Renegade genes caught red handed

The guardians of the human genome that work to prevent potentially disease-causing gene expression might not be as effective at their jobs as previously thought, according to new University of Arizona research.

Research suggests new approach for treating inflammation

Medications that mitigate inflammation caused by a variety of diseases including rheumatic arthritis may also compromise a person's immune system, but a new approach points to a possible solution to this problem.

How your DNA takes shape makes a big difference in your health

The more we learn about our genome, the more mysteries arise. For example, how can people with the same disease-causing mutation have different disease progression and symptoms? And despite the fact that it's been more than ...

Zebrafish aid effort to regenerate damaged retinas

The tiny zebrafish may hold the secret to regenerating damaged retinas in humans, Vanderbilt University researchers reported last week in the journal Cell Reports.

Researchers explore origins of neuron diversity

SMU (Southern Methodist University) researchers have discovered another layer of complexity in gene expression, which could help explain how we're able to have so many billions of neurons in our brain.

How natural genetic differences can affect heart health

The biggest risks for cardiovascular disease are smoking and poor diet. However, different people are more susceptible to heart disease based on very slight differences in their genes, called variants. While there have been ...

Researchers move beyond sequencing and create a 3-D genome

Like pirates on a treasure hunt, St. Jude Children's Research Hospital scientists have created the first 3-D map of a mouse genome and used it to discover scientific gold. The gold includes insight from machine learning into ...

Gene expression

Gene expression is the process by which information from a gene is used in the synthesis of a functional gene product. These products are often proteins, but in non-protein coding genes such as rRNA genes or tRNA genes, the product is a functional RNA.

Several steps in the gene expression process may be modulated, including the transcription, RNA splicing, translation, and post-translational modification of a protein. Gene regulation gives the cell control over structure and function, and is the basis for cellular differentiation, morphogenesis and the versatility and adaptability of any organism. Gene regulation may also serve as a substrate for evolutionary change, since control of the timing, location, and amount of gene expression can have a profound effect on the functions (actions) of the gene in the organism.
