Barcodes Show the Blood Family Tree

Aug. 24, 2016 — By assigning a barcode to stem cells, researchers have made it possible to monitor large blood cell populations as well as individual blood cells, and study the changes over time. Among other things, ... read more

New Small Molecule Compounds Could Treat Ebola Virus Infection

Aug. 24, 2016 — Scientists have found Ebola's Achilles' heel: a new kind of chemical compound can block the protein Ebola uses to break out of cells and infect new cells. The compounds could potentially be ... read more

In Some Genetic Cases of Microcephaly, Stem Cells Fail to Launch

Aug. 24, 2016 — In a very severe, genetic form of microcephaly, stem cells in the brain fail to divide, according to a new study that may provide important clues to understanding how the Zika virus affects the ... read more

A New Path for Killing Pathogenic Bacteria

Aug. 24, 2016 — Bacteria that cause tuberculosis, leprosy and other diseases, survive by switching between two different types of metabolism. Scientists have now discovered that this switch is controlled by a ... read more

Mechanism That Alters Neural Excitability Offers Window Into Neuropsychiatric Disease

Aug. 23, 2016 — Researchers show, for the first time, that the well-known mechanism of gene expression control -- dynamic changes in DNA methylation -- is also involved in changes to the excitability of neural ... read more

New Zika Clone Could Be New Model for Developing Vaccine

Aug. 23, 2016 — Stopping the explosive spread of Zika virus -- which can lead to birth defects in babies born to infected mothers -- depends on genetic insights gleaned through new tools and models. Researchers ... read more

Esophageal Cancers Driven by 'Marginal Gain' Rather Than Speed

Aug. 22, 2016 — Scientists have shown that unexpectedly, esophageal cancer cells do not divide faster than their normal neighbors. But unlike normal cells, the tumor cells produce slightly more dividing daughter ... read more

Transcription Factor Foxn1 and Preserving Immune Function in Later Life

Aug. 22, 2016 — Researchers use new experimental models and analytical tools to investigate genes regulated by Foxn1, becoming the first to identify the DNA sequence bound by the transcription factor. Among the ... read more

Aug. 22, 2016 — In doses equivalent to those used regularly in human children, antibiotics changed the mix of gut microbes in young mice to dramatically increase their risk for type 1 ... read more

Two Key Proteins Preserve Vital Genetic Information

Aug. 22, 2016 — New research demonstrates how two key proteins mediate the organization of chromosomes and our genome, shedding light on one of the key genetic processes for every person. With this key basic ... read more

Answering the Call for Quality Colorectal Cancer Patient Info

Aug. 22, 2016 — Patients depend on the Internet for health information, but when it comes to colorectal cancer, currently available resources are not meeting their ... read more

Increased Eye Cancer Risk Linked to Pigmentation Genes That Dictate Eye Color

Aug. 19, 2016 — New research links specific inherited genetic differences to an increased risk for eye (uveal) melanoma, a rare form of melanoma that arises from pigment cells that determine eye color. scientists ... read more

The First Stage of the Cascade

Aug. 19, 2016 — G proteins are molecular switches on the insides of cell membranes. They convey important signals to the inner workings of the cells. The associated receptors are targeted by all kinds of ... read more

'Born to Be Bad' or 'Born to Be Benign:' Testing Cells for Esophageal Cancer Risk

Aug. 19, 2016 — Genetically analyzing lesions in the food pipe could provide an early and accurate test for esophageal cancer, according to research. Barrett's Esophagus is a common condition that affects ... read more

In Cells, Some Oxidants Are Needed

Aug. 18, 2016 — Some studies are showing that reactive oxygen species (ROS) molecules sometimes can aid in maintaining health -- findings now boosted by a surprising discovery from the ... read more

Aug. 18, 2016 — A profound new level of complexity and interaction among genes within specific tissues responsible for mediating the inherited risk for cardiometabolic diseases have been identified by researchers, ... read more

Uncovering a New Pathway to Halting Metastasis

Aug. 18, 2016 — New research could lead to new therapies to treat patients who suffer from metastatic disease, report scientists. Metastasis, the process by which cancer cells leave the primary tumor and spread to ... read more

How Genomic Sequencing May Be Widening Racial Disparities in Cancer Care

Aug. 18, 2016 — As scientists learn more about which genetic mutations are driving different types of cancer, they're targeting treatments to small numbers of patients with the potential for big payoffs in ... read more

New Strategy to Reverse the Disease Dyskeratosis Congenita

Aug. 18, 2016 — A link between telomeres and a molecular signaling cascade called the Wnt pathway has been identified by researchers, which may point to a treatment option for dyskeratosis congenita patients. ... read more

Unexplained Developmental Disorder Linked to Gene Involved in Essential Cellular Processes

Aug. 18, 2016 — A neurodevelopmental disorder for which there was no known cause has been linked to SON, a gene that is involved in essential mechanisms a cell uses to translate DNA into protein, as well as in DNA ... read more
