Gut feeling: A network approach towards understanding IBD

Diseases of the gut are often notoriously difficult to diagnose, nevermind understand, which is where a network-based approach comes in. Rather than trying to understand individual symptoms, or the role of individual genes, ...

Gene expression regulation in Chinese cabbage illuminated

Doctoral student Ayasha Akter (Kobe University's Graduate School of Agricultural Science) and technical staff member Satoshi Takahashi (from the RIKEN Center for Sustainable Resource Science) have revealed the important role ...

Fine-tuning gene expression during stress recovery

Scientists have discovered non-coding RNA has a novel role to fine-tune gene expressions during stress recovery, getting closer to uncovering a 30-year-old nuclear mystery.

New algorithm rapidly finds anomalies in gene expression data

Computational biologists at Carnegie Mellon University have devised an algorithm to rapidly sort through mountains of gene expression data to find unexpected phenomena that might merit further study. What's more, the algorithm ...

Unraveling gene expression

The DNA of a single cell is two to three meters long end-to-end. To fit in the nucleus and function correctly, DNA is packaged around specialized proteins. These DNA-protein complexes are called nucleosomes, and they are ...

Researchers discover molecular light switch in photoreceptor cells

How our eyes detect and respond to changes in light intensity is determined by specialized cells in the eye called photoreceptors. In addition to converting light into electrical signals, effectively allowing us to see, rod-shaped ...

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.
