A cross section of a mouse liver lobule under a fluorescence microscope. The middle layer reveals an abundance of messenger RNA molecules (white dots) for the gene encoding hepcidin, the iron-regulating hormone

Tracking gene expression patterns for 20,000 genes in 1,500 cells revealed a mosaic of activities 

The Homebody RNA

Why does some RNA stay in the nucleus rather than rushing off to make proteins? 

Activity of a glucose-manufacturing gene in mouse liver tissue, viewed under a fluorescence microscope. A high concentration of mRNA (red dots) reveals that this activity is highest near a blood vessel (PP) that bathes the tissue in oxygen-rich blood, essential for glucose manufacture

Fits and spurts of gene expression help the liver cope with change
