Searching for novel ATF4 target genes in human hepatoma cells by microarray analysis

Activating transcription factor 4 (ATF4) is a transcription factor with an important biological activity. ATF4 is induced by various stresses, such as endoplasmic reticulum stress, through the phosphorylation of eukaryotic translation initiation factor 2α. ATF4 is also involved in lipid metabolism. In the present study, we performed a microarray experiment to identify new ATF4 target genes, particularly those involved in lipid metabolism, and...
