Gene Expression News and Research

RSS

Gene Expression is the process by which a gene gets turned on in a cell to make RNA and proteins. Gene expression may be measured by looking at the RNA, or the protein made from the RNA, or what the protein does in a cell.

Study helps clarify role of vitamin D in cancer therapy

A colon cancer cell isn't a lost cause. Vitamin D can tame the rogue cell by adjusting everything from its gene expression to its cytoskeleton.

Discovery of key contributor to Alzheimer's disease process

Walter J. Lukiw, PhD, Associate Professor of Neuroscience and Ophthalmology at LSU Health Sciences Center New Orleans, is the lead author of a paper identifying, for the first time, a specific function of a fragment of ribonucleic acid (RNA), once thought to be no more than a byproduct, in regulating inflammation and the development of Alzheimer's disease.

Research sheds light on possible role of DNA packaging in cancer development

MIT biologists have discovered that the organization of DNA's packing material plays a critical role in directing stem cells to become different types of adult cells.

The interaction between genes and behavior

Our DNA determines a lot about who we are and how we play with others, but recent studies of social animals (birds and bees, among others) show that the interaction between genes and behavior is more of a two-way street than most of us realize.

Gene research sheds light on T-cell production

New research, just published by researchers from the University of Georgia, provides the first evidence that a key gene may be crucial to maintaining the production of the thymus and its disease-fighting T-cells after an animal's birth.

Scientists confirm a molecular clipping mechanism behind stem cell development

Stem cells don't just become a part of the liver or the brain in a flash; it takes a complex molecular choreography and requires that specific genes be switched on and off at specific times.

6 Nov 2008

Scientists identify compounds for stem-cell production from adult cells

In the study, the scientists screened known drugs and identified small molecules that could replace conventional reprogramming genes, which can have dangerous side effects.

Discovery of biomarkers for esophageal cancer before it develops

Rhode Island Hospital researchers have identified genetic proteins, also known as biomarkers, capable of distinguishing changes at the microscopic level that can signal a precancerous condition in the esophagus.
