Oct. 8, 2015 — Cigarette smoking and heavy alcohol use cause epigenetic changes to DNA that reflect accelerated biological aging in distinct, measurable ways, according to research. The researchers estimated ... read more

'Alarm Clock' of a Leukemia-Causing Oncogene Identified

Oct. 8, 2015 — Mutations in DNMT3A gene cause MEIS1 activacion, triggering leukemia, a research team ... read more

Oct. 6, 2015 — Normal T-cell development requires Notch signaling but hyperactivity can lead to cancer. Drugs that inhibit Notch, such as gamma-secretase inhibitors, are currently being tested in different cancer ... read more

Oct. 5, 2015 — A novel mouse model for the vision disorder Leber hereditary optic neuropathy (LHON) has been developed by researchers who have found that they can use gene therapy to improve visual function in the ... read more

Oct. 5, 2015 — Researchers have determined the structure of a key part of the enzyme telomerase, which is active in most cancers and enables cancer cells to proliferate indefinitely. The new findings reveal how the ... read more

Oct. 5, 2015 — When pathologists perform autopsies on smokers who died with severe emphysema, they find that lungs are black in appearance. Until recently, researchers and physicians could only guess at the ... read more

Oct. 5, 2015 — A smartphone-based device that can reliably carry out molecular diagnoses in under an hour for approximately two dollars per patient has been developed by researchers. The device could enable ... read more

Gastric Bypass Surgery Improves Blood Sugar Handling and Insulin Sensitivity, Study Finds

Oct. 5, 2015 — Gastric bypass surgery can lead to remission of type 2 diabetes along with weight loss. A new study examines why, finding that insulin sensitivity of the body's main glucose (sugar) storage ... read more

Genetic Polymorphism Associated With Lung Cancer Progression

Oct. 5, 2015 — Genetic polymorphisms associated with cancer progression lead to variations in gene expression and may serve as prognostic markers for lung cancer, researchers show. They found that in patients with ... read more

Oct. 5, 2015 — A protein used by tumors to help them detect food supplies has been identified by scientists. Initial studies show that targeting the protein could restrict cancerous cells' ability to grow. ... read more

Oct. 2, 2015 — Researchers have discovered that mothers with high levels of lead in their blood not only affect the fetal cells of their unborn children, but also their ... read more

Oct. 1, 2015 — Tissue-engineered colon derived from human cells is able to develop the many specialized nerves required for function, mimicking the neuronal population found in native colon. These specialized ... read more

Oct. 1, 2015 — A single neuron in a normal adult brain likely has more than a thousand genetic mutations that are not present in the cells that surround it, according to new research. The majority of these ... read more

Oct. 1, 2015 — Our brain cells have different genomes from one another. The study shows for the first time that mutations in somatic cells -- that is, any cell in the body except sperm and eggs -- are present in ... read more

Oct. 1, 2015 — Researchers have identified cellular changes traceable to an RNA splicing factor that's also an oncoprotein that may play a role in converting normal breast cells into tumors. Targeting these ... read more

New Method to Predict Increased Risk of Non-Familial Breast Cancer

Oct. 1, 2015 — By detecting cancer at an early stage, or even predicting who has an increased risk of being affected, the possibilities to treat the disease can be radically improved. Now researchers have ... read more

A Snapshot of Stem Cell Expression

Oct. 1, 2015 — A new study reveals new genes involved in pluripotency, new subpopulations of cells and new methods to find meaning in the data. The findings have implications for the study of early ... read more

New 'Driver' to Assess Cancer Patient Survival, Drug Sensitivity

Oct. 1, 2015 — Cancer specialists have long looked at genetic mutations and DNA copy changes to help predict patient survival and drug sensitivity. A new study has opened up yet another avenue for understanding the ... read more

Oct. 1, 2015 — Researchers have succeeded in an effort to fundamentally improve carbohydrate analysis. With the new method, complex glycans, building blocks of life such as DNA and proteins, can now be sequenced. ... read more
