Finally, the alternative first exon (E1b) encodes the N-terminal part of the nuclear isoform, n-GPx4, and contains a nuclear targeting sequence which is apparently retained after nuclear import (Pfeifer et al., Figure 1 Unexpected DHA-induced transcriptional regulation of Gpx4 gene We have recently reported that DHA upregulates several members of both glutathione/glutaredoxin and thioredoxin/peroxiredoxin antioxidant systems in mouse hippocampal HT22 cells (Casaas-Snchez et al., Gpx4 isoforms, around 150%, and affecting all transcripts analyzed, including the mitochondrial, cytosolic, and nuclear isoforms

Physiologically, the secretion of growth hormone (GH) in somatotrophs is stimulated mainly by growth hormone-releasing hormone receptor-Gs signaling and partially by ghrelin receptor-Gq signaling, whereas somatostatin inhibits GH secretion by activating somatostatin receptor (SSTR)-Gi signaling 12,13
