Pathways to spatial recognition

When you are lost or disoriented, your brain uses cues from your surroundings—landmarks both near and far—to sort out where you are. The information gathered by your senses is transmitted by nerve cells, or neurons, to ...

Aqueous humor, microRNAs and glaucoma

Glaucoma—the leading cause of vision loss worldwide—includes a heterogeneous group of disorders. Primary open-angle glaucoma (POAG) and exfoliation glaucoma (XFG) are linked to decreased outflow of aqueous humor, which ...

Even DNA that doesn't encode genes can drive cancer

Most of the human genome—98 percent—is made up of DNA but doesn't actually encode genes, the recipes cells use to build proteins. The vast majority of genetic mutations associated with cancer occur in these non-coding ...

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.
