There's more to oxytocin, the so-called love hormone

A new study published in Nature Communications reveals that the role of the hormone oxytocin may extend beyond childbirth and social behaviour. By analysing gene expression maps and brain activation patterns, researchers ...

Uncovering the evolution of the brain

What makes us human, and where does this mysterious property of "humanness" come from? Humans are genetically similar to chimpanzees and bonobos, yet there exist obvious behavioral and cognitive differences. Now, researchers ...

Blood leukocytes mirror insufficient sleep

An insufficient amount of sleep and qualitatively poor sleep are common among the general population. Prior studies have indicated that prolonged insufficient sleep and poor sleep quality are associated with a heightened ...

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.
