The human genome contains about 23,000 genes, but only a fraction of those genes are turned on inside a cell at any given time. The complex network of regulatory elements that controls gene expression ...

New study by Chiba University, Japan in collaboration with Karolinska Institutet, Sweden, uncovers novel enhancer-promoter interactions that regulate gene expression during neuronal differentiation ...

As cells mature and differentiate (right), they use a much more elaborate and cell-type specific ‘switchboard’ to control their gene expression, especially when compared to earlier, immature stages ...

Your skin cells are clearly different from your brain cells even though they both develop in the same person and carry the same genes. They are different because each cell type expresses a particular ...
