From: Nrf2 target genes are induced under marginal selenium-deficiency
mRNA expression of selenoproteins in the colon (n = 9) and duodenum (n = 6) of selenium-poor (−Se) relative to selenium-adequate (+Se) mice. a Thioredoxin reductase 1 (Txnrd1), b glutathione peroxidase 2 (Gpx2), c selenoprotein W (Sepw1). Gene expression was analyzed by qPCR and normalized to Rpl13a in the duodenum and to the mean of the reference genes Hprt1 and Rpl13a in the colon. *P < 0.05; **P < 0.01; versus +Se set to 1 analyzed by unpaired Student’s t-test
