The genetic signature of memory

Despite their common involvement in memory, the human cortex and subcortex display a distinct collection of gene signatures. The work recently published in eNeuro increases our understanding of how the brain creates memories ...

Percentage of African ancestry affects gene expression

The percentage of African ancestry in a person's genome determines the level that certain genes are expressed, called mRNA, according to a new Northwestern Medicine study. The discovery could offer insight into the different ...

Building a better flu shot

Each year millions of Americans become sick with the flu, hundreds of thousands are hospitalized and tens of thousands die. Getting the flu shot can reduce the chances of infection. But, at best, the vaccine is only effective ...

Consistent gene changes in Alzheimer's disease across studies

A comparison of mouse Alzheimer's disease models shows changes in the number of cells and the genes they express remain consistent throughout all stages of the disease. The new research published in eNeuro could reveal new ...

Mechanism connects early binge drinking to adult behaviors

University of Illinois at Chicago researchers report that intermittent exposure to high levels of alcohol in adolescent animals leads to increased levels of microRNA-137—a molecule that regulates gene expression in cells—in ...

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.
