Specific class of biomarkers can accurately indicate the severity of cancer

A cancer diagnosis tells you that you have cancer, but how that cancer will progress is a terrifying uncertainty for most patients. Researchers at Cold Spring Harbor Laboratory have now identified a specific class of biomarkers that can tell a lot about how aggressive a patient's cancer will be.

Research pinpoints two proteins involved in creation of stem cells

Mammalian embryos are unlike those of any other organism as they must grow within the mother's body. While other animal embryos grow outside the mother, their embryonic cells can get right to work accepting assignments, such as head, tail or vital organ. By contrast, mammalian embryos must first choose between forming the placenta or creating the baby.

Researchers identify immune cell subset that may drive chronic inflammation

For the first time, researchers have identified that an immune cell subset called gamma delta T cells that may be causing and/or perpetuating the systemic inflammation found in normal aging in the general geriatric population and in HIV-infected people who are responding well to drugs (anti-retrovirals).

Research findings could lead to new targets for cancer-fighting therapeutics

A molecular pathway that's frequently mutated in many different forms of cancer becomes active when cells push parts of their membranes outward into bulging protrusions, Johns Hopkins researchers report in a new study.

New method uses water molecules to unlock neurons' secrets

Neurons are brain cells that communicate with each other by sending electrochemical signals along axons. When a neuron is about to release a signal - in the form of an electric charge - it allows ions to pass through its membrane via ion channels.

Researchers develop new system for efficiently producing human norovirus

An Osaka University-led research team has developed a system for simply and efficiently producing human norovirus. By coaxing human induced pluripotent stem cells to develop into a type of cell that usually lines the intestine, they created a cellular environment that can be used for producing the virus, studying how it interacts with human cells, and investigating potential vaccines.

New study reveals yin-yang personality of dopamine

For decades, psychologists have viewed the neurotransmitter dopamine as a double-edged sword: released in the brain as a reward to train us to seek out pleasurable experiences, but also a "drug" the constant pursuit of which leads to addiction.

Researchers shed new light on how to combat Shiga and ricin toxins

Min Dong, PhD, and his lab are world experts in toxins and how to combat them. They've figured out how Clostridium difficile's most potent toxin gets into cells and zeroed in on the first new botulinum toxin identified since 1969.

Researchers capture high-resolution X-ray and NMR image of key immune regulator

A new study by investigators from Brigham and Women's Hospital provides a biophysical and structural assessment of a critical immune regulating protein called human T-cell immunoglobulin and mucin domain containing protein-3 (hTIM-3).

Ezogabine treatment reduces motor neuron excitability in ALS patients, study shows

Brian Wainger, MD, PhD, of the Healey Center for ALS at Massachusetts General Hospital presented initial, top-level results of a recently completed phase 2 clinical trial of ezogabine (also called retigabine) on December 9 at the Motor Neurone Disease Association annual meeting in Glasgow, Scotland.

Scientists discover cellular mechanism that triggers pneumonia in humans

The situation is relatively common, especially in winter. You come down with the flu, which lasts longer than usual. A few days later, you discover you have pneumonia.

Novel personalized medicine tool for assessing inherited colorectal cancer syndrome risk developed

An international team of researchers led by Huntsman Cancer Institute at the University of Utah has developed, calibrated, and validated a novel tool for identifying the genetic changes in Lynch syndrome genes that are likely to be responsible for causing symptoms of the disease.

Researchers explore how glial cells develop in the brain from neural precursor cells

Two types of cells are active in the brain: nerve cells and glial cells. The latter have long been regarded primarily as supportive cells, but it is increasingly recognized that they play an active role in the communication between neurons in the brain.
