has part has result has agent gene expression by ATF4 [ER stress] ATF4 - transcriptional regulator (canonical)[ER stress - apotosis] Chop expression by ATF4 [ER stress] [ER stress - apoptosis] apoptosis promoting gene expression [ER stress] apoptotic gene expression by ATF4 [ER stress - apoptosis] Inflammatiory gene expression by ATF4 is a subtype of gene expression by transcriptional factor: The process in which a gene sequence is converted into a mature gene product or products (proteins or RNA) related to apoptosis by ATF4. This process is dependent on the apoptosis and can constitute the course of ER stress. PMID:26977301
