July 3, 2015 — The DNA molecule is chemically unstable giving rise to DNA lesions of different nature. That is why DNA damage detection, signaling and repair, collectively known as the DNA damage response, are ... read more

July 2, 2015 — Prions are fascinating, enigmatic, and might teach us not only about rare prion diseases like Creutzfeld-Jakob disease, mad cow disease, or scrapie, but also about other more common neurodgenerative ... read more

June 30, 2015 — While studying Yersinia pestis, the bacteria responsible for epidemics of plague such as the Black Death, scientists found a single small genetic change that fundamentally influenced the evolution of ... read more

June 30, 2015 — Recent studies are revealing a complex picture of cancer progression in which certain genes that drive tumor growth in the earlier stages get suppressed in later stages -- taking a step back to move ... read more

June 30, 2015 — Scientists have discovered a new inherited form of obesity and type 2 diabetes in humans. Researchers discovered the new defect by sequencing the DNA of an extremely obese young woman and members of ... read more

Small RNAs Found to Play Important Roles in Memory Formation

June 30, 2015 — A type of genetic material called “microRNA” plays surprisingly different roles in the formation of memory in animal models, researchers have found. In some cases, these RNAs increase memory, ... read more

Understanding Why Animals Are Healthy Offers Path to Precision Medicine

June 29, 2015 — Researchers have identified a mechanism that explains why some mutations can be disease-causing in one genome but benign in another. The researchers compared thousands of human disease-causing ... read more

Blood Test for Lung Cancer a Step Closer

June 29, 2015 — Two oncologists and a research scientist are helping pave the way to an easier, more accurate, less invasive way to screen for the most common form of lung cancer. Lung cancer is the most common ... read more

New Family of Small RNAs Boosts Cell Proliferation in Cancer

June 29, 2015 — Rather than cellular trash, half of a transfer RNA (tRNA) molecule appears to actively spur cell proliferation in breast and prostate cancers, suggesting a new role for tRNA and a possible target for ... read more

Genes Responsible for Increased Activity During the Summer

June 29, 2015 — A thermosensory gene changes behavior in warmer climates, new research reveals. Researchers have explored how the biological clock can be affected by the environment by examining the fruitfly ... read more

Upsetting a Fragile Alliance Triggers a Deadly Childhood Disease

June 29, 2015 — SMA is a devastating neuromuscular disorder that robs children of their ability to walk, eat, or breathe. Mostly caused by an inherited flaw in the Survival Motor Neuron (SMN) gene, SMA is presently ... read more

Scientists Develop More Accurate Whole Genome Variant Discovery, Interpretation

June 29, 2015 — Conventional next-generation sequencing (NGS) techniques are able to accurately detect certain types of variation, such as single nucleotide variants and small insertions or deletions, but miss many ... read more

Pinpointing Mutations in a Relapsed Children's Cancer May Lead to Improved Treatments

June 29, 2015 — Researchers studying the pediatric cancer neuroblastoma have detailed how cancer-driving mutations evolve during chemotherapy, and they hope to exploit this knowledge to design better treatments for ... read more

Rare Gene Variant Associated With Middle Ear Infections

June 29, 2015 — Researchers may have taken the first step on the road to understanding why only some people get frequent painful or chronic middle ear infections. The culprit may be rare genetic variants in a gene ... read more

Genes Leave Some Kids Prone to Weakness in Wrist Bones

June 29, 2015 — Pediatric researchers have discovered gene locations affecting bone strength in wrist bones, the most common site for fractures in children. Children with these genetic variants could especially ... read more

Lean but Not Hungry: Molecular Switch for a Healthy Metabolism Discovered

June 29, 2015 — The protein complex mTORC1 is a central regulator of cell metabolism. In the active state, it stimulates anabolic processes and increases the production and storage of proteins and lipids. ... read more

Genes Add Risk to Depression

June 29, 2015 — People born with a particular gene variant have a greater risk of developing depressions, a recent study shows. Depression has been relatively under-researched, and clinicians are not, generally, ... read more

Action Spectrum of Sun Skin Damage Documented

June 26, 2015 — Scientists have documented for the first time the DNA damage that can occur to skin across the full range of ultraviolet radiation from the sun providing an invaluable tool for sun-protection and the ... read more

RNASEH1 Mutations Impair mtDNA Replication, Cause Adult-Onset Mitochondrial Encephalomyopathy

June 26, 2015 — Next Generation Sequencing (NGS) technology offers an incredible opportunity for the rapid and relatively low-cost characterization of individual genomes, giving us a chance to make a substantial ... read more

June 26, 2015 — Studies on mice reveal that a special protein in the brain's tiniest blood vessels may affect the risk of stroke. Scientists are learning how the blood-brain barrier develops and what makes the ... read more
