Abstract: The research progresses in regulation of gene expression by nutrients in recent years are reviewed. Accumulatedevidences indicate that gene expression can be regulated years are reviewed. Accumulated evidences indicate that gene expressioncan be regulated by many nutrients in multi-level and multiform manners. Some nutrients can affect gene expression indirectlyas mediated by hormones or transcriptional factors. The mechanisms of nutrient action are expected to be elucidated at molecularlevel in the future as the research in this field is being conducted continuously.

Key words: nutrient, gene expression
