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 — The whimsically named sonic hedgehog gene, best known for controlling embryonic development, also maintains the normal physiological state and repair process of an adult healthy lung, if damaged, ... 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

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

First-Aid for Defective Mucus

Oct. 2, 2015 — Proper lubrication is crucial to keep not only machines but also humans functioning smoothly. The mucus membranes in our mouths, eyes, stomachs and genital area help keep friction to a minimum and ... read more

Oct. 2, 2015 — 'Why, Grandma, what big eyes you have!' Though similar in appearance, the hidden cause of those big eyes Little Red Riding Hood notices in Grimms' fairy tale has nothing to do with the ... read more

Fruit Fly Research Reveals Genetic Mechanisms of Dietary Sugar Sensing

Oct. 2, 2015 — A sugar sensing regulatory network, which is composed of several genes, has been identified by researchers. Deregulation of this sugar sensing network leads to severely disturbed energy metabolism. ... read more

Studying Cardiac Arrhythmias in Nematodes

Oct. 2, 2015 — A simple model using the nematode Caenorhabditis elegans has been developed that can be used to test substances for treating genetically-mediated cardiac arrhythmias. They used the nematode feeding ... read more

Study Finds Gaps in Clinical Genetic Counseling Services for Women Undergoing BRCA Testing

Oct. 1, 2015 — Medical researchers have published results from a national study identifying factors and outcomes associated with the use of genetic counseling and testing services for hereditary breast and ovarian ... read more

Tugs and Pulls: How a Molecular Motor Untangles Protein

Oct. 1, 2015 — E. coli ClpB is a bacterial enzyme that untangles proteins. Such tangles are hallmarks of neurodegenerative diseases like Parkinson’s and Alzheimer’s. A study now offers new insight on this ... read more

Genes of Colon Cancer Recurrence Differs Among Blacks, Whites and Asians

Oct. 1, 2015 — The genetic makeup of colon cancer tumors and survival rates for patients with the disease differ by race, according to a study. Colon cancer is the third most common cancer in both men and women ... 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

Five New Genetic Variants Linked to Brain Cancer

Oct. 1, 2015 — The biggest ever study of DNA from people with glioma -- the most common form of brain cancer -- has discovered five new genetic variants associated with the disease. Researchers said their findings ... read more

New DNA Stain Lights Up Living Cells

Oct. 1, 2015 — A new DNA stain that can be used to image living cells has been created by scientists. The new stain works by binding to a part of the DNA helix known as the "minor groove." Once bound, it ... read more
