the most common and aggressive form of brain cancer, glioblastoma. Their discovery suggests that drugs designed to target NHE9 could help to successfully fight the deadly disease.

Discovery leads to new understanding of cancer metastasis

In a breakthrough in the understanding of how cancer spreads, researchers at the University of Virginia School of Medicine have identified a substance secreted by lung cancer cells that enables them to metastasize, beginning their deadly march to other sites in the body.

Mice genetically deficient in serotonin are more vulnerable to social stressors

Mice genetically deficient in serotonin -- a crucial brain chemical implicated in clinical depression -- are more vulnerable than their normal littermates to social stressors, according to a Duke study appearing this week in the Proceedings of the National Academy of Sciences.
