Abstract
The expression of certain genes has been reported to respond positively to sodium butyrate. This study demonstrates the same feature for two marker genes under the control of five different promoters. In all examples, the stimulatory effect is largest if one or especially two scaffold/matrix-attached regions (SAR/MAR elements) are present adjacent to the gene, and in one case, the stimulation depends entirely upon this situation. These results are observed with several SAR sequences including those obtained by oligomerizing short stretches of DNA surrounding a core motif. It is suggested that butyrate exerts important actions at the level of the chromatin structure.
